西班牙研究人员日前发表的一份研究结果显示,人无节制地贪吃不是因为饥饿,而是为了寻求生理上的愉悦和心理上的满足感。通常新生儿在母亲温暖的怀抱中吃下第一口食物,当饥饿感消失时,婴儿会感受到极大愉悦,于是食物和享受的感觉就永远地留在了记忆中。美国密歇根大学心理学家认为,抑郁会刺激大脑中的激素机制,促使人们过量吃喝。此外,大脑中的促肾上腺皮质激素会减弱人对诱惑的抵抗力。富含脂肪和糖分的食物,例如快餐,会刺激大脑产生愉悦物质,因此比萨饼、饮料、薯片和热狗最令人嘴馋。
A study published by a Spanish researcher recently showed that people are greedy not because of hunger but rather for seeking physical pleasure and psychological satisfaction. Usually the newborn eats the first food in the mother’s warm embrace. When the hunger disappears, the baby will feel great pleasure, and the feeling of food and enjoyment will remain in memory forever. University of Michigan psychologists believe that depression will stimulate the brain’s hormone mechanism, prompting people to eat too much. In addition, adrenocorticotropic hormone in the brain diminishes one’s resistance to temptation. Foods rich in fat and sugar, such as fast food, stimulate the brain to produce pleasant substances, making pizza, drinks, chips and hot dogs the most appetizing.
