Instagram’s Ongoing Commitment to Youth Safety: Will the New “PG-13” Guidelines Make a Difference?

For months, Instagram has faced challenges in persuading parents, advocates, and officials that it is a safe environment for children, despite increasing evidence indicating otherwise. Now, the platform is rolling out another safety feature intended to protect teens. Yet, given its track record, parents remain skeptical.

Beginning this week, all users under 18 will automatically be categorized for ages 13+ and their feeds will be restricted to content suitable for the U.S. PG-13 movie rating.

However, Instagram’s previous unfulfilled commitments make this latest content restriction feel like mere window dressing—an illusion of action without genuine effectiveness.

The company has accrued substantial profits while advocacy groups have long cautioned against exposing minors to inappropriate content and individuals. $100 billion annually is what it reports in profits. Meta’s own estimates suggest that about 100,000 children using Facebook and Instagram face online sexual harassment daily. This is concerning, especially considering that as of July 2020, internal communications revealed that the measures to prevent child grooming on the platform were, at best, “between zero and negligible.” The lawsuit in New Mexico claims that Meta’s social networks, including Instagram, have essentially become a haven for child predators. (Meta refutes these core allegations, claiming the lawsuit is ‘unfair’.)

Last year, the firm finally enacted mandatory Instagram accounts for teenagers. However, a recent study led by a whistleblower revealed that 64% of the new safety features designed for teens were ineffective.

Research indicates that 47% of young teen users on Instagram encounter unsafe content, and 37% of users aged 13 to 15 receive at least one unsafe piece of content or unwanted message weekly. This includes “approximately 1 in 7 users viewing self-harm content, unwanted sexual content, discriminatory content, or substance-related content every week.”

“These failures showcase a corporate culture at Meta that prioritizes engagement and profit over safety,” stated Andy Burrows, CEO of the UK’s Molly Rose Foundation, which advocates for stronger online safety legislation, as part of the investigative team. BBC reported. A spokesperson for Meta countered that the study “misrepresents our commitment to empowering parents and protecting youth, and mischaracterizes the functionality of our safety tools and their use by millions of parents and youth.”

Concurrently, measures introduced last year followed a significant moment for Meta’s public perception. In January 2024, the leaders of the world’s major social media firms were summoned to the U.S. Senate to discuss their security policies. Meta CEO Mark Zuckerberg issued an apology to parents whose children allegedly endured harm from social media.

Despite Instagram’s lengthy struggle to address these concerns, it appears to continually place children at risk, only to issue apologies afterward. On Monday, Reuters reported that it has been found in company-specific research that teens who frequently felt negative about their bodies on Instagram encountered three times more “eating disorder-related content” than their peers. Alarmingly, technology companies and social media platforms have become so entrenched in everyday life that it’s nearly impossible to engage with society without them, particularly for children.

So, what is the resolution? Primarily, we must acknowledge online spaces as extensions of the real world, rather than merely digital counterparts. Social media platforms replicate real-life violence and can cause other tangible harms, putting children at a higher risk.

It’s essential for lawmakers to require these companies to incorporate safety measures into their design processes rather than treating them as an afterthought. Equally vital is for parents to educate their children on online safety, just as they would about physical safety in public.

The technology developed by these profit-driven companies is pervasive. If we cannot rely on them to safeguard our most vulnerable users, it falls upon us to ensure our own protection.

Nordic Dietary Guidelines for Promoting Longevity

The Nordic Nutrition Recommendations 2023 emphasize a decrease in meat consumption while encouraging an increase in the intake of vegetables, fruits, berries, grains, nuts, and pulses. Research from Aarhus University, Aarhus University Hospital, Karolinska Institutet, and the University of Copenhagen indicates that adherence to these guidelines correlates with a reduction in mortality rates.

Diets significantly contribute to climate change, accounting for approximately 30% of global greenhouse gas emissions stemming from food production and consumption.

The Nordic Nutrition Recommendations 2023 aim to balance human health with sustainability.

“Our research shows that middle-aged Swedish men and women who adhere to these guidelines enjoy a 23% reduction in mortality rates compared to those who do not, factoring in education, income, and physical activity,” stated Anne Baku Molch, a Ph.D. student at Aarhus University.

“Findings indicate a decline in mortality rates from cancer and cardiovascular diseases among individuals who strictly follow these guidelines.”

This study analyzed data from over 76,000 Swedish men and women through two large population studies: the Swedish mammography cohort and the Swedish male cohort.

Since 1997, these participants have documented their dietary and lifestyle habits, establishing a solid foundation for investigating the relationship between diet and health.

“The implications of these findings hold significance for both human and planetary health,” commented Dr. Christina Derm from Aarhus University.

“Given that national dietary guidelines are rooted in Nordic nutrition recommendations, our findings are applicable across Scandinavian and Baltic nations.”

“We demonstrate that adherence to the entire set of guidelines contributes positively to public health.”

“Our research extends further; as the guidelines account for both nutritional value and environmental impacts, our study reveals that sustainable Scandinavian diets can enhance public health and positively influence climate, serving as a model for dietary sustainability in other regions globally.”

“This research confirms that following a Scandinavian diet can benefit both health and the climate.”

“However, we have yet to investigate the dietary impact on other health conditions, such as obesity, type 2 diabetes, cardiovascular disease, or cancer.”

“We aim to explore these areas further in future studies.”

Survey findings were published in the Journal of Nutrition.

Three Essential Guidelines for an Effective Post-Workout Diet

Are carbohydrates, proteins, and liquids the foundations of your post-exercise diet?

When it comes to exercise, I’m not particularly focused on enhancing my performance or optimizing my biology. My primary goal is simply to remain active. Consequently, I have not given much thought to my post-exercise nutrition. However, training for a half marathon has illustrated to me the significance of properly fueling my body, and that it doesn’t need to be complicated.

It’s essential to understand that your post-exercise nutritional requirements can differ based on several factors, including the type of exercise you engage in, your age, gender, genetics, and more. Nonetheless, an April review in Sports Medicine discovered compelling evidence regarding three key interventions that enhance muscle recovery and performance. I consider these as foundational elements of a post-exercise diet.

The first element is carbohydrates. During exercise, your body taps into energy stores found in the liver and muscles. Replenishing these stores is vital to prevent muscle breakdown and ensure adequate energy for your next workout. Carbohydrates serve as the most effective source of this energy because they are quickly converted into usable fuel.

The review suggests that after four hours of intense exertion, athletes should consume 1-1.2 grams of carbohydrates per kilogram of body weight per hour. While this guidance may be geared more toward athletes, it’s advisable for all adults to consider a carbohydrate-rich snack or meal post-exercise. Opt for options that include both glucose and fructose, as glucose helps restore muscle energy and replenishes liver stores. Fruits are perfect, as they provide both.

The second element is protein, which is crucial for muscle recovery. Combining protein with carbohydrates has been shown to enhance performance. A 2016 study involving eight athletes indicated that those who consumed both macronutrients within two hours after an intense cycling session could ride an average of 14 minutes longer in their subsequent workout compared to those who only ingested carbohydrates. The timing of protein intake matters less than the quantity consumed. Reviews in Sports Medicine recommend 20-40 grams of protein after exercise.

study involving 72 men (also published in 2016) demonstrated that oral supplement solutions, milk, and orange juice were found to be more hydrating than water due to their electrolyte content, which aids in hydration and retention. Beverages like tea, coffee, soft drinks, and even beer provided hydration levels similar to water. Though I’m not advocating for pints post-workout, if water isn’t appealing, choose something delicious that you enjoy.

I still prefer simplicity, but now I focus on these three core elements. My favorite choice is a smoothie made with frozen fruits, orange juice, and protein powder. Although it’s not perfectly optimized, it represents an improvement. And it always satisfies my cravings after a run.
