The aim of this study is to investigate the effects of dietary fiber intake on serum lipid concentration in the aged. The amount of daily food intake for three consecutive days was measured and the serum levels of total-cholesterol (TC), triglyceride (TG), HDL-cholesterol (HDLC) were determined for 270 subjects (135 males and 135 females), 65 years and over, living in a local community. The LDL-cholesterol (LDLC) was calculated by (TC—HDLC)—TG×0.2.
Dietary fiber intake showed little difference by sex.
Dietary fiber intake had a significantly positive correlation with HDLG, the intake of carbohydrates and protein and total fat, but had a significantly negative correlation with LDLC, LDLC/HDLG.
Multiple regression analysis showed that dietary fiber intake had a statistically significant relationship with HDLG, LDLC/HDLG, and LDLC.
Since HDLC, known as an antiatherogenic, was related to the increase in the dietary fiber intake, and LDLC, known as an atherogenic, was related to its decrease, it was suggested that dietary fiber intake might have an important effect on the genesis and prevention of atherogenic diseases.
