Food sensitivities are often inherited. The difference between food allergies and food sensitivities has to do with the type of allergic reaction. This may range from immediate sinus congestion to the more dangerous anaphylactic reaction of restricted airway. Food sensitivities are actually allergic reactions, but I prefer to refer to them as sensitivities or intolerances to distinguish them from the more immediate allergic reactions. Food sensitivities are delayed reaction allergies that involve a diiferent type of antibody production, IgG. They can manifest hours after ingesting a certain food or possibly even days.
Food sensitivities are more elusive to detect.
Yes, but I think that is because I have more women patients than men. It is pretty evenly distributed between men and women. An estimated 35 million people suffer from food sensitivities. It is important to realize that food sensitivities can be classified as either cyclic or fixed. Cyclical are slowly developed by repetitive eating of a food.
