Yeah the chickpeas etc are not in the diet. I only eat them like once every two weeks. And its not like they are harmful or anything, they are simply not "optimal" nutritious foods, because of low etheric energy and unbalanced aminos etc
The potatoes, on the other hand, are inflammatory and defintely not good. Plus I think these kinds of mainstream foods have a much higher rate of genetic manipulation etc.
He does state in various articles that yams, sweet potatoes etc are okay if taken two times per week. Just Google "sweet potatoes drwilson"
