What Are Antioxidants?
Antioxidants are naturally occurring compounds found in various foods and supplements that help protect the body from oxidative stress. Oxidative stress results from the imbalanced production of free radicals—unstable molecules that can damage cells and contribute to the aging process and the development of chronic diseases.
Sources of Antioxidants
Many fruits and vegetables are rich in antioxidants, including:
- Berries (blueberries, strawberries, raspberries)
- Green leafy vegetables (spinach, kale)
- Nuts and seeds (walnuts, sunflower seeds)
- Whole grains (oats, brown rice)
- Dark chocolate and green tea
Types of Antioxidants
There are several types of antioxidants, categorized into two main groups:
- Vitamin-based: Such as Vitamin C, Vitamin E, and beta-carotene.
- Phytonutrient-based: Including flavonoids, polyphenols, and carotenoids.
Health Benefits
Antioxidants play a crucial role in maintaining health by:
- Reducing inflammation
- Enhancing immune function
- Protecting against heart disease and cancer
- Promoting skin health
Incorporating a variety of antioxidant-rich foods into your diet can contribute significantly to overall wellness and longevity.
