Experiments in animals and observations in humans suggest that the amount of proline circulating in one’s plasma has a strong association with depression severity.

Researchers determine that a primate’s tooth root, and not just its crown, can yield reliable information about body size, but the relationship between root surface area and diet isn’t as clear.

He was among the first to identify lifestyle factors that contribute to cardiovascular disease.

Research in mice and flies suggests that bacteriophages, including those found in dairy foods, may have an influence on an animals’ ability to learn and remember information.

A study identifies a gene that appears to be partially responsible for the health effects of a limited diet.

Reconstructing the diet and microbiome of human ancestors shows an astonishingly rapid loss of microbiome diversity.

The unbalanced gut flora present in some people with autism is not a driver of the condition but rather a consequence of eating behaviors characteristic of the condition, a new study claims.

Pharoah’s work ended endemic cretinism in a remote region of Papua New Guinea and contributed to the understanding of myriad other perinatal health conditions.

A high-salt diet suppressed the growth of tumors in a mouse model of melanoma, apparently because of an interplay between the gut microbiome and natural killer cells.

A study suggests that mutations in the gene that encodes the T1R1/T1R3 taste receptor allowed primates that relied on insects for protein to transition to eating leaves and fruit.

Synthetic biologists introduced an engineered microbe that may lead to new treatment options for phenylketonuria.

Microscopic creatures called epibionts that live on sea turtles’ shells can help researchers understand their secretive lives.

Mice with low vitamin D had exaggerated craving for opioids and felt the drugs’ effects more strongly—results supported in part by human medical records—suggesting that supplements should be explored as treatments for opioid use disorders.

Mice and flies given the polyamine in their diet have increased brain cell metabolism and cognitive function, and epidemiological data hints at a similar benefit in humans.

A study shows gamma-delta T cells in mice respond to shifts in nutrients by changing the cellular composition of the intestinal epithelium.

The study of diet, long plagued by inaccuracies in self reports, is entering a new age of precision with the methods of metabolomics.

Nutrition researchers are beginning to use metabolomics to determine how healthy subjects’ diets are, and even to reveal specific properties of the foods they eat.

NASA’s vegetable production system, known as Veggie, may help pave the way for more sophisticated systems that could supplement astronauts’ diets during long trips to space.

Genetically engineered Drosophila withstand toxins common in monarch butterflies’ diet.

Some experts blame our modern, sugary diet, while others think that gut microbiome changes and sedentary lifestyles may play a role. Altogether, the causes are far from clear.
