(What do) Dietitians Do?

A registered dietitian is an extremely diverse profession. When you think of it, food and nutrition are tied into so many things in our lives and directly affects our health and illnesses. We are the nutrition and dietetics professionals with a proper scientific education in both theory and practice. Our title "dietitian" is in most countries protected and only people with the proper training are allowed to use it. 

I find that there is a lack of knowledge about what dietitians do. This is why the series "Dietitians Do" was created. It is work in progress so check back often.

Enjoy the reading and do not hesitate to contact me if you have questions or comments! 



Dietitian in ICU (intensive care unit)

As a clinical dietitian I began every day in the ICU. At 8 in the morning I had read up on new ICU patients and overnight updates on existing ones and was ready for interdisciplinary rounds. This means the head ICU physician together with nurses, speech therapists, physiotherapists, dietitians and other staff went through every patient’s current status and plan forward. This happens every day. There may also be changes throughout the day so being paged later the same day by ICU for a patient happened frequently as something had changed. Read more.... 


Dietitian providing nutrition support (when you cannot eat via your mouth)

Nutrition support may sound like something dietitians are doing all the time. However, nutrition support in the dietitian world really refers to nutrition provided to a patient who is unable to eat via their mouth. This happens more often than you may think. 


There are two main types of nutrition support. The first choice would always be what is called enteral nutrition (also called tube feeding). This is for the patient who has a functioning gastrointestinal system (stomach and intestines) but for some reason is unable to use their mouth to eat. Read more...

Dietitian playing a crucial role for your kidneys

Healthy kidneys filter about 118 milliliters of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to your bladder. Your kidneys are also producing hormones that helps with:


  • controlling your blood pressure

  • making red blood cells 

  • keeping your bones healthy


The kidneys also remove acid produced by cells in your body and maintain a balance of water, salts, and minerals, such as sodium, calcium, phosphorus, and potassium, in your blood. Read more...
