Nutrition research is the scientific study of how food and nutrients affect health, growth, and development. It explores the relationship between diet and various health outcomes, such as obesity, heart disease, and diabetes. Researchers often conduct experiments, surveys, and clinical trials to gather data on dietary patterns and their effects on the body. The findings from nutrition research help inform public health guidelines and dietary recommendations. Organizations like the World Health Organization and U.S. Department of Agriculture use this information to promote healthy eating habits and improve overall health in populations. This research is essential for understanding how to prevent nutrition-related diseases.
