Headaches are a common ailment that can range from mild to debilitating. While there are many causes of headaches, certain foods have been known to trigger them. If you suffer from headaches, avoiding these 10 foods may help.

1. Alcohol

Alcohol is a common trigger of headaches. Beer, wine and liquor can all cause headaches, but red wine is particularly known to do so. This may be due to the presence of tyramine, which can cause blood vessels to dilate and lead to headaches.

2. Caffeine

Caffeine is a double-edged sword when it comes to headaches. It can provide relief for some people, but can also be a trigger for others. If you consume too much caffeine, or are sensitive to it, you may experience headaches as a result.

3. Aged Cheeses

Aged cheeses, such as blue cheese, cheddar, and parmesan, contain tyramine, which can trigger headaches in some people. If you notice that cheese seems to be a trigger for you, try avoiding aged varieties.

4. Processed Meats

Processed meats, such as hot dogs, bacon, and deli meats, are high in nitrates, which can dilate blood vessels and cause headaches. If you frequently experience headaches, try cutting back on these types of meats.

5. Chocolate

Chocolate contains two headache triggers: caffeine and tyramine. While small amounts of chocolate may not cause headaches, consuming too much can be a problem for some people.

6. Citrus Fruits

Oranges, lemons, and other citrus fruits contain a high level of histamines, which can contribute to headaches. If you notice that citrus seems to trigger your headaches, consider limiting your intake or avoiding it altogether.

7. Artificial Sweeteners

Artificial sweeteners, such as aspartame and saccharin, have been known to trigger headaches in some people. If you consume a lot of diet soda or other artificially-sweetened products, try cutting back and see if it makes a difference.

8. MSG

Monosodium glutamate (MSG) is a common food additive that can trigger headaches in some people. It is often found in Chinese food, but can also be present in other packaged and processed foods.

9. Nuts

Nuts, especially peanuts, almonds, and walnuts, contain high levels of tyramine. If you are sensitive to this compound, consuming nuts may contribute to your headaches.

10. Avocados

Avocados are a healthy and delicious food, but they can also trigger headaches in some people. This may be due to their high levels of histamines and tyramine.
