Much is known about the importance of eating among healthy habits. For this reason, it is interesting to implement tools such as medical nutritional therapy, with which diseases can be improved.

What is medical nutrition therapy?

Medical nutrition therapy (also known as TNM for short) is a type of specialized nutritional therapy. It is carried out by medical experts and nutritionists and adapts individually to each person.

The first reference and definition dates from 1994. The Academy of Nutrition and Dietetics of the United States defines it as a set of diagnostic services, therapy and nutritional counseling directed to the management of some diseases. This mention is also supported by other associations and accredited professionals.

Services must be led by a nutrition professional with an in-depth evaluation of each case. In addition, they last the duration that each situation requires, with regular visits or contacts.

Its application is not intended to replace the usual treatment of diseases. However, it is a valuable adjunct to medical and pharmaceutical therapies.

There are diets designed for specific pathological problems. Certain foods contribute to well-being in some patients with specific cases.

When is it recommended?

Medical nutrition therapy is a common treatment in countries such as the United States, Canada, Japan, New Zealand, and some parts of Europe. Sometimes it is provided by the public health system itself.

There are a number of certain conditions that can improve with its application. Affected people are evaluated by a nutritionist who is in charge of determining the need or not for its implementation.

In the hospital setting, it is usually a doctor who requests this evaluation. And in the outpatient setting, it is each person’s own dietitians or doctors who can determine the need to implement NMT.

In some situations, medical nutritional therapy may be the first intervention applied. On other occasions it is combined with drug therapy. NMT is an integral component of the approach.



What are the bases of medical nutritional therapy?

The management of TNM is in charge of professional nutritionists in contact and collaboration with the doctor of each patient. From here, a nutritional evaluation is carried out based on scientific evidence guides and nutrition protocols. Therefore, access to the most advanced knowledge is guaranteed.

During the process, the work is carried out with the collaboration of the patient. Both set the objectives, the plan to follow and the necessary monitoring. The type of diet, the prescribed guidelines and the duration are variable and always depend on each case and its evolution.

Unlike the usual nutritional advice, medical nutrition therapy is dedicated to specific health conditions and is very individual.
