A migraine trigger is any factor that on exposure or withdrawal leads to the development of an acute migraine headache. Triggers may be categorized as behavioral, environmental, infectious, dietary, chemical, or hormonal. The trigger theory supposes that exposure to various environmental factors precipitates, or triggers, individual migraine episodes. Many people report that one or more dietary, physical, hormonal, emotional, or environmental factors precipitate their migraines. The most-often reported triggers include stress, over-illumination or glare, alcohol, foods, too much or too little sleep, and weather. Sometimes the migraine occurs with no apparent “cause.”

Mine are brought on by the consumption of Nitrates. I started to first get migraines when I was about 6 or 7, and the doctors didn't know what was triggering them for a few years. Then they were able to narrow it down to Nitrates. They are most commonly found in processed foods like, bologna, and processed cheese, also hot dogs. But in the highest concentration in chocolate. That's what it is for me, so these are the things I have to avoid.

Migraine triggers
Migraine is irregularly episodic, so there needs to be some explanation for why a particular migraine episode occurs at a particular time and not at another time. A migraine trigger is any factor that on exposure or withdrawal leads to the development of an acute migraine headache. Triggers may be categorized as behavioral, environmental, infectious, dietary, chemical, or hormonal. The trigger theory supposes that exposure to various environmental factors precipitates, or triggers, individual migraine episodes. Many people report that one or more dietary, physical, hormonal, emotional, or environmental factors precipitate their migraines. The most-often reported triggers include stress, over-illumination or glare, alcohol, foods, too much or too little sleep, and weather. Sometimes the migraine occurs with no apparent “cause.”
Migraine patients have long been advised to try to identify personal headache triggers by looking for associations between their headaches and various suspected trigger factors. Patients are urged to keep a “headache diary” in which to note what they eat and when they get a headache, to look for correlations, and to try to avoid headache by avoiding factors they identify as triggers. Typically this advice is accompanied by a list of trigger factors.
[edit]
Food
Authors who in 2005 reviewed the medical literature[2] found that the available information about dietary trigger factors relies mostly on the subjective assessments of patients. Some suspected dietary trigger factors appear to genuinely promote or precipitate migraine episodes, but many other suspected dietary triggers have never been demonstrated to trigger migraines. The review authors found that alcohol, caffeine withdrawal, and missing meals are the most important dietary migraine precipitants. The authors say dehydration deserves more attention, and that some patients are sensitive to red wine. The authors found little or no demonstrated evidence that notorious suspected triggers chocolate, cheese, or that histamine, tyramine, nitrates, or nitrites normally present in foods trigger headaches. The artificial sweetener aspartame (NutraSweet®) has not been shown to trigger headache, but in a large and definitive study monosodium glutamate (MSG) in large doses (2.5 grams) was associated with adverse symptoms including headache more often than was placebo. The review authors also note that general dietary restriction has not been demonstrated to be an effective migraine therapy.
On the other hand, several headache clinics have had good results with individually tailored dietary restriction as a therapy. Dr. Ian Livingstone, director of the Princeton Headache Clinic, recommends eliminating the following common headache triggers from the diet: Aged Cheese, Monosodium Glutamate, Processed fish and meats containing nitrates (such as hot dogs), dark chocolate, aspartame, certain alcoholic beverages (including red wine), citrus fruits, and caffeine. After a period of a month or two, these foods can be reintroduced one at a time to determine their trigger potential for that individual. Adding a lot of the suspected trigger in a short time will generate a response that is easy to observe.
Dr. David Buchholz, who treats headaches as a neurologist at Johns Hopkins, has a longer list of suspected migraine triggers. Once again, he recommends eliminating the triggers from the diet altogether, and then reintroducing them slowly after many weeks to measure the effects. His list includes: Coffee (including decaf), chocolate, monosodium glutamate, processed meats and fish (aged, canned, preserved, processed with nitrates, and some meats which contain tyramine), cheese and dairy products (the more aged, the worse), nuts, citrus and some other fruits, certain vegetables (especially onions), fresh risen yeast baked goods, dietary sources of tyramine (including the foods listed above), and whatever gives you a headache.

Weather
Several studies have found some migraines are triggered by changes in weather. One study[3] noted that 62% of the subjects in the study thought that weather was a factor, in fact 51% were actually sensitive to weather changes. While those whose migraines did occur during a change in weather, often the subjects picked a weather change other than the actual weather data recorded. Most likely to trigger a migraine were, in order:
1. Temperature mixed with humidity. High humidity plus high or low temperature was the biggest cause.
2. Significant changes in weather
3. Changes in barometric pressure
Another study[4] studied whether chinook winds (warm westerly winds occurring in Alberta, Canada) are a migraine trigger. Many patients had increased incidence of migraines immediately before and/or during the chinook winds. The number of people reporting migrainous episodes during the chinook winds was higher on high-wind chinook days.
