To understand the influence of food form on satiety, 19 male participants attended two separate test sessions to consume either a liquid-solid meal (LS), which consisted of whole pieces of vegetable in a broth, or a liquid version of the same ingredients [liquid meal (LM)]. Following this meal, appetite questionnaires and blood samples were collected at regular intervals over 3 h. An ad libitum meal was then served and the amount eaten recorded. Fullness and preoccupation with food were higher following the LM compared with the LS (p = 0.001 and p = 0.031, respectively). Postprandial plasma concentration of cholecystokinin (p < 0.001) and insulin (p < 0.001) was higher and plasma glucose concentration was lower (p = 0.003) following the LM compared with the LS. However, there was no difference in the food intake at the subsequent meal. These results suggest that food form has a limited effect on satiety; however, the influence of the postprandial insulin response warrants further attention.
为了理解食物形态对饱腹感的影响，19 名男性参与者分别参加了两次测试，分别食用了一种液体-固体餐（LS），其中包括汤中的完整蔬菜，或相同成分的液体餐（LM）。在用餐之后，在 3 小时内定期收集食欲问卷和血液样本。然后提供一份随意餐，并记录所吃的量。与 LS 相比，LM 后饱腹感和对食物的关注更高（p=0.001 和 p=0.031）。与 LS 相比，LM 后胆囊收缩素（p<0.001）和胰岛素（p<0.001）的餐后血浆浓度更高，血糖浓度更低（p=0.003）。然而，在下一顿餐时的食物摄入量没有差异。这些结果表明，食物形态对饱腹感的影响有限；然而，餐后胰岛素反应的影响值得进一步关注。
