I decided to stop eating gluten. If you have difficulty remembering which grains to avoid on a gluten free diet use the acronym BROWS.
B = Barley
R = Rye
O = Oats
W = Wheat
S = Spelt
Guess what? Right! My joints started feeling even better and the stiffness decreased.
I did read that most people should not eat a 100% gluten free diet forever. So every now and then, after a few months, I eat a little organic whole mixed grain bread that I purchase from Costco.
