What are antioxidants and why are they important?

Antioxidants are molecules that play a crucial role in protecting cells from oxidative damage caused by oxygen free radicals, which are produced by metabolic processes in our bodies and external sources, such as pollution, radiation and chemicals.

The process of oxidative damage occurs when free radicals interact with and damage important cellular components like DNA, proteins and lipids. This damage can lead to various health problems and is linked to several chronic diseases, including cardiovascular diseases, cancer, diabetes and neurodegenerative disorders.

Antioxidants neutralize free radicals by donating an electron, stabilizing them, and preventing further damage to the cells. Some well-known antioxidants include vitamins C and E, beta-carotene, selenium, and various phytochemicals found in fruits, vegetables and other plant-based foods.

Here's why antioxidants are important for the body:

• Protection of the cells from oxidative damage, reducing the risk of DNA mutations and resulting cancers
• Reduced risk of chronic diseases, including heart disease, cancer, and diabetes
• Immune system support due to decreased oxidative damage in the cells and DNA
• Skin health, as antioxidants protect the skin from UV damage that could cause DNA mutations and contribute to aging
• Improved cognitive function and reduced risk of neurodegenerative diseases like Alzheimer's and Parkinson's

Where can you find antioxidants?

Antioxidants are abundant in certain types of foods, namely fruits and vegetables. To consume an adequate amount of antioxidants in your diet, include a wide range of different fruits and veggies, including apples, bananas, berries, melons, green leafy vegetables, carrots, peppers, beets and potatoes.
