Mario, I agree with you - wheat is not required in the diet - and I have almost eliminated it completely from mine. I don't eat much wheat - mosty because it's hard to find wheat products that don't also have some form of sugar and lots of preservatives.
There are some important nutrients in wheat and of course lots of fiber in whole wheat, but if you get those things elsewhere, there is no need to eat wheat.
My wheat intake consists whatever wheat is in the Amy's food products that I eat daily

, and occassionally a slice of whole grain bread or some triscuit crackers.
