Foods eaten during snacking events contribute significantly to our daily energy intake. Depending on the food choices made during these snacking episodes, i.e., the energy density of the selected foods and the portion size eaten, this can lead to excessive consumption of calories. Many foods that are high in energy density are often highly liked and may easily be overconsumed if presented in large portions. Downsizing of these foods has shown some evidence for a reduction in energy intake, especially in lab conditions. However, in free living conditions, when additional confounding factors interfere, results are less convincing. One highly important influence on eating episodes, especially during snacking, is food satisfaction. The aim of this work is to address the energy density of snacking events by combining high energy foods with low energy dense foods whilst retaining a high level of satisfaction. The understanding of the drivers of the satisfaction related to the food combinations will be part of this work.

吃零食时吃的食物对我们每天的能量摄入有很大的贡献。根据在这些零食事件中所做的食物选择，即，所选食物的能量密度和所吃的份量，这可能会导致卡路里的过度消耗。许多高能量密度的食物通常很受欢迎，如果大部分都很容易被过度消费。这些食物的减少已经显示出一些减少能量摄入的证据，特别是在实验室条件下。然而，在自由生活条件下，当额外的混杂因素干扰时，结果就不那么令人信服了。一个非常重要的影响进食事件，特别是在吃零食，是食物的满意度。这项工作的目的是通过将高能量食物与低能量密集食物相结合来解决零食事件的能量密度，同时保持高水平的满意度。了解与食物组合相关的满意度驱动因素将是这项工作的一部分。
