For all dinner tables, a glass of milk seems to be a must. At least it was when I was growing up. It is widely believed that milk is a must in building strong bones and teeth. There’s no doubt that dairy products, especially milk, are high in protein and calcium, and Vitamin D and Vitamin A are added to most milk products.
While it’s well known that our bones need calcium, some studies suggest that high calcium intake doesn’t necessarily lower a person’s risk for fractures（骨折）. A Harvard study found that people who drank two or more glasses of milk had no greater protection from breaking a bone than those who drank a glass or less a week.
There is no doubt that we need calcium. Some anti-dairy supporters claim dairy products can lead to heart disease. Much of this claim is based on high-fat dairy products, like cheese and cream, which may indeed lead to some health problems. Some studies have linked high milk intakes with a risk of prostate cancer; this seems also to be caused by high-fat dairy products, but not by dairy products in general.
Although milk has always been regarded as the most important thing we need for our bones, one of the most important things in strengthening bones and reducing the risk of osteoporosis（骨质疏松）is weight-bearing exercise, such as jogging, walking, and weight lifting.
Perhaps we should think of dairy products as less like a nutrient and more like a food. If you like it, eat it. If not, find something else to eat. Some claims may not be completely true. When I eat cream, I’m not thinking about calcium, protein, or any such thing. I’m thinking it is delicious.
