Antioxidants are substances that help protect your cells from damage caused by free radicals—unstable molecules produced by your body during normal processes like metabolism, or from external sources like pollution, cigarette smoke, and radiation.
What Free Radicals Do:
-
Free radicals are highly reactive and can damage cells, proteins, and DNA.
-
This process is called oxidative stress, which contributes to aging and many chronic diseases (e.g., cancer, heart disease, Alzheimer’s).
What Antioxidants Do:
-
Antioxidants neutralize free radicals, preventing or reducing damage.
-
They help reduce inflammation, support immune health, and slow the aging process.
Common Antioxidants:
-
Vitamin C – found in citrus fruits, berries, peppers
-
Vitamin E – found in nuts, seeds, and vegetable oils
-
Beta-carotene – found in carrots, sweet potatoes, and leafy greens
-
Selenium – found in Brazil nuts, seafood, and grains
