概括
人类不会根据能量密度 (ED) 调整食大小,从而导致被动的过度消费. 更高的ED食物增加了总能量摄入量,这表明重新配方可以对抗肥胖.
科学领域:
- 营养科学 营养科学
- 人体生理学 人体生理学
- 肥胖问题研究研究
背景情况:
- 关于人类是否根据能量密度 (ED) 调节食大小,存在相互矛盾的研究.
- 一些研究表明,更高的ED餐量 (>1.7-2 kcal/g) 会导致更小的餐量.
- 在饮食摄入研究中",被动过度消费"的概念仍在争论中.
研究的目的:
- 调查成年人食能量密度 (ED) 和食大小之间的关系.
- 为了确定是否增加ED导致餐食大小的补偿性减少或被动过度消费.
- 评估餐饮ED对后续能量摄入的影响.
主要方法:
- 两项随机交叉实验与成年参与者进行.
- 实验1:参与者自发地食用低,中或高ED的熟悉甜点.
- 实验2:参与者消费的ad libitum午餐被操纵为低,中,或高的ED;随后的能量摄入量也被测量.
主要成果:
- 在实验1中,与中等和低ED相比,高ED甜点导致能量摄入量显著增加.
- 在实验2中,饮食大小 (克) 在ED水平之间没有差异,显示了ED和能量摄入 ("被动过度消费") 之间的线性关系.
- 在ED条件之间没有观察到后期能量摄入量的显著差异.
结论:
- 与一些建议相反,更高的食能量密度并没有导致食大小的补偿性调整.
- 增加的能量密度与更大的总能量摄入量有关,支持"被动过度消费"模型.
- 重组高能量密度的食物可能是减少人口水平能量摄入量和肥胖的可行策略.

Crossover Experiments
2.8K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Confirmation Biases
5.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
