For patients with colds and coughs, it is essential to be cautious about certain foods in daily life, which are best avoided. For example, spicy, greasy, raw, cold, and stimulating foods should be avoided. Also, carbonated beverages, strong tea, coffee, or alcoholic drinks should be avoided to prevent worsening the cold and cough symptoms. Additionally, some tropical fruits like mango, durian, longan, and lychee should also be avoided. These fruits are warm in nature and may exacerbate phlegm production, aggravating the cold and cough. During a cold and cough, it is advisable to eat a bland diet, such as properly consuming apples, pears, bananas, grapefruits, and oranges. It's also important to drink plenty of water, which can help soothe the throat.
