目前,世界大多数国家都是一日三餐制,这似乎已成定论。但这“定论·对养生来说是否最理想,有没有更好的进餐制?事实上,这种“定论”已受到了挑战。一些研究者认为:日进三餐的弊端在于间隔时间太长,每餐的进食量偏大。虽然一天中摄取食物的总量绰绰有余,但实际上,身体却处于饥饱不匀的状态。在短暂的相对饥饿时,体内发生“能源危机”,不得不动员贮存的能量(主要为脂肪),甚至挖掘蛋白质以获得能量。一次摄食过多,又发生短暂的营养过剩。长此以往,身体健康便会受到损伤。另一方面,一次过饱的进食,无疑会加重胃肠的负担,扰乱各种生理功能的稳定,使许多一时还来不及吸收的营养素“穿肠而过”,白白流失掉,起不到营养作用。
At present, most countries in the world have three meals a day, which seems to have come to a conclusion. In fact, this “determination” has been challenged by some researchers: the shortcoming of having three meals a day is that the interval is too long , The food intake per meal is too large.While the total intake of food more than enough, but in fact, the body is in a state of hunger and drowsiness.In the relative short-term hunger, the body “energy crisis”, had to mobilize Stored energy (mainly fat), and even digging for protein to gain energy .Once eating too much, there is a brief nutritional surplus .In the long run, the health will be damaged.On the other hand, a full feeding, will undoubtedly aggravate The burden of gastrointestinal, disrupt the stability of a variety of physiological functions, so many of the time too late to absorb the nutrients “through the intestine,” lost in vain, can not play a nutritional role.
