Erm…
Well, I appreciate the insights into possible foods causing an allergic reaction… But here’s my frustration. The cinnamon and multivitamin are from The Obesity Code’s chapters on how to fast. The Obesity Code is Dr. Jason Fung, who is referenced a lot here on the fasting stuff. https://www.audible.com/pd/Health-Fitness/The-Obesity-Code-Audiobook/B01MYMRVSQ
This is one of the most frustrating aspects of diet guides, the competing advice/evidence. It makes it difficult to keep up when there is conflicting information out there. The Obesity Code seems like a pretty reliable source and I sure wish there was a just one-and-only.
I’ve never had an allergic reaction to the Alive! multivitamin, which I’ve taken off-and-on for the past five years, and don’t think the natural ingredients could be extrapolated to real-life quantities. The cinnamon thing, I’m a little hesitant on that too, though if there is a food reason for my awful allergic reaction, I’d give that one the most credence. I did consume a whole lot of cinnamon.
