Hubby has to go grain free!

We went to the Dr today for a follow up on my hubby's blood pressure, well we found out a specialist didn't tell us the truth last year after hubby had an ECG they told us it was normal, well it turns out it wasn't his heart is enlarged with slight function issues, but not enough to warrant meds yet.  Then we found out my hubby is most likely sensitive/allergic to grains (Celiac Disease kind of) so we were told that we had to cut out all grains out of the diet including rice, we are both Carbohydrate addicts, but since I have PCOS it is probably for the best that we cut out grains, sugars etc.  So it will definitely be an adventure...but since we are already stocking up on meats etc for the dogs, hopefully it won't be too difficult....although definitely going to have to do more research on it.
