Milk: does a body bad?
It is bad enough that the dairy industry recently petitioned the FDA to sneak artificial sweeteners into chocolate milk. They want their “shake and eat it, too” by pushing milkshake-like flavored milk drinks into schools as a “healthier” option, even though they have 30 grams of sugar per cup. By cutting the sugar and adding artificial sweeteners to low fat or non-fat milk drinks, the idea is that they would be healthier. Except for the fact that recent studies have found that one diet drink a week increases your risk of type 2 diabetes by 33 percent and a large diet drink increases the risk by 66 percent.
What about low fat milk or non-fat milk? These are the healthier options, right? Wrong.
Ludwig and Willett note that there is scant evidence that fat makes you fat, despite this commonly held mistaken belief. Reducing fat in milk reduces its ability to satisfy the appetite (which fat does) and can promote overeating and hunger. Often, the fat in the diet is replaced with sugar and refined carbohydrates, which clearly has been shown to promote obesity and type 2 diabetes.
Studies show that reducing fat in the diet, which parallels an increase in starch and refined carbohydrates in the diet, not only increases hunger but also may actually slow metabolism. In one study, Dr. Ludwig found that those who ate a low fat, higher glycemic diet burned 300 calories less a day that those who ate an identical calorie diet that was higher in fat and lower in glycemic load. For those who ate the higher fat, lower glycemic diet, that’s like exercising an extra hour a day without doing anything!
More concerning still is that, in studies of kids and adults, those who consumed low fat milk products gained more weight than those who ate the full fat whole milk products. They seemed to increase their overall intake of food because it just wasn’t as satisfying as the real thing. In fact, those who drank the most milk overall gained the most weight. It makes logical sense. Milk is designed to quickly turn a little calf into a big cow and contains over sixty different hormones, most designed to boost growth.
But shouldn’t we stick to low fat milk to reduce our intake of saturated fat? The fact is that, while your LDL or bad cholesterol goes down by reducing saturated fat in the diet, the protective cholesterol, HDL, actually goes up by eating saturated fat improving the ratio of total to HDL cholesterol, which is the most important marker of your risk of heart disease. Switching out saturated fat for carbohydrates actually increased the risk of heart attack in a 12-year study of 53,544 adults. In fact, the whole story of the evil of saturated fats is in great debate. The evidence for linkage to heart disease turns out to be pretty weak indeed.
If you ate only whole foods, fruits, vegetables, beans, nuts, seeds, and whole grains (not whole grain flour), you might be better off overall (although a recent scientific review of saturated fat dismissed the very notion that is it bad for you). But sadly, that is not what most Americans do when they switch to low fat.
The sad thing is that many schools and “healthy” beverage guidelines encourage the idea that flavored milk is better than soda and that getting kids to drink more milk by any means is a good idea. This is dangerously misguided.
There are 27 grams of sugar in 8 ounces of Coca Cola and a whopping 30 grams of sugar in 8 ounces of Nestlé Chocolate Milk. Sugar is sugar and drives obesity and diabetes. It is not a good way to get kids to drink milk.
But that begs the bigger question. Do kids need milk? Is milk necessary for healthy bones and preventing osteoporosis? The data are clear, but our government polices don’t reflect the science.
