Antioxidants in the diet benefit overall health by neutralizing free radicals, which can cause cellular damage and contribute to chronic diseases. Consuming foods rich in antioxidants, such as berries, dark leafy greens, and nuts, can strengthen the body's immune system and reduce inflammation. Regular intake of these compounds may lower the risk of diseases such as cancer, heart disease, and neurodegenerative disorders. Furthermore, antioxidants can support skin health and slow down the aging process by protecting cells from oxidative stress.
