@iambenn They do not have any veterinary nutritionists on staff, but they utilize a third party consultant team for formulation. Their R&D team is full of highly educated individuals, but they don't do the formulating.
They really have 3 nutritionists at best, but they are intentionally vague on how many they have (leading me to believe they actually have 1 or 2 in actuality).
They also heavily rely on buzzwords and uneducated consumers to make sells. My biggest petpeeve being "human grade kitchens". Champion lists a bunch of regulatory standard procedures (meaning legally required) and acts like they are the only ones doing it, which is preying on consumers that don't know the regs.
Champion may have been unique in their approach prior to the passing of FSMA, but post-FSMA they are a run of the mill manufacturer with sub par scientific backing.
They also have one of the highest profit margins of any company I'm familiar with, but that's a personal issue I have, rather than once that effects others.
And yes I've read that paper, it is not a full research study on the topic. I know of multiple direct studies on this, and I believe the first is due to be published later this year or early next year.
