Antioxidants

Definition

Antioxidants are substances that help protect your body from damage caused by harmful molecules called free radicals.

Scientific / Technical Definition

Antioxidants are molecules that prevent the oxidation of other molecules in the body. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves.

Benefits

• Protects cells from damage by free radicals
• May lower the risk of certain chronic diseases such as heart disease and cancer
• Supports natural aging processes
• Boosts immune function
• Helps maintain skin health

Examples

• Vitamin C (found in citrus fruits like oranges)
• Vitamin E (found in nuts and seeds)
• Beta-carotene (found in carrots and sweet potatoes)
• Flavonoids (found in berries and green tea)
• Selenium (found in Brazil nuts and seafood)

Additional Information

• effects: Antioxidants scavenge free radicals from the body's cells, and prevent or reduce the damage caused by oxidation reactions. This helps maintain the integrity and function of vital biological structures.
