nutritionists

A nutritionist is a health professional who studies the relationship between diet, nutrition, and health. They assess clients' dietary intake and health status, provide evidence-based guidance on eating patterns, weight management, and disease prevention, and help develop individualized meal plans. Nutritionists work in clinical settings, community programs, schools, research, media, and private practice. They may specialize in areas such as clinical nutrition, public health nutrition, sports nutrition, or food systems and policy.

Education and regulation: Qualifications vary by country. Many places require a bachelor's or master’s degree in nutrition, dietetics, or a related field. In some jurisdictions the title nutritionist is not legally protected, allowing practice without a specific credential; in others, regulated titles require registration or licensure. Dietitians or registered dietitians are regulated professionals in many countries and typically complete supervised practice and a national exam. Additional certifications, such as CNS or other specialty credentials, may indicate advanced expertise.

Practice and scope: Nutritionists base guidance on current evidence, tailor advice to individual needs, and emphasize dietary patterns over single nutrients. They may work with patients with chronic diseases, allergies, or intolerances, and collaborate with physicians, nurses, and other health professionals. They contribute to education, program development, policy, and research, and may engage in public health initiatives. Ethical practice includes client confidentiality, informed consent, and ongoing professional education.
