Coughing is a natural reflex to clear foreign substances from the respiratory tract. However, "chronic cough"—defined as coughing lasting more than 8 weeks in adults—usually has more complex causes than a common cold. Medical data indicates that the main causes of chronic cough often include allergies, asthma, acid reflux, continuous exposure to pollution and PM 2.5 dust, as well as long-term effects following respiratory infections.
Besides treating symptoms, "eating habits" are also key factors directly affecting the bronchi and throat. Consuming inappropriate foods may prolong inflammation and irritation.
To reduce irritation and help the body recover faster, those with chronic cough should avoid the following five common food groups.
Popular dishes like fried chicken, crispy pork, or foods cooked with large amounts of oil can easily irritate the throat. Additionally, high fat content may increase inflammation, slowing relief from irritation.
For people with allergies or sensitive airways, extremely cold temperatures can cause bronchial constriction, worsening coughing—especially when drinking very cold water while already having throat irritation.
Spicy or highly sour foods are risk factors for acid reflux. When stomach acid flows back up into the esophagus and throat, it causes severe irritation, which is a hidden cause of chronic dry cough in many people without them realizing it.
Consuming too much sugar not only increases obesity risk but also triggers inflammation in the body, weakening the immune system and potentially slowing recovery from coughs and colds.
Although dairy products like cow's milk have benefits, some individuals with cough and mucus may find that milk thickens mucus, making it harder to clear from the throat, leading to more frequent throat clearing or coughing.
Chronic cough is a warning sign that should not be ignored. Changing eating habits by avoiding fried foods, cold drinks, spicy foods, sweets, and dairy products in some cases can help reduce irritation and alleviate symptoms initially. However, if coughing persists beyond 3-4 weeks or is accompanied by other symptoms such as coughing up blood, weight loss, or shortness of breath, it is important to see a specialist promptly for accurate diagnosis and treatment.
