So it would seem, if we considered Nutrition Science alone. But that does not explain the process of increasing distrust in vaccination, global warming and climate change, or even evolution, where the scientific practice has a quite solid record and community consensus.

The erosion of authority reaches outside of Science, which to me suggests that there might be a broader explanation beyond the specificities of each field. In my opinion, and like you say, organized religion was one of the first victims of this process in the past and today.
