膳食能量密度已被证明对短期食物摄入量有很大影响。然而，人们对其起源知之甚少。我们调查了遗传的影响，共享（家庭）环境，和个人环境对饮食能量密度和它的关系，以食物摄入量与I 10同卵和102异卵同性和5 - 3异卵混合性别的成年双胞胎对谁支付保持7天的食物摄入日记。根据日记报告，估计食物能量的总摄入量和膳食摄入量、摄入的大量营养素的量和膳食能量密度。线性结构模型被用来调查遗传和环境影响的性质和程度。分析显示，显着的遗传和个人的环境，但没有共享（家庭）的环境，饮食密度的影响。但是，没有遗传或家族的影响，对个人的反应，饮食密度。膳食能量密度似乎是影响能量平衡调节的遗传决定的生理、社会文化和心理过程中的另一个组成部分。(c)2005年爱思唯尔公司All rights reserved.
Dietary energy density has been shown to have large effects on short-term food intake. Little is known, however, about its origins. We investigated the influence of heredity, shared (familial) environment, and individual environment on dietary energy density and its relationship to food intake with I 10 identical and 102 fraternal same-sex and 5 3 fraternal mixed gender adult twin pairs who were paid to maintain 7-day food intake diaries. From the diary reports, the total and meal intakes of food energy, the amounts of the macronutrients ingested, and dietary energy density were estimated. Linear structural modeling was applied to investigate the nature and degree of genetic and environmental influences. The analysis revealed significant genetic and individual environmental, but not shared (familial) environmental, influences on the dietary densities of the reported diets. But, there was no genetic or familial influences on the responsiveness of the individual to dietary density. Dietary energy density appears to be another component in a package of genetically determined physiological, sociocultural, and psychological processes that influence the regulation of energy balance.
