See this is a great example, you've studied this topic extensively but don't seem to know the absolute basics of the industry.

"Not to mention nutritionists that are institutionally trained in dogma first, for licensure."

Nutritionist is not a protected title in the US or Australia, and actually requires no training whatsoever. It does require training and licensure to become a dietitian, because it's a clinically focused role. In many cases dietitians have prescribing privileges and are prescribing recipes for intravenous or tube fed nutrition.

That's why they're so heavily regulated my dude, I promise you clinically focused dietitians are not using the kind of industry research you're talking about. They are following protocols established over decades of clinical practice.

And if you're wondering why doctors are ill informed, it's because they're not typically trained in nutrition outside of the basics (outside of gastroentorology). Modern medical teams rely on a ton of support staff, one of those being clinical dietitians. Your doctor's job is to know who to consult.

So, because I displaced the term dietician with nutritionist conversationally you side step into a diatribe. You do realize that a lot of people have learning disabilities that make it difficult to remember specific terms in their place? It's kind of like a mental block in trying to remember. I have this when it comes to proper names all the time. It doesn't mean that I don't have an understanding of the conceptual base.

So, dieticians never suggested limiting cholesterol, and cutting out all saturated fat?

People mix up the title all the time, it's no big deal. I'm mostly focused on the fact that you were upset by the licensing requirement. I took that as evidence that you were not aware that dietitians are often a clinical facing role, with clinical responsibilities such as writing prescriptions.

Was I incorrect in that assumption? Or do you genuinely want to relax the licensure requirement for people who write IV prescriptions?

I'm not upset about the licensing requirement... I'm upset that said licensing is based more around establishment dogma (standard of care via USDA) than actual known nutritional science.
