Regarding research. Taubes and others, their research and views threaten trillions in vested interests. Of course there is going to be pushback.
There is unfortunately a scientific industrial complex. Many researchers can't even get funding, might even have their careers destroyed if they don't support high carbs low fat and grains are good.
And Ancel Keys and T. Colin Campbell are some of the worst researchers around. I find their stuff awful at best. I wouldn't base anything I do on their work personally. Need to know who is funding work of people criticizing Taubes.
