How to use the Global Hub
Pick a country below for its full profile, or scroll to the comparison table to see all 24 side by side. Every profile follows the same structure, so you can compare like with like:
- Regulation and credentials. Which body registers or licenses dietitians, the credential they hold, and whether "dietitian" is a protected title in law.
- Professional association. The national body that sets practice standards, runs continuing education and speaks for the profession.
- Supplement regulation. The agency and framework that decide how vitamins, minerals, botanicals and other supplements reach the market.
- Published numbers. Workforce, register and market figures, each with a citation. Where no figure is published we say so.
- Strengths and opportunities. What makes each market attractive for practitioners and companies, and where the gaps are.
- Jobs. Where dietitians and nutritionists work in that country and what is driving demand.
- Suppliers, manufacturers and retailers. Notable companies headquartered in the country.
- Events. Congresses and trade shows with dates checked on the organiser's site.

What the 24 countries have in common
Three patterns hold almost everywhere. First, the title "dietitian" is protected far more often than "nutritionist". In the United Kingdom, for example, only people on the Health and Care Professions Council register may call themselves dietitians, while "nutritionist" is open, with a voluntary register for qualified practitioners. The same split shows up in Ireland, Canada and much of Europe. Our guide to dietitian vs nutritionist explains what that means in practice.
Second, demand is rising faster than the workforce. Overweight and obesity affect 2.6 billion adults worldwide[1], and diabetes affects 589 million adults aged 20 to 79[2]. In countries that publish projections, the profession is expected to grow: the US Bureau of Labor Statistics projects 8% job growth between 2025 and 2035[3].
Third, supplement regulation follows one of a few models. The United States treats supplements as a category of food under the Dietary Supplement Health and Education Act of 1994, with no pre-market approval for most products. Canada licenses them as natural health products. Australia lists most of them as complementary medicines with the Therapeutic Goods Administration. The European Union harmonises the basics through the Food Supplements Directive and leaves notification to member states, which is why Germany, France, Italy, Spain and the Netherlands each have their own procedure. In Asia, Japan, South Korea and China run functional-food systems in which health claims are approved or notified product by product. Our dietary supplements guide goes deeper.
Where the opportunities are
For practitioners, the clearest openings are in countries with ageing populations and expanding hospital and community services, in telehealth across borders where licensing allows it, and in the fast-growing field of medical weight management. Countries that recognise foreign qualifications through a defined route, such as the UK, Ireland, Canada, Australia, New Zealand and the Gulf states, are the most realistic destinations for internationally trained dietitians. Each country page explains the route.
For companies, growth markets combine a large middle class, rising lifestyle disease and a clear registration pathway. India, China, Southeast Asia, the Gulf and Latin America all fit, though each has its own paperwork. Mature markets such as the United States, Western Europe, Japan and Australia offer scale and premium pricing but demand strong evidence and strict compliance.

Frequently asked questions
Which country has the most dietitians?
Among countries that publish counts, the United States has the largest credentialed workforce, with 112,446 registered dietitians and registered dietitian nutritionists on the Commission on Dietetic Registration register[4]. Many countries do not publish a national count, so a full worldwide ranking is not possible.
In which countries is "dietitian" a protected title?
It is protected in law in, among others, the UK, Ireland, Canada, New Zealand, the Netherlands, France, Italy, Spain, Switzerland, South Africa, the Philippines, Japan, South Korea, Brazil and Malaysia, and practice requires a licence in the US states that license dietitians and in the Gulf. Each country page gives the detail.
Can a dietitian trained in one country work in another?
Usually, but not automatically. Most regulators assess foreign qualifications and may require exams, supervised practice or language tests before registration. Routes are well established in the UK, Ireland, Canada, Australia, New Zealand and the Gulf states. Check the country page and the regulator's own guidance before you move.
How often is the Global Hub updated?
Country pages are reviewed when a regulator, association or statistics office publishes new figures, and at least once a year. The date each source was published or updated appears in its citation.
Why do some countries show "not published"?
Because we only print numbers we have read on the publisher's own page. If a regulator or association does not publish a workforce or market figure, we say so rather than estimating one.
