There are four main types of cow's milk: whole milk, 2 percent milk, 1 percent milk and fat-free milk. The fat content in milk can be adjusted using centrifugal force. According to Organic Valley, a company that makes milk products, the butterfat removed from whole milk can be reused to produce buttermilk or butter.
Whole Milk
Whole milk is milk that has not had its fat content reduced. One cup of whole milk contains 8 g total fat; 5 g of these are saturated fat. This type of milk has the highest fat content of any cow's milk. According to the U.S. Department of Agriculture's nutritional database, a 1-cup serving of whole milk contains 158 calories, 8 g protein, 13 g carbohydrates and 12 g sugar. One serving contains 12 percent of the daily recommended value of cholesterol and 30 percent of the daily recommended value of calcium.
2% Milk
Milk designated as 2 percent or low fat has a 2 percent fat-to-weight ratio. One cup of this type of milk contains 5 g total fat. A serving of 2 percent milk has 3 g saturated fat. One serving of 2 percent milk contains 139 calories, 10 g protein, 15 g carbohydrates and 13 g sugar. One serving also contains 7 percent of your daily recommended value of cholesterol and provides you with 35 percent of your daily value of calcium.
1% Milk
As with 2 percent milk, the percentage in this type of milk indicates the percent of fat to weight. One percent milk has roughly half of the fat of 2 percent milk. There are 2 g of total fat in 1 cup of 1 percent milk, and 2 g of the total fat is saturated fat. A serving of 1 percent milk contains 127 calories, 10 g protein, 16 g carbohydrates and 15 g sugar. One cup of 1 percent milk also contains 4 percent of your daily recommended value of cholesterol and 38 percent of your daily value of calcium.
Nonfat Milk
Nonfat milk has been entirely stripped of its fat molecules. This type of milk is not calorie free, however. And because nonfat milk contains carbohydrates and sugars, it can still affect your weight. This is a good option if you are limiting your fat intake or monitoring your cholesterol. One cup of nonfat milk has 92 calories, 9 g protein, 13 g carbohydrates and 12 g sugar. One serving has 2 percent of your daily value of cholesterol and 31 percent of your daily recommended value of calcium.
