How Can I Find Information About Allergens In My Food
Elimination diet: Try an elimination diet. You'll remove suspected allergens like wheat or dairy for a week, if symptoms improve, try reintroducing them one at a time in 2-3 day intervals. If you react negatively to a food, you may have a sensitivity to that food type. You can also see a provider for "rast" blood testing. ...Read moreSee 1 more doctor answer
Yes: Allergens are most commonly a protein although other molecules can sometimes be recognized as an allergen. So, yes most foods are allergens. An allergic reaction is caused by your immune system recognizing those unique proteins and causing a reaction. Luckily it is fairly rare, so other foods don't cause a reaction and you can eat them. ...Read moreSee 1 more doctor answer

After eating a problem food allergen, how long does it take to show up in body symps? And how long does it take to exit system? Thanks Dr!

I have suddenly developed many food allergies (see profile). I've been on a strict organic diet with no allergens and still having problems. Why?
I want to go get a blood test for allergies. Will this assess for all types of allergens? Will it tell if I'm allergic to food dyes?
Uncertain: Every single test needs be interpreted with the history and physical findings in context. Food dye allergy. Other than to red carmine dye, is very rare if non-existent although it was in vogue over 40 years ago. ...Read more
I've never had food allergies & tested neg for them, but do have eczema & chronic hives. Does this mean i'll react to big allergens like nuts & fish?
Not necessarily: In fact, your own experience with eating nuts and fish is a much more reliable indicator of whether you're actually allergic than the results of skin testing will be. I think your allergist will tell you the same thing. The best way to determine whether your skin issues are due to allergy is a few weeks' trial of an elimination diet. Ask about it. ...Read moreSee 2 more doctor answers

Can a food intolerance cause itching? And related, can a food allergy not respond to small amounts of the allergen (fine at <5 g, sick at >30)?
Yes and yes: Food allergy is not a trivial matter. Food allergy can change from itching one time to fatal anaphylaxis the next. It is important to have allergy testing, have a consultation with an allergist, avoid all foods you are allergic to, have an epipen (epinephrine) and an emergency action plan handy, and carefully examine the contents of everything you eat for contamination with the allergy triggers you have. ...Read more
Could someone with a food allergy possibly breathe something they are allergic to and have a reaction with hives? My son is allergic to something so we have been avoiding a lot of the most common allergens but is still breaking out in hives.
Allergist: Finding the cause of recurrent hives is very elusive and in these cases an allergist is best qualified to do the investigation. The offending agent could be internal or external including temperature change, exercise, etc. While waiting for the allergist's appointment, the pediatrician may prescribe an antihistamine for symptom relief. ...Read moreSee 1 more doctor answer
Does risk for anaphylaxis vary with type of allergen from immunotherapy? Example: pollen, stings, mites, cat, food, etc..
Complex: Risk of anaphylaxis from immunotherapy depends on many factors: identifying the allergens causing the symptoms, severity of symptoms, whether well controlled prior to start of therapy, choosing the right allergens and right concentrations, assessment at each visit prior to administration of therapy, and observation for at least 30 minutes. Very rare in the hands of a competent allergist, good luck ...Read more

I am breastfeeding a 7 months old baby with lots of food allergies e.g. egg, milk, wheat and corn. How long do these allergens stay in my breast milk?
Breast milk: Many pediatricians and pediatiric clinics assign the diagnosis of "foor allergies" as a cause of "colic" or poor feeding by an infant. It is possible that no "true allergies" have occurred, and if your infant is thriving (putting on predicted weight) it is unlikely that your breast milk is creating a problem. Ask a pediatric dermatologist for advice if your infant is not growing appropriately. ...Read more
