Whole Milk

 Whole milk isn't made wholly of fat, or largely of fat, or even substantially of fat. In fact, it doesn't contain much fat all. Whole milk is actually only about 3.5 percent fat, and it’s the closest to the way it comes out of the cow. There also are other options for those who have different health needs or taste preferences, including reduced-fat (2 percent), low-fat (1 percent) and fat-free milk. Whole milk sales have dropped more than 61 percent since 1975 according to data from the USDA. Over that same period, 2 percent milk sales have more than doubled, and 1 percent and nonfat milk sales have nearly tripled.
