Is there a cure for your illness through food? Let's learn about Medical Nutrition Therapy!
Table of Contents ▾
When you go to see a doctor, you must have heard that "it's better to control what you eat and drink a little," right? In fact, the diet we eat directly affects many of our diseases. But what exactly does this "controlling diet" mean? Some people think that it's just about cutting down on rice and stopping eating oil. But today we are going to talk about a deeper, more scientific method. It is called Medical Nutrition Therapy (MNT) . Simply put, this is a special diet plan created by a qualified professional that is tailored to your medical condition, body, and lifestyle.

Who should receive this medical nutrition therapy (MNT)?

This treatment method is especially important for those with long-term, or chronic, medical conditions. You should talk to your doctor and follow his or her recommendations before starting this treatment method. This is not just a diet plan, but part of a medical treatment. Just like we take pills for some diseases, in this method our "medicine" is the food we eat. Check out the table below to see what are the main medical conditions that can benefit from MNT.
Condition How MNT can help
Diabetes To control blood sugar levels and reduce complications.
Heart Disease Reduce cholesterol and blood pressure and maintain heart health.
Renal Disease A special diet plan to control kidney damage.
Obesity To lose weight healthily and maintain it.
Gastrointestinal Disorders To control symptoms such as stomach inflammation and gas.
Cancer To maintain body strength and nutrition during treatment.
Osteoporosis To provide nutrients that strengthen bones.

Diabetes and weight loss

Among these, let's talk about two examples in a little more detail.
  • Diabetes: If you have diabetes, MNT is your best bet. Along with the medication your doctor prescribes, following a personalized nutrition plan can help you control your blood glucose levels . This can help reduce many of the symptoms of diabetes, such as frequent urination and weight gain.
  • Weight Loss : Many people try different things to lose weight . But doing things without a scientific basis can harm the body. MNT is the best way to lose weight in a healthy and systematic way. If you are obese, your doctor may refer you to MNT. Because losing weight can save you from many other diseases such as high blood pressure , heart disease, liver disease , and infertility .

How does this MNT treatment work?

The process is very simple. But it is important to follow it exactly. 1. Visit your doctor: First, you should visit your primary care doctor and talk about your medical condition. If he or she decides that MNT is right for you, he or she will refer you to a qualified dietitian or nutritionist . 2. First meeting with the nutritionist: This is the most important step. During this meeting, which usually lasts about an hour, the nutritionist will ask you a few questions.
  • What kind of food do you currently eat? (The amount of rice you eat per day, the amount of sugar you put in your tea, the types of fruits you eat, etc.)
  • What is your lifestyle like? (What job do you do, do you exercise, what time do you sleep?)
  • Your medical records and medical history.
  • What are your hopes for this treatment? (Lose weight? Control sugar?)
3. A personalized plan: Using all this information, the nutritionist will create a nutritional plan that is tailored to you, not just you or me. It will also take into account your cultural preferences (for example, if you are a vegetarian, it will be tailored to your needs).
Remember, this is not a "no-food" list. This is a plan that guides you on "what to eat, how much to eat, and when to eat."
Often, you will be asked to keep a "food journal." This means writing down everything you eat and drink throughout the day. This will help both you and the nutritionist get a better understanding of your eating habits. 4. Follow-up appointments: After the first appointment, you will be asked to come back at regular intervals . At that time, your progress will be reviewed and any changes to the plan will be made if necessary. Your new lab results will also be reviewed to ensure that you are getting the nutrition you need.

What are the real benefits of this?

The benefits of MNT are not limited to weight loss. It's an investment for your entire life.
  • Disease control: The main benefit is that you can better control your chronic disease. This can help you avoid dangerous complications like diabetic neuropathy or heart disease that may develop in the future.
  • Increased energy and vitality: When you are properly nourished, the feeling of tiredness and drowsiness disappears, and you can work with energy throughout the day. Imagine, you used to have a hard time climbing stairs, but with this treatment, you can do it with ease.
  • Formation of healthy habits: With this process, you will also develop good habits without even realizing it.
  • I'm tempted to exercise.
  • When buying food from the store, we make a habit of choosing by reading the label and checking how much sugar, salt, and oil it contains.
  • Reduce fried or processed foods.
  • Instead of sugary drinks, get used to drinking the required amount of water per day.
These habits will not only protect your current health, but also your future health.

💡 Take-Home Message
