They did not retract or change their position, though.
And they still publish information based on the same wording and conclusions they had when they did publish a position.
I'm not sure what's so confusing about this. They did not change their position on plant-based diets, and I believe because it would be redundant to keep saying what the science has confirmed year after year.
Is there any position they continually confirm year after year? If so, I'd be really surprised, unless the science isn't supporting their position, so they have to give their reasons for still having them.
The only article I linked was reviewed by their people just a few weeks ago, so it's as current as you could expect.
