[The relationship between dietary ascorbic acid intake and serum lipid concentration in the aged].
The aim of this study was to investigate the relationship between dietary ascorbic acid intake and serum lipid concentration in the aged. The amount of dairy food intake for three consecutive days were measured and the serum levels of total-cholesterol (TC), triglyceride (TG), HDL-cholesterol (HDLC) were determined 279 subjects (135 males and 135 females), 65 years and over living in one community. The LDL-cholesterol (LDLC) was calculated by (TC-HDLC)-TG x 0.2. Dietary ascorbic acid intake showed no significantly difference between males and females, but had a significantly positive correlation with HDLC, the intake of carbohydrates and protein and total fat. However it had a significantly negative correlation with LDLC and LDLC/HDLC. Multiple regression analysis showed that dietary ascorbic acid intake had a statistically significant relationship with HDLC, LDLC and LDLC/HDLC. Since HDLC, which is known to be an anti-atherogenic, was related to increase in the dietary ascorbic acid intake, and LDLC, which is known to be an atherogenic, was related to its decrease, it was suggested that dietary ascorbic acid intake might have an important effect on the genesis and prevention of atherogenic diseases.
