Components of fat and their relationship to total energy are described for 2,368 white male and 2,200 white female adults, aged 20-59 years, for whom 24-hour dietary recalls were completed between 1972 and 1975 in nine North American populations as a part of the Lipid Research Clinics (LRC) Program Prevalence Study. Men had higher absolute intakes of total fat and cholesterol than women, although both sexes consumed diets similar in relative composition of polyunsaturated, saturated, and monounsaturated fatty acids. Marked geographical differences in intakes of energy, total fat, and dietary cholesterol were observed. Compared with data from dietary surveys conducted in the 1960's the LRC data showed that consumption of cholesterol had decreased by the early 1970's, whereas consumption of polyunsaturated fatty acids appears to have increased, resulting in a higher ratio of polyunsaturated to saturated fatty acids. However, comparison of current dietary guidelines with these data, which are based on a single dietary recall, showed that few LRC participants met the recommendations of the Senate Select Committee on Nutrition and Human needs for dietary fat intake.
针对2368名年龄在20至59岁之间的成年白人男性和2200名成年白人女性，描述了脂肪成分及其与总能量的关系。作为脂质研究临床项目（LRC）患病率研究的一部分，1972年至1975年期间，在北美九个地区对这些对象完成了24小时饮食回顾调查。男性的总脂肪和胆固醇绝对摄入量高于女性，尽管两性摄入的饮食在多不饱和脂肪酸、饱和脂肪酸和单不饱和脂肪酸的相对组成上相似。观察到能量、总脂肪和膳食胆固醇摄入量存在显著的地域差异。与20世纪60年代进行的饮食调查数据相比，LRC数据显示，到20世纪70年代初，胆固醇的摄入量有所下降，而多不饱和脂肪酸的摄入量似乎有所增加，导致多不饱和脂肪酸与饱和脂肪酸的比例更高。然而，将当前的饮食指南与这些基于单次饮食回顾的数据进行比较后发现，很少有LRC参与者符合参议院营养与人类需求特别委员会对膳食脂肪摄入量的建议。
