     "Old wives tales" are beliefs lasting for many generations. For example, most of us remember our parents'

telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some

of them agree with present medical thinking, but others have not passed the test of time.

     Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now

report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one

carrot a day can reduce the possibility of getting this disease by 40%. Garlic is good for you, too. It can kill the

type of virus that causes colds.

     Unfortunately, not all of Mom' s advice passed the test of medical studies. For example, generations of

children have been told not to go swimming within an hour after eating. But research suggests that there is no

danger in doing so. Do sweets cause tooth problems? Well, yes. However, sticky sweets made with grains tend

to cause more problems than sweets made with simple sugars.

     Even though science can tell us that some of our traditional beliefs don't hold water, there is still a lot of

truth in the old wives' tales. After all, much of this knowledge has been accumulated from thousands of years

of experience in family health care. We should respect this body of knowledge even as we search for clear

scientific support to prove it true or false.
