Antioxidants - How They Affect Your Body?

Antioxidants are substances that help the body protect itself from harmful molecules called free radicals. Free radicals are not necessarily formed by medicines. It needs change to free radicals produced by enzymatic and nonenzymatic reactions/by inflammation and external factors like smoking x-rays, chemicals, industrial pollutants, ozone and certain drugs.

Antioxidants include vitamins C and E, beta carotene and minerals such as flavonoids and selenium; both of which are found in plants. The best kind of antioxidants the human body receives is from fruits and veggies. While flavonoids are found in red wine, fruits and in different types of tea; pharmaceutical companies also sell dietary supplements rich in antioxidants.

Antioxidants and their role in the human body:
Antioxidants play a great role in management, prevention and in the subsequent elimination of diseases such as various types of Cancers, Alzheimer’s and a few arthritis related conditions.

How safe are antioxidants for your body?
Medical practitioners are of the opinion that the best source of antioxidants is your natural sources rather than dietary supplements. Over abuse of antioxidants can be lethal for your body. It is always advised to have plenty of fruits and vegetables each day.

Not only does diet contribute to antioxidants, the body too employs certain mechanisms to protect itself from damage. Antioxidant enzymes such as glutathione peroxidase and superoxide dismutase are few such enzymes. Micronutrients such as iron, copper, selenium, zinc and manganese are required to help facilitate these mechanisms. Inadequate intake of these minerals in your diet might reduce the activities performed by antioxidants; these claims have been backed by scientific studies. If you wish to discuss about any specific problem, you can consult a General Physician.
