Nutrient composition

Choline is a required nutrient, and some humans deplete quickly when fed a low-choline diet, whereas others do not. Endogenous choline synthesis can spare some of the dietary requirement and requires one-carbon groups derived from folate metabolism. We examined whether major genetic...

Choline is a dietary component essential for normal function of all cells. In 1998 the National Academy of Sciences, USA, issued a report identifying choline as a required nutrient for humans and recommended daily intake amounts. In ongoing studies we are finding that men have a higher...

Background: Dietary protein intake may help to manage blood pressure (BP) and prevent complications associated with elevated BP. Objective: The objective of this study was to determine whether 4 wk of increased protein intake (∼25% compared with ∼15% of energy intake that isoenergetically...

Background Egg yolks can be a source of docosahexaenoic acid (DHA) and iron but are often associated with adverse consequences on plasma cholesterol. Objective Our goal was to investigate the effect of consumption of 4 egg yolks/wk on infant DHA status and hemoglobin, ferritin, and plasma...

Highlights Brain orexin/hypocretin cells are stimulated by dietary amino acids (AAs) AA sensing involves K-ATP channels and system-A transporters Nonessential AAs stimulate orexin/hypocretin cells more than essential AAs AA presence prevents glucose from blocking orexin/hypocretin cells...
