Why Do I Get a Headache After Eating Pork?

You just enjoyed a delicious meal featuring juicy pork chops or bacon But within hours, your head is throbbing with a painful headache If this scenario sounds familiar, you’re probably wondering – why do I get a headache after eating pork?

Headaches after eating pork aren’t uncommon. The culprits behind “pork headaches” range from nitrates to allergies. Let’s explore the science and triggers, so you can avoid headaches and continue enjoying the savory taste of pork.

Common Causes of Headaches After Eating Pork

There are a few key reasons you may develop a headache after consuming pork products:

Nitrates/Nitrites

Many processed pork items like bacon, ham, hot dogs and lunch meats contain nitrates and nitrites. These compounds preserve color and extend shelf life. But they can provoke headaches in sensitive people by widening blood vessels.

Once you ingest nitrates/nitrites they convert into nitric oxide. This chemical helps regulate blood flow. But in excess it dilates blood vessels and disrupts circulation. For those prone to vascular headaches, these changes commonly trigger migraine-like symptoms.

To avoid nitrate/nitrite headaches, choose fresh, unprocessed pork and pork products labeled “no nitrates/nitrites added.”

High Tyramine

Tyramine is an amino acid occurring naturally in aged, fermented and smoked foods. High-tyramine foods include aged cheeses, processed meats like salami, and fermented items like soy sauce.

Tyramine alters blood flow and causes blood vessels to constrict. In those prone to migraines, tyramine can trigger severe, throbbing headaches. Pork products like bacon, pepperoni and smoked ham contain tyramine.

To prevent tyramine-induced headaches, limit cured meats and aged, fermented foods. Enjoy fresh pork instead of highly processed versions when possible.

Hormones

Fatty foods like pork can prompt release of hormones that dilate blood vessels, altering blood flow to the brain. These fluctuations commonly trigger vascular headaches in susceptible people.

Choosing leaner cuts of pork may help, as will limiting portion sizes. Avoid eating large, high-fat pork meals which can overwhelm the body with fat-released hormones.

Allergy

In rare cases, pork allergies cause adverse reactions like headache, hives, breathing issues and anaphylaxis. The body misidentifies proteins in pork as harmful and releases histamine, prompting headache and other symptoms.

If you suspect a pork allergy, see an allergist for allergy testing. Strictly avoiding pork and products containing pork derivatives is vital with a confirmed pork allergy.

MSG

Monosodium glutamate (MSG) is a flavor enhancer added to many processed pork products. MSG may potentially trigger headaches in sensitive individuals, although research is still preliminary.

See if avoiding products containing MSG alleviates headaches. Check labels for MSG, as it may be hidden in ingredients like yeast extract, hydrolyzed proteins and autolyzed yeast.

Other Possible Contributors

Additional factors that may set the stage for headaches after eating pork include:

• Dehydration – can exacerbate food-related headaches

• Stress – changes brain chemistry and blood flow

• Sleep deprivation – disrupts neurotransmitters

• Hormonal changes – fluctuations may impact headaches

• Certain medications – some prescriptions provoke headaches

• Food additives – preservatives and flavor enhancers like MSG

• Fasting – infrequent meals alter metabolism

Paying attention to lifestyle factors can help identify if elements besides pork are contributing. Keeping a headache diary tracking foods, habits and symptoms helps pinpoint headache triggers.

Tips to Prevent Headaches After Eating Pork

If you regularly experience headaches after eating pork, try these preventive tips:

• Choose fresh, additive-free pork – avoid processed versions high in nitrates/nitrites.

• Read labels and avoid MSG – watch for hidden forms like yeast extract.

• Eat a balanced diet – skip large, fatty pork meals that alter hormones.

• Stay hydrated – drink water before, during and after meals.

• Limit tyramine-rich foods – steer clear of aged, fermented and smoked items.

• Manage stress – yoga, meditation and massage release tension.

• Get adequate sleep – aim for 7-9 hours nightly.

• Time pain relievers appropriately – take meds after eating to reduce food interactions.

Paying attention to food choices, lifestyle habits and timing of symptoms helps determine if pork specifically triggers your headaches. If changing pork products, cooking methods and portions still brings on headaches, discuss other possible causes with your doctor.

In some cases, taking a magnesium supplement or prescription medication helps prevent pork-related headaches. Consulting a neurologist who specializes in headaches gives you the best shot at effective treatment.

Warning Signs to Seek Medical Care

Schedule an urgent medical visit if you experience:

• Headaches accompanied by confusion, speech issues or vision changes – may signal stroke

• Headaches with fever and neck pain/stiffness – could indicate meningitis

• Sudden, severe headache unlike previous headaches – may be aneurysm

• New headache pattern after age 50 – discuss causes like mass or bleed

While pork-related headaches are usually not dangerous, any sudden change in headache symptoms warrants prompt medical evaluation. Don’t ignore accompanying neurological symptoms, which may indicate something serious.

The Takeaway

If you’re prone to headaches, pay attention to symptoms you experience after eating pork products. While pork isn’t inherently unhealthy, it contains compounds that may trigger vascular headaches in sensitive people. Avoiding nitrate/nitrite-cured pork and staying hydrated helps fend off headaches for many pork lovers. But if dietary tweaks don’t resolve your symptoms, seek professional medical advice. Getting to the root of your “pork headaches” leads to long-term relief.
