Does Eating Sweets Cause Coughing?

Sugar can cause cold and allergy type symptoms such as a constant runny nose, cough, excessive mucus, and signs of sinus infection.

Why do I get cough after eating sweets?

But sugar consumption is a sure-shot way of making your cough worse. As per a study published in Frontiers in Immunology in 2017, increased sugar intake can suppress the immune system, especially when fighting viral infections. This applies to the common cold too, so make sure you stay away from those desserts.

What foods trigger cough?

It should come as no surprise that spicy foods are one of the most common culprits, because of the ingredient capsaicin. Foods high in citric acid (like lemons and limes), as well as acetic acid (found in things like vinegar or pickled vegetables), have also proven to tickle our cough centers.
