3. Coenzyme Q 10
Coenzyme Q 10 is the chief energy supplier to your body cells. It declines with age. That’s why elderly people feel tired quickly. This antioxidant keeps oxidative stress in check. If you have this enzyme in sufficient amount in your body, you will be fitter in mind and body as you age.
Eat peanuts, soybeans, fatty fish, chicken, spinach, broccoli, lentils, oranges, and strawberries frequently for adequate supply of this enzyme.
