Perspectives on intake of calcium-rich foods among Asian, Hispanic, and white preadolescent and adolescent females.

Objective: Declining calcium intake among adolescents warrants attention. Our objective was to identify influences on adolescents' consumption of calcium-rich foods.

Estimates of the effects of folic-acid fortification and folic-acid bioavailability for women.

Objective: With the recent implementation of the folic-acid-fortification program, our objective was to estimate its benefits in adult women and account for the higher bioavailability of synthetic folic acid in fortification programs and supplements.

Methods: The study used a cross-sectional design. Dietary assessment data were collected with a quantitative food-frequency questionnaire, the Nutrition DISCovery program.

A quantitative assessment of plasma homocysteine as a risk factor for vascular disease. Probable benefits of increasing folic acid intakes.

Objectives: To determine the risk of elevated total homocysteine (tHcy) levels for arteriosclerotic vascular disease, estimate the reduction of tHcy by folic acid, and calculate the potential reduction of coronary artery disease (CAD) mortality by increasing folic acid intake.

Data Sources: MEDLINE search for meta-analysis of 27 studies relating homocysteine to arteriosclerotic vascular disease and 11 studies of folic acid effects on tHcy levels.

Study Selection And Data Extraction: Studies dealing with CAD, cerebrovascular disease, and peripheral arterial vascular disease were selected.
