Eat all the beans you want- just not processed wheat flour.
If you don’t want to try it then don’t.
All I know is it changed my whole life. I feel better than I did 20 years ago.
The only “wheat flour” I eat is from organic, sprouted whole wheat kernels. It makes a huge difference.
The effects you were alluding to I experienced from all white flour...which is just sugar with gluten.
