Vitamins, lipids and lipoproteins in a healthy elderly population.
Vitamin status may be related to serum lipid-lipoprotein levels. We tested this hypothesis in a group of 270 healthy elderly men and women over 60 years of age. Vitamin status was determined from dietary intakes and biochemical analysis of plasma. Fasting lipid profile included triglycerides, total cholesterol, low-density lipoprotein-cholesterol (LDL-C), and high-density lipoprotein-cholesterol (HDL-C). Correlations have been adjusted by partial correlation for age, physical activity, body mass index, and alcohol consumption. Neither vitamin E intake nor ascorbic acid intake nor ascorbic acid plasma levels correlated with any lipids measured. HDL-C levels did not correlate with any vitamin parameters. In men, vitamin A blood levels correlated with LDL-C, triglyceride, and total cholesterol levels. In women, total cholesterol levels correlated inversely with thiamine and riboflavin blood status and with dietary intake of vitamins B6, D, and niacin. LDL-C plasma values were also inversely correlated with both intake and plasma vitamin D levels and intakes of riboflavin and vitamin B12 in women.
