In a dietary study on a subsample (1,113 males and females, 15-64 years of age) of the Coronary Risk Factor Study (CORIS) population, dietitians used the 24-hour recall method by interview to quantify nutrient intake and energy distribution and to investigate the relationship between dietary variables and blood lipid values. Mean total fat intakes varied from 35% to 37% of daily energy intake for different age groups. Dietary polyunsaturated/saturated fatty acid ratios varied from 0.48 to 0.59. Cholesterol intakes ranged from 243 mg/d to 500 mg/d and when expressed per 4.2 MJ (1,000 kcal) were similar for males and females. The results of this intrapopulation cross-sectional study showed no significant relationship between dietary variables and total serum cholesterol and high-density lipoprotein cholesterol. However, the low percentage of respondents who met the prudent dietary guidelines add dietary risk factors to the already high prevalence of other major risk factors in this population.
在一项针对冠心病风险因素研究（CORIS）人群子样本（1113名15至64岁的男性和女性）的饮食研究中，营养师通过访谈采用24小时回忆法来量化营养摄入和能量分配，并研究饮食变量与血脂值之间的关系。不同年龄组的总脂肪平均摄入量占每日能量摄入的35%至37%。膳食多不饱和/饱和脂肪酸比值在0.48至0.59之间。胆固醇摄入量在243毫克/天至500毫克/天之间，按每4.2兆焦耳（1000千卡）计算时，男性和女性相似。这项人群内横断面研究的结果显示，饮食变量与总血清胆固醇和高密度脂蛋白胆固醇之间没有显著关系。然而，符合谨慎饮食指南的受访者比例较低，这给该人群中本就高发的其他主要风险因素又增添了饮食风险因素。
