食物的能量密度（千卡/克）和份量（克）已被确定为可以调节能量摄入的食物的两个属性。最近的研究表明，当能量密度或食物份量增加时，能量摄入量就会增加。在一顿饭中，当这两个因素同时增加时，它们的作用是独立的，并且共同增加能量摄入。另一方面，降低第一道菜的能量密度，同时增加消耗量，会导致整顿饭的能量摄入量减少。这两个因素发挥影响的机制尚不清楚，但可能包括认知和口腔感觉因素以及与胃扩张和胃排空相关的生理控制。该研究领域的研究结果证明，能量密度和食物的份量是能量摄入的重要决定因素。食品供应充足且消费者容易获得大部分高能量食品的环境可能会导致卡路里的过度消耗。 (C) 2004 Elsevier Inc. 保留所有权利。
The energy density (kcal/g) and the portion size (g) of foods have been identified as two properties of foods that can modulate energy intake. Recent studies have shown that when either the energy density or the portion size of foods is increased, energy intake increases. Within a meal, when both factors are increased simultaneously, their effects are independent and add together to increase energy intake. On the other hand, reducing the energy density of a first course, while increasing the volume that is consumed, leads to a decrease in energy intake at the entire meal. The mechanisms by which both factors exert their influence are not well understood but likely include cognitive and orosensory factors as well as physiological controls related to gastric distention and gastric emptying. Findings from studies in this area of research provide evidence that the energy density and the portion size of foods are important determinants of energy intake. An environment in which the food supply is ample and large portions of energy-dense foods are readily available to consumers can contribute to an overconsumption of calories. (C) 2004 Elsevier Inc.
