Abstract
Aging may modify both the availability of and needs for certain nutrients. Our study was done to assess the contribution of age alone to micronutrient levels in older volunteers (aged 60 or more). One hundred two healthy elderly white subjects, 63 women and 39 men, carefully screened by history or chart review, were studied in the fasting state. All were noninstitutionalized without serious chronic or acute illness; their diets were nutrionally adequate, containing more than two thirds of the recommended dietary allowance (RDA) for all nutrients, and no subject was taking more than twice the RDA of fat-soluble vitamins. These subjects had higher levels of plasma and red blood cell carnitine, and vitamins A, E, and C. They had lower levels of albumin, transferrin, and zinc than younger laboratory reference subjects. Retinol-binding protein, serum and red blood cells folate, and copper levels were not different. With increasing age, levels of transferrin and vitamins C and E fell; and all other measured micronutrient levels were similar. Albumin, vitamin C, and copper values were higher among elderly women, and plasma and red blood cell carnitine values and zinc levels were higher in elderly men. There was great variability in the micronutrient levels despite similar nutrient intakes.This publication has 5 references indexed in Scilit:
