Phytochemicals are diverse bioactive compounds found in plants that play a crucial role in nutrition. They contribute to health by acting as antioxidants, reducing the risk of chronic diseases such as heart disease and cancer. Phytochemicals can also enhance immune function and improve overall health by providing anti-inflammatory benefits. Since these compounds often work synergistically, a diet rich in a variety of colorful fruits and vegetables ensures a broad spectrum of phytochemicals, optimizing their positive impact on well-being.
