Nutrition for Migraine

Migraines affect around one in seven people worldwide and are much more than "just a headache." They are a complex neurological condition that can significantly affect work, family life and quality of life. While medication plays an important role in treatment, research suggests that nutrition and lifestyle strategies can help reduce the frequency, severity and duration of migraine attacks for many people.

What is a Migraine?

A migraine is a neurological disorder characterised by recurrent attacks of moderate to severe headache, often accompanied by a range of other symptoms. Unlike a tension headache, migraines involve changes in the brain and nervous system that can affect many different parts of the body.

Common symptoms include:

• Moderate to severe throbbing headache, often affecting one side of the head

• Nausea and vomiting

• Sensitivity to light, sound and/or smells

• Visual disturbances or aura in some people

• Dizziness or vertigo

• Fatigue and difficulty concentrating

Migraine attacks can last anywhere from four hours to three days, and many people experience symptoms before and after the headache itself. Women are approximately three times more likely to experience migraines than men, largely due to the influence of hormonal fluctuations.

What Causes Migraines?

The exact cause of migraine is not fully understood, but it is recognised as a complex neurological condition involving changes in brain activity, nerve signalling and the release of inflammatory chemicals. Genetics also play an important role, meaning some people are naturally more susceptible than others.

Rather than being caused by one single factor, migraines are thought to develop when a person's migraine threshold is exceeded. You can think of this threshold as your brain's ability to cope with internal and external stressors. Throughout the day, factors such as poor sleep, stress, hormonal changes, dehydration or skipping meals may gradually lower this threshold. When enough factors combine, they can trigger a migraine attack.

This helps explain why a particular food, drink or situation may seem to cause a migraine one day but have no effect on another. Often, it isn't one trigger acting alone but the combination of several factors that pushes you beyond your individual threshold.

Understanding this concept is important because it shifts the focus away from trying to identify a single culprit and towards improving the overall factors that support brain health and reduce the likelihood of an attack.

Common Migraine Triggers

Migraine triggers vary considerably from person to person, and not everyone will be affected by the same factors. Keeping a migraine diary can help identify your own patterns over time. Some of the most commonly reported triggers include:

• Hormonal changes: Many women notice migraines around menstruation, ovulation, pregnancy or menopause. Fluctuations in oestrogen, particularly a rapid fall in levels before a period, are a well-recognised trigger for menstrual migraine.

• Stress: Stress is one of the most frequently reported migraine triggers. Interestingly, migraines often occur during the "let-down" period after a stressful event rather than during the stressful situation itself.

• Poor sleep: Both insufficient sleep and sleeping for longer than usual have been associated with an increased risk of migraine. Maintaining a regular sleep routine may help reduce attacks.

• Skipping meals: Going for long periods without eating can lead to changes in blood glucose levels, which may trigger migraines in susceptible individuals.

• Dehydration: Even mild dehydration may contribute to migraine by affecting blood flow, electrolyte balance and brain function.

• Weather and heat: Some people are particularly sensitive to heatwaves, high humidity or changes in barometric pressure. Although the research is mixed, weather changes are commonly reported as a trigger by people living with migraine.

• Bright lights and strong smells: Flashing lights, prolonged screen use, strong perfumes and certain chemical odours can trigger migraines in some individuals.

• Alcohol and caffeine: Alcohol, particularly when combined with dehydration or poor sleep, may contribute to migraine in some people. Caffeine has a more complex relationship with migraine as it can help relieve symptoms for some people, while excessive intake or caffeine withdrawal may trigger attacks in others.

• Certain foods: Although foods such as chocolate, aged cheese, processed meats and foods containing monosodium glutamate (MSG) are often blamed for migraines, research suggests true food triggers are less common than many people believe. Rather than eliminating foods unnecessarily, it is usually more helpful to identify consistent patterns using a migraine diary before making significant dietary changes.

Recording your migraines in a migraine diary alongside factors such as sleep, stress, meals, hydration, menstrual cycle, exercise and weather can help identify personal patterns and guide management.

Nutrition Tips for Migraine Prevention

Can Nutrition Help Prevent Migraines?

There is no single "migraine diet" that works for everyone. However, research suggests that nutrition can influence many of the processes involved in migraine, including blood sugar regulation, hydration, inflammation and nerve function. Rather than focusing on eliminating lots of foods, the evidence supports building consistent, healthy eating habits and correcting nutritional deficiencies where appropriate.

Eat Regular Meals

Skipping meals is one of the most common migraine triggers. Aim to eat every three to four hours where possible and avoid prolonged fasting.Including a source of protein with each meal helps maintain more stable blood glucose levels. Good sources include eggs, fish, chicken, yoghurt, tofu, beans, lentils and nuts.

Choose fibre-rich carbohydrates such as oats, wholegrains, vegetables and fruit to provide a steady source of energy throughout the day.

Stay Hydrated

Aim to drink enough fluid throughout the day, particularly during hot weather, exercise or illness. If you sweat heavily through exercise or heat, replacing electrolytes as well as fluids may also be beneficial.

Eat More Omega-3 Fats

Omega-3 fatty acids have anti-inflammatory properties that may help reduce migraine frequency. Aim for one to two portions of oily fish each week, including salmon, sardines or mackerel. Vegetarians and vegans may wish to consider an algae-derived EPA and DHA supplement.

Don't Restrict Foods Unnecessarily

Many people eliminate large numbers of foods in the hope of preventing migraines. Unless a clear and consistent relationship has been identified, unnecessary food restrictions may reduce dietary quality without improving migraine symptoms. A migraine diary is often more useful than broad elimination diets.

Keep Caffeine Consistent

Rather than avoiding caffeine completely, aim for consistency. Large day-to-day changes in caffeine intake appear more likely to trigger headaches than moderate, regular consumption.

Lifestyle Tips for Migraine Prevention

Prioritise Sleep

Aim for seven to nine hours of sleep each night and try to maintain consistent bedtimes and waking times, even at weekends.

Manage Stress

Techniques such as mindfulness, yoga, breathing exercises and cognitive behavioural therapy (CBT) have all been shown to help reduce migraine frequency in some individuals.

Stay Cool During Heatwaves

If heat is a trigger, increase your fluid intake, avoid prolonged sun exposure, use fans or air conditioning where possible and continue eating regular meals even if your appetite is reduced.

Many people also find that cooling the head or neck provides relief during a migraine attack. Cooling may help by reducing pain signalling, calming overactive nerves and causing blood vessels near the skin to constrict, although the exact mechanism isn't fully understood.

Cooling options include:

• Reusable migraine cooling caps or headache hats such as MyHalo

• Ice packs wrapped in a towel

• Cooling gel packs applied to the forehead or back of the neck

  
  

FL-41 Migraine Glasses

If bright light, computer screens or fluorescent lighting trigger your migraines, specially tinted FL-41 lenses may help. Unlike standard sunglasses, FL-41 lenses filter specific wavelengths of blue-green light that are thought to increase light sensitivity in people with migraine. Several studies have shown they may reduce both migraine frequency and light sensitivity in some individuals, particularly those who experience photophobia.

Supplements

Several supplements have been studied for migraine prevention.

Magnesium

Magnesium has the strongest evidence of all the nutritional supplements used for migraine prevention. It plays an important role in nerve signalling, muscle relaxation and maintaining normal brain function. Research suggests that taking magnesium daily may reduce migraine frequency, particularly in people with menstrual migraine or migraine with aura. Benefits are usually seen after several weeks to a few months of consistent use, rather than when taken only at the onset of a migraine attack. Magnesium glycinate and magnesium citrate are generally well absorbed and less likely to cause digestive side effects than magnesium oxide.

Riboflavin (Vitamin B2)

Studies suggest that 400 mg daily may reduce migraine frequency after around three months by supporting energy production within brain cells.

Coenzyme Q10

CoQ10 also supports cellular energy production, and some studies suggest that 300 mg daily may reduce migraine frequency.

Vitamin D

If you are deficient in vitamin D, correcting this may help reduce migraine frequency. Ideally, vitamin D levels should be tested before starting higher-dose supplementation.

Always speak to your healthcare professional before starting supplements, particularly if you take prescription medication or have underlying health conditions.

Final Thoughts

Migraines are a complex neurological condition influenced by genetics, hormones, lifestyle and environmental factors. Although there is no single food or supplement that can prevent migraines, building healthy habits such as eating regular meals, staying hydrated, prioritising sleep and managing stress may help reduce the frequency and severity of attacks.

Because migraine triggers vary between individuals, keeping a migraine diary can help identify your own patterns and guide personalised management. If your migraines are becoming more frequent, changing in pattern or affecting your quality of life, speak to your GP or healthcare professional for further assessment.
