Question

what are antioxidants? benefits of antioxidants
antioxidants are substances or nutrients in our foods which can prevent or slow the
oxidative damage to our body. when our body cells use oxygen, they naturally produce
free radicals (by - products) which can cause damage. antioxidants act as \free radical
scavengers\ and hence prevent and repair damage done by these free radicals. health
problems such as heart disease, macular degeneration, diabetes, cancer etc are all
contributed by oxidative damage. indeed, a recent study conducted by researchers
from london found that 5 servings of fruits and vegetables reduce the risk of stroke by
25 percent. antioxidants may also enhance immune defense and therefore lower the risk
of cancer and infection.
