What is the difference between skim, low fat and full cream milk regarding vitamins and macronutrients?

The main difference is energy and fat: skim and low-fat milk contain less energy and fat than full cream milk. Some fat-soluble vitamins, such as vitamin A, can also differ.

Full cream, low-fat (or lite) and skim milk are all nutritious choices, providing important nutrients, including protein, calcium, vitamin B12 and iodine. 

The main difference is the amount of energy and fat they contain: 

• Full cream milk retains its natural milk fat. 
• Low-fat (lite) milk has some of the fat removed. 
• Skim milk has almost all of the fat removed. 

The protein and carbohydrate content is generally similar, so choosing a lower-fat milk doesn’t mean missing out on these nutrients. Calcium and B vitamins are also generally present in similar amounts across the three types. 

One difference is vitamin A, which is naturally associated with milk fat. Removing most of the fat can reduce the amount of vitamin A, although some low-fat and skim milks may be fortified with vitamin A. 

The best milk for you depends on your individual nutrition needs, preferences and overall diet. Full cream, low-fat and skim milk can all contribute important nutrients to your diet.
