由食物摄入体内的营养物质,由于胃、胰、肠腺的消化液的适当作用之后便分解成为最简单的物质,于是吸收到血液中。我们根据吸收了的物质的量,来判定各种营养物质及所有的食物在体内的吸收率,因此把被肠绒毛吸收入血液的物质作为被吸收的量。食物的吸收率是和消化器官的状态,食物的组成,特别是食物的调制方法有关。 By the food intake of nutrients in the body, due to the stomach, pancreas, intestinal gland digestive juice appropriate role after decomposition into the most simple substance, then absorbed into the blood. We determine the rate of absorption of various nutrients and all foods in the body based on the amount of substance absorbed, so that the substance absorbed into the blood by the intestinal villi is taken as the absorbed amount. The rate of absorption of food is related to the state of the digestive system, the composition of the food, and especially the way in which the food is prepared.
