“Drink your milk. It’s good for you!” You’ve probably heard that many times, and it’s true. Milk contains calcium, which is a necessary nutrient for keeping bones and teeth healthy and strong. The U.S. government even requires milk as part of the National School Lunch Program, saying that students should drink one cup of fat-free or low-fat milk at each meal.

Last Thursday, however, a group of doctors asked the government to remove milk from the lunch program. The Physicians Committee for Responsible Medicine (PCRM) says, “Milk is high in sugar, high in fat and high in animal protein, all of which have negative effects on health.” “One of the only reasons people talk about dairy, or promote it, is that it is going to help build strong bones.” says Dr. Neal Barnard, president of the PCRM. There are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient.

Of course, calcium is important for healthy bones and teeth, but your genes, how much vitamin D you take in and getting an hour’s worth of exercise every day all play a part.

Some nutritionists disagree with the idea that milk isn’t important. Keri Gans, a dietitian, says, “I think it’s irresponsible to take away this beverage that children enjoy, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line.”

The U.S. government is studying the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor at New York University, puts it best: “Milk has nutrients. Other foods have the same nutrients. It’s just a food. Like other foods, too much might be a problem.”
