吃食物的目的是为了从食物中吸取营养,以维持身体的需要,而食物在口腔内一般要经过牙齿的咀嚼和舌头的搅拌,再加上唾液的混合才能吞咽;唾液中的淀粉酶能使食物中的淀粉水解成麦芽糖,便于消化吸收。只有细嚼慢咽,食物到胃肠里才能充分消化,营养才容易被吸收。假如经常狼吞虎咽,囫囵吞枣,不仅不能充分吸收食物里的营养,还容易罹患慢性胃肠病。曾经有个医学家为了体验细嚼慢咽的好处,他每一口饭都咀嚼百次以后才下咽。过了好几年,他的健康状况明显好于同龄人。有些人喜欢用开水或汤泡饭吃,往往没有细嚼就匆忙下肚,增加了胃肠的负担,营养也吸收不好,经常如此,对身体十分有害。唾液中的溶菌酶对细菌有杀灭能力,因此,细嚼慢咽能起到一定的防癌作用。有的科学家曾试验,把有害的致癌物质放入试管内,将吐出的
The purpose of food is to absorb nutrients from food to maintain the body’s needs, and food in the mouth to go through the chewing of the teeth and tongue mixing, together with the saliva mixture to swallow; amylase in saliva can make Starch in food is hydrolyzed into maltose for digestion and absorption. Only slowly, the food can be fully digested in the stomach, nutrition is easy to be absorbed. If you often devour, swaddled, not only can not fully absorb the nutrition of food, but also easy to suffer from chronic gastrointestinal disease. Once there was a medical scientist in order to experience the benefits of chewing food, he chew every time after a meal hundred times to swallow. After several years, his health was significantly better than his peers. Some people like to use boiling water or soup to eat, often without a hint of hasty, increasing the burden of gastrointestinal, nutrition is also poor absorption, often so, very harmful to the body. Lysozyme in saliva has the ability to kill bacteria, therefore, can play a certain anti-cancer effect. Some scientists have tried to put harmful carcinogens into the test tube, will spit it out
