The snack food potato chips induces food intake in ad libitum fed rats, which is associated with modulation of the brain reward system and other circuits. Here, we show that food intake in satiated rats is triggered by an optimal fat/carbohydrate ratio. Like potato chips, an isocaloric fat/carbohydrate mixture influenced whole brain activity pattern of rats, affecting circuits related e.g. to reward/addiction, but the number of modulated areas and the extent of modulation was lower compared to the snack food itself.
休闲食品薯片会促使随意进食的大鼠摄入食物，这与大脑奖赏系统及其他神经回路的调节有关。在此，我们表明，饱腹大鼠的食物摄入是由最佳脂肪/碳水化合物比例触发的。与薯片一样，等热量的脂肪/碳水化合物混合物会影响大鼠的全脑活动模式，影响与奖赏/成瘾等相关的神经回路，但与休闲食品本身相比，受调节的区域数量和调节程度较低。
