Eat plenty of fiber.

Dr. Oz also explains that one key to staying young is to keep your intestines healthy and bowels regular. This takes about 25 grams of fiber a day.  Fiber works by keeping all the nutrients you eat in your intestines and releasing them as needed. It can be found in fruits, vegetables and foods rich in whole grains. Try the following:

  • Wrap sandwiches in whole wheat tortillas instead of white.
  • Choose whole-grain cereal for breakfasts and snacks.
  • Try brown rice or whole-wheat pasta.
  • Have steel-cut oatmeal for breakfast.
