An US randomized crossover study showed that chronic dietary red meat increases systemic trimethylamine N-oxide (TMAO) levels through enhanced dietary precursors, increased microbial trimethylamine (TMA)/TMAO production from carnitine, but not choline, and reduced renal TMAO excretion. Discontinuation of dietary red meat reduces plasma TMAO within 4 weeks. There were 113 healthy […]
A prospective global cohort study suggested that total sleep duration of 6–8 h per day is associated with the lowest risk of deaths and major cardiovascular events (MCEs). Daytime napping is associated with increased risks of MCEs and deaths in those with >6 h of nighttime sleep but not in those sleeping […]
The U.S. Food and Drug Administration (FDA) responded to a petition for a new qualified health claim for edible oils containing high levels of oleic acid, a monounsaturated fat that’s been shown to have cardiovascular benefits when it replaces heart-damaging saturated fat.

A nationwide, randomized, placebo-controlled trial revealed that daily supplementation with high-dose vitamin D or n-3 fatty acids for 5 years among initially healthy adults in the US did not reduce the incidence of cancer or the incidence of major cardiovascular events. The trial included 25,871 participants (5106 black, ages >/=50 […]
Two prospective cohort studies revealed that physical activity was associated with a lower risk of mortality both in the general population and in patients with stable coronary heart disease worldwide. The 1st study included 130 843 participants without pre-existing cardiovascular disease, and followed 6·9 years. Higher physical activity was associated with […]
