You hear a lot about migraine food triggers but how do you know if you actually have them? The most accurate way to find out is through a migraine elimination diet.
The Heal Your Headache diet, also the Johns Hopkins Migraine Diet, is meant to be an elimination diet, which means you’re strict about it for a period of time with the intent to re-introduce foods when you feel better. The reason for this is not only to discover if you have any migraine food triggers, but also to lower your migraine threshold.
Unfortunately if you're not feeling better or having breaks in your attacks, it can be nearly impossible to tell if you have food triggers. In this post I break down when to reintroduce foods and what the best way to go about it is for a migraine elimination diet.
How to Raise Your Migraine Threshold
A migraine threshold is the breaking point of how many things you can tolerate before triggering a migraine attack. Increasing your migraine threshold can be done in a number of ways. For many people exercise, medication, supplements, hydration, sleep schedule, therapy, diet, and whatever seems to help you best all combine into your treatment plan to help you raise that threshold.
These pieces stack on each other to raise your overall threshold, making it much harder to trigger a migraine attack. For this reason, we want to add in a lot of things that can potentially raise our threshold so we can live a somewhat normal life and not always be worried about what food we ate or how much sleep we get.
Another reason to increase your migraine threshold is to allow your brain some time to calm down. If you feel like you're having attacks all the time, your brain is overly sensitive and every little thing seems to set you off. Taking potential food triggers out of the mix can aide with this process over the course of a few months.
So even if you don’t discover a bunch of massive food triggers, you can still be helping yourself improve by following the diet.
Why Be Strict on a Migraine Diet?
If you’re not strict and eliminating everything on the plan, you may be allowing that threshold to lower, even just a bit. This opens yourself up to being triggered more easily by bright lights, loud noises, movement, etc. This is like taking a preventative medication 4 out of 7 days and still expecting it to work the same - it just doesn't.
Also if you’re eating something every so often that’s actually a trigger for you, it can be extremely difficult to pinpoint if you’re also having symptoms daily. Some people have a spike in symptoms that are even worse than what they experience daily, others just can’t tell.
Being strict on the diet for a limited amount of time takes out any guesswork. You don’t have to wonder if it’s the chocolate you had last night or the bacon you had this morning, it becomes very clear what a trigger is once your brain has had a chance to calm down.
Having a set plan and testing foods in a controlled setting will make it more obvious what your food triggers are, so you don't end up placing the blame incorrectly.
So often this can happen where people get symptoms after a meal and they blame the food, but really it could've been the stress from that week combined with low hydration and a change in weather. Perhaps the piece of chocolate that set you off that day would normally be fine if you didn't have those other things going on.
Why I Tried a Migraine Elimination Diet
When I began the Heal Your Headache diet, I was still having 24/7 dizziness, lightheaded symptoms. I had been on medication and supplements for about 4 months and was feeling a bit better without severe vertigo, intense disequilibrium, or dissociative vestibular migraine symptoms.
Occasionally I would have the walking on marshmallows feeling and pretty bad light and sound sensitivity. A lot of people claim a migraine diet is restrictive, but I actually felt more limited having chronic migraine and trying to go to a restaurant than I did feeling better on a migraine diet, but having fewer options when eating out.
I cooked more at home for months so I COULD actually go out and enjoy a restaurant without wearing sunglasses and wanting everyone in the room to shut up. A part of me figured, it has to get better than this...and it did!
What to Expect
Heal Your Headache recommends reintroducing foods when you reach a migraine "baseline" - which means a reduction in severity and frequency of attacks. This can be different for everyone. For me, personally, I waited till I was having a good amount of totally dizzy free days to reintroduce foods, which was closer to 6-8 months.
About 2 months in I wasn’t noticing a huge change in my symptoms. I still had daily dizziness and I was very frustrated I was putting in all this work for zero changes. That night I tried tzatziki with my lamb dish, which contains yogurt. Yogurt was an item I used to eat daily for breakfast and I never noticed that it spiked my symptoms at all. Within 30 minutes, the table felt like it was moving on me and I experienced a really severe attack, similar to what I used to go through before taking medication and supplements. I decided there must be something to this and I should stick with it a little bit longer.
About 4 months in I was feeling better and started having actual breaks in my dizziness, but was still experiencing symptoms daily. So I decided to stick with it a little bit longer.
Finally around 7-8 months I felt comfortable reintroducing foods. I was having actually dizzy free days, or the dizziness would be so light it really wouldn’t bother me. I could exercise, travel, and drive again without being nervous at all. This was my “baseline”.
Not everyone takes as long as I did to see results. I've had messages from some readers with relief within 4 weeks, others have taken almost a year! I will say generally, you should be seeing some kind of results after 4 months to tell if this is actually going to work for you.
Even if they're slight results, like maybe you still have daily symptoms but you're no longer having vertigo attacks, that's still an improvement and a reason to keep going.
How to Find Migraine Food Triggers
The best way to find out if you have migraine food triggers is to test them in a controlled setting. It shouldn’t be over your period, during final exams, in the middle of a European vacation, when your in-laws are visiting, during crazy weather changes, etc.
Test one food for 3-5 days. Some doctors have said food triggers can trigger an attack up 2 days later, but I think that’s a little extreme. Most of mine, and for many of my readers, were noticeable within 30 minutes to a day at the most. They were also pretty obvious. I’d have a clear spike in symptoms. And this is why it can be easier to recognize food triggers when you’re having symptom-free days.
If you start to get really bad symptoms and don’t think you can continue for the whole time, I like to write that food down and keep it in my memory. Continue to eliminate it and try to reintroduce later.
Are Food Triggers Forever?
Once you discover if you have migraine food triggers and what they are, it may feel overwhelming. Perhaps one of your favorites seems to trigger symptoms for you. Don't worry! This is where raising your migraine threshold can be super important.
For a while when I was reintroducing foods after the elimination, I felt like a lot of things raised my dizziness. One in particular was avocado, and I love guacamole. This was one of those foods I decided I would have as a treat every so often, when I had a higher threshold day.
Over time, I noticed my sensitivity to avocado had diminished and now it's non-existent. I can have guacamole on occasion and not have any symptoms at all. Why is this? Well, my migraine threshold is a lot higher now than it was back then!
My point is, don't just write off foods forever. As you feel better, keep giving them a try. I still struggle a lot with yogurt and certain nuts unfortunately, even years later, but for the most part I can freely enjoy most foods without worry. I do try to keep in mind when my threshold is a little lower, with stress, lack of sleep, and weather changes. While I can't get away with wine and guacamole and MSG, maybe I could do guacamole and half a glass of wine with a wine wand if I'm careful about what my food is seasoned with.
Tips for Reintroducing Foods after Elimination
If you feel ready to reintroduce foods after an elimination to discover if you have migraine food triggers, here are a few tips.
- Start with the foods you miss the most. This could be foods just love or it could be the foods that cause a total pain for you to not eat – like onions or citrus. I started with onions, citrus, and avocado. I love avocado, but being able to eat citrus and onions really opened some doors for ordering out. Especially with salads.
- You don’t have to reintroduce everything. There are some foods I don’t love and never reintroduced. For instance, I never did an official re-introducing of peanuts because I found I loved sunflower seed butter so much more. I’ll eat it here and there at restaurants and it doesn’t seem to bother me, but I overall I just don't really care to bring them back in. And things like MSG and additives, my life is just better without. I personally love reading labels now and choosing the best options for my health.
- Migraine food triggers aren’t always triggers forever. Just because something triggers you now, doesn’t mean it will a year down the road. As you begin to feel better, it’s sometimes easier to tolerate more. This was definitely the case for me! Things like avocados and cashews used to bother me, but now I tolerate them fine.
- Be patient. This process does take time. I know when you’re feeling better all you want to do is eat all the foods, but going off the deep end may end up in a few unexpected attacks or decrease that threshold real fast.
- Don’t let others influence you. My food triggers are yogurt, most nuts, and caffeine. It doesn’t really make sense and I can’t draw a conclusion as to what I’m reacting to as far as tyramine or histamine, but at the end of the day, it doesn’t matter. Those just make me feel like garbage. I’m automatically dizzy and out for the rest of the day. I’ve had so many people over the years try to tell me a migraine diet is stupid and that nuts are good for me, or I need the probiotics in yogurt. Why would I eat them if they make me feel like garbage? Because someone on the internet says they're good for me? You know your body best. Don’t let anyone else tell you what it needs. I can get great nutrition from other sources!
The Willy Nilly Approach
I’m going to be honest, I wasn’t perfect on my reintroduction of every little thing. I was one of the impatient people I tell you not to be above. Now I didn’t go crazy for days, but I did go out to eat and enjoy myself a little bit more. I was feeling good! And reintroduction the "good old boy" way takes a really long time.
I always tried to stay away from my big, known triggers, but I didn’t question the servers about every little ingredient in what I might be ordering. There were times it lashed back on me and I couldn’t pinpoint a source. It’s easy to blame food, but it could have been the candle flickering or the loud noises combined with potential migraine food triggers.
Sometimes I could draw a connection. Like on a vacation in France when we had a dish full of walnuts and I felt so dizzy the rest of the day. It raised a red flag, enough that I formally tested it again at home to find walnuts were (and still are) a really bad food trigger for me. I do believe you can kind of gauge triggers this way if you’re really in-tune with your body. It’s certainly not the recommended approach, but we’re all human. However, you do need to test things more than once to make sure you're not unfairly blaming a certain food.
This is also how I discovered almonds were a trigger of mine. My local grocery store was out of oat milk and I thought I would give Malk almond milk a try. Almost instant dizziness, just like caffeine. The same thing would happen if I went out and had a dish with a lot of almonds in it. It got to the point where I realized every time I ate almonds, I would get an increase in symptoms.

Love this page and your facebook group. I have been on the HYH diet for close to a year now. (I was on it a few years back and it worked wonders for me - my MAV came back so I got back on). I am doing so great now and going to start reintroducing foods. Chocolate is my first choice haha!
I was able to reintroduce it so I hope you have good luck as well! 🙂
Hi, Alicia and thanks for this post! I just re-introduced organic decaf (Swiss water process) after 6 months on the elimination diet. After a couple days, I had a super foggy feeling head. I’m thinking it was a coincidence, but can you suggest how I can figure out if it’s a trigger? Thanks!
Hey Sharon, the best thing to do is to give yourself a few days off and then try again and see if the same thing happens. Note what else happened that day - if you got less sleep, weren't as hydrated, maybe stress?
Today I've completed 8 weeks on the HYH diet! Reading this post and the one on Migraine strong was so helpful today! I have definitely seen an improvement in symptoms, but have chronic VM and still have daily symptoms. It's very helpful to know what kind of time frame worked for others in similar situations. Thanks so much for sharing your story and all your hard work to help others!
You're welcome! I recommend to keep going with it if you have seen an improvement but still have daily symptoms. It will probably get even better!
