What Are Anti-Oxidants? And Why are They Good for You

Antioxidants are molecules that inhibit the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Free radicals are unstable atoms that can damage cells, causing illness and aging.

 Types of Antioxidants

1. Endogenous Antioxidants: Produced by the body.

   - Glutathione

   - Superoxide dismutase (SOD)

   - Catalase

2. Exogenous Antioxidants: Obtained from the diet.

   - Vitamin C (ascorbic acid)

   - Vitamin E (tocopherol)

   - Beta-carotene

   - Selenium

   - Flavonoids and polyphenols (found in fruits, vegetables, tea, wine)

 Benefits of Antioxidants

1. Reducing Oxidative Stress: Antioxidants neutralize free radicals, reducing oxidative stress and potentially lowering the risk of chronic diseases such as heart disease, cancer, and neurodegenerative disorders.

2. Anti-Inflammatory Properties: Some antioxidants have anti-inflammatory effects, helping to reduce inflammation in the body, which is linked to many chronic diseases.

3. Skin Health: Antioxidants like vitamins C and E protect the skin from damage caused by ultraviolet (UV) radiation and pollution, potentially reducing signs of aging such as wrinkles and sunspots.

4. Immune Support: Antioxidants support the immune system by protecting cells from damage, which can help the body fight off infections and diseases more effectively.

5. Eye Health: Antioxidants like lutein and zeaxanthin are beneficial for eye health and can help prevent age-related macular degeneration and cataracts.

6. Brain Health: Antioxidants may protect the brain from oxidative damage, potentially reducing the risk of cognitive decline and diseases like Alzheimer's and Parkinson's.

 Sources of Antioxidants

- Fruits: Berries (blueberries, strawberries), oranges, apples, grapes

- Vegetables: Spinach, kale, broccoli, carrots

- Nuts and Seeds: Almonds, sunflower seeds

- Beverages: Green tea, coffee, red wine

- Other: Dark chocolate, herbs (such as turmeric and ginger)

Incorporating a variety of antioxidant-rich foods into your diet can help maintain optimal health and protect against various diseases.
