We've all heard the word "Dietitian" somewhere, right? Maybe in a hospital, on TV when an athlete talks about his diet, or from a friend who's trying to lose weight. But many people don't have a clear idea of who exactly a Dietitian is, what they do, and how they help our health. Some people think that a Dietitian and a Nutritionist are not two people, but one. So today, let's talk about this exactly, very simply.
Who is a Registered Dietitian?
Simply put, a Registered Dietitian is a qualified health professional who specializes in food and nutrition. Just as a doctor specializes in diseases, a Dietitian specializes in food and nutrition. They use this knowledge to help people improve their health through food.
There's an easy way to tell if someone is a qualified registered dietitian. That's by looking at the letters after their name.
- RD - That stands for Registered Dietitian.
- RDN - That stands for Registered Dietitian Nutritionist.
Both of these methods refer to the same qualification. In some countries, a special license is required to practice this profession. Such people are also referred to as LD (Licensed Dietitian) after their names. These qualifications show that they are not just people who give advice about food, but have received special education and training for that purpose.
How can a dietitian help you?
There are many different types of help you can get from a dietitian. It depends on your needs. Let's look at a few scenarios.
In a hospital setting
Imagine that one of your relatives has undergone a major surgery or is being treated in the hospital for a serious illness. In times like these , proper nutrition is essential for a speedy recovery. That's where the role of a dietitian in the hospital comes into play.
They consider everything from the patient's condition, age, and treatment to decide what nutrition the patient needs. They also decide how to provide that nutrition.
- Do you feed by mouth?
- Is it given through a tube (`Tube feeding`)?
- Or is it given through an intravenous (IV) saline solution?
It is their responsibility to decide all of this and make the maximum contribution to the patient's healing process through nutrition.
Meet in person and get advice
You can also meet with a dietitian in person and ask for help in creating your nutrition plan. Here are some reasons why many people find a dietitian this way:
- Manage a medical condition: If you have a condition like diabetes, high cholesterol, high blood pressure, or kidney disease, it's important to control your diet. But it can be hard to know where to start, what to eat, and what not to eat. A dietitian can help you create a personalized meal plan that's right for you and your condition.
- Manage your weight: If you need professional advice on how to lose weight healthily, or if you are underweight, how to gain weight healthily, a dietitian is the best person to turn to.
- Improve athletic performance: Proper nutrition is essential for an athlete to maximize their performance. They can plan what to eat during training, before and after competitions.
- Nutrition during pregnancy: Get advice on the proper nutrition needed by a pregnant mother and her unborn baby.
- Food Allergies: For someone who is allergic to certain foods, prepare a meal that avoids those foods and provides the necessary nutrition.
But remember one thing. If you have a medical condition, you should first talk to your doctor and only go see a nutritionist based on his or her advice.
Different types of dietitians and areas of expertise
Just as there are different types and areas of expertise among doctors, such as pediatrics and cardiology, there are also different types and areas of expertise among dietitians. Let's take a look at this table.
| Nutritionist Type | The task is simple. |
|---|---|
| Clinical Dietitians | People who work in healthcare institutions like hospitals and nursing homes monitor the nutritional needs of patients receiving treatment there. |
| Community Dietitians | Those who work to promote health and wellness in society in general. They work in government agencies, non-profit organizations, or corporate wellness programs. |
| Management Dietitians | Oversees food planning, menu development, and food service programs in institutions such as prisons, schools, and large restaurant chains. |
| Consultant Dietitians | Those who work privately create meal plans that suit the specific needs and goals of their clients. |
| Research Dietitians | People who research how food affects people. For example, they might study a single topic in depth, such as food allergies. |
Areas where a dietitian can specialize
In addition, a dietitian can also specialize in a specific area.
- Geriatric Nutrition: Experts in the nutrition needs of our aging parents and grandparents. They create meal plans that help prevent and treat conditions like osteoporosis, which is common with aging.
- Pediatric Nutrition: Develops nutritional plans necessary for the normal growth and development of children.
- Pediatric Critical Care Nutrition: Works with healthcare teams caring for children treated in intensive care units.
- Obesity and Weight Management: Provides support to those trying to manage their weight to prevent or treat obesity.
- Sports Nutrition: Specialists in the nutrition needed by athletes and those in high-performance professions such as the police and military.
- Renal Nutrition: Special diet plans are created for patients with Chronic Kidney Disease (CKD) and kidney failure.
- Oncology Nutrition: Those who have expertise in the nutritional needs of patients undergoing treatment or recovering from cancer.
- Eating Disorders: Focuses on nutritional rehabilitation for people with eating disorders.
- Diabetes Nutrition and Care: Helps people prevent and manage diabetes. Some people even earn a special qualification called ``Certified Diabetes Care and Education Specialist (CDCES)``.
What is the difference between a Dietitian and a Nutritionist?
This is a point of confusion for many. While we in Sri Lanka hear both these words as the same, there is a big difference between the two.
"Registered Dietitian (RD)" is a legally protected title. This means that only someone who has completed a bachelor's and master's degree from a recognized university, completed over 1,000 hours of supervised training, passed a nationally recognized exam, and is registered can use this title. They are authorized to provide medical nutrition therapy for medical conditions.
On the other hand, the term "Nutritionist" is not very regulated. Some Nutritionists may be highly qualified. However, sometimes, even someone who has taken a short course in nutrition can call themselves a Nutritionist. They are usually not legally allowed to prescribe diets as a treatment for medical conditions.
Simply put, every Registered Dietitian is a Nutritionist, but not every Nutritionist is a Registered Dietitian.
Therefore, if you are seeking nutritional advice for a medical condition, it is safest and most accurate to see someone who is qualified as an RD or RDN .
Nutrition is important to all of us, everywhere. A dietitian is a qualified professional who can give us the right guidance on these important matters. Sometimes they work directly with us. Other times they are behind the scenes, planning meals for a patient in a hospital. However, they play a very important role in providing people with the nutrition they need to live a healthy life.
