Antioxidants are compounds that are both naturally produced by the body and obtained through dietary sources, and they play a crucial role in protecting cells from damage. Oxidation is a chemical process that generates free radicals, unstable molecules that can harm the body when present in excessive amounts.

Want to power up your antioxidant intake? Just load up on a colorful variety of veggies, fruits, nuts, fungi, whole grains, legumes, herbs, spices, and even edible flowers! Here are some of the best antioxidant-packed foods, how they can boost your health, and some fun and easy ways to add them to your plate.

1. Apples

Research indicates that consuming apples and apple-based products can help protect against various diseases, including cancer, diabetes, and heart disease.
