Migraine Food Triggers

The relationship between food and migraine is one of the most talked-about, and often most confusing, aspects of managing this condition. You may have heard that chocolate, cheese, or red wine can cause a migraine, and perhaps you’ve tried cutting out certain foods with mixed results. It can feel like a frustrating and restrictive guessing game. If you’re trying to make sense of it all, please know that you are not alone in this challenge. The truth is, while food can be a trigger for some people, it’s a highly individual and complex issue. This guide is here to offer a compassionate, balanced perspective on food triggers and to provide a gentle framework for identifying what might be relevant for you.

How Can Food Trigger a Migraine?

A "trigger" is any factor that can increase the likelihood of a migraine attack starting. It’s helpful to think of the "threshold" theory. Imagine you have a migraine threshold, like a bucket. Every trigger—poor sleep, stress, hormonal changes, a weather front—adds a little bit to that bucket. When the bucket overflows, a migraine attack begins. For some people, certain foods or ingredients can be one of the things that adds to the bucket.

Certain chemicals in foods are thought to be the culprits. These substances can affect blood vessels or interact with the sensitive nervous systems of people with migraine. It’s important to remember that this is not an allergy or an intolerance; it’s a specific sensitivity related to the migraine disease process.

Commonly Reported Food Triggers

While triggers are highly personal, there are some foods and ingredients that have been more commonly reported by people with migraine.

Aged Cheeses: Foods like blue cheese, cheddar, feta, and Parmesan contain a substance called tyramine, which can affect blood vessels.
Processed Meats: Cured or processed meats like hot dogs, bacon, and deli meats often contain nitrates and nitrites as preservatives, which can be a trigger for some.
Alcohol: Red wine, in particular, is a frequently cited trigger. This may be due to substances like tyramine and sulfites, as well as the dehydrating effect of alcohol itself.
Chocolate: This is a controversial one! For a long time, chocolate was blamed as a major trigger. However, recent research suggests that a craving for chocolate may actually be part of the prodrome phase (the pre-headache stage) of a migraine. So, you might crave chocolate because the migraine is already starting, not the other way around.
Food Additives: Monosodium glutamate, which is often called MSG, a flavor enhancer found in many processed foods and restaurant meals, is a well-known trigger for some individuals. Artificial sweeteners, especially aspartame, can also be a culprit.
Caffeine: As we’ve discussed in a separate article, the relationship with caffeine is complex. Too much caffeine, or caffeine withdrawal, can both be triggers.

A Patient's Story: Maria's Detective Work

"I was convinced that everything I ate was causing my migraine," says Maria, 44. "I cut out so many foods that my diet became incredibly restrictive and stressful. It was only when I started working with a headache specialist that I learned a more gentle approach. She had me keep a very detailed diary of not just what I ate, but also my sleep, my stress levels, and where I was in my menstrual cycle. After a few months, a pattern emerged. It turned out that my main trigger wasn't a specific food, but rather skipping meals. On a stressful day when I forgot to eat lunch, I was almost guaranteed to get a migraine. It was so empowering to realize it wasn't about 'good' or 'bad' foods, but about consistency."

A Gentle Approach to Identifying Your Triggers

The key to understanding your relationship with food is to be a gentle detective, not a harsh judge.

1. Keep a Detailed Diary

This is the most important tool. For at least a month, track everything: what you eat and drink, when you sleep and wake up, your stress levels, the weather, and your menstrual cycle. When a migraine occurs, note the time it started. This will help you see the bigger picture and identify patterns, not just single events.

2. Look for Consistent Patterns

A true food trigger will usually cause a migraine within a few hours of being eaten, and it will do so consistently. If you eat a food one day and are fine, but the next time you eat it you get a migraine, it may not be the food itself. It might be that the second time, your "trigger bucket" was already fuller due to other factors like poor sleep or stress.

3. Consider an Elimination Diet (With Guidance)

If you and your doctor suspect that certain foods are a problem, you might consider a formal elimination diet. This involves removing all commonly reported trigger foods for a period of time (usually 4-6 weeks). Then, you reintroduce them one at a time, every few days, to see if a particular food consistently triggers an attack. It is so important to do this with the guidance of a doctor or a registered dietitian to ensure you are still getting proper nutrition.

Focus on What to Add, Not Just What to Remove

It can be much more empowering to focus on a healthy, consistent eating pattern rather than on restriction.

Eat Regularly: Skipping meals can cause your blood sugar to drop, which is a very common trigger. Aim for three meals and a couple of small snacks throughout the day.
Stay Hydrated: Dehydration is another major trigger. Keep a water bottle with you at all times.
Focus on Whole Foods: A diet rich in fresh fruits, vegetables, lean proteins, and whole grains can help to keep your body and brain stable and healthy.

A Final, Compassionate Thought

Please be kind to yourself on this journey. Food is meant to be a source of nourishment and pleasure, and it’s easy for it to become a source of anxiety when you live with migraine. Remember that for many people, food is only a minor piece of their migraine puzzle. Working with a healthcare provider can help you put food in its proper perspective and develop a holistic management plan that works for you.
