Question: what is the difference between whole milk and 2 percent milk?
Answer: But, the differences aren't that great. One cup of whole milk has 150 calories and 8 grams of fat, while the same serving of 2-percent fat milk has 120 calories and 5 grams of fat. ... Vitamin and mineral content is also similar, although 2-percent milk is a slightly better source of vitamin A and calcium.
