Went gluten free in 2003 because of severe peripheral neuropathy. Giving up gluten made a fantastic change in my health. Not only did my PN symptoms improve but my fatigue, brain fog, shortness of breath, pitting edema in my legs(in 2000 I had cardiac bypass) and many more symptoms disappeared. The changes were miraculous. Very quickly I realized that I felt my best when I did not eat any grains and sugars but they were not totally out of my life. About 2008 I bought a glucometer and found that I could easily spike my blood sugar over 200. That is when I got serious about the low carb paleo diet. I am loving life and feeling good and enjoying retirement.
