     For all the dinner table, a glass of milk seems to be a constant, at least it was when I was growing up.

It was widely believed that milk was integral in building strong bones and teeth. There's no doubt that

dairy products (乳制品), and milk in particular, are high in protein and calcium, and most milk products

are supplemented with Vitamin D and A.

     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's no doubt that we need calcium. Some anti-dairy supporters claim that dairy can lead to heart

disease. Much of this claim is based on high fat and high dairy products, like cheeses and creams, which

may indeed contribute to cardiovascular problems. Some studies have linked high milk intakes with a risk

of prostate cancer; this seems to be caused by high-fat dairy products, not dairy in general.

     Although milk was always regarded as one of the most important thing we need for our bones, yet

least promoted, factors involved in strengthening bones. Perhaps we should think of dairy as less like a

nutrient and more like a food. If you like it, eat it. If not, find some others. Because some claims may not

be completely true, when I eat a cream, I'm not thinking about calcium, protein, or any such thing I'm

thinking delicious.
