A plant-based diet, which focuses on whole foods derived from plants, can be very beneficial. This diet is rich in fiber, vitamins, minerals, and phytonutrients that can help reduce inflammation and support the immune system. Studies have shown that diets high in fruits, vegetables, and whole grains are associated with a lower risk of various cancers. However, it is essential to ensure that the diet is well-balanced and includes adequate protein and essential nutrients.
