近十多年来的研究表明,母乳是婴儿最适宜的食品,有利于婴儿健康成长,其所含的各种营养物质最适合婴儿消化吸收,且具有最高的生物利用率,同时母乳含有丰富的抗感染物质,利于保护婴儿少得疾病。在婴儿出生后4—6个月内纯母乳喂养的婴儿患病机会低于用母乳代用品喂养儿的2.5倍,因而患腹泻而致死的人数要少25倍。其次母乳喂养还被证实是天然的避孕方法,有延长生育间隔的作用。据世界卫生组织统计,在世界范围内,母乳喂养发展模式经历了一个从高母乳喂养率转向普遍下降而后又再上升的曲折过程。
Nearly 10 years of research shows that breast milk is the most suitable baby food, is conducive to the healthy growth of infants, which contains a variety of nutrients most suitable for infant digestion and absorption, and has the highest bioavailability, while breast milk is rich in Anti-infective substances, help protect infants less disease. Infants who are exclusively breast-fed have a chance of being less than 2.5 times infants fed breast-milk substitutes within 4-6 months of birth, resulting in 25-fold fewer deaths from diarrhea. Second, breastfeeding has also been proven to be a natural contraceptive method with the effect of prolonging birth spacing. According to the statistics of the World Health Organization, the pattern of development of breastfeeding around the world has experienced a twists and turns from a high rate of breastfeeding to a general decline and then a rise again.
