Antioxidants are substances which reduce oxidative stress and the production of free radicals in humans which affects normal cell function and sometimes leads to cell death. For instance LDL cholesterol (low density lipoprotein) oxidation appears to trigger the process of formation of blockages, which results in atherosclerosis and finally causes cardiovascular disease. Antioxidants rich foods contain nothing but vitamins, minerals, glutathione, phytochemicals, polyphenols etc. Antioxidants rich foods can prevent cancer, diabetes, heart diseases, rheumatoid arthritis, viral infection, and neurological diseases like Alzheimer’s disease etc.
Foods Rich in Antioxidants:
Glutathione: This ‘master antioxidant’ has the ability of improving the functioning of all the other antioxidants, including vitamin C and E, CoQ10, alpha-lipoic acid etc. these proteins provide all the essential key amino acids for glutathione synthesis. It can also be provided by curcumin which is a component found in turmeric, raw dairy products, grass-fed meat and eggs.
CoQ10 (Ubiquinone): This substance is crucial for the human body after it gets converted into a broken down form called ubiquinol. It improves energy production, the immune system, nervous system and the health of our heart. Thus ubiquinol supplementation is useful in many cases.
Alpha- Lipoic Acid (ALA): Regenerates antioxidants, like vitamin C and E and glutathione. Yeast, liver, kidney, spinach, broccoli, and potatoes are rich sources of alpha-lipoic acid.
Reserveratrol: It can cross the blood-brain barrier and protect the brain and the nervous system. Grapes, vegetables, cocoa and red wine are rich sources of resveratrol.

Carotenoids: These organic pigments are found in peppers, kiwi, maize, grapes, squash, oranges, egg yolk etc. it provides health benefits by decreasing the risk of certain cancers and eye diseases.
Polyphenols: It helps in lowering the risk of heart attacks and strokes, glaucoma and high cholesterol. Regular consumption of organic green tea and tulsi tea provides this antioxidant in large amounts.
Phytochemicals: These plant compounds reduce inflammation and eliminate carcinogens from the body. Berries like blueberries, blackberries, cranberries and raspberries contain powerful phytochemicals that inhibit the DNA binding of certain carcinogens. Green leafy vegetables are rich in phytochemicals.
Vitamins: The vitamins like vitamin C, vitamin E, vitamin D and vitamin A can act as effective antioxidants. Grapes, berries, pomegranate, orange, guava, avocado, tofu, nuts, oil seeds, fish, mushrooms, dairy products and eggs contain an ample amount of these antioxidants.
Herbs and Spices: Ground cloves, ground cinnamon, oregano, turmeric, ginger, and garlic are also excellent resources of antioxidants. Also, almonds, walnuts, and hazelnuts are first-rate antioxidant rich foods.
