Dietitians vs. Nutritionists - Who Should You Trust?
Would you know who to trust when it comes to nutrition advice?
You might trust what you read or hear, but do you know if the source is qualified and registered?
As a nutrition professional, I see so much misinformation out there - and it’s frustrating!
For busy professionals and endurance athletes, understanding the difference between a clinical dietitian and a nutritionist is essential.
Dietitians are highly trained healthcare professionals who must be registered with the Health and Care Professions Council (HCPC) in the UK. They are legally regulated and qualified to work in various settings, including hospitals, community services, and private practice. Dietitians use evidence-based approaches to assess, diagnose, and treat dietary and nutritional problems.
In contrast, the title "nutritionist" is not legally protected, meaning anyone can use it, regardless of their qualifications.
While some nutritionists are highly trained and registered with organisations like the Association for Nutrition (AfN), they cannot work with acutely ill patients without supervision from a dietitian. Many nutritionists in and outside of sports are highly acclaimed, but to be sure of their credibility, always check their registration.
The Risks of Unqualified Advice
Some nutritionists and nutritional therapists may not have the same level of training or commitment to evidence-based practice. Following unqualified advice can lead to poor outcomes, from underperformance in sports to serious health risks.
As a business professional or athlete, you wouldn’t trust your finances or training to someone without the proper credentials – so why take that risk with your nutrition?

The Evolution of Dietetics - From the 1960s to Our Screens Today
The field of dietetics has evolved significantly since the British Dietetic Association (BDA) was founded in 1936. In fact, the first dietetic department was established at the Royal Infirmary of Edinburgh.
Early dietary interventions were sometimes extreme, from “spleen diets” (pulp scraped from the fibrous part of the spleen, tossed in oatmeal, and fried) to strict calculations of fats and carbohydrates for diabetes management. The approach to nutrition in hospitals was highly regimented, from making beef tea to boiling carrots!
In the 1960s, dietitians primarily worked in hospitals, focusing on meal planning and nutrition for patients with specific medical conditions like diabetes or heart disease. Their work was crucial in managing patient health during hospital stays, with a strong emphasis on therapeutic diets tailored to individual needs
(…more on this coming soon as I delve into my own recent experience of hospital food!).
Today, dietitians have expanded their influence far beyond hospitals. They are involved in public health, community services, and media - including social media platforms.
The importance of nutrition is more widely recognised than ever before, with growing awareness of how what we eat affects not just our weight but also our overall health, performance, and longevity.
Modern dietitians appear on TV shows to educate the public about healthy eating - have you seen the UK television series Know Your S***: Inside Our Guts? This features dietitians providing expert advice on gut health and nutrition. These TV appearances help bring evidence-based dietary guidance to a broader audience, showcasing the vital role dietitians play in modern society.
There are also many individuals whose reach influences thousands of people through platforms like Instagram and TikTok.
While social media has great potential to spread nutrition advice quickly and widely, it’s important to consider whether the information is backed by science. Not all content creators have the necessary expertise, and misinformation can spread just as fast as the truth. Always check the credentials of those providing nutrition advice and ensure recommendations are evidence-based.
The phrase “food is medicine” is gaining traction, and for good reason.
Scientific research continues to highlight how diet plays a crucial role in preventing, managing, and even treating numerous illnesses, from heart disease to diabetes and beyond. A well-balanced, nutrient-rich diet can support immune function, enhance recovery, and improve overall well-being.
As a registered nutrition professional, I love seeing how the field has evolved.
We’ve come a long way, and the science behind nutrition continues to grow!

Making Informed Choices - Questions to Ask Your Nutrition Professional
Before working with a nutrition professional, ask yourself:
Do I know their qualifications?
Can I trust their advice?
How do I evaluate what I read or hear?
Choosing a nutrition professional requires careful consideration. Start by asking about their qualifications and whether they are registered with a professional body like the HCPC (for dietitians), the SENr (for sports nutritionists), or the AfN (for Nutritionists).
Dietitians are legally regulated and must adhere to strict professional standards, ensuring their advice is based on the latest scientific research. Nutritionists, especially those not registered with recognised bodies, may not have the same level of training or accountability.
Take a moment to reflect:
Have you ever followed nutrition advice that wasn’t backed by science?
Did it improve your performance and health, or did it lead to confusion and ineffective results?
In a world filled with misinformation, making informed choices about your nutrition is vital for optimising health and performance, whether in business or sports.
If you’re serious about making nutrition work for you, let’s cut through the noise together.
Your nutrition choices impact every aspect of your performance and well-being - so make them wisely!
