As a former dietitian I say “yes” they are, just as doctors are in bed with Big Pharma. The trade organizations are policing units for the purpose of guarding acceptable dogma and treatment protocols for health professionals. If you venture too far past the standards you will be labeled as a quack and discredited even if the literature backs up what you say. This feeds the sick culture which treats symptoms but rarely considers the cause thereby creating repeat business. It is a business. A for profit business which should be known as Profitcare not Healthcare.
