To make a long story short, nightshade foods were the cause of my cholinergic urticaria! I went through a massive and time-intensive food elimination protocol, spanning over many weeks, and came to the irrefutable conclusion that nightshade foods were the cause of my heat hives.
What I find most interesting is that one article states that nightshade foods “inhibit the breakdown of acetylcholine.” Wasn’t it described here on this forum/YouTube channel that acetylcholine is involved in cholinergic urticaria?
Once I read this article, I cut out nightshades, and I was 100% cured–not 95%, not 98%, but 100% cured. I don’t get the thousands of red bumps when body temp rises, and I don’t even get the itchy prickly skin, either!
Common nightshade foods:
- bell peppers
- white potatoes (NOT sweet potatoes)
- peppers (think hot sauce)
You know what the sad thing was? I was eating bell peppers every morning with breakfast (+pepper hot sauce! in my breakfast burritos). I was eating white potatoes everyday with lunch, and I was eating tomatoes almost every night with dinner!
So, I was essentially eating the heat-hive causing food with almost every single meal. No wonder my hives got out of control recently.
I wish you guys the best and hope this might help someone out there.
