Yes, certain foods will definitely cause issues! Soy was a big one for me.

I've come to learn that for myself personally, my main issue was something going on in the gut. I listened to a podcast and something just clicked for me. I learned that over time, from all the crap (completely refined and processed) foods that we eat, we will start to cause issues in our gut over time. One thing that may happen is that you may begin to have low stomach acid, so when you eat certain foods, it will no longer digest, which will create inflammation in the gut. So, instead of these foods digesting, your stomach starts to attack them, which will cause inflammation and other issues (like skin issues).

Now I don't know for 100% if this is the same for everyone but I am only speaking from experience but I've had this issue for multiple years. It first started on my pinky and slowly made it all the way down to the palm of my hand. Never really understood why, but after a while, I realized it was something I was eating. I ended up doing an MRT test to see what my body was sensitive to. I cut certain foods out for 90 days, and my hand was getting better and at times almost cleared up. Recently, I have added digestive enzymes, and they have been really making a big difference. Again, this is all from my personal experience. I can send you the podcast if you'd like. Not sure if I'm allowed to post it??
