I was more thinkin out loud and of the UK. The qual you need to be a state dietitician is a 4 yr course called
BSc (Hons) Degree in Dietetics
If you pass it, you become a proper 'Dietician' and can work in a hospital and have your own office.
The course covers...
- Catering/Food Science/Food Skills
- Clinical Medicine/Pharmacology
- Communications/Educational Methods/Health Education
- Information Technology/Research Methods and Statistics
- Social Policy and Administration
Anyway I did a month in a hospital working with three different dieticians who were responsible for quite serious aspects of patients ancillary treatment.
One had total misunderstanding of food based pathogens, one would not believe omega 3 are found anywhere else then fish oils and all of them said protein powder / vitamins are dangerous etc. Plus they knew FUCK ALL about healthy eating, nutrition, dietetics etc.
Unless someone who was a dietician read up elsewhere or was clued up to the failings of their knowledge I'd not employ them. They used to suggest eating more margerine as a good way to gain weigh in malnourished people.
I agree there are good dieticians / nutritionists but there aren't many.
