Migraine and Diet —— Common Triggers and What Actually Helps in Kathmandu

Diet is a commonly reported migraine trigger, but the relationship between food and migraine is highly individual. Systematic identification through a headache diary is more useful than blanket elimination of food groups.

Common dietary triggers: Alcohol —— particularly red wine —— is one of the most consistently reported dietary triggers, often producing headache within hours. Aged cheeses, processed meats (containing nitrates and nitrites), monosodium glutamate (MSG), artificial sweeteners such as aspartame, and excessive caffeine or caffeine withdrawal are frequently cited. However, the evidence for many of these is based on patient reporting rather than controlled trials, and trigger thresholds vary between individuals and even within the same person over time.

Skipping meals and dehydration: Missing meals causes drops in blood sugar that can trigger migraine in susceptible individuals. Dehydration is a well-established trigger —— even mild dehydration (1——2% body weight loss) can lower the migraine threshold. In Kathmandu's warm climate, fluid intake often lags behind losses, making dehydration a particularly relevant contributor. Regular meal timing and consistent hydration are among the most actionable dietary strategies.

The role of caffeine: Caffeine has a paradoxical relationship with migraine. Small amounts can enhance the effectiveness of acute pain medication, but regular excessive intake (more than 200 mg/day, roughly two cups of strong coffee) can contribute to medication-overuse patterns. Sudden caffeine withdrawal after habitual use can trigger rebound headache. Consistency matters more than elimination.

Headache diary approach: A structured diary recording food and drink intake alongside headache occurrence for 4——8 weeks reveals individual patterns better than generic food lists. Note what was eaten and when, how much water was consumed, whether meals were skipped, and any headache within 24 hours. This record, reviewed at Kathmandu Neurology Clinic with Dr. Jitendra Prasad Yadav, identifies genuine triggers versus coincidence.

What evidence says about elimination diets: Systematic elimination of multiple food groups without clinical guidance can lead to nutritional deficiency, unnecessary anxiety, and diminished quality of life. Evidence supports eliminating only foods that consistently and reproducibly trigger attacks —— not foods that are merely suspected. When elimination is considered, it should be done one food group at a time over a defined period, under medical supervision, with reintroduction to confirm the trigger.

Practical tips: Eat regular meals —— do not skip breakfast. Maintain consistent hydration —— aim for at least 8 glasses of water daily, more in hot weather or with physical activity. Limit caffeine to a consistent moderate amount and avoid sudden increases or decreases. Read food labels for MSG and artificial sweeteners when eating processed foods. Do not eliminate entire food categories without guidance —— bring your diary to consultation for individualised assessment.
