This site hosts my own low-histamine recipes, as well tips for converting other recipes to LH, and links to other people's recipes that happen to be LH.
I (Sukie, who made this site! Hi!) have been eating a low-histamine diet for the past 8 months or so (as of April 2022), after having realised that I have MCAD/S (Mast Cell Activation Disorder/Syndrome).
MCAD/S is one of a few illnesses that make eating food that contains histamine, other similar -amines, or histamine liberators, very difficult. Eating these things tends to manifest as what looks like an "allergic reaction", which can be something as extreme as anaphalxis or as mild as a headache. Either way, it's generally best to avoid ingesting them if they're making you ill.
Sounds easy enough, right? Just avoid the foods that make you sick! Not quite. The trouble is, A LOT of foods have histamine, similar -amines, or histamine liberators in them. It's also not as simple as looking up a list of "good" or "bad" foods, since what can trigger horrible symptoms in one person, can be completely fine for another. Figuring out what foods you can safely eat takes a long time, a lot of trial and error, and often leaves you with a distressingly small list of "safe" foods. This is further complicated by the fact that histamine builds up over time in all foods, so food needs to be eaten as freshly as possible - what was once a safe food can give you a horrible reaction after a couple of nights in the fridge.
Unfortunatley, if you're struggling with eating histamine, the best way to figure out what you can eat safely is simple trial and error. Anyone claiming to have a comlpetely comprehensive list of foods you'll definitely be able to eat is probably trying to sell you something. A period of an "elimanation diet" will hopefully give you an idea of which foods you can eat without problems, but make sure you talk to your doctor about it first! It can be helpful to talk to other people eating LH to see what they can tolerate, as well as researching what foods are always recognised as high histamine or histamine liberating (like tomatoes and citrus fruits!) - but there will probably be lots of differences between your "safe" list and anyone else's.
The recipes I post here are all made using ingredients that I myself can eat without having a reaction. There will be places our tolerated foods overlap, and there will probably be things I can eat that you won't be able to, or things that I can't eat that you can! For this reason, each of my recipes comes with suggestions for what you can substitute the ingredients with, and they're mostly built around what purpose any given indregient would serve. For example, coconut oil is a fat, so when subsituting it, you would just need to use another kind of fat that you can tolerate.
No, it is not a fad diet. This is a diet that should only be used by people for whom it is a medical necessity. While there are absolutely no benefits to eating LH if it isn't medically necessary for you, all of the recipes on this site are delicious anyway, so feel free to try them even if you don't need to. Incidentally, a lot of them happen to overlap with other medical diets - for example, as part of my MCAS, I can't tolerate gluten. As a result, a lot of these recipes will suit other dietary styles, and are designed to be versatile for your choice of ingredients. One diet I would not recommend mixing with LH, from personal experience, is veganism. Quite simply, when you have a tiny amount of safe foods to choose from, I cannot recommend artificially restricting that group even more. I was vegan for a long time until I got sick, and I had to start eating animal products again, because without them I just wasn't getting enough protein and iron in my diet. Trying to stay vegan on an LH diet is, in my opinion, a road to malnourishment.
Hell no! Take anything I say here with a pinch of salt, do your own research elsewhere, and consult a doctor before you make any changes to your diet. I'm just someone with an illness, sharing how I manage my own symptoms.
