Introduction

In general, it is usually not recommended to eat crayfish during a coughing episode, as it may worsen respiratory tract irritation. If coughing persists for more than one week or is accompanied by symptoms such as fever or difficulty breathing, prompt medical consultation is needed to rule out infectious or allergic causes. Crayfish are rich in protein, and excessive consumption may increase the burden on the gastrointestinal system, leading to gastroesophageal reflux and irritating the throat, thereby triggering or worsening coughing.

Generally, it is not recommended to eat crayfish during a coughing episode, as it may exacerbate respiratory tract irritation. If coughing persists for more than a week or is accompanied by symptoms such as fever or difficulty breathing, prompt medical attention is needed to identify potential infections or allergic causes. Detailed explanations are as follows:

Crayfish are rich in protein, and excessive consumption may increase the gastrointestinal burden, leading to gastroesophageal reflux, which can irritate the throat and trigger or worsen coughing. Ingredients used in heavily seasoned preparations, such as chili peppers and Sichuan peppercorns, contain compounds like capsaicin and sanshool that directly irritate the respiratory mucosa, exacerbating cough symptoms.

Crayfish are also common allergens; their foreign proteins may trigger allergic coughing or asthma attacks. If the cough is allergy-related, consumption may intensify airway hyperresponsiveness, resulting in symptoms like wheezing and chest tightness.

During a cough, it is recommended to eat steamed or boiled foods such as steamed fish and porridge. Oranges and broccoli can also be consumed to help boost immunity. Additionally, drinking plenty of warm water, pear juice, or honey water may help thin mucus secretions and relieve throat discomfort.
