Why does my nose always run when i eat even non spicy foods?

Vasomotor rhinitis: This is a non-allergic rhinitis that can be triggered by multiple causes, including spicy food, stress, temperature extremes, and pungent odors. The "non-spicy" food may have ingredients that have this effect, as some spices can do that without tasting "spicy.".

Runny nose Eating: U may have something called vasomotor rhinitis. It's triggered by temperature of food for some people.

Neural response: This phenomenon is usually not allergy. It is most commonly the result of a central triggering of the vagus nerve. This nerve innervates both the blood vessels and the mucus glands of the nasal mucosa. It is possible that an anti-cholinergic nasal spray might control the rhinnorhea (runny nose). It is a perfectly benign condition.
