Coughing profusely after consuming cashews, even in the absence of a nut allergy, can stem from several factors that do not necessarily involve an allergic reaction. Here are some potential reasons:

1. Irritation or Sensitivity: For some people, certain foods, including cashews, may irritate the throat or esophagus, leading to coughing. This irritation may be due to the natural oils or substances present in the nut (source: Medical News Today).

2. Improper Chewing or Portion Size: If cashews are not chewed thoroughly or if they are consumed in large pieces, they can create a sensation of something lodged in the throat, which may trigger a cough reflex. Ensuring that you chew cashews properly or consume smaller pieces may help alleviate this issue (source: MevaBite).

3. Dryness or Lack of Hydration: Eating dry foods like nuts without sufficient hydration can lead to throat irritation and coughing. It's essential to stay hydrated, especially when consuming dry snacks (source: MevaBite).

4. Oral Allergy Syndrome (OAS): Even in the absence of a full-blown allergy, some individuals may experience mild, cross-reactive symptoms due to sensitivities. This can occur in individuals who have pollen allergies, where certain proteins in nuts can trigger similar responses in the mouth and throat (source: Thermo Fisher).

If your coughing persists or is accompanied by other concerning symptoms, it may be advisable to consult a healthcare professional for further evaluation and guidance.
