This is another example of group-think in scientific research. The same thing happened for decades where low fat diets were supposed to help for heart disease but that has only recently been reversed after decades of indoctrination. This happens all throughout scientific research, where science is supposed to be immune to this, but it's obviously not. So many things we take as gospel, only to be reversed decades later, and it has to do with how things get funded which is unfortunately leading society the wrong way.
