I'm 32 and have been off wheat, barley, rye, and oats for the last 17 or so years.
At 15 if I didn't stop, Death was not long ahead. I was dieing of starvation, as everything I ate went right though me. I was also bleeding to death from the inside out. I would sleep 20 hours a day, and almost didn't have enough strength to go to the bathroom. I learned all I could about nutrition, and turned my life around.
Now at 32 I'm stronger, more healthy, and feel better than anyone else I know my age.
I also don't eat refined sugar beet sugar. If I do I'm back on insulin the next day. As a plus to this I don't get sick, at all. It's been years since I have even had a cold.
Just last year I came across this video. It made perfect sense of everything. I wish I had found it years sooner.
Without our health, we have nothing.
