Objective: To test whether adding herbs and spices to school lunch vegetables increases selection and intake compared with lightly salted control versions among rural adolescents.
Design: This study compared intake of vegetables with herbs and spices with lightly salted controls (phase I) and tested whether 5 repeated exposures would increase students' intake of herb and spice seasoned vegetables (phase II).
Participants And Setting: A total of 600-700 students at a rural middle/high school (age 11-18 years).
Background: The role of body iron stores in free radical-induced peroxidation and cardiovascular disease risk has been debated, but controlled feeding studies using measurements of non-transferrin-bound iron (NTBI) and LDL oxidation have not been conducted.
Objective: We tested the hypothesis that NTBI and other measures of iron status do not affect oxidative susceptibility in healthy subjects with normal iron status.
Design: Plasma samples were analyzed from 77 healthy men and women aged 20-65 y who participated in 3 controlled feeding studies in which the type and amount of dietary fat were controlled.
