Discover the top five foods that can aggravate nasal polyp symptoms and learn strategies to manage dietary triggers effectively. This guide highlights foods like dairy, legumes, tomatoes, sugar, and red meat that may worsen nasal congestion and inflammation. By understanding these dietary influences, individuals can improve symptom control and maintain better sinus health through mindful eating habits.

Nasal polyps are non-cancerous growths that develop inside the nasal passages and sinuses. While small polyps often cause no symptoms, larger ones can block airflow, leading to difficulty breathing. Besides medical approaches, diet significantly impacts nasal polyp management and inflammation prevention. Certain foods may exacerbate symptoms or promote sinus infections. Recognizing these foods can help individuals better control their condition and improve overall comfort.

Below are five dietary items to limit or avoid for reducing nasal polyp discomfort.

Milk and Dairy Products
Dairy consumption can increase mucus production, worsening nasal congestion. Individuals allergic to dairy proteins might be more prone to developing polyps. Reducing intake of milk, cheese, and yogurt can alleviate symptoms during flare-ups.

Legumes and Salicylates
Although healthy, beans and lentils contain salicylates that may trigger allergic reactions and sinus inflammation in sensitive individuals. Foods like cauliflower, pickled vegetables, strawberries, watermelon, oats, corn, and herbs such as rosemary have high salicylate levels.

Tomatoes and Histamine-rich Foods
Tomatoes naturally contain histamine, which can accumulate and cause sneezing, congestion, and breathing issues. Other high-histamine foods include processed meats, avocados, eggplants, dried fruits like raisins and apricots, aged cheeses, chocolates, and wine.

Sugar and Processed Foods
Diets rich in refined sugars—found in sweets, candies, chocolates, and sugary drinks—can promote inflammation and worsen sinus symptoms. Limiting these foods helps manage discomfort.

Red Meat
Excessive consumption of beef, lamb, or pork can increase mucus production, leading to more congestion and inflammation. Consuming red meat in moderation benefits those with nasal polyps or sinus issues.
