Phytonutrients in plant-based foods play a vital role in promoting health and wellness. These bioactive compounds, found in fruits, vegetables, and whole grains, have antioxidant properties that help combat oxidative stress and inflammation. Specific phytonutrients, like flavonoids and carotenoids, can support immune function and reduce the risk of chronic diseases, including cancers and heart disease. Incorporating a variety of colorful plant-based foods ensures a wide range of phytonutrients, benefiting overall health and fitness.
