1. You absorb less of the nutrients without the fat. The nutrients in milk, vitamins D, E, and A, are fat-soluble, which means your body absorbs them better when they're delivered via fat. What's more, the vitamin K found naturally in butterfat gets left behind altogether. 全脂牛奶中的脂肪有助于人体吸收脂溶性的VD,E,A。Vitamin K 存在于黄油脂肪内，因此脱脂牛奶不含此维生素。

2. Skim and low-fat milk contain powdered milk, which is made with oxidised cholesterol, a carcinogen. Oxidised cholesterol can contribute to the build-up of plaque in your arteries. On the other hand, untreated cholesterol in whole milk is an antioxidant.脱脂或者低脂牛奶含奶粉，而奶粉有氧化胆固醇，属致癌物。氧化胆固醇会堵塞血管，而全脂奶中未处理过的胆固醇是抗氧化剂。

3. Milk producers have started adding sugary flavouring to skim and low-fat milk to encourage kids to drink more of it. This means more empty calories in milk that releases fewer nutrients into your body. So that doesn't make a whole lotta sense.牛奶厂家已经开始在低脂奶中加入甜味以吸引小孩。

4. Skim can leave you feeling unsatisfied, which leads many people to fill up on less-healthy "non-fat" foods. This is because saturated fats like those found in whole milk trigger the release of the hormone cholecystokinin, which makes you feel full.脱脂奶可能会让人不满意而吃更多的不健康食物。而全脂奶中的饱和脂肪容易让人产生吃饱的感觉。

5. Skim milk has been linked with "transient" weight loss in studies. This means you may lose some weight from cutting out whole milk at first, but then you're likely to gain back that weight.脱脂奶会让人体重先降低后升高的“过渡型”体重减轻。

6. Fats slow the release of sugar into your bloodstream, reducing the amount that can be stored as fat. This is an argument for letting some "healthy" fats into your daily diet overall, and they don't have to come from milk. They can come from olive oil and nuts, for example.脂肪让糖进入血液的速度变慢，从而减少可能转换为脂肪的糖分。
