Medical nutrition therapy (MNT) is the application of nutrition science in the treatment or management of diseases. Such treatment often involves personalized dietary interventions for diseases like diabetes or cardiovascular disease, as well as obesity or malnutrition.
In the U.S., there is no strict number of hours a medical student is required to spend on nutrition, and studies have shown that they spend only 4-5 hours over four years learning about nutrition. The field of nutrition and dietetics is very specialized in covering that gap and meeting the need for qualified medical nutrition therapy.
As chronic disease trends rise and a growing focus on preventive health intensifies, the demand for nutrition professionals trained in MNT is steadily increasing. Arkansas State University (A-State) offers an online Bachelor of Science (B.S.) in Nutrition and Dietetics program that prepares you for a career in nutrition and dietetics and lays the groundwork for a master’s degree, the minimum requirement to sit for the credentialing exam to become a registered dietitian/nutritionist (RDN).
Medical Nutrition Therapy Definition and Purpose
Healthy eating habits have been proven to reduce the risk of many health conditions, but it’s not always easy to know how to adopt them. There is conflicting information about which foods are best for which purposes, underscoring the importance of nutrition education in helping people identify and eat the foods they need most when dealing with medical conditions.
Medical nutrition therapy is used to create personalized, nutrition-based treatment plans for a variety of specific conditions. In addition to appropriate choices for each chronic health challenge, specific nutrition therapy also covers the creation of medically tailored meals provided after surgery or following any medical event and during the convalescence period.
This differs from general healthy eating guidelines and is a personalized treatment plan, often covered by insurance. Beyond individual care, nutrition professionals also address community nutrition needs, working to improve food access and health outcomes at a population level. MNT for diabetes and kidney disease, as well as kidney transplant recipients within 36 months of their procedure, is typically covered by Medicare Part B Private insurance plans may cover MNT for a broader range of chronic conditions, such as heart disease and obesity, though coverage varies by plan.
What Common Conditions Are Treated With Medical Nutrition Therapy?
MNT is adapted to each individual and specific condition. For example, a patient with diabetes needs steady blood sugar management, which involves combining certain carbohydrates with protein, fat and fiber to slow the absorption of sugar. It may also involve weight or activity targets and must be coordinated with any medications the patient is taking.
Heart disease, high blood pressure or high cholesterol require a specific diet to help lower blood pressure, improve lipid profiles, reduce inflammation and support heart-healthy habits that aren’t overly restrictive. An MNT plan for kidney disease prioritizes adequate energy and calories while monitoring protein-energy issues, while a plan for cancer treatment focuses on treating and easing the side effects of the medication.
Treatment for eating disorders combines intervention and helps rebuild a normalized eating rhythm. Restoring nutritional health is often combined with psychological care.
Gastrointestinal disorders like IBS, Celiac disease or GERD require specific modifications to target symptoms directly. The goal is to heal the gut lining, prevent deficiencies and create a sustainable routine tailored to the individual triggers and tolerances.
How Does Medical Nutrition Therapy Work?
The Nutrition Care Process (NCP) for providing high-quality nutrition care consists of four steps: assessment, diagnosis, intervention, and monitoring and evaluation. Starting with the assessment, the patient’s history, test results, eating habits, lifestyle and nutritional status are collected. Based on that data, a diagnosis is made to name the specific problem.
After identifying the problem using the assessment information, an intervention program is designed to address the root cause and alleviate the signs and symptoms of the diagnosis. Monitoring and evaluation is the final step in the process to assess the patient’s progression and identify any needed modifications. Not all patients get the same care. The NCP is a framework for creating individualized care.
Who Provides Medical Nutrition Therapy?
MNT is delivered by RDNs with specialized clinical training. As of January 1, 2024, this certification requires a master’s degree to take the credentialing exam. The Commission on Dietetic Registration (CDR) administers the credentialing process.
Graduates of the B.S. in Nutrition and Dietetics online degree from Arkansas State University will be ServSafe certified and can pursue careers in nutrition in hospitals, retirement centers, government, school systems, food service and other areas. This program also prepares you for the coordinated master’s program to pursue RDN credentials.
