Processed meat
Processed meats like sausages and hot dogs contain preservatives and additives that can cause inflammation and aggravate cough and cold symptoms.

Avoid sugary foods like candy, cakes and pastries when you have a cold or cough because they can suppress your immune system, making it harder for your body to fight off infection.
Fried food
Fried foods like french fries and fried chicken can be difficult to digest, leading to inflammation and aggravating cough and cold symptoms.
Foods high in salt
Consuming foods high in salt such as processed snacks, pickles, and canned soups can increase mucus production and worsen cough and cold symptoms.
