While there is well-established research on foods that can exacerbate certain allergies, there isn't specific evidence that connects certain foods to increased severity in Deer Fly allergy symptoms. However, there are few kinds of food ingredients, that have been reported to generally worsen allergies symptoms in susceptible individuals such as:

Foods that can trigger histamine response:

• Alcohol: It's not just the sulfites in the alcohol that can exacerbate allergies, but also the alcohol itself can have an effect.
• Dried fruits: Dried fruits can sometimes contain sulfite preservatives which could exaggerate allergic reactions.
• Aged cheese: Aged cheese can often have high histamine levels, which can worsen allergy symptoms.

Foods that can cause Inflammation:

 

• Sugar: Consuming a lot of sugar can result in inflammation which might escalate allergic responses.
• Processed meats: Processed meats usually contain nitrates which might trigger inflammation.
• Refined carbs: Refined carbs can spike your blood sugar levels and instigate inflammation.

It's suggested to consult with a healthcare professional or an allergist for tailored advice to your specific situation and symptoms.
