Age-related and disease-related muscle loss: the effect of diabetes, obesity, and other diseases
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...
Dietary cholesterol, heart disease risk and cognitive dissonance
In the 1960s, the thesis that dietary cholesterol contributes to blood cholesterol and heart disease risk was a rational conclusion based on the available science at that time. Fifty years later the research evidence no longer supports this hypothesis yet changing the dietary...
Low vitamin D status is an independent predictor of increased frailty and all-cause mortality in older men: the Health in Men study
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...
Diet-induced weight loss: the effect of dietary protein on bone
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...
Activation of central orexin/hypocretin neurons by dietary amino acids
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...
Lack of effect of cold water prawns on plasma cholesterol and lipoproteins in normo-lipidaemic men
Objective Dietary guidelines for the prevention of coronary heart disease (CHD) have restricted the intake of foods rich in dietary cholesterol, on the grounds that the dietary cholesterol will increase blood cholesterol. In the case of shellfish, this recommendation may limit the intake...
Consumption of one egg per day increases serum lutein and zeaxanthin concentrations in older adults without altering serum lipid and lipoprotein cholesterol concentrations
Lutein and zeaxanthin accumulate in the macular pigment of the retina, and are associated with a reduced incidence of macular degeneration. The objective of the study was to investigate the effect of consuming 1 egg/d for 5-wk on the serum concentrations of lutein, zeaxanthin, lipids and...
Effect of dietary cholesterol on plasma cholesterol concentration in subjects following reduced fat, high fibre diet
One hundred and sixty eight subjects participated in a randomised crossover study to determine whether halving or doubling the present dietary cholesterol intake from eggs had any influence on blood cholesterol concentration in people following current dietary recommendations. During the...
Essential amino acid and carbohydrate supplementation ameliorates muscle protein loss in humans during 28 days bedrest
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...
