众所周知,高脂食物不利健康。法国研究人员通过老鼠实验发现,儿时吃高脂食物会影响到大脑“奖励系统”的发育,致使长大了也难改这个习惯。波尔多大学研究人员先坚持给雄性老鼠喂食3个月的高脂食物,从它们断奶到成年,然后把实验鼠分为两组,一组先后注射两针盐水,一组先后注射两针安非他命,一种能触发大脑多巴胺系统的兴奋剂。研究人员发现,与健康老鼠相比,这些实验鼠长大后会更渴望吃高脂肪食物,吃垃圾食品的快感会大大增加。 It is well-known that high-fat foods are unhealthy. French researchers found through mouse experiments that when they eat high fat foods in their childhood they can affect the development of the brain’s “reward system” and make them grow up hard to change this habit. Researchers at the University of Bordeaux first insisted on feeding male rats with high-fat foods for 3 months from their weaning to adulthood. The rats were then divided into two groups. One group received injections of two doses of saline and one group received two doses of amphetamine one after another A stimulant that triggers the brain’s dopamine system. The researchers found that when compared with healthy mice, these mice grew more hungry for fatty foods and their junk food pleasure was greatly increased.
