Habit-forming foods can alter brain activity

A recent study published in the journal Cell Metabolism suggests eating fatty or sugary snacks alters our brain activity and creates lasting preferences for these less-healthy items.

For the study, researchers at Yale University and the Max Planck Institute for Metabolism Research in Germany gave one group of participants a high-fat, high-sugar yogurt twice daily for eight weeks, while another got a low-fat, low-sugar version. Aside from that, both groups continued their normal eating habits.

At the end, the groups rated puddings with varying fat concentrations and apple juices with a range of sugar levels, and also underwent MRI scans. The scans showed the treat increased brain activity in the group that had eaten the high-fat, high-sugar yogurt, but not in the other. The researchers concluded fatty, sugary snacks activate the brain's dopamine system, which gives people a feeling of motivation or reward.

根本停不下来！研究：垃圾食品正在改变你的“脑回路”

近日发表在《细胞代谢》上的一项研究表明，吃高脂肪或含糖的零食会改变我们的大脑活动，并让我们对不太健康的食物产生持久的偏好。

耶鲁大学和德国马克斯·普朗克代谢研究所的研究人员给一组参与者服用了高脂肪、高糖酸奶，每天两次，持续八周；而另一组参与者则服用了低脂、低糖酸奶。除此之外，两组人都保持着正常的饮食习惯。

实验结束后，两组人分别品尝了不同脂肪浓度的布丁和不同甜度的苹果汁，并做出评价。参与者们也接受了核磁共振扫描。扫描显示，食用高脂肪、高糖酸奶一组人的大脑活动增加，而另一组人则没有。研究人员因此得出结论，高脂肪、含糖的零食会激活大脑的多巴胺系统，给人一种收获动力或受到奖励的感觉。

A recent study 1 in the journal Cell Metabolism suggests eating fatty or sugary snacks alters our brain activity and creates lasting preferences for these less-healthy items.

For the study, researchers at Yale University and the Max Planck Institute for Metabolism Research in Germany gave one group of 2 a high-fat, high-sugar yogurt twice daily for eight weeks, while another got a low-fat, low-sugar version. Aside from that, both groups continued their normal eating habits.

At the end, the groups rated puddings with 3 fat concentrations and apple juices with a range of sugar levels, and also underwent MRI scans. The scans showed the treat increased brain activity in the group that had eaten the high-fat, high-sugar yogurt, but not in the other. The researchers concluded fatty, sugary snacks activate the brain's dopamine system, which gives people a feeling of motivation or reward.
