A Stanford Medicine-led trial of identical twins comparing vegan and omnivore diets found that a vegan diet improves overall cardiovascular health.

Stanford Medicine researchers and their colleagues have identified simple food swaps that, if adopted universally, could reduce the nation’s food-related carbon footprint by more than a third. The changes are also more healthy.

Fat from olive oil and nuts boosts the numbers of two key cellular structures and protects membranes from damage, lengthening the lives of laboratory worms, Stanford Medicine-led study finds.

Cells in the adult liver were thought to divide rarely. But a study led by Stanford Medicine researchers found intermittent fasting causes rapid cell division.

In a trial of the two low-carb diets, both were similarly effective in controlling blood glucose. Keto’s more severe carb restrictions did not provide additional overall health benefits.

Stanford Medicine researchers and colleagues found that as nations industrialize, a species of bacteria critical in the early development of infant gut microbiomes fades away.

Muscle stem cells enter a deep resting state during fasting or when fed a high-fat ketogenic diet, a Stanford-led study finds. This promotes stem cell resilience but slows injury repair.

Researchers found that one fiber supplement seemed helpful while another appeared harmful — but study participants’ reactions varied.

About 1 in 3 American adults has insulin resistance, a silent time bomb that doubles their risk for serious depression, Stanford scientists have learned.

Stanford researchers discover that a 10-week diet high in fermented foods boosts microbiome diversity and improves immune responses.

Giving people information about animal welfare can motivate them to eat less meat, a meta-analysis of 100 studies has found.
