Parents Can Foster Healthy Eating Habits in Children

Nancy Bostock, a pediatrician at Cambridgeshire and Peterborough NHS Foundation Trust, is deeply concerned about the conflicting messages regarding food that children and parents receive. With her expertise in children’s weight management and mental health, she has co-led the creation of innovative food strategies. For more information, visit Cambridge Children’s Hospital.

“I worry that parents may feel overwhelmed by advice from various sources, leading them to adopt practices that might not serve their children’s best interests,” Bostock explains. In her interview with New Scientist, she shares six straightforward, science-based strategies to help children cultivate a healthy relationship with food.

1. Emphasize the Social and Emotional Dimensions of Eating

Eating, parenting, and anxiety are intertwined. This can manifest early in life. Some families experience food insecurity shortly after the birth of a child, pressuring parents to breastfeed. While breastfeeding is undoubtedly beneficial, it is also crucial for the mother’s mental health. Common early-life challenges such as hypoglycemia and jaundice can induce parental guilt over inadequate nourishment.

This stress often leads parents to excessively monitor their children’s eating habits, overshadowing the fundamental relationship between children and food. Remember, most children will eat when hungry and drink when thirsty.

Many parents fret about whether their children drink enough water. However, as long as your child is thriving, there’s no need to constantly check their hydration levels. Trust your child’s instincts.

Additionally, consider the social dynamics of family meals. Reflect on mealtime experiences: do you all eat together? Are meals enjoyable and relaxed? Foster a positive and communal atmosphere surrounding food.

2. Avoid Saying, “I Can’t Eat the Dessert Until I Finish My Dinner.”

Allowing children to regulate their own appetite fosters healthier eating habits as they grow. Minimize parental interference: promote that food is a source of nourishment and energy, and let your child understand their bodily needs.

Statements like “you can’t have dessert until finishing dinner” can lead to unhealthy binge eating. If dessert is always sweet and rich, children might favor less nutritious foods over time, sending a negative message about enjoying food. Instead, serve dinner followed by fruit if desired.

3. Refrain from Imposing Unnecessary Dietary Restrictions

Amidst abundant dietary advice, parents often seek guidance from nutritionists or behavioral specialists to manage children’s eating habits. However, many recommendations to restrict particular foods lack medical foundation. For instance, enforcing a gluten-free diet without celiac disease could have negative effects, including fiber loss and nutrient deficiencies.

Moreover, outright banning certain foods can create a perception of them being “unsafe.” Research suggests that a healthier approach is to prioritize the intake of nutrient-rich foods—fiber, fruits, vegetables, and whole grains—over eliminating food groups.

4. Prevent Children from Using Food for Manipulation

Parents often worry about their children’s eating habits or how their behavior might change if they don’t eat enough. Kids quickly pick up on their parents’ concerns and may manipulate situations with food. Phrases like “If I don’t have ice cream right now, I’ll be sad” can escalate the situation and, if parents give in, this only reinforces bad behavior. Instead, communicate that eating is for energy and health, not a bargaining tool. Offer choices without pressure, like fruit or yogurt if they don’t want the main meal.

5. Recognize That Likes and Dislikes Are Normal

It’s normal for children to become picky eaters as they develop. Research shows that a significant percentage of preschoolers exhibit selective eating behaviors. This phase helps children differentiate safe from unsafe foods. Rather than imposing restrictions, present new foods without pressure; studies suggest children typically need about 15 positive exposures to a new food before accepting it.

While it’s essential to avoid foods known to cause allergies, continued exposure to a range of foods is crucial for health, environmental sustainability, and diverse life experiences. Offer variety and understand that tolerance can precede acceptance.

6. Reflect on Your Own Eating Behaviors

Children mirror their parents’ attitudes and beliefs about food. It’s vital to model healthy perspectives. If you express negativity about your body or weight, children may internalize similar thoughts. Evidence shows kids often adopt their parents’ biases. Hence, the best way to nurture a positive relationship with food and body image in your child is to cultivate one in yourself.

As narrated by Helen Thomson

If your child’s diet is excessively restricted, or if they are not growing or gaining weight appropriately, please consult a healthcare professional.

Discover What a Healthy Gut Microbiome Looks Like

Posted on by
Reply

The trillions of microorganisms that inhabit our intestines significantly impact our health.

We frequently hear about the benefits of certain foods for your microbiome and overall health. However, the exact composition of a healthy gut microbiome has not been fully understood until now. A recent study involving over 34,000 individuals has advanced our knowledge of the microbial combinations that indicate low inflammation, robust immunity, and healthy cholesterol levels.

The gut microbiome influences various aspects of health, including the immune system, aging, and mental well-being. While many home testing kits claim to analyze gut composition, their effectiveness remains questionable, as defining a “healthy” microbial balance is complex.

Earlier efforts have mainly concentrated on species diversity, under the assumption that a greater variety of bacteria is beneficial. However, since microbiomes differ significantly between individuals, pinpointing specific microbial communities linked to particular health outcomes is challenging.

“The interplay between our diet, gut microbiome composition, and health is intricate. The only way to unravel these connections is through large sample sizes,” explains Nicola Segata from the University of Trento, Italy.

To develop a comprehensive understanding, Segata and his team analyzed data from over 34,500 participants in the PREDICT program, conducted in the UK and the US by the microbiome testing company Zoe, and cross-referenced the findings with data from 25 additional cohorts in Western nations.

Among the thousands of bacterial species in the human gut, researchers focused on 661 species present in over 20% of Zoe participants. They identified 50 bacteria closely linked to health markers, such as BMI and blood glucose levels, as well as 50 associated with poor health.

The 50 “good” bacterial species (22 of which are newly identified) seem to affect four key areas: inflammation and immune function, body fat distribution, and blood sugar regulation.

Healthy participants, with no known medical issues, carried approximately 3.6 more of these beneficial species than those with health conditions, while individuals at a healthy weight had about 5.2 more species compared to those who were obese.

Researchers propose that the gut microbiome plays a crucial role in releasing chemicals that influence health outcomes, including cholesterol transport, inflammation reduction, fat metabolism, and insulin sensitivity.

Among the species analyzed, most bacteria classified as either “good” or “bad” belong to the genus Clostridium. Within this group, 40 species from the family Lachnospiraceae were highlighted; 13 showed positive impacts while 27 were linked to negative effects.

“This research identifies a subset of bacteria worth further exploring for their potential impacts on health conditions like high blood sugar and obesity,” states Ines Moura from the University of Leeds, UK.

The connection between these microorganisms and diet is analyzed through food questionnaires and data collected via the Zoe app, which suggests aiming for at least 30 different plant types each week and consuming three servings of fermented foods daily, promoting fiber intake and reducing ultra-processed food consumption.

The findings indicate that most microorganisms tend to enhance health with a balanced diet or exacerbate health issues with a poor diet. However, 65 of the 661 microorganisms exhibited an inconsistent relationship.

“These 65 bacteria highlight the complexity of our microbiome,” remarks Segata, who also consults for Zoe. “Their effects might depend on the presence of other microorganisms, specific bacterial strains, or particular dietary factors.”

This classification of “good” and “bad” bacteria enables researchers to assess an individual’s gut health on a scale from 0 to 1000, which is already being applied in Zoe’s gut health assessments.

“Think of a healthy gut microbiome as a network of chemical factories. We need a diverse range of species and a predominance of beneficial bacteria to generate health-promoting chemicals that benefit the entire body,” says Tim Spector, PhD from King’s College London and co-founder of Zoe.

Nonetheless, establishing a definitive model of a healthy gut microbiome is challenging. “Defining a healthy microbiome is not straightforward, as gut composition is impacted by diet and can shift due to environmental factors, age, and health conditions requiring long-term treatment,” adds Moura.

“We need to view our bodies and microbiomes as two intricate systems that combine to create an even more complex system,” says Segata. “A change in one element can subtly affect everything else. Understanding the causative relationships is often quite complicated.”

Segata advocates for larger studies to further clarify these links and represent a wider global population. However, once a health and microbiome baseline is set, he believes it should be feasible to recommend specific foods to optimize gut bacteria.

The Importance of Staying Healthy After 40 (and How Anyone Can Achieve It)

Posted on by
Reply

As soon as you exit the school environment, physical activities like sports and exercise cease to be mandatory. If you’ve allowed your kids a long hiatus since then, you’re overlooking the numerous advantages that consistent exercise can offer.

If you’re over 40, you might have fallen into the mindset that the benefits of fitness are a lost cause. Physical wellness was dismissed long ago, and the thought of reclaiming it seems futile.

However, this belief is misguided.

Even if you’ve adopted a sedentary lifestyle, increasing your movement can lead to substantial health improvements.







In recent studies published in the British Journal of Sports Medicine, researchers discovered that adults who exercised regularly had a 30 to 40 percent reduced risk of dying from any cause later in life.

Moreover, individuals who transitioned from inactivity to activity were 22 percent less likely to die compared to those who remained sedentary.

Earlier studies featured in JAMA Cardiology revealed that over 300,000 participants showed that those who became active after 40 enjoyed the same health advantages as lifelong active individuals.

Science confirms: it’s never too late to embark on a transformative journey.

However, if exercise has been a lower priority for the past 10-20 years, consider starting gradually, rather than preparing for a marathon.

If you’re a heavy smoker, drinker, or significantly overweight, consulting your doctor before initiating a new regimen may be wise.

How can I get started?

Walking is often regarded as one of the finest forms of exercise, according to Stacey Clemes, a Professor of Active Living and Public Health at Loughborough University, UK.

“It has minimal impact on your body, thus lowering the risk of injury. It’s free, and you don’t require special equipment. As long as you have comfortable shoes, you’re good to go.”

Through her research, she has collaborated notably with sedentary populations, such as truck drivers, aiding them to boost their activity levels.

She discovered that fitness trackers and pedometers are invaluable tools for individuals monitoring their exercise.

“It’s quite beneficial to visualize your progress, be it through step count or daily walking hours.” [data] “Using data to establish goals is also an effective strategy,” she adds.

Instead of comparing yourself to others, Clemes encourages building your activity incrementally.

“If you averaged 4,000 steps daily last week, aim for 4,500 this week. There’s robust evidence that even slight increases can lead to health improvements. The key message is to gradually do a bit more and maintain that progression.”

Now, regarding the often-cited goal of 10,000 steps daily—sounds daunting, right?

You may find relief knowing that recent research published in The Lancet indicates that merely 4,000 steps per day correlate with notable health improvements compared to 2,000 steps.

Health benefits continued to increase until reaching 7,000 steps.

Professor Stephen Harridge, the director of the Center for Human and Applied Physiology at King’s College, London, advises starting with attainable goals.

“If you’re completely inactive, begin with something small. Walk to the next bus stop instead of waiting at the nearest one. Opt for the stairs over the elevator.”

“Simple yet effective actions that elevate your overall activity can significantly benefit your muscles, metabolism, and heart health.”

How can I avoid injury?

Rather than leaping into an intense training program, it’s wise to gradually lift your activity level to lower your chance of injury.

Injuries not only inflict pain but also demoralize you, making it harder to stay committed to a new exercise routine.

Resuming exercise can be especially tricky for those who were once active in their 20s but paused for life’s demands, says Miho Tanaka Sensei, Director of the Women’s Sports Medicine Program at Massachusetts General Hospital and an Associate Professor of Orthopedics at Harvard Medical School.

“Many feel they can return to their previous training regimen from their 20s,” she explains.

“The challenge lies in the fact that your 40s body responds differently compared to your 20s body; it won’t adjust in the same way to the training methods that may have worked two decades ago.”

This variation occurs as muscle mass begins to decline after 30, decreasing by 3 to 8 percent every decade and accelerating after 60.

Additionally, collagen found in muscles, joints, and tendons begins changing after 30, leading to decreased elasticity.

Thus, it’s crucial to set aside your ego. Attempting to hit previous records may lead to injury—be kind to yourself.

“The margin for injury is smaller, and recovery takes longer,” Tanaka states. “It merely slows your recovery from inflammation.”

For those new to exercise, Tanaka recommends low-impact activities such as swimming and cycling. These pursuits provide cardiovascular benefits while minimizing joint strain.

From there, you can gradually progress to activities like hiking before attempting high-impact exercises that exert stress on your joints, like running or CrossFit.

Aiming for 150 minutes of moderate aerobic exercise or 75 minutes of vigorous aerobic exercise weekly maximizes benefits, enhancing cardiovascular health while reducing the risk of diabetes and certain cancers.

What types of exercises should I include?

To promote comprehensive health, incorporating resistance training several times a week is essential to combat the natural decline of muscle and bone mass that accompanies age. It’s about more than just bicep curls!

Strengthening your core and back muscles is also crucial.

The good news is that you don’t need to purchase extravagant gym memberships or trendy workout gear to perform these exercises.

Bodyweight exercises like planks, squats, and push-ups are highly effective and can be done at home. The NHS offers some excellent examples on their website.

Tanaka emphasizes that individuals over 40 shouldn’t overlook stretching. “Flexibility and range of motion can diminish,” she points out.

“To function well, whether playing tennis or running efficiently, your joints require adequate range of motion. As you age, this tends to decrease, and stretching can help.”

How can I fit exercise into my routine?

If this all feels overwhelming, considering that many people in their 40s juggle demanding careers, long commutes, childcare, and elder care, here’s a supportive note: studies have shown that consolidating exercise into weekends yields similar benefits as spreading it throughout the week.

This is based on a study involving 64,000 participants aged 40 and above tracked for 18 years.

Researchers found that “weekend warriors” who exercised once or twice weekly were able to lower their cardiovascular disease risk by 41 percent and cancer mortality risk by 18 percent compared to non-exercisers.

In comparison, regularly active people (three or more days a week) experienced a similar reduction in risks—41 percent for cardiovascular disease and 21 percent for cancer.

Still skeptical? All experts agree: the most crucial factor is finding an exercise you genuinely enjoy, ensuring sustained participation.

If running isn’t your thing, perhaps dancing piques your interest? Did you enjoy kickabouts during school? Why not consider walking soccer?

To conclude, Harridge reassures us that it’s entirely feasible to be more physically fit in your 40s than you were in your 20s or 30s.

But he emphasizes that it’s not about reversing aging; it’s about eliminating the detriment that comes from inactivity and getting back on track.

“It’s never too late,” he affirms. “If you’re 40, there’s ample time for life-changing transformations!”

Just 1% of the Global Population Follows Healthy and Sustainable Eating Habits, Major Report Reveals

Posted on by

Here’s a rewritten version of your content while keeping the HTML tags intact:

Recent global assessments of the food system reveal that fewer than 1% of individuals consume diets beneficial to both the planet and human health.

Nevertheless, adopting a healthier dietary approach could prevent up to 15 million premature deaths annually and could decrease global greenhouse gas emissions by as much as 20%.

The findings are part of a 2025 Report by the Eat-Lancet Committee, which consolidates insights from nutritionists, climate experts, economists, physicians, social scientists, and agricultural scholars from over 35 countries.

The research team evaluated the effects of current food systems on human health and the environment, concluding that food production poses risks to five crucial Earth systems that are essential for human survival.

These five critical threats include climate change, land degradation, water scarcity, nitrogen and phosphorus pollution, and human-induced contaminants like pesticides and microplastics.

However, transforming the food system to ensure healthy diets for everyone could restore these systems to a safe state and enhance human well-being.

“If everyone adopts a healthy diet, by 2050, 100 billion people could sustain themselves on 7% less land than what is currently utilized,” stated Dr. Fabrice Declerck, EAT’s Chief Science Officer, in an interview with BBC Science Focus. “This has never happened in the history of food production. We have very few resources needed to feed more individuals.”

Scientists have estimated that 6.9 billion individuals consume excessive amounts of food, particularly meat, dairy, sugar, and ultra-processed items, while 3.7 billion struggle to find access to nutritious food.

As a result, the report advocates for adherence to a planetary health diet (PhD), which emphasizes fruits, vegetables, nuts, legumes, and whole grains.

In a PhD, half of your plate should consist of vegetables, fruits, and nuts, while 30% should be dedicated to whole grains. The remaining portion should be a protein source, with a focus on legumes like beans and lentils.

Meat, fish, and dairy are optional within the PhD framework, with established limits, but the diet allows for flexibility. For instance, one can remain within guidelines even with a weekly intake of up to 200g of beef.

Declerck notes that the diet is adaptable to individual tastes, encouraging people to incorporate their cultural preferences.

“In fact, I believe traditional diets often more accurately reflect health,” he mentioned.

Currently, only 1% of individuals meet the report’s dietary suggestions. Declerck emphasized that scientists are not ready to pinpoint the locations of these individuals, given the numerous variations among countries.

“But these individuals reside in societies where they can access healthy diets and earn a livable wage,” he added.

Declerck further remarked that the best examples of healthy eating are often found in middle-income countries, particularly within the Mediterranean basin, the Indian subcontinent, and Southeast Asia.

For middle-income nations, the challenge lies in avoiding a shift toward a Western diet while maintaining cultural dietary traditions.

Amidst concerns regarding the climate crisis, Declerck stated that the report presents a “surprising” opportunity to enhance both human health and environmental well-being simultaneously.

“We encourage individuals to consume a wider variety of foods, celebrate their own cultural contributions, explore diverse culinary traditions, and enjoy the richness of food diversity,” he asserted. “This is beneficial not only for your personal health but also contributes significantly to the health of our planet as a whole,” Declerck concluded.

The research’s co-author, Professor Johann Lockstrom, co-chair of the committee and director of the Potsdam Institute for Climate Impact Research, stated: “The evidence is irrefutable. It is not only feasible to transform the food system, but it is crucial for ensuring a safe, fair, and sustainable future for all.”

Justice formed another key component of the report, highlighting the fact that the wealthiest 30% of the population accounts for over 70% of food-related environmental impacts.

“Those of us who are unhealthy and walk blocking others’ rights to a secure environment must take action,” the report emphasized.

The findings call for immediate measures to reform the global food system for the benefit of human health, justice, and environmental sustainability.

Longevity Diet: Discover How Healthy Eating Can Extend Your Life by a Decade

Posted on by

When centenarians are asked about their longevity, the common reply centers on diet. For instance, Maria Blañas Morela, the oldest known person when she passed at 117, consumed three yogurts daily. Jeanne Calment, often recognized as the oldest living person, attributed her remarkable age to olive oil, chocolate, and the occasional glass of port.

Diet plays a significant role in health and is essential for a long life. However, a better question to consider might be: “What did you avoid eating?”

This article is part of a special issue examining ways to achieve the healthiest and happiest year possible. Click here for more details!

For example, Lars Fadness from the University of Bergen in Norway and colleagues analyzed research from the global burden of disease report. Their findings indicate that a conventional Western diet—characterized by lower intake of refined grains, sugar, red and processed meats, and dairies, alongside lesser fresh fruits, vegetables, nuts, and fish—is not conducive to longevity. In fact, such diets contribute to approximately 11 million early deaths annually.

Researchers modeled the life expectancy impact of dietary changes, showing that if a typical 20-year-old woman in the US shifts to a diet focused on whole grains, fruits, vegetables, nuts, legumes, and fish, her life expectancy could rise from 80 to 89. Similarly, a 20-year-old man making the same dietary switch would see an increase from 76 to 86.

“Increasing whole grains, nuts, and legumes while minimizing processed and red meat can significantly improve health,” Fadness notes.

“
Even if your 20th birthday is long gone, there are compelling reasons to make a change
“

Even if you’re past 20, there’s still value in changing your habits. For instance, a 60-year-old woman switching to this healthier lifestyle could gain over seven extra years, raising her life expectancy from 81.6 to 89.

Fadness also detailed how transitioning towards a diet less aligned with Western standards can extend life expectancy, albeit to a lesser degree than complete dietary optimization.

Eating lots of fresh vegetables can add years to your life

NRD/UNSPLASH

While these are theoretical models, real-world data supports the premise that diet plays a significant role in health over the years.

Last year, Zhaoli Dai-Keller and her team at the University of New South Wales investigated the nutritional habits of thousands of people aged 95 and older, focusing on individuals from community environments in East Asia, Australia, and Western Europe. These individuals have successfully aged, and their dietary patterns revealed valuable insights.

Avoid Excess Salt

The study found that those individuals exemplified dietary virtues. They consumed significantly less alcohol and adhered to a balanced, diverse diet featuring primarily fruits, vegetables, white meat, fish, and legumes. Notably, Dai-Keller highlighted, “Salt intake was notably lower among centenarians.” High salt consumption is linked to cardiovascular diseases, a leading cause of death globally.

In a related study, Anne Julie Tessier and Marta Guasch-Ferré from the Harvard Chan School of Public Health, reexamined data from two extensive studies that tracked over 105,000 individuals spanning three decades, searching for evidence of healthy aging, defined as reaching age 70 free from major chronic diseases and maintaining physical and mental acuity.

Only about 10% of participants met these criteria. Analysis showed that a key commonality among those who reached this goal was dietary habits, with the majority consistently following a Mediterranean diet during middle age. In contrast, those who indulged in fatty, salty, and meaty diets did not fare as well in aging healthily.

While reaching the age of 70 in good health does not guarantee a lifespan of 100, it certainly helps.

So, how much does body weight influence longevity, beyond simply what you eat? According to a 2024 study led by Dai-Keller, one defining characteristic of those over 95 is that they tend to be slender. Approximately half maintained normal weight, while a third experienced weight loss.

Weight and Daily Activities

Obesity does not appear to be a conducive factor for reaching 100 years. However, research showed that being overweight, as opposed to being obese, was beneficial for daily functions compared to maintaining a normal weight. Additionally, being underweight increased the risk of disability by about 25%.

This discussion leads us to calorie restriction, a method sometimes recommended for promoting longevity. One of the most reliable ways to prolong the lifespan of laboratory animals is to reduce caloric intake by over 25%. However, this is challenging for humans, and calorie restriction is yet to be proven effective in extending human lifespan. Even if it does extend life, it may compromise the ability to perform daily tasks.

In conclusion, to enhance your chances of living to 100 in optimal health, consider the crucial elements on your plate.

Unseen Belly Fat Might Be Accelerating Your Aging Mind — Even If You’re at a Healthy Weight

Posted on by

Recent studies indicate that visceral fat (the concealed belly fat located deep within the abdomen) may contribute to the accelerated aging of your heart.

In contrast to subcutaneous fat, which resides just beneath the skin, visceral fat envelops vital organs like the stomach, liver, and intestines. Individuals with elevated visceral fat levels might present as slimmer or even possess a healthy body mass index (BMI) and weight.

“Staying active is crucial, but our findings reveal that this hidden fat can pose risks even for those who seem healthy,” states Professor Declan Olegan, who led the research.

This research has been published in European Heart Journal. Scientists at the Medical Research Council of London (MRC) Institute of Medical Sciences examined data from 21,241 participants in the UK Biobank.

Whole-body imaging was utilized to analyze fat distribution, along with an in-depth investigation of the heart and blood vessels. Artificial intelligence was implemented to estimate a “heart age” for each participant, reflecting signs of organ aging, such as hardened or inflamed tissue.

The study identified notable differences between genders. Men are prone to accumulating visceral fat in the abdomen, often resulting in expedited heart aging.

Conversely, women have a genetic tendency to store fat around the waist and thighs, resulting in a “pear shape,” which may decelerate heart aging. Elevated estrogen levels in premenopausal women are linked to reduced heart aging, indicating that hormones might play a significant role in organ protection.

Blood analyses revealed a correlation between visceral fat and increased inflammation, suggesting another factor that could contribute to premature aging.

Professor Brian Williams, Chief Science Officer and Medical Officer at the British Heart Foundation, stated: “We are already aware that excess visceral fat around the heart and liver can result in increased blood pressure and high cholesterol, which may further accelerate heart and blood vessel aging.”

“The typical pattern of fat distribution observed in women is influenced by estrogen, suggesting that hormones could be pivotal in developing future treatments for cardiac aging.

“Adopting healthier eating habits and increasing physical activity can aid in lowering visceral fat levels.”

Mark Twain famously remarked, “If you were born at the age of 80 and gradually refined down to 18, life would be perpetually joyous.” The quest for youth has captivated stories and myths throughout the ages; what if we could finally achieve it?

Recent research indicates that the GLP-1 medication Ozempic, containing semaglutide, might effectively reverse biological aging by around three years. This effect is notably observed in the brain, suggesting that medications like Ozempic could help mitigate conditions such as dementia. Additionally, it seems to reduce inflammation tied to various health concerns, including heart disease, chronic pain, and depression.

Originally developed for type 2 diabetes, semaglutide has changed the landscape of obesity treatment. It’s important to highlight that its anti-aging effects are particularly noted in individuals with HIV-related fat hypertrophy, though researchers believe its benefits may extend to a broader population.

Ozempic seems to have eradicated the inflammatory system associated with numerous health conditions.

It’s intriguing to consider whether we should all be using these drugs to reverse aging and reap the rewards of better health. However, we cannot assume this is wise without substantial evidence from large placebo-controlled trials involving healthy individuals. Conducting such studies may be contentious, as there are potential side effects to monitor. Moreover, when supplies are limited, it’s crucial to prioritize those in dire need.

Nevertheless, it appears that a number of healthy individuals are already utilizing these medications—largely “off-label”—without clarity on their safety. Future research should unveil a clearer understanding of these risks and provide insights into how weight loss affects muscle mass retention.

As the array of health advantages associated with these drugs continues to expand, it may be time to investigate their efficacy in healthy individuals, aiming to determine if they genuinely have the capacity to slow aging rather than speculating about youthful elixirs.

Parents, Stay Calm: Achievable Tips for Healthy Screening Times for Kids | Kaitlyn Regehr

Posted on by
Reply

this summer, technology secretary Peter Kyle revealed that he is contemplating a two-hour “screen time” limit for children’s use of social media apps. This approach is not just insufficient; it has become outdated.

While the timing of this announcement is appropriate, coinciding with the onset of summer holidays and the imperative for parents to oversee their children’s safety in digital spaces, it is rooted in older screen time recommendations. While it’s vital to think about limiting screen time, the suggested cap only addresses usage duration without considering quality. Thankfully, as someone who teaches digital literacy and is also a parent, I recognize there are ways to cultivate healthier habits for our children this summer, even if the government hasn’t fully adapted yet.

Screen time limits have dominated the discourse on digital engagement for parents, educators, and society over the past decade. This guidance emerged after research indicated that increased screen time correlates with a higher risk of obesity among children and adolescents. While this was beneficial advice for promoting physical health, it failed to robustly address how the nature and quality of online content impact mental health.

For instance, adhering to this guidance allows one child to enjoy CBeebies alongside their family, stimulating conversation, while another child is isolated with headphones, consuming algorithm-driven YouTube Shorts. The existing “Screen Time” guidance treats both scenarios equivalently. However, they are qualitatively distinct. In the first case, one child experiences interactive and communal viewing with a parent, fostering discussion and connection, while the other child’s viewing experience remains isolated and fragmented. They consume short-form content with limited narratives and character development, often lacking regulatory oversight.

YouTube has become a primary platform for our children’s screen time and is now the leading choice for Generation Alpha’s first television experience. Remarkably, 88% of UK children aged 3 to 17 are using the platform. Yet, YouTube is often overlooked in discussions about social media restrictions, including in Kyle’s statement.

Attempts have been made to differentiate between types of screen time, such as “passive” versus “active” engagement. The Royal College of Pediatrics and Child Health aims for policies that emphasize habits and behavior, categorizing “active screen time” as involving cognitive or physical engagement—like gaming or homework activities—while passive screen time entails low levels of interaction and intellectual involvement. Similarly, the American Academy of Child and Adolescent Psychiatry recommends engaging with children about what they watch, fostering opportunities for social, educational, and creative screen time. Unfortunately, these insights have not been fully embraced in public or political dialogues.

While encouraging intentional choices regarding children’s screen content, I do not imply that individual responsibility is the sole solution. We are experiencing a digital public health crisis, as highlighted by General Vivek Murthy, the U.S. Surgeon General, who noted that social media can heighten the risks of anxiety and depression in youth. There is an urgent need for comprehensive policies that tackle the technological and economic frameworks underpinning these platforms. This is where Kyle should focus his efforts.

Meanwhile, the proposals from Kyle should not rely on outdated public guidance. They must be rooted in a nuanced understanding of varied screen use, addressing both physical and mental health concerns while tackling systemic issues in digital platform design. Crucially, they must consider not just the quantity, but also the quality of children’s digital engagement.

Until such changes are made, the onus of responsibility falls on individuals—particularly parents—to ensure their children are learning, engaging, proactive, and safe during screen time. I know this may feel overwhelming. To help, here are some strategies to implement with my kids this summer.

  • For younger children, limited screen time is generally preferable. If screens are used, I recommend watching live TV on platforms like CBeebies or CBBC, emphasizing quality engagement.

  • Prioritize content that encourages active participation over passive consumption. Content that fosters creativity and dialogue supports cognitive engagement and enhances communication skills, often leading to meaningful discussions.

  • Begin instilling critical thinking about digital content early. Use tools like SightEngine to analyze images, helping to distinguish between real and potentially misleading content. This sparks conversation about online misinformation.

  • Engage older children in discussions about a healthy digital diet. Together, commit to actively seeking out positive content for 30 minutes each week, deliberately avoiding uninteresting or negatively skewed material.

Forests with Healthy Wildlife Populations Store Four Times More Carbon

Capuchin Monkeys and Their Role in Seed Dispersal in Tropical Forests

Tropical ecosystems, rich in animal biodiversity that aids in seed dispersal, can sequester carbon at rates up to four times higher than fragmented forests lacking these animals or where their movements are limited.

“This underscores the connection between the loss of animal biodiversity and the processes that intensify climate change,” explains Evan Fricke from the Massachusetts Institute of Technology. “We’ve lost the potential for tropical forest regeneration.”

While animals only store a fraction of the carbon in their environment, their activities significantly influence ecosystem carbon dynamics. Notably, species such as monkeys, birds, and rodents play a crucial role in dispersing a wide variety of seeds.

Fricke mentions that “linking this to a prolonged process like carbon capture across landscapes proved quite challenging.”

Fricke and his team examined over 3,000 plots in tropical forests where trees are returning and successfully reabsorbing carbon following disturbances. They then assessed the degree of movement and diversity disruption of seed-dispersing animals in each plot, with findings influenced by forest fragmentation and data from monitored animals.

They discovered that increased disruption in seed disperser movement correlated with lower rates of carbon accumulation. The forests with the most disturbed animal behaviors grew four times faster than those with minimal disruption.

On average, disturbances in animal diversity and movement patterns that disperse seeds halved the carbon accumulation potential of affected plots. This indicates that such disruptions had a more detrimental impact than other factors inhibiting tree regrowth, such as fires and livestock grazing.

In contrast, forests experiencing the least disruption sequestered carbon more rapidly than monoculture wood farms. “Natural growth enhanced by animal activity presents a cost-effective and biodiversity-friendly recovery method,” states Fricke.

Earlier ecological models indicated that seed dispersers might significantly influence carbon storage; however, this study further elucidates the critical role these animals play, according to Oswald Schmitz from Yale University. “It highlights their importance now and into the future.”

A Healthy Baby Conceived with Three DNA Sources to Combat Hereditary Diseases

Posted on by
Reply

LONDON – Eight healthy babies have been born in the UK, aided by experimental techniques designed to prevent mothers from transmitting severe rare diseases to their offspring through DNA, researchers have announced.

The majority of DNA resides within the nuclei of our cells and is inherited from both our mothers and fathers—essentially, it shapes who we are. However, mitochondria, the cell’s energy-producing structures, also contain DNA outside the nucleus. Mutations in this mitochondrial DNA can lead to various illnesses in children, resulting in symptoms like muscle weakness, seizures, developmental delays, major organ failure, and even death.

In vitro fertilization (IVF) testing typically helps identify these mutations, although there are instances where this is not evident.

Researchers have pioneered methods to circumvent these issues by employing healthy mitochondria from donor eggs. They reported their findings in 2023 in an article detailing the birth of the first babies born using this technique, which involves extracting genetic material from the mother’s eggs or embryos and transferring it to a donor egg or embryo possessing healthy mitochondria, while discarding the bulk of its original DNA.

Dr. Zev Williams, head of the Fertility Center at Columbia University and not involved in this study, stated that this research “marks a significant milestone.” He believes that broadening reproductive choices will allow more couples to achieve a safe and healthy pregnancy.

This method results in an embryo containing DNA from the mother, the father, and the donor’s mitochondria—an approach that became legally viable in the UK after law changes in 2016. Similar procedures are also permitted in Australia, though they remain banned in many countries, including the US.

Experts from Newcastle University in the UK and Monash University in Australia reported in the New England Journal of Medicine that they successfully implemented these new methods for fertilizing embryos from 22 patients, with one woman still pregnant.

One of the eight babies born exhibited unexpectedly high levels of abnormal mitochondria, according to Robin Lovell-Badge, a stem cell and developmental genetics scientist at the Francis Crick Institute, who was not involved in the research. While these levels are not currently deemed harmful, monitoring is required as the baby grows.

Andy Greenfield, a reproductive medicine expert at Oxford University not associated with the research, emphasized its significance, noting that mitochondrial replacement techniques are primarily used in other settings aimed at avoiding genetic illnesses, like early-stage embryo testing.

“This technique was certified a decade ago, so we have all been anticipating this report,” he shared with NBC News via email. “Fortunately, the children appear to be healthy.”

Long-term follow-up with these children is essential as keeping them healthy is a priority, he emphasized.

Lovell-Badge noted that the donor DNA’s contribution is minimal, asserting that the child will not exhibit characteristics from the women who provided the healthy mitochondria. The donor genetic material constitutes less than 1% of the DNA in babies conceived using this technology.

“In comparison, if you received a bone marrow transplant from a donor, you would possess significantly more DNA from other individuals,” he explained.

In the UK, all couples seeking childbirth via donated mitochondria must obtain approval from the national fertility authority.

Concerns have been raised by critics, who warn that the long-term effects of such innovative techniques on future generations remain uncertain.

“At this time, clinical application in the US is not allowed, mainly due to regulatory restrictions regarding genetic modifications to embryos,” Dr. Williams from Columbia said via email. “Whether this situation will evolve remains unclear and is subject to ongoing scientific, ethical, and policy discussions.”

For almost ten years, Congress has included provisions in the annual funding bill that prevent the FDA from accepting applications related to clinical research protocols involving the intentional creation or modification of human embryos to incorporate genetic alterations.

However, in jurisdictions where such methods are allowed, advocates argue they can offer a promising option for some families.

Liz Curtis, whose daughter Lily passed away from mitochondrial disease in 2006, is collaborating with other families affected by these disorders. She expressed the devastation of receiving a diagnosis indicating that death was inevitable for an infant without intervention.

Curtis reflected on how the diagnosis “turned our world upside down, and yet there was minimal discussion about it, what it entailed, and how it would affect Lily.” Following this experience, she founded the Lily Foundation in her daughter’s honor to raise awareness and support regarding the disease, alongside her latest initiatives at Newcastle University.

“This development is incredibly exciting for families who have little hope for a positive outcome,” Curtis remarked.

The UK fertility authority, which oversees human fertilization and embryology, endorsed the findings, noting that this technique might only be accessible to individuals with a high risk of transmitting disease to their children.

As of this month, 35 patients have been approved to undergo the procedure.

Study Reveals Potential Weight Gain from Certain ‘Healthy Fats’

Posted on by
Reply

Recent studies indicate that the fats found in olive oil may contribute to weight gain more significantly than fats from other sources.

A recent report revealed that oleic acid, the primary fatty component in olive oil, can stimulate the formation of new fat cells.

Oleic acid is a type of monosaturated fat, often referred to as omega-9. While olive oil is the main source of oleic acid, this fatty acid is also present in other oils, such as canola and sunflower oil.

“You can think of fat cells as the army,” stated the study’s co-author, Dr. Michael Rudolph, Assistant Professor of Biochemistry and Physiology at the University of Oklahoma. “Dried oleic acid initially boosts the number of ‘fat cell soldiers’ in the army, enhancing the capacity to store surplus dietary nutrients.”

“If excess nutrients surpass the number of fat cells over time, it can lead to obesity, and if left unaddressed, may result in cardiovascular disease or diabetes.”

Olive oil is a key component of the Mediterranean diet and is renowned for promoting longevity, healthy aging, as well as optimal brain, heart, and metabolic health – Credit: Elena Noviero via Getty

Researchers from the University of Oklahoma, Yale University, and New York conducted a study where mice were fed a variety of high-fat diets that included coconut oil, peanut oil, milk, lard, and soy oils.

They found that elevated levels of oleic acid influenced the activity of two proteins, AKT2 and LXR, leading to an accelerated growth of progenitor cells that develop into new adipocytes. This effect was not observed with other types of fats.

Nevertheless, Dr. Rudolph emphasized that completely eliminating olive oil is not the answer.

“The key takeaway is moderation and diversifying fat sources,” he advised. “While a balanced intake of oleic acid can be beneficial, excessive and prolonged consumption may pose risks. For individuals at risk for heart disease, high oleic acid levels could be unfavorable.”

In moderation, oleic acid is linked with numerous health benefits. Previous studies have shown that olive oil consumption is associated with longer lifespans, healthy aging, reduced inflammation, and a decreased risk of obesity and heart disease.

It’s important to note that since this study was conducted exclusively on mice, its findings may not directly apply to humans.

6 “Healthy” Foods You Might Not Realize Are Highly Processed

Posted on by
Reply

Pre-packaged foods like pasta and rice are staples in a balanced diet, but items like potato chips and sugary snacks are clearly less healthy. For many processed packaged foods, label claims can muddle the lines between what is genuinely nutritious and what isn’t.

Recent studies indicate that ultra-processed foods can elevate the risk of over 30 health issues, including cardiovascular and metabolic diseases, as well as mental health concerns. Therefore, the degree of processing and its effects on our bodies should be increasingly scrutinized.

While every food contributes to a healthy, balanced diet, not all foods hold the same nutritional value. It’s vital to approach your nutritional plan without solely relying on the claims made on food labels; consider how these foods fit into the broader context of your life and your goals, taking into account your unique health needs, financial situation, work commitments, and other life pressures.

Additionally, there’s no need to panic over headlines that warn of a “50% increased risk” of a disease from certain foods. While this sounds alarming, such statistics represent relative risks for the general population, not the individual.

This implies that these figures are not absolute; they depend on variables like the quantity of food consumed, frequency of intake, dietary diversity, and overall health risks.

Nutrition doesn’t exist in isolation, but understanding evidence, avoiding exaggerations, and considering context can help us make healthier choices. Below are some commonly misunderstood supermarket products.

“Premium” Ready Meals

Prepared meals such as lasagna, shepherd’s pie, and curry often labeled as “Finest” or “Best” are marketed as convenient shortcuts to balanced nutrition. Although the ingredient lists may seem appealing, including pasta, meat, cheese, and spices, cooking these dishes at home from scratch remains a more nutritious choice.

Ready meals frequently contain preservatives and stabilizers, often being overly salty for preservation, safety, and enhanced flavor.

Manufacturers that use fewer ingredients typically do so to cut costs, resulting in dishes that are often unbalanced and lacking in vegetables.

Cooking at home offers the added advantage of incorporating more vegetables and whole grains into your meals. Consider adding veggies to your ready-made meals for better nutrition without sacrificing convenience.

Plant-Based “Milk”

Plant-based milk alternatives are marketed as “healthier” substitutes for traditional dairy products. However, they are not direct nutritional equivalents.

Dairy products undergo minimal processing, while plant-based alternatives are often highly processed, involving heating, juicing, and extracting, with nutrients like calcium added later but prone to settling at the bottom. If the carton isn’t shaken well, these nutrients often go undetected.

The health benefits of plant-based milk alternatives are still up for debate, as while they are great for those who cannot or choose not to consume traditional dairy, long-term consumption effects haven’t been thoroughly investigated.

Meat Alternatives

Much like plant-based milk, meat substitutes derive their health halo from being “plant-based.” However, it’s worth noting that chips, candy, and beverages can also be made from plants. The true benefit lies in consuming whole foods rather than heavily processed plant-based ingredients.

Reducing meat consumption, particularly processed varieties, is associated with improved overall health, but replacing one unhealthy component with another doesn’t necessarily yield health benefits.

Meal Replacement Drinks

These beverages often claim to deliver complete nutrition within calorie-controlled portions while requiring minimal preparation effort. While they might be useful in specific situations, such as illness or injury, they come with caveats.

While these drinks contain essential nutrients, they often lack natural food’s vital “biological activity,” compounds that promote health. Also, relying heavily on these formulations reduces dietary diversity, key for spreading risk and enjoyment in one’s diet, making it crucial to seek professional guidance for balanced nutrition.

Breakfast Cereals

Breakfast cereals can vary widely in nutrient content. Some are minimally processed and low in sugar, such as oats, while others are sugary and closely resemble dessert items.

Research has linked the consumption of breakfast cereals to improved overall nutrition. Context is vital when evaluating their role in your diet.

Granola/Protein Bars

This category features a wide range of products. Some bars are heavily processed, high in salt, sugar, and additives, yet context plays a significant role. Replacing whole foods with these bars may not promote health, but if you’re swapping out less healthy snacks, they can present some benefits. For many, the convenience, shelf-stability, and predictability of these bars can be advantageous, though they’re likely not a nutritious daily staple for most people.

Orca successfully delivers healthy calf after carrying deceased newborn over 1,000 miles

Posted on by
Reply

The orca who captured hearts worldwide in 2018 by refusing to let go of her deceased calf has now welcomed her second baby in the last four years.

The Whale Research Center has confirmed that their team has started monitoring the new baby girl on Monday, giving her the alphanumeric name “J61.” They are closely monitoring and observing the calf’s well-being.

The mother, known as Tahlequah with the designation number J35, is an experienced mother. The center is concerned about the health of both J61 and her mother during this critical period.

The early years are especially risky for newborn calves, with high mortality rates in the first year. The Center for Whale Research expressed their hope that J35 will be able to keep J61 safe through this challenging time.

Tahlequah made headlines globally in 2018 when she carried her deceased calf for 17 days, moving people around the world with her display of grief. Her actions prompted Washington State Governor Jay Inslee to establish the Southern Resident Killer Whale Task Force for conservation efforts.

J61 is Tahlequah’s third surviving calf, following J47 or “Notch” born in 2010 and J57 or “Phoenix” born in 2020. They belong to the J pod of killer whales, residing in the coastal waters between Washington state and Vancouver Island, British Columbia.

The J-Pod is one of three pods of Southern Resident killer whales, totaling about 73 orcas across the pods. Conservation groups are working to protect and restore the declining population of these majestic creatures.

Threats to killer whales include entanglement in fishing nets, food scarcity, human interference, and environmental pollution. The declining population highlights the urgent need for conservation efforts to protect these endangered animals.

Contaminants in the water pose a significant threat to orcas, with industrial chemicals accumulating in the food chain and affecting the health of the whales. Female southern whales and their offspring are particularly vulnerable to these pollutants.

NOAA’s 2022 pod health assessment raises concerns about the impact of contaminants on the Southern Resident killer whale population, emphasizing the need for immediate action to protect these magnificent creatures.

Maintain Your Streak: Harnessing Daily Habits for a Healthy Life or Destructive Obsession

aAnyone who saw the run that Tom Vickery uploaded to the sports-tracking app Strava on February 18th of last year might have been a little confused. The 30-minute sprint appeared to be taking place in the middle of the Channel, not far from Guernsey, toward the west coast of France. And, oddly enough, the run was in a straight line, as measured by a ruler, and was shown on Vickery’s public profile as a one-inch, unbending orange line within a blue swath of the app’s virtual ocean. Oh, and it was on world-record-breaking pace.

Of course, it probably came as no surprise to anyone who knows Vickery. The 38-year-old triathlon coach from Cambridge was on holiday to Bilbao for a two-day ferry trip, and this fairly fast jog was just one of almost four years of daily runs he had been recording on Strava at the time. Determined not to break the record on board, Vickery got up at 5am and spent his allotted 30 minutes sprinting up and down the deck. As the boat slid through the water, he appeared to be running faster than any long-distance runner in the world.

This is just one example of the lengths some people will go to to maintain a “streak.” A streak is something (actually anything) that continues uninterrupted over a period of time. It’s a form of gamification: the process of adding game-like elements to a task to make it more engaging. Perhaps the most famous “streak holder” is British runner Ron Hill, who ran every day for 52 years and 39 days (or 19,032 consecutive days), even going for a jog the day after breaking his sternum in a car accident in 1993.

Hill, a scientist, used to keep a diary of his runs, but more recently, advances in technology have made it possible to keep track of streaks in a more streamlined and user-friendly way. For example, on Snapchat, the word “streak” is part of the lexicon. A “snap streak” is the number of consecutive days that a user sends “snaps,” either photos or messages, to other users. To maintain a snap streak, a user must send a snap within a 24-hour period or the streak ends.

6 “Healthy” Foods That Are Actually Ultra-Processed

Posted on by
Reply

Many of us include staple foods like pasta and rice in our diets for balance, while avoiding unhealthy options like potato chips and sugary snacks. However, determining the healthiness of processed and packaged foods based on their labels can be challenging.

A recent study found that ultra-processed foods increase the risk of over 30 health problems, highlighting the importance of considering the level of processing and its impact on our health.

It’s essential to understand that all foods can have a place in a healthy diet, but not all are equally nutritious. Rather than relying solely on food labels, it’s crucial to consider how these foods fit into your overall lifestyle and goals, taking into account factors like health, finances, work, and time constraints.

When faced with headlines about certain foods increasing the risk of disease by a certain percentage, it’s important to remember that these numbers represent relative risks in the population, not individual risks. Factors like the amount and frequency of consumption, overall diet, and disease likelihood all play a role in determining actual risk.

Nutrition is not isolated but influenced by evidence, hype, and context when making healthy choices. Here are some common supermarket products that are often misunderstood:

“Premium” Instant Meals

Prepackaged meals marketed as premium options may seem convenient and tasty, but they often contain added preservatives, stabilizers, and high levels of salt. Cooking from scratch at home is typically a more nutritionally sound choice.

When preparing meals at home, there’s more opportunity to add vegetables and whole grains for a balanced diet, something often lacking in ready-made options.

Plant Milk

Plant-based milks marketed as alternatives to dairy products vary in nutritional value, and they can be highly processed. While they can be useful for those who cannot or choose not to consume traditional milk, their long-term health effects are not well-studied compared to whole plant foods.

Meat Substitute

Similarly, meat substitutes may be processed and lack the full benefits of whole plant foods. Replacing meat in the diet can be beneficial for health, but choosing minimally processed plant-based options is key.

Meal Replacement Drinks

While meal replacement drinks can offer complete nutrition and convenience, they lack the bioactive substances found in whole foods. It’s important to incorporate a variety of foods into your diet and seek professional advice if relying heavily on meal replacements.

Breakfast Cereal

Breakfast cereals range in nutritional quality, with some being minimally processed and others high in sugar. Studies suggest that consuming breakfast cereal can improve overall nutrition, but the context of an entire diet is crucial.

Granola/Protein Bars

Bars can be convenient but are often processed and may contain excessive salt, sugar, and additives. While they can offer benefits over unhealthy snacks, they should not replace whole foods in the diet.

Despite its wealth, why is the United States still not as healthy as it should be?

People in the United States are watching with increasing caution. aging progresses Among Washington, DC's elected leaders, the two current leading candidates for the 2024 presidential election are currently 81 and 77 years old. But the longevity of the leadership stands in sharp contrast to the reality in other parts of the country. Americans are literally dying of disease.

Ten years ago, I led a study. National Academy of Sciences (NAS) This paper is the first to document that the United States has a disadvantage in health and survival among high-income countries.our report The United States has the lowest life expectancy of any country and has been shown to have high rates of morbidity and mortality from dozens of causes. This health and survival deficit has been growing for more than 40 years, affecting men and women, young and old, rich and poor, and of all races and ethnicities.

Average life

Meanwhile, other the study This trend has been confirmed as the life and death situation worsens. Life expectancy in the U.S., after plateauing for several years, had declined for three consecutive years before the global pandemic hit. What followed was devastating. COVID-19 has killed more than 1 million people in the United States and cut life expectancy by an additional two years, twice as much for Hispanics, Blacks, and Native Americans. This was the steepest decline in life expectancy since then. Second World War and nothing comparable happened other wealthy countries.

During the pandemic, Eight Among the 10 main causes of death, the following also increased: maternal and children and youth death. Given these harsh realities, the pressing question is why are Americans so unwell?in new scientist Ten years ago, I realized the reason was simple, yet deceptively complex. That's pretty much it.

Even a casual look at life in America today reveals an incredible situation.The country is entering its third decade of national deaths. opioid epidemic – unleashed by pharmaceutical industry – 110,000 lives were claimed in 2022 alone. And along with drugs, there are also bullets. In 2020 and 2021, Guns killed more American children It is more common among people between the ages of 1 and 17 to die from any other cause.

However, the United States is well known for being one of the most complex and fragmented nations. expensive medical system world.largely 30 million the american people No health insuranceAnd for millions of others, quality, affordable, and accessible health care is simply out of reach or effectively not available.

The final feature of the U.S. situation is one of its most important factors: systemic racism and the injustices that accompany it. In 2021, Average life For Asian Americans it was 84 years, for Hispanic Americans it was 78 years, for white Americans it was 77 years, for black Americans it was 72 years, and for Native Americans it was 67 years. native community They have long experienced some of the most severe health inequalities in this country, a direct reflection of the cumulative violence, trauma, and injustice inflicted on them over generations. . It is difficult to overstate the impact of racism in the United States today.

If health is wealth, then the United States is far from being the rich and powerful country many imagine.other countries will do well too do not have They will follow the Americans down this deadly path. And the United States should consider the many ways other industrialized democracies are achieving far better and more equitable health outcomes at far lower costs.
