nutritionist

A nutritionist is a health professional who specializes in the science of nutrition and its role in health and disease. Nutritionists advise individuals and groups on food choices, nutrient intake, and dietary patterns to improve health, prevent illness, or support medical treatment. They may work with athletes, patients with chronic conditions, or communities seeking to promote healthier eating habits.

Education and credentials for nutritionists vary by country and jurisdiction. Many complete degrees in nutrition, dietetics, or related fields at the undergraduate or graduate level. In some regions, the title is protected by law and practitioners must be licensed, registered, or certified; in others, the title is used without statutory regulation. Examples of widely recognized credentials include registered dietitian nutritionist (RDN) in some countries, though specific requirements differ.

Scope of practice typically includes assessing nutritional needs, designing individualized meal plans, providing counseling, and monitoring progress. Nutritionists may specialize in areas such as weight management, sports nutrition, pediatric or geriatric nutrition, diabetes, or cardiovascular health. They work in diverse settings, including clinics, hospitals, schools, public health programs, research institutions, wellness programs, and private practice.

Professional standards emphasize evidence-based guidance, ethical conduct, and collaboration with other health professionals. Some regions regulate practice to ensure safety and quality, while others rely on voluntary certification. Consumers should verify credentials and scope of practice when seeking nutrition-related services.
