An antioxidant is a molecule that helps protect the body from oxidative stress and free radical damage. Antioxidants neutralize harmful molecules called free radicals, which can cause cell damage, aging, and chronic diseases like cancer, heart disease, and neurodegenerative disorders.
Explanation of How Antioxidants Work
Antioxidants act as the body’s defense system against oxidative stress, which occurs when free radicals outnumber antioxidants.
What Are Free Radicals?
- Free radicals are unstable molecules that form due to normal metabolism, pollution, UV rays, smoking, and stress.
- They damage DNA, proteins, and cells, leading to aging and disease.
How Antioxidants Neutralize Free Radicals
- Antioxidants donate an electron to free radicals, stabilizing them and preventing cell damage.
- This process helps reduce inflammation, protect tissues, and slow aging.
Types of Antioxidants & Their Benefits
| Antioxidant Type | Function | Food Sources |
|---|---|---|
| Vitamin C | Protects skin & boosts immunity | Citrus fruits 🍊, bell peppers 🫑, strawberries 🍓 |
| Vitamin E | Supports heart health & skin repair | Nuts 🥜, seeds, spinach 🥬 |
| Beta-Carotene | Protects vision & skin | Carrots 🥕, sweet potatoes 🍠, mangoes 🥭 |
| Polyphenols | Reduces inflammation & supports brain health | Berries 🍓, tea 🍵, dark chocolate 🍫 |

✅ Use Spices & Herbs – Turmeric, cinnamon, and oregano are powerful antioxidants.
✅ Choose Dark Chocolate (70%+ Cocoa) – Contains flavonoids that protect the brain.
✅ Reduce Processed & Fried Foods – These increase oxidative stress.
Final Takeaway
- Antioxidants protect the body from free radicals and oxidative stress, reducing aging and disease risk.
- They are found in fruits, vegetables, nuts, tea, and dark chocolate.
- A diet rich in antioxidants supports brain function, heart health, and immune strength.
- Eating a variety of antioxidant-rich foods daily enhances overall well-being.
