Here are four milk myths you might have heard, and why you should consider answering the cowbell more often.
Claim #1: “Milk is a fat-burning food.”
The Truth: Maybe. In a 6-month study, University of Tennessee researchers found that overweight people who downed three servings a day of calcium-rich dairy lost more belly fat than those who followed a similar diet minus two or more of the dairy servings. In addition, the researchers discovered that calcium supplements didn’t work as well as milk. Why? They believe that while calcium may increase the rate at which your body burns fat, other active compounds in dairy (such as milk proteins) provide an additional fat-burning effect.

Claim #2: “Drinking milk builds muscle.”
The Truth: Absolutely. In fact, milk is one of the best muscle foods on the planet. Milk is full of high-quality protein: about 80 percent casein and 20 percent whey. Whey is known as a “fast protein” because it’s quickly broken down into amino acids and absorbed into the bloodstream—perfect for post-workout consumption. Casein, on the other hand, is digested more slowly—ideal for providing your body with a steady supply of smaller amounts of protein for a longer period of time, such as between meals or while you sleep.

Claim #3: “Cows are given antibiotics. Doesn’t that make their milk unhealthy?”
The Truth: No one really knows. Some scientists argue that milk from cows given antibiotics leads to antibiotic resistance in humans, making these types of drugs less effective when you take them for an infection. But this has never been proven.
It is true that hormones and antibiotics have never been part of a cow’s natural diet, and they have been shown to have adverse effects on the animals. Canadian researchers, for example, discovered that cows given hormones are more likely to contract an udder infection called mastitis. If you’re uneasy, you can purchase antibiotic-free (and typically hormone-free, as well) milk from producers like Horizon and Organic Valley at most major supermarkets. The cows will certainly thank you.

Claim #4: “Fat-free milk is much healthier than whole.”
The Truth: Nope. While you’ve probably always been told to drink reduced-fat milk, the majority of scientific studies show that drinking whole milk actually improves cholesterol levels—just not as much as drinking fat-free does. One recent exception: Danish researchers found that men who consumed a diet rich in whole milk experienced a slight increase in LDL cholesterol (six points). However, it’s worth noting that these men drank six 8-ounce glasses a day, an unusually high amount. Even so, their triglycerides—another marker of heart-disease risk—decreased by 22 percent. The bottom line: Drinking two to three glasses of milk a day, whether it’s fat-free, 2%, or whole, lowers the likelihood of both heart attack and stroke—a finding confirmed by British scientists.
