Functional Foods: The Future of Nutrition and Disease Prevention
As healthcare continues to shift from treating illness to preventing it, nutrition is playing a more important role than ever. One of the most exciting developments in this area is the growing interest in functional foods, foods that provide health benefits beyond basic nutrition. These foods contain naturally occurring or added compounds that may help improve overall well-being and reduce the risk of chronic diseases.
With increasing awareness of the connection between diet and long-term health, functional foods are emerging as a key component of modern preventive healthcare and personalized nutrition.
