I've heard that they had no nutritionists onboard...
So if the people involved in this project consider themselves qualified in the field of nutrition, I don't see how that makes them different to anyone else speaking or giving advice on the subject.
A big organization with lots of money doesn't automatically make a group of people a legitimate authority on anything. After all, you can get all sorts of qualifications in things that are clearly quackery, e.g. homeopathy.
Please stop it with the Dwight references. I beg of you.
Your karma wallet does the same.
