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.

Choline in the diets of the US population: NHANES, 2003-3004

To estimate choline intakes of US subpopulations including children, men, women and pregnant women.

Choline is an essential nutrient which plays critical roles in brain development and homocysteine metabolism. Choline is widely distributed in foods; good sources include eggs, meats, cruciferous vegetables and legumes. The DRI for choline is expressed as Adequate Intake (AI).

Dietary intakes of choline in US infants, children and women

Choline, an essential nutrient, is present in human milk and important for brain function. Adequate intakes (AIs) for choline were established by the IOM in 1998, but nationally representative estimates of intake are limited.

To assess intakes and sources of choline in diets of US non-breastfed infants, children 1-12 yrs and women 18-45 yrs, using NHANES 1999-2004 data.

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.
