Re: Why,in a fair percentage of people does the nose run while eating

I can give a short answer as to why it may happen. It may be a vasomotor 
response with subsequent production of mucous. Perhaps a defense reaction 
against the temperature change. When I was in training this issue came up 
in a discussion on food allergies. Many times this will happen with dairy 
products. The lecturer, an allergy specialist, pooh poohed the idea of 
histamine induced rhinorrhea in this case. Now, some people can get a 
significant histamine response to cold or warm stimuli which would be a 
somewhat different approach then the vasomotor approach. Likewise certain 
people will have persistent allergy like symptoms but when tested  will 
not have specific allergies. Their reactions are then attributed to 
vasomotor rhinorrhea.
