Consuming antioxidants in your diet is significant because they help combat oxidative stress and reduce cellular damage caused by free radicals. This can lower the risk of chronic diseases such as cancer, heart disease, and neurodegenerative disorders. Fruits, vegetables, nuts, and whole grains are rich sources of antioxidants. Including these foods in your daily intake can support overall health, improve immune function, and promote a longer, healthier life by mitigating the impact of oxidative stress on the body.
