摘要：The relationship of dietary fat to atherosclerosis is an area of continuing research. In order to establish if there is a seasonal variation in lipid status, we determined the dietary intake of lipids as well as their serum levels in 65 (33 males and 32 females) free-living subjects (67-75 years) in winter and summer. Both fat and cholesterol intakes were generally higher for men than women, but no seasonal differences were found for either gender. Nor in either sex was there any significant association of dietary fat intake (polyunsaturated/saturated fatty acid ratio) with either triglycerides or cholesterol levels in serum. Dietary unsaturated fatty acid but not the cholesterol intake appeared to have a marginal effect on serum cholesterol. According to the Canadian Society of Clinical Chemists reference standards for total serum cholesterol, 18% of the men and 41% of the women in this study population would be classified as high-risk (>5.2mmol/liter). HDL cholesterol, however, was consistently higher in the women. Total fat intake contributed 34% of total energy for both genders regardless of the season.
