First of all, I'm SO glad to hear that you were finally sent for patch testing! It's seriously life changing for those who test positive. I really, really wish it was included in the "preventative care" category in our annual physicals. I'm so sorry to hear about your rheumatoid arthritis diagnosis. I'm glad you brought it up, though. I did a little research and it looks like rheumatoid arthritis does indeed under the autoimmune umbrella along with allergies and eczema. The body is essentially attacking itself. (I read about that here). From what I've seen, people with autoimmune issues often have more than one... it's just a matter of which combination your body decides to have. I wish there was a safe, instant and permanent solution to getting our immunity and health back to 100%!
Honestly, the best logic to follow in eliminating propylene glycol is to go 100% organic. This can obviously present the unfortunate issue of high prices and inconvenience. A more realistic option is to cook most of your food from scratch and try to stay away from highly processed foods. When I do choose something processed, I make sure to read the label and learn about hidden ingredients. When it comes to eating out, I have a good handful of local places that don't seem to bother me. I stick to those. While I can't have fun by switching it up and try new restaurants all the time, I can have fun trying new recipes at home :-) I usually stick to cooking with whole foods and other basic ingredients like oils and herbs.
If you buy produce that isn't organic, make sure to wash/scrub it well. There are certain things like cucumbers that I started always buying organic because regular store-bought cucumbers have this gross, waxy layer applied to them. It's difficult to scrub off, unnecessary and rather unappetizing.
