Quick Summary

Low-fat milk is a dairy product that has had most of its milk fat removed. It typically contains 1-2% fat, making it a lower-fat alternative to whole milk.1

Milk, in general, is an emulsion of fat and protein in water, containing carbohydrates (lactose), minerals, and vitamins. The composition of milk varies among mammals, but cow's milk is a common source for human consumption.12

Low-fat milk is a good source of calcium and protein. Compared to whole milk, it has fewer calories and less cholesterol, and it is often fortified with vitamin A. While dairy products can be a source of saturated fat and sodium, which are linked to cardiovascular disease and high blood pressure, low-fat options can help reduce these risks.234
