As a part of a study of the dietary habits of monozygotic twins, a nutrition survey including a 24-hour dietary recall interview and a three-day dietary diary was conducted on the members of 15 male and 13 female pairs of identical Caucasian twins ranging from 25 to 61 years of age. In this study, overall mean caloric, protein, fat, and carbohydrate intake of males was significantly greater than females. Members of male twin pairs also tended to be more similar than female twins in mean intake of all major nutrient groups. In general, the observed differences in overall intake between males and females were maintained even after adjustment of body weight. Male twins were characterized by greater similarity in intake of sodium and potassium; however, there was no consistent difference in the degree of correlation in intakes of members of male and female twins for either iron, calcium or phosphorus.
作为一项关于同卵双胞胎饮食习惯研究的一部分，对15对年龄在25至61岁之间的白人男性同卵双胞胎和13对白人女性同卵双胞胎进行了一项营养调查，其中包括24小时饮食回顾访谈和为期三天的饮食日记。在这项研究中，男性的总体平均热量、蛋白质、脂肪和碳水化合物摄入量显著高于女性。男性双胞胎成员在所有主要营养素组的平均摄入量上也往往比女性双胞胎更为相似。总体而言，即使在调整体重后，男性和女性在总体摄入量上观察到的差异仍然存在。男性双胞胎的特点是钠和钾摄入量更为相似；然而，在铁、钙或磷的摄入量方面，男性和女性双胞胎成员的相关程度没有一致的差异。
