Thus, most food-induced headaches occur as a result of food intolerance, which occurs due to your body’s biochemistry.
In true food allergies, your immune system produces chemicals histamine and immunoglobulin E (IgE) in response to the allergen that gives rise to dizziness and nausea.
Much research hasn’t been conducted on food intolerances, but they can cause serious health problems. Food allergies headaches can be triggered by several foods, but the most common culprits are:
- Dairy products (milk, eggs, cheese, butter, ice cream)
- Tree nuts (cashews, almonds, pine nuts, pistachios, walnuts, hazelnuts)
- Corn, wheat, soy
- Plants milk
- Cane sugar and other sources of sugar
- Seafood (fish, shellfish, shrimps, sushi)
Besides these, you may have nausea and headaches after eating something spicy, or sugary.
