Check out the book Heal Your Headache or check out The Dizzy Cook - she has a summary of the book and all migraine food triggers. Link is below. Interestingly - dairy, sugar, gluten are not typical triggers. Nuts are, however. My guess is the almond milk was the trigger in the ice cream. The biggest issue is called tyramine and it builds up in foods over time so the biggest things to avoid are anything aged, fermented, pickled, preserved (including all alcohol, except maybe vodka, and any vinegar except distilled white vinegar). Also, any meat that's been cooked for more than 1-2 days. Histamine can also trigger migraines and is in food. It's very hard to say which specific foods trigger migraines because it could be something different each time. Chocolate might trigger a migraine on one day, and not on another day, depending on what else you've eaten or done.It's a very hard diet to adapt to, but once you get the hang of it, it's not too bad, and it's 100% worth it. I recommend doing a complete elimination for two weeks and then adding foods back in to test them. I try to follow it 100% at home (except for a few foods I've added back) and then when I'm out of the house I just do my best. Things I completely avoid, because I'm 90-100% confident they are triggers:SoyMSG (which is in a lot of things. MSG is technically a spice so I don't eat anything that just says "spices" on the ingredient label)All liquor except vodkaLeftover meat more than two days old Aged cheese (though I'm starting to test it in small quantities) Citric acidMaltodextrin, yeast extract, autolyzed yeast - according to the book these are basically MSGBeans other than black beansChocolate - I'll eat no more than one biteMushroomsCured meatCoffee - this is a weird one because sometimes it helps. But I'm now off it completely because of sleepAll bars with chocolate, nuts, or fake protein - I eat 88 Acres bars which are pretty much the only ones that are compliant Things I'll eat when I have to or in small quantities:YogurtOnions LentilsNutsParmesan Mixers in vodka, like other liqueurs, and other clear liquors like gin or tequilaThings I've added back completely:CitrusAvocadoMalted barley flour (though I still avoid it at home) All the histamine foods that aren't tyramine foods - salmon, spinach, strawberries, eggsTomatoeshttps://thedizzycook.com/category/hyh/
