A healthy diet is key to a healthy gut microbiome

A large-scale study analyzed the gut microbiomes of over 21,500 individuals and found that vegan diets had the healthiest microbiomes, followed by vegetarians and omnivores. The researchers discovered unique microbial signatures for each dietary pattern, with vegans having more beneficial bacteria associated with fiber fermentation.

Sweet tooth- Ethiopian wolves seen feeding on nectar

Researchers observe Ethiopian wolves foraging on nectar-rich flowers, exploiting a novel plant-pollinator interaction. This behavior is significant as it highlights the complexity of interactions between species in the highlands ecosystem, threatening these rare canines.

Increasing evidence that bears are not carnivores

Researchers have found that captive bears prefer a high-carbohydrate, low-protein diet, which is different from the typical high-protein diet they receive in zoos. This dietary preference is consistent with the bears' natural diet in the wild and may contribute to their shorter lifespan in captivity.

Gut microbiomes help bears with very different diets reach the same size

A recent study of Alaskan brown bears reveals that their gut microbiomes play a crucial role in supporting health and achieving comparable size despite eating vastly different diets. The research sheds light on the importance of diverse dietary niches for bears, which can help them extract nutrition from various food sources.

The world's largest omnivore is a fish

Researchers discovered that whale sharks eat a significant amount of plant material, including Sargassum seaweed. This challenges previous assumptions about their diet, revealing they are not just filter feeders on krill.

Humans disrupting 66 million-year-old feature of ecosystems

Some meat eaters disgusted by meat

A new study published in Appetite found that nearly 7% of meat eaters experience a strong disgust response to images of meat dishes, which could be leveraged to encourage reduced meat consumption. Researchers suggest harnessing this 'yuk factor' may be more effective than relying on willpower.

High dietary fiber intake linked to health promoting short chain fatty acids

Research published in Gut found that a high-fiber diet is associated with increased levels of health-promoting short-chain fatty acids, which may help reduce the risk of inflammatory diseases, diabetes, and cardiovascular disease. The study also showed that vegans and vegetarians had higher levels of these beneficial compounds.

Scientists trace evolutionary history of what mammals eat

Researchers traced the evolution of mammalian diets across all species, including omnivores, and found that while some groups maintained steady diets, others changed their feeding strategies over time. Today's omnivores originated from ancestors primarily eating plants or animals but not both.

New study traces the evolutionary history of what mammals eat

A new study has traced the evolutionary history of mammal diets, revealing that omnivores, including primates, bears, and dogs, came from ancestors that primarily ate plants. The study found that diet is linked to species diversification, with plant-eaters proliferating faster than meat-eaters.
