100 diseases are linked to the free radical damage and poor
antioxidant intake.
Formation of these harmful
electrons/ free radicals can increase due to:
-
-
-
-
-
-
Increased
unwanted bacteria in gut
-
Increased
consumption of high and bad fat food
-
Excessive
exposure to harmful chemicals and drugs due to pollution.
All
these changes are the result of rapidly changing lifestyle and
poor eating habits that lead to lowered antioxidant status.
To save ourselves from the free radical damage and protect from
premature aging and chronic degenerative diseases, we need to
improve the consumption of antioxidants in our diet.
Antioxidants
are natural substances found in our bodies and food, which neutralize
free radicals and protect cells. They are mainly found in fruits
and vegetables, whole grains, nuts and seeds. It is these chemicals
in food that neutralize free radicals- and prevent the oxidative
damage to cells and tissues.

Antioxidants
are of two types nutritional and non-nutritional.
1. Nutritional
Antioxidants: The antioxidants present in natural
foods are common vitamins and minerals in our diet that exhibit
the antioxidant function. The most commonly occurring nutritional
antioxidants include:
