Preservative-free and salicylate-free diet: Any tips?

I just checked a medical advice forum and finally got an answer regarding what exactly is going on with my 😁😁😁. For the longest time, I was under the impression that I was simply allergic to "SOMETHING" 😵😵, when in reality, I am dealing with chronic urticaria.🙂 It manifests quite specifically: every morning, the mirror greets me with dark circles under my eyes that look like massive pillows, my lips look like I stepped straight out of Harlem, and I have these "slits" on both sides of my neck that are wide enough to let me float comfortably down the Mississippi all the way to the Black Sea. And the worst part is, this happens year-round—autumn, winter, spring, summer, and then it all starts over again.
So, my kind Doctor explained that I need to switch to a diet free of preservatives and salicylates. I am reaching out to all you wonderful people to ask: if you deal with this or anything similar, please reach out with some menu suggestions for this type of diet.
KISSES AND HUGS!!!!!!!!!!

Forget that canned stuff—it’s all farm-fresh from the local market, even the tomato sauce. Basically, we're talking premium organic baby food 🙂
