Abstract
This study examined how high-density lipoprotein-cholesterol (HDL-C) correlated with a 3-day food record of fat, protein, carbohydrate, and alcohol consumption in a group of 270 healthy subjects over age 60. HDL-C concentrations correlated with alcohol consumption (expressed as grams/day) (r = + .25, P less than .001), and inversely with total carbohydrate (r = - .18, P less than .01) and refined carbohydrate (r = - .17, P less than .01) ingestion (expressed as a percent of total caloric intake). Subjects consuming diets low in either total carbohydrate or refined carbohydrate had 10 to 20% higher HDL-C levels than did those consuming diets high in these food substances. The relationships between HDL-C levels and alcohol and carbohydrate ingestion were independent of other variables which correlated with HDL-C levels. Dietary fat (total fat, saturated fat, unsaturated fat, and cholesterol) did not correlate with HDL-C. LDL-cholesterol and triglyceride levels did not correlate with any dietary variable measured.
