Food is medicine, and nothing makes this more evident than when you eat a diet rich in antioxidants, which studies show lowers your risk of diseases, including heart disease and certain cancers. By eating antioxidant-rich foods you are protecting your body against free radicals and helping to slow aging, boost immunity, and contribute to overall health and wellbeing.

Antioxidants are substances that help protect the body from oxidative stress and prevent or minimize damage to the body caused by free radicals. They are most abundant in plant-based foods: Vegetables, fruits, legumes, nuts, and seeds.

Free radicals are compounds that can damage cells if they exceed the body's threshold or tolerance, and have been linked to inflammation caused by oxidation, including premature aging, diabetes, heart disease, and cancer. Similarly, oxidative stress can damage cells, proteins, DNA, all of which can lead to accelerated aging.
