脂肪是人体必需的营养素之一。它既是人体能源的宝库,又是各种组织器官的构造材料。此外,它还有种种重要生理功能,尤其是处在生长发育阶段的幼儿,机体新陈代谢旺盛,所需的营养素相对比成人多。幼儿饮食如果缺乏脂肪,将对生长发育和正常的生理功能产生不良影响。 1.会导致热量不足:脂肪发热量高,每克脂肪在体内氧化后,可产生1000卡热量,是同量糖类产热值的2倍;如果饮食中脂肪入不敷出,势必使用于建造组织器官,促进生长发育的蛋白质也转而供给热能。若长期缺乏脂肪,对小儿的健康发育,无异于釜底抽薪。
Fat is one of the essential nutrients of the body. It is not only the treasure house of human energy, but also the material of construction of various tissues and organs. In addition, it also has a variety of important physiological functions, especially in young children at the stage of growth and development, the body metabolism is strong, the nutrients required are relatively more than adults. If the lack of fat diet for young children, will have an adverse impact on the growth and development and normal physiological function. 1 will lead to lack of calories: fat, high calorie, per gram of fat in the body after oxidation, can produce 1000 calories, the same amount of sugar calorific value of 2 times; if the diet of fat make ends meet, is bound to be used to build tissue and organs , To promote the growth and development of protein is also converted to heat. If the long-term lack of fat, the healthy development of children, is tantamount to drastic salaries.
