I doubt that people back then knew that wheat, barley, etc. was harmful to the body. And, as Tomiro said, the gluten content of wheat back then was much lower. I'm sure that it still affected the body and mind and emotions, but, maybe, it was more gradual. I doubt people would put the two together
Today, some people don't feel the health issues gluten, and other similar things, cause until much later so it is hard to connect the two. It wasn't until recently that researcher did find the connection. And for those who do get bad effects from it, such as psychological and emotional issues, they just don't have the knowledge to link the two things together - gluten and whatever problem they are suffering from.
So the only way that anyone can question why Jesus didn't say that gluten was unhealthy and and should not be eaten is if that person thinks that Jesus was a omnipotent being. And, since Jesus was most likely Caesar, he was a human who had no clue that it would eventually harm a body, mind and emotions. fwiw
