MIGRAINE HEADACHES » food triggers & remedies + free tracking PDF

Migraines can become an enormous source of anxiety for those who suffer from them. For some people they can be debilitating, forcing us to miss projects, tests, work, and important events.

So what causes migraines and what can we do about them? We'll explore that in this article.

What is a migraine?

Classic symptoms: a headache occurring on one side of the head which can lead to nausea, vomiting, vision or hearing disturbances, and/or sensitivity to light and sound.

Migraines generally start off gradually. It's typically dull, deep, and steady pain, however, it can become throbbing and pulsating as it intensifies.

Migraines affect three times more women than men, and episodes can start as early as 12 years old.

Auras: some migraine sufferers (20%) experience symptoms prior to the onset of a migraine, such as flashing lights, bright spots, zig zag lines, numbness or tingling in their hands, lips, tongue, or face.

Interestingly, migraines do not always cause a headache, there's a small percentage of people who have visual migraines; these people can lose a portion of their vision during their migraine, but they don't experience a headache.

What causes migraines?

1. Family history: 90% of migraine sufferers have a family member who also gets migraines.

2. Lifestyle triggers: dehydration, lack of sleep, hunger, stress, strenuous exercise, or an iron deficiency can all contribute to migraine headaches.

3. Hormonal imbalances: including menstruation. Unfortunately, our "time of month" can cause hormonal imbalances - whether just before, during, or after our periods - that can lead to the onset of migraines.

4. Food triggers: diet can play a surprisingly big role in preventing and managing migraines.

How can diet affect migraines?

There are several dietary components that can contribute to headaches. This includes:

  • Hunger - migraine sufferers often note that skipping meals can cause headaches. To avoid this, try eating every 3-4 hours.

  • Nutrient deficiencies - such as iron, vitamin B2, and magnesium (more on this below).

  • Caffeine - more on this below!

  • Food triggers - let's explore this further...

Some foods can cause a change in chemicals in the brain which cause thereby headaches, or they cause inflammation which can lead to a headache. Here are some examples of potential triggers:

  • Tyramine - found naturally in foods such as:

  • aged cheeses (blue cheese, feta, cheddar, gorgonzola, parmesan, Swiss)

  • cured/processed meats

  • pickles

  • canned soups

  • certain beans (fava, broad, garbanzo, lima, pinto)

  • some overripe fruits (bananas, tomatoes, avocados)

  • Food additives - like nitrates, food colouring agents, artificial sweeteners, or MSG, found in things such as:

  • soy sauce

  • lots of packaged foods

  • Tannins, phenols, and sulphites - which can be found in things like:

  • black tea

  • bananas

  • apple peels

  • red wine

  • dark chocolate

  • Caffeine - withdrawal from caffeine can also be a major cause of migraines and can be found in things like:

  • coffee

  • tea

  • energy drinks

  • colas

  • Food sensitivities or nutrient deficiencies - can also be a culprit.

» Note, these are possible triggers, but since everyone is unique what might cause a migraine in one person might not have any affect on another. If food may be the culprit in causing migraines, try our tracking using our headache journal (see below) or see a registered dietitian for additional support.

If you think something might be the culprit, we advise changing only one thing at a time to see if it has an affect on your headaches. Too many changes at once will make it harder to determine what may or may not have been contributing. On that note, we also suggest slowly adding back foods that have been eliminated, to see if they can be tolerated again. Trigger foods can be "dose" dependant - for example, a whole dark chocolate bar might cause a migraine, but 1/4 of it might not.

» A note on elimination diets: we strongly recommend elimination diets only be done under the supervision of a dietitian, as it can become complicated, confusing, and frustrating, so it's important to have a trained health provider by your side.

Caffeine: friend or foe to the migraine?

If you've ever experienced a migraine before, you might have noticed that drinking some coffee can help. In fact, caffeine is an ingredient commonly found in over-the-counter headache medications, but, for some people, coffee can be the culprit causing the headaches.

Caffeine's affect on the brain depends on how often we use it. If you drink coffee seldomly, having one cup might relieve your headache. However, if you're a regular coffee drinker, there is likely very little it can do in alleviating the headache given the body has developed a tolerance to it. For those with chronic migraines, it's recommended that coffee be avoided altogether.

Also note that caffeine is a drug, and as with any drug, overuse can cause problems. Drinking coffee daily can cause "rebound" headaches, and quitting caffeine "cold turkey" can also cause migraines. If you feel you'd like to decrease your caffeine intake, we recommend decreasing it gradually. And remember, caffeine is in more things than just coffee!
