The term sarcopenia refers to the loss of muscle mass that occurs with ageing. On the basis of study results showing that muscle mass is only moderately related to functional outcomes, international working groups have proposed that loss of muscle strength or physical function should also...

This prospective cohort study in 4203 older men aged 70-88 years in Perth, Western Australia showed an inverse association between plasma 25(OH)D levels and frailty, as well as all-cause mortality, over a period up to 9 years. Context and objective Hypovitaminosis D and frailty are common...

High-protein (>30% of energy from protein or >1.2 g/kg/day) and moderately high-protein (22% to 29% of energy from protein or 1.0 to 1.2 g/kg/day) diets are popular for weight loss, but the effect of dietary protein on bone during weight loss is not well understood. Protein may help...

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...

Choline is a dietary component essential for normal function of all cells. It, or its metabolites, assures the structural integrity and signaling functions of cell membranes; it is the major source of methyl-groups in the diet (one of choline's metabolites, betaine, participates in the...

Abstract Bed rest studies revealing a “horrifying” loss of muscle mass in older people after just a few days of inactivity should serve as a wake-up call for industry to put tackling sarcopenia higher up the priority list, scientists have argued. Speaking at the IFT show earlier this month...
