摘要
Bone mineral density (BMD) was measured at the middle phalange of the non-dominant hand by dual x-ray absorptiometry in a random sample of 123 women aged 19 to 63 years. Monthly intake of foods with high Oxygen Radical Absorbance Capacity (ORAC) was obtained using a Food Frequency Questionnaire (FFQ), ORAC scores were calculated, and lifestyle factors were used as, confounding variables.. After adjusting for age, supplement use, HRT status,. physical activity, calcium intake; and ORAL intake,. BMD was not predicted by ORAC. We conclude that more research is needed to measure ORAL for all free radicals in all commonly consumed fruits, vegetables, and teas in order to, improve the usefulness of the FFQ in calculating approximate dietary. ORAC. At this time, the potential of ORAC as a reliable predictor of health remains largely unknown, however, using currently available ORAC information, it cannot be considered a predictor of BMD.
