Wahoo pollen, produced by the Wahoo tree, is present in several regions across the USA. The plant is indigenous to the Eastern and Central parts of the country. Particular hotspots include areas of the Midwest, through to Pennsylvania and extending southwards into Florida. It can also be found on the West Coast, particularly in California. Despite its prevalence in these regions, Wahoo does not broadly distribute its pollen; hence, it is not typically considered a chief contributor to hay fever reactions.

Wahoo Tree Distribution in Detail

• Midwest to Pennsylvania: This widespread region is a significant habitat for Wahoo trees and hence a potential source of Wahoo pollen.
• Southern Extension: The plant extends southwards, reaching down into Florida, where its pollen may also be found.
• California: Wahoo trees are also present on the West Coast, particularly in California, adding another potential pollen source.

Food items that worsen Wahoo Pollen Allergy

Many people with pollen allergies can also develop symptoms when they eat certain fruits, vegetables, or nuts. This phenomenon is called oral allergy syndrome (OAS) or pollen-food syndrome. Individuals with Wahoo pollen allergy may experience an allergic reaction to certain food items that have proteins similar to those found in Wahoo pollen.

• Apples and Pears: These fruits are known to exacerbate the symptoms of Wahoo pollen allergy. Their protein structure is similar to Wahoo pollen causing the immune system to react.
• Nuts: Especially almonds, hazelnuts, and walnuts. They have a protein structure similar to Wahoo pollen which can lead to worsening of allergy symptoms.
• Stone fruits: Such as cherries, peaches, plums, and apricots can aggravate Wahoo pollen allergies.
• Raw vegetables: Particularly carrots, celery, and parsley. Their raw state can trigger an allergic reaction in individuals with Wahoo pollen allergy.
• Spices: Certain spices including coriander, fennel, and anise can induce pollen-food syndrome, worsening Wahoo pollen allergy symptoms.

It's worth noting that these reactions usually occur when these foods are eaten raw. Cooking or baking them may alter the allergenic proteins, thereby reducing or even eliminating the allergic reaction. However, each individual is unique, and reactions can vary. If you have a Wahoo pollen allergy and suspect that certain foods are causing your symptoms to worsen, it is a good idea to discuss this with your allergist or dietitian who can provide guidance personalized to your situation.
