I was trying to be flippant, which is fun for me but obviously not very helpful, so let me rephrase my answer.

I agree there is a non-zero amount of grains that is healthy to consume, but your answer doesn't say anything about what that amount should be, and as such just states something that is pretty obvious. It would improve your answer a lot if you stated which quantities you are thinking of, and even more if you include sources.

From your original comment I honestly was not able to tell that your recommendation was to eat cereal daily in the amounts recommended by the back of the box.
