The Benefits of Antioxidants – To Prevent Chronic Diseases And Support Anti Aging

What are Antioxidants?

Antioxidants are natural substances found mainly in vegetables, fruits, nuts and spices that help prevent or reduce oxidation which occurs at the cellular levels. They do this by removing "free radicals", which, if left alone could oxidize cells – leading to inflammation and chronic diseases like diabetes, joint diseases, atherosclerosis, cancer, dementia and degenerative eye diseases. These harmful chemicals also accelerate the aging process.

What are Free Radicals?

Free radicals are atoms or molecules with an unpaired electron in an atom's outer shell. Being chemically unstable, they are highly reactive and able to cause damage to cells in the body. Some researchers believe that aging occurs because cells accumulate free radical damage over time.

The main contributing factors to excess free radicals in the body are eating the wrong food, stress, pollutants, smoking, over exposure to ultra violet light and harmful bacteria.

The intake of certain prescription drugs and chemotherapy are also linked to free radical formation in the body.

Foods high in free radicals include oil and fats (when heated to high temperature like in frying) overcooked meats and processed meats.

Eating too much sugary foods that cause the blood sugar to spike could also lead to an increase in this harmful chemical in the body
