Health Benefits Vary Depending on Honey Type

As a passionate honey enthusiast, I relish the taste of honey in everything from buttery sourdough bread to refreshing smoothies and savory Asian stir-fries. I often justify my sweet indulgence by recalling its numerous health benefits. But how true are these claims?

Honey is widely recognized as a healthier alternative to refined white sugar. Its less processed nature results in a more stable blood sugar level. Honey, derived from plant nectar and enriched by bees, primarily consists of monosaccharides like glucose and fructose, along with trace sugars like trehalose, kojibiose, nigerose, melibiose, gentiobiose, and palatinose. However, the health benefits of honey largely depend on the sources of nectar collected by the bees.

One useful measure for comparing honey to other sugars is the glycemic index (GI), which indicates how quickly a food raises blood sugar levels. Refined white sugar has a GI score of approximately 65. In contrast, honey’s GI can vary significantly; for example, honey made from Sidr tree nectar in the Middle East boasts a GI of just 32, while Greek thyme honey reaches a GI of 85. Interested in comparing various honey types? Check out the University of Sydney’s extensive GI database for more information.

The variation in GI values can be attributed to the differing ratios of glucose and fructose in honey. Glucose raises blood sugar levels rapidly, whereas fructose does not. Unlike refined sugar, which contains a consistent ratio of glucose and fructose, honey’s composition can vary, impacting its glycemic response.

Additionally, honey contains components like phenolic acids and flavonoids that may slow glucose absorption in the intestines, thus contributing to lower GI values. These compounds are also believed to possess antioxidant properties that provide mild protection against ailments like cancer and heart disease—conditions often associated with oxidative stress. However, it’s essential to remember that fruits and vegetables are far superior sources of antioxidants as they are lower in sugar and calories.

Opting for raw honey, often available at local markets, is considered a healthier choice compared to mass-produced varieties, as it retains a higher concentration of beneficial phenolic acids and flavonoids. Raw honey is freshly harvested directly from the hive and minimally processed. Unlike raw milk, raw honey is generally safe to consume, although there are risks of contamination from Clostridium botulinum, a bacterium producing a potent neurotoxin. This toxin is particularly hazardous for infants under one year. Parents should avoid giving honey to infants, and it’s advisable to steer clear of Botox for little ones as well.

Mass-produced honey undergoes pasteurization to eliminate microorganisms, compromising some beneficial antioxidants in the process. Furthermore, cheaper honey products may be mixed with sugar syrup, which dilutes their natural properties. Some honey products even falsely claim to be natural aphrodisiacs, containing hidden drug ingredients like tadalafil, the active component in the erectile dysfunction medication Cialis.

A straightforward way to gauge the phenolic acids and flavonoids in honey is by examining its color. Darker honey typically indicates higher levels of these beneficial compounds. Personally, I enjoy purchasing rich, dark brown raw honey from a local beekeeper, which I find far superior in taste compared to supermarket varieties. His bees gather nectar from local eucalyptus trees, which likely contributes to its lower GI value based on tests conducted on other eucalyptus honeys.

Is Honey Effective for Hay Fever or Just a Myth?

While many believe that consuming locally produced honey may relieve hay fever, this idea is rooted more in folklore than in scientific fact. The premise is that honey contains trace amounts of local pollen that might help the immune system acclimatize to these allergens. However, hay fever is primarily triggered by pollen from trees that bees do not visit; these trees release airborne pollen that can irritate your nasal passages. In fact, hay fever is caused by such wind-dispersed pollen.

Nonetheless, honey does demonstrate potential benefits in soothing symptoms like a sore throat and cough, likely due to its pleasant consistency and natural antibacterial properties. A review of existing studies found that honey could alleviate cough symptoms in children and was comparable in effectiveness to over-the-counter cough syrups. Anyone who has tried a warm lemon-ginger tea with honey can attest to its comforting effects when feeling unwell.

Honey’s efficacy extends beyond soothing sore throats; it also plays a significant role in wound care. Medical-grade Manuka honey, which is recognized in countries like the UK, US, and Australia, is often used in ointments and dressings. This honey is made from the nectar of Manuka tea tree flowers and is sterilized to eliminate harmful microorganisms. It possesses high levels of an antibacterial compound called methylglyoxal, which is effective in preventing or treating wound infections. Studies highlight its healing properties.

However, it’s crucial to heed warnings about honey derived from rhododendron flowers, especially from certain species native to Nepal and Turkey. This type of honey can cause “mad honey disease,” leading to symptoms such as confusion, dizziness, and vomiting. Historically, it has even been weaponized; for instance, Mithridates VI Eupator used it strategically against Roman troops in 65 BC, luring them into confusion. Do you dare to wonder what happened next?

While honey may not alleviate my hay fever, I still enjoy it—after all, there’s no sweeter delight than the joy it brings me.

Ill chimpanzees search for different plants with medicinal qualities

Some plants that chimpanzees eat when they are sick or injured have been found to have medicinal properties, providing some of the strongest evidence yet that our close relatives self-medicate.

Although there have been reports for decades of chimpanzees using plants to self-medicate, it's difficult to pinpoint when wild animals get sick and what effect their diet may have.

Elodie Freyman Oxford University researchers tracked wild chimpanzees in Uganda's Budongo Forest, recording when they became ill and what they ate. By analysing feces for signs of intestinal parasites and examining urine samples for elevated levels of immune cells, the researchers identified chimpanzees with obvious wounds or intestinal infections.

An analysis of 53 plant extracts ingested by sick or injured chimpanzees found that 88 percent were effective against bacteria pathogenic to humans, including antibiotic-resistant strains like MRSA, and extracts from all species sampled had anti-inflammatory properties.

This systematic approach has allowed the researchers to identify and characterize more species used by chimpanzees than ever before. Kirsty Graham “It's a very impressive project,” said Robert Cole, a researcher at the University of St. Andrews in the UK who was not involved in the work.

Sick chimpanzees would leave the safety of their group to eat certain plants, often choosing plants that were rarely eaten in that area. The rarity of these events makes self-medicating behavior very difficult to observe, but at the same time, it is one of the strongest pieces of evidence that it is a targeted response to illness.

Chimps are typically hesitant to try unfamiliar foods that might be dangerous, Freiman says, so choosing to eat an unusual plant means they have a special reason to do so: “If they're sick, they're not going to stuff their mouths with things that might make them sicker,” she says.

But this doesn't capture everything that's going on, Graham says, because chimpanzee diets are still very diverse. Over generations, a chimpanzee community may be able to overcome this reluctance to new foods if chimpanzees learn from other animals which plants to eat. Simultaneous direct comparisons of the diets of sick and healthy chimpanzees might reveal whether these are active choices, Graham suggests.

Team Members Fabian Schultz Researchers at the Brandenburg University of Applied Sciences in Germany hope that by identifying active compounds in plant extracts, they might uncover promising drug candidates for humans. “What if we could save human lives by following the example of our animal companions?” he says.

In a report released earlier this year, an orangutan, another great ape, was spotted applying plant leaves directly to a wound in an apparent act of self-medication.
