Nutraceuticals provide health benefits and can be used to prevent and treat diseases. They include fatty acids, polyphenols, probiotics, phytoestrogens, carotenoids, dietary fiber, herbs, and phytochemicals. Many plant-based foods and nutrients have anti-inflammatory, antioxidant, and anticancer properties. Consuming a diet rich in nutraceuticals from foods like fruits, vegetables, whole grains, and herbs can help maximize health and reduce disease risk when combined with exercise and stress reduction.
