No, it's really not. Once your system has been harmed to a certain point, it seems almost impossible to recover. You can only ingest so much poison, and each of us has a different tolerance level.
My wife can't touch wheat products anymore, literally. She'll break out in a rash wherever her skin comes into contact. She makes her breads from alternative grains and/or other sources.
I have backed off all wheat products substantially. Today I can eat something with so-called bread and not notice anything. But if I try to for more than a couple of days in a row, I'll start feeling it. My energy level drops, digestion is off (in a few ways) and I get a bloated feeling.
Best is if kids are brought up on the good stuff, so their bodies are strong. It's sooooo hard to get parents to listen though, since just giving them sliced bread, cereal and cheap snacks is so much more convenient. I wish I knew then what I know now, but I guess that's life, isn't it?
