Antioxidants: An Overview
Antioxidants are molecules that inhibit oxidation, a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. They are crucial for maintaining cellular health and preventing oxidative stress.
Oxidative Stress Explained
Oxidative stress occurs when there's an imbalance between free radicals and antioxidants in your body. This imbalance can lead to cell and tissue damage, contributing to aging and diseases like cancer and heart disease.
Endogenous vs Exogenous
The body produces its own antioxidants, called endogenous antioxidants. Exogenous antioxidants, on the other hand, come from the diet and include vitamins C and E, selenium, and carotenoids.
Antioxidants and Longevity
Studies suggest a link between a diet rich in antioxidants and increased lifespan. Antioxidants may slow aging by protecting cells from damage, enhancing repair mechanisms, and influencing gene expression related to longevity.
Mitochondrial Protection
Mitochondria, the cell's powerhouses, are susceptible to oxidative damage. Antioxidants like Coenzyme Q10 help safeguard these structures, ensuring energy production continues efficiently, which is vital for cell survival and function.
Antioxidants in Skin Care
Topical antioxidants protect the skin from environmental damage, reduce inflammation, and can prevent signs of aging. Ingredients like vitamin C, vitamin E, and ferulic acid are commonly found in skincare products.
Dietary Sources
A balanced diet rich in fruits, vegetables, nuts, and whole grains provides a variety of antioxidants. Berries, green leafy vegetables, and dark chocolate are especially potent sources. Supplementation should be considered after consulting with a healthcare professional.
