Antioxidants Explained in Simple Terms
What Are Antioxidants?
Antioxidants are molecules that can help your body fight off harmful free radicals, which have been linked to health conditions like diabetes and cancer. They’re found in many plant-based foods. Vitamin E and C are examples.
How Do Antioxidants Work?
Antioxidants are essential for the survival of all living things. Your body generates its own antioxidants, such as the cellular antioxidant glutathione. Plants and animals, as well as all other forms of life, have their own defenses against free radicals and oxidative damage.
Free Radicals and Oxidative Stress
Free radicals are constantly being formed in your body. Without antioxidants, free radicals would cause serious harm very quickly, eventually resulting in death. However, free radicals also serve important functions that are essential for health. For example, your immune cells use free radicals to fight infections.
The Importance of Antioxidants
Antioxidants are essential for optimal health. They help protect your cells from damage caused by free radicals. Prolonged oxidative stress leads to an increased risk of negative health outcomes, such as cardiovascular disease and certain types of cancer.
Antioxidant Categories
Antioxidants can be categorized as either water- or fat-soluble. Water-soluble antioxidants perform their actions in the fluid inside and outside cells, whereas fat-soluble ones act primarily in cell membranes.
Important Dietary Antioxidants
Important dietary antioxidants include:
- Vitamin C: This water-soluble antioxidant is an essential dietary nutrient.
- Vitamin E: This fat-soluble antioxidant plays a critical role in protecting cell membranes against oxidative damage.
- Flavonoids: This group of plant antioxidants has many beneficial health effects.
The Antioxidant Paradox
Dietary intake of antioxidants is essential for optimal health, but more is not always better. Excessive intake of isolated antioxidants can have toxic effects and may even promote rather than prevent oxidative damage.
Conclusion
Adequate antioxidant intake is essential to a healthy diet, although some studies suggest that high-dose supplements may be harmful. The best strategy is to get your daily dose of antioxidants from healthy plant foods, such as fruits and vegetables.
