A member asked:
How long after eating allergic food do you have a reaction?
A doctor has provided 1 answer
Food allergy timing: You can react in minutes, or it can take many hours. The faster reactions tend to be the most severe and potentially dangerous, even life-threatening, but occasionally, even late reactions can be very dangerous, as in reactions to alpha-gal (http://allergytomeat.Wordpress.Com/frequently-asked-questions/). Atopic dermatitis reactions to foods may not start for a couple of days; last weeks.
