An apple a day may not keep the doctor away, but three apples a day may cut your stroke risk.

The American Heart Association, citing research from a new British study, says that adding seven grams of fiber to your daily diet can lower the risk of first-time stroke by 7 percent. Each additional seven grams of fiber lowers the risk by another 7 percent.

Adding fiber is easy. One apple, for example, has 2.8 grams of fiber. If you start your day with two pieces of white-bread toast (1.2 grams of fiber), try whole wheat instead (3 grams). Other excellent sources of fiber are beans, bran cereals and vegetables.
