Health Makes More Healthy


The Role of Dietitians and Nutritionists

Eating right within the correct range of calories to maintain that svelte or lean figure you’ve worked out so hard for can be quite a challenge. With the blooming surge of fast-food outlets and unhealthy eating habits adopted by young urchins as early as five years of age, cases of obesity and diabetes along with other extensive health complications has been irrevocably on the rise within the past few decades. Of course, this is when healthcare intervention comes in – often in the form of a dietitian or nutritionist.

Both dietitians and nutritionists are professionals and are denoted as experts in eating habits and general nutrition. Holders of both professions often mete out their expertise in the form of nutrition-related advice with regards to healthcare, governmental, and private institutions. Dietitians generally require an academic qualification, however, and must either hold a Postgraduate Diploma or Masters in Dietetics, or even attain a Bachelor of Science in Dietetics to earn their practicing license. Nutritionists on the other hand, don’t require any professional qualifications and can be self-trained. Thus, all dietitians are nutritionists, but not all nutritionists are dietitians.

Various countries around the world regulate the dietitians and nutritionists in different ways, all with the objective of ensuring relevant and up-to-date practices that can aid their patients. Below are the government entities that make sure these objectives are met.
