Reddit reviews The AntiHistamine Diet: Lower Histamine, Increase DAO, and Reverse Histamine Intolerance in Six Weeks

There's a TL;DR at the bottom for convenience lol.

It sounds more complicated than it really is. Basically I looked up low histamine diets on the various MCAD/POTS groups I was in on Facebook, and they had a few documents about some things there to start with. It was either Christmas or my birthday (I forget which one) and my parents got me these books (book one, book two). There's another book or two around here somewhere but I can't find it at the moment to get the info.

They got me the printed form, but these books seemed like they were printed as an afterthought, and were meant to be an ebook instead (price confirms theory). Low histamine is a pain to stick with, especially if some of the staple items that they suggest to eat cause issues for you (like me), but me and my girlfriend went through the various plans and basically picked out meals from each of those books and a couple other meal plans we found online. She was previously a strict vegan for a handful of years so she has recipes for that we incorporate into our meal plan with twists on the ingredients as needed.

We make sure to try and purchase as healthy as possible ingredients, least processed stuff, less dyes, less artificial sugars, etc. I stay away from dairy with exception of eggs. They have to be either hard boiled or fully cooked scrambled - ie pretty much the dry chalky charred point or they'll give me a histamine fit that will turn into a IBS-D fit with me running straight to the bathroom. Essentially we just kind of tried different things to see what we all liked, and what was easiest/cheapest to make out of the plans, and then kinda went from there.

TL;DR: What I'd recommend is to educate yourself on the major histamine trigger foods and eliminate them or at least educate yourself on histamine foods in general. This book goes over a lot of the bigger ones if you want a quick read to get up to speed. Then create a food journal because with MCAD we are all so vastly different it's hard to really give detailed diet plans to one another. We all have to kind of start somewhere and see what works for our own selves.
