What conditions treated by a Nutritionist? | Nutrition


What is a nutritionist?

In some countries, people may translate their title as “nutritionist” instead of “dietitian”, although their educational background is similar to that of a dietitian. In the United States, the title “Nutritionist” includes a wide range of sources and trained people in nutrition. In more than a dozen states, a person must have certain qualifications before being called a nutritionist. Also, accredited certifications award titles such as certified nutrition specialist.

In most states, holders of these certifications have the authority to practice medical nutrition therapy and other aspects of nutritional care. In many states, such as Alaska, Florida, Illinois, Maryland, Massachusetts, and Pennsylvania, RDs and CNSs have a single state license, commonly known as a licensed dietitian nutritionist license (LDN). In states that do not regulate the use of the term, anyone interested in food or nutrition calls themselves nutritionists. These people can apply their interest in nutrition to anything from running a food blog to working with clients.

However, since nonessential nutritionists generally do not have the experience and training for medical nutrition therapy and nutritional counselling, it is detrimental to follow their advice (9 Trusted source). Before consulting a nutritionist, you can check to see if your state regulates who can use this title.

What does a nutritionist do?

The nutritionist is an expert in the use of food and nutrition to promote health and manage the disease. These experts advise people on what to eat for a healthy lifestyle or to achieve a specific health-related goal. Many nutritionists work in hospitals, nursing homes, long-term care facilities, or doctor’s offices.

The term nutritionist is out of control, so technically, even without formal training, licensing, or certification, anyone can call themselves a nutritionist. RDN (Terms are interchangeable) has a specific meaning for registered dietitian or dietitian nutritionist, identified by RD after the name.


While nutrition is a specialized area with a wide range of real-world applications, two main focus centres introduce nutritionists to the general public.

Clinical nutrition

Clinical nutritionists work in clinical settings, often with inpatients and/or patients, as well as with their families, evaluating, designing, and implementing dietary strategies and nutritional therapies. Often the goal is to address a specific medical problem, such as hypertension, diabetes, or esophagitis, and clinical nutritionists are also asked to develop a plan of action in situations where a therapeutic protocol such as chemotherapy affects the patient’s overall diet to create a specific diet.

Community nutrition

Schools, community health clinics and recreation centres, federal, state, and local government agencies, and health management agencies (HMOs) are some of the places you can find nutritionists and dietitians who work in this capacity. Often in these settings, specific subgroups (eg, children, the elderly, families at risk) and their specific needs are directed to programs designed to address specific nutritional problems.

For example, when the U.S. Department of Agriculture and Health and Human Services released revised dietary guidelines based on the most recent scientific data, it was the job of community nutritionists and dietitians to explain the implications, educate the public, and implement action plans. Reaching new goals.

Procedural skill

The nutritionist often works as part of a multidisciplinary healthcare team that includes doctors, social workers, nurses, and home health care providers to help optimize treatment for everything from allergies and food intolerances and eating disorders to gastrointestinal disorders and problems of weight.

To that end, nutritionists typically do the following:

  • Assess the nutritional and health needs of patients and clients.
  • Counselling patients on nutritional issues and healthy eating habits.
  • Develop food and nutrition plans taking into account the preferences and budgets of the client.
  • Evaluate the effects of meal plans and change plans as needed
  • Continue or contribute to the latest research on food and nutrition. They need to understand scientific studies and translate nutrition into practical eating advice.

Sports dietitians are often hired to develop nutritional and fluid programs that are tailored for individual athletes or teams.

These professionals design, implement and maintain safe and effective nutrition strategies to promote the living standards and health of the elderly. At a time when nutrition is being increasingly recognized as an important aspect of healthy aging and disease management, these professionals have the “must-have” expertise of the senior network.

Kidney or nephrology nutritionist

Diet therapy is important for patients with chronic kidney disease (CKD), and those with knowledge of specific dietary requirements must evaluate and administer personalized medical nutrition therapy (NTM) for people with kidney disease. According to the National Institutes of Diabetes and Digestive and Kidney Diseases, TMN can slow the progression of CKD, prevent or treat problems such as malnutrition, and improve quality of life. Additionally, MNT can reduce healthcare costs.
