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...
Background The range of protein intakes for optimizing bone health among premenopausal women is unclear. Protein is a major constituent of bone, but acidic amino acids may promote bone resorption. Objective The objective was to examine cross-sectional and longitudinal associations between...
Summary Association between dietary protein and fracture risk is unclear. We examined association between energy-adjusted protein intake and hip fracture risk in elders. The risk of hip fracture was reduced in upper quartiles of protein intake when compared with lowest quartile...
High-quality proteins make a valuable contribution to the synthesis and maintenance of muscle and indirectly to the regulation of blood glucose levels, thus contributing to power, strength, and energy. Eggs have traditionally been used as the standard of comparison for measuring protein...
Background The Nutrient Rich Foods (NRF) Index is a formal scoring system that ranks foods on the basis of their nutrient content. When used in conjunction with a food prices database, it can help identify foods that are both nutritious and affordable. Objective Our aim was to identify...
Choline is an essential nutrient required for methyl group metabolism, but its role in carcinogenesis and tumor progression is not well understood. By utilizing a population-based study of 1508 cases and 1556 controls, we investigated the associations of dietary intake of choline and two...
Age related macular degeneration (AMD) is the leading cause of severe visual loss in people aged over 50 in the developed world. Early AMD is characterised clinically by yellow deposits known as drusen and changes in pigmentation of the retina. Late AMD develops when there is an ingrowth...
