What Foods Cause Headaches

Headaches--from mild to debilitating--affect almost everyone at one time or another. There are two types of headaches, tension and migraine. Migraine headaches affect far more women than men. According to the Mayo Clinic, headaches can be caused by food allergies and sensitivities. Some foods are common headache triggers. Learn what yours are by keeping a food diary.


MSG


Read labels carefully; MSG is not just a Chinese food additive. MSG is a calcium channel opener---it constricts blood vessels, a primary cause of headaches.


Copper


Wheat germ, shellfish and nuts contain high levels of copper that can cause headaches in sensitive people. Beware of citrus fruits---they increase copper absorption.


Caffeine


Too much caffeine can cause headaches, but too little---if you're a coffee fiend---can cause them, too. Don't overdo it with the coffee, and cut back slowly if you're trying to quit.


Tryptophan


Tryptophan is an amino acid that is found in high protein foods. It is converted by the body to serotonin, a process that can trigger a migraine.


Tyramine


Tyramine is a substance found in many foods including cheese, yogurt and smoked fish. Some people cannot break this substance down fully, and it can cause headaches.


Nitrates


Hot dogs and cured meats contain nitrates. Nitrates can dilate blood vessels, causing---you guessed it---a headache.
