Reddit reviews Dealing with Food Allergies: A Practical Guide to Detecting Culprit Foods and Eating a Healthy, Enjoyable Diet

I did mine based on my symptoms and a blood based allergy test. I also used this book, which there's a newer version for that I'm not sure about. Also, be careful about food additives, some brands can have additives that are potential irritants and such.

Just alcohol can do it - I thought it was hops at first for me - but it's the alcohol. Does older meat affect you more than fresher meat? Like meat eaten at a restaurant or leftovers from last night. Chocolate is high in histamine. Tea is also tricky. I've figured out the kinds I can get away with. Dairy like yogurt, sour cream, cheese, or just plain milk? I think egg whites are supposed to be high in histamine. I seem to be ok with eggs but I don't eat them daily either. Can't eat strawberries but I can eat blueberries (now). I don't eat meat (cooked at home) that's more than about 48 hours old. When making food to be put in the freezer for later (like a big batch of soup) it's always frozen before the 48 hour mark. Tomato, vinegar, and fish are the biggest things that are ingredients in lots of things that I avoid. (I'm working on adding fish back into my diet from specific sources only.)

I take antihistamines, quercetin (started recently), and watch my diet. It's tricky, frustrating, and sometimes really hard. Other times it's not much of an issue. Stress throws everything off. I'm actually on a lot of meds for other issues too. I can't really eat out anymore. I miss a lot of things because people like to do FOOD + activity.

This book has been life changing. That sounds dumb or melodramatic or like I'm selling something, but it's just true.
