constant,at least it was when I was growing up.It was widely believed that milk was integral(不可或缺的)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(补充)with Vitamin D and Vitamin A.
While it's well known that our bones need calcium,some studies suggest that high calcium intakes 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 antidairy 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(心血管的)problems.Some studies have linked high milk intakes with a risk of prostate cancer;this seems to be caused by highfat dairy products,not dairies in general.
Although milk is always regarded as one of the most important things 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.
