Who specializes in the science of diet and nutrition?

The correct choice is Dietitian (RD) because registered dietitians (RDs) are specifically trained professionals who are experts in the science of diet and nutrition. They have completed extensive education and clinical training, often holding a bachelor's degree or higher in dietetics or nutrition and passing a national examination. RDs are qualified to assess nutritional needs, develop meal plans, and provide education on nutrition-related issues.

The role of a dietitian also extends to working with patients to manage dietary needs regarding health conditions, ensuring individuals receive proper nutritional support to promote overall health and well-being. Their expertise is grounded in evidence-based research, making them the go-to professionals for tailored dietary advice and interventions.

While nutritionists also focus on diet and nutrition, the term is not as strictly regulated, and individuals calling themselves nutritionists may not have the same level of formal education or credentials as a registered dietitian. Food scientists study food and its properties but do not necessarily specialize in diet for individuals. Public health educators may promote health awareness and healthy eating practices but are not specifically trained in nutritional science as a dietitian is.
