13. FALSE. Margarine eaters have twice the rate of heart disease as butter eaters.

15. FALSE. The real culprit is usually starchy foods, such as chips, pretzels, crackers and cookies, along with bananas, dried fruit and other fruits that are low in water. Unlike sugar, which saliva rapidly washes away, starchy foods hang out in the spaces between and on top of teeth for a long time.
