They are known for their antioxidant, anti-inflammatory, and anti-cancer properties. Phytochemicals are abundant in fruits, vegetables, whole grains, legumes, herbs, and spices. Consuming a diet rich in phytochemicals has been associated with a reduced risk of chronic diseases such as heart disease, cancer, and diabetes.
