重转这两帖子，里面全面的回答了你的问题1. 新加坡全脂牛奶全面评估 http://bbs.huasing.org/sForum/bbs.php?B=170_11831766 2. 新加坡0-24m膳食指南 http://bbs.huasing.org/sForum/bbs.php?B=179_11844146 里面很清楚的说明，1岁到2岁间应喝全脂牛奶，2岁以上可酌情改喝低脂或脱脂。酌情是说如果你家宝宝属于比较胖的，已经有overweight的迹象，就要考虑给低脂或脱脂牛奶了。如果像我家这种精瘦型的，就继续全脂好了。

可以喝UHT奶和鲜奶相比，味道有些许不同，小部分营养流失。 The UHT process might cause some loss of folate, vitamin C (which is already low in milk), vitamin B12, and thiamin. Though some people might not detect taste differences between fresh and UHT milk, others may noticed a slightly sweeter or "cooked" taste to UHT products, due to the higher heat treatment.
