Skim milk is a lower fat option than whole milk, making it a lower calorie option for people looking to control their weight or reduce their consumption of fat. It can also be a source of protein, calcium and other important nutrients. However, some nutrients present in milk, such as vitamins A and D, are fat -soluble, which means that they are better absorbed in the presence of fat. Consequently, it is important to ensure that the contribution in these nutrients is adequate if we regularly consume skim milk.
