foods that irritate the throat
Citrus and Acidic Foods. Stay away from acidic and citrus foods like tomatoes, oranges, grapefruit, limes and lemon. The acids found in these foods can irritate and worsen your sore throat. Instead of having citrus fruits, choose fruits that are soothing to the throat such as bananas, melons, kiwi and peaches.
According to dietitian Ilyse Schapiro on the Huffington Post website, fatty foods are harder for your body to digest and can suppress your immune system, which can worsen cold symptoms such as a sore throat. Deep-fried foods often have breading that is dry and rough, which can further irritate your throat.
