Nutrient composition

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 lipoprotein cholesterol in individuals greater than 60 y of age.

The Nutrient Rich Foods Index helps to identify healthy, affordable foods

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.

Our aim was to identify healthy, affordable foods and food groups by using the NRF index and US Department of Agriculture (USDA) nutrient composition and food prices data sets.

Does dietary protein reduce hip fracture risk in elders? The Framingham osteoporosis study

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.

Studies of the association between dietary protein intake and hip fracture risk are conflicting. Therefore, we examined protein intake and hip fracture risk in a population-based group of elderly men and women.

Assessment of the UK iodine status: a National Survey

The UK population may now be iodine-deficient, warranting a full review and evidence-based recommendations to safeguard public health, according to new research.

Iodised salt has helped to reduce iodine deficiency globally, but is not currently used in the UK.

The findings, presented at the Society for Endocrinology annual conference, provide the only current data on the UK’s iodine status; demonstrating iodine-deficiency in a large sample of the population.
