“Old wives’ tales” are beliefs passed down from one generation to another. 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.

Sticky sweets made with grains(谷物) tend to cause more problems than sweets made with simple sugars.
