美国儿科学会：母乳喂养可降低婴儿患糖尿病的风险

据报道，对于纯母乳喂养至少3个月、因而避免了接触牛奶蛋白的婴儿，Ⅰ型糖尿病的发生率可降低高达30% 。Ⅰ型糖尿病的发病机制据推测可能是婴儿接触了牛奶β-乳球蛋白，后者激发了与胰腺β细胞有交叉作用的免疫反应进程。而在上述婴儿中，Ⅱ型糖尿病的发病率据报道能降低40%，这可能反映了母乳喂养在体重控制与饮食自我调控方面长期、积极的效果。 Up to a 30% reduction in the incidence of type 1 diabetes mellitus is reported for infants who exclusively breastfed for at least 3 months, thus avoiding exposure to cow milk protein. It has been postulated that the putative mechanism in the development of type 1 diabetes mellitus is the infant’s exposure to cow milk β-lactoglobulin, which stimulates an immune-mediated process cross-reacting with pancreatic β cells. A reduction of 40% in the incidence of type 2 diabetes mellitus is reported, possibly reflecting the long-term positive effect of breastfeeding on weight control and feeding self-regulation. 来源：http://pediatrics.aappublications.org/content/129/3/e827.full 翻译：http://www.weibo.com/2514526082/zvv2Aev2H
