Always the RDs, not MDs, that squawk over this stepping on their turf.
Caryn Zinn, an RD, was in hot water with the NZ RD association over her public stance on high-fat, though not charged with anything and continues to practice.

But this RD has good points...how did this come about that one Ministry hired someone whose Advice conflicts with the Health ministry? The material currently distributed by a child's doctor and in the school's health classes will be at odds on major parts of exactly what is healthy food. In the US, low fat milk is mandated in schools and the food programs, how will this work in NZ? Prof Schofield has quite the job ahead.

Many thanks Grav for the TV video and these quotes
