Not very much: The fodmap elimination diet is designed for people with irritable bowel syndrome (ibs). It's goal is to reduce sugars and short-chain carbohydrates in the diet. The major overlap is with wheat as most of the other foods avoided in this diet are fruit & vegetables that are not common food allergy offenders. ...Read more
Loaded Question: To some degree they may be. For example in peanut allergic children subsequent sibs are probably at a higher risk than the general population for peanut allergy. However, the genetics of allergic disease is very complex and one generally passes on the ability to be allergic rather than a specific allergy. ...Read moreSee 1 more doctor answer
Mechanism: Food allergies are mediated by the ige antibody and it takes only a small amount to lead to a severe even anaphylactic allergic reaction and rarely death. Food intolerance is GI symptoms of bloating, gassy, crampy belly pain and diarrhea after eating usually larger amounts of a food. Intolerances are more common (like lactose intolerance) and are not mediated by ige antibody and not life ending. ...Read more
Allergic contact: Allergic contact dermatitis occurs when your skin comes in contact with substances that your skin is sensitive or allergic to. The reaction usually appears within 24-48 hours after exposure to the allergen. Symptoms that are common include redness, itching and swelling. Sometimes blistering and weeping of the skin also develop. What you are allergic to is determined by your genes, not foods. ...Read moreSee 1 more doctor answer
Gluten: Gluten is in wheat, barley, and rye. Therefore, it is in any foods or drinks that use these as ingredients. Some foods are pretty obvious like typical breads, pizza, pasta, cakes, and cookies. You need to be aware that gluten is in most beers, soy sauce, and many sauces. Anything breaded typically has gluten. ...Read more
If the oral allergy syndrome is due to x-reactions between homologous proteins in ingested food and aero-allergens why aren't food skin tests +?
Too complex...?!: The gut is both an immune privileged site and responds adversely (and often unpredictably) to ingested materials (e.g. Bacteria, food, dirt, etc.). There may be too many variables to easily answer your question. A case in point is eosinophilic esophagitis. Sadly, given our knowledge gap, too many patients take too many supplements or exclude too many products for questionable reasons. ...Read moreSee 2 more doctor answers

Yes: It usually is a protein in the food that causes the food allergies. Protein, meaning the specific part of a food that triggers your immune system. For example: milk allergy may be because of the casein protein in the milk. There also may be allergies to the carbohydrate unit of the meats but that is rare and presents differently. Best be evaluated by an allergist to help you clarify your allergy. ...Read more
Fish protein allergy: Most allergens are proteins, and the allergens in shellfish that set off allergic people are no exception. These are usually unique to the particular species of fish, but some cross-reactivity is possible. In the case of shrimp, the protein has been identified and it is called tropomyosin. http://www.nytimes.com/1993/12/28/health/studies-unmask-protein-culprit-behind-allergy-to-shrimp.html. ...Read moreSee 1 more doctor answer
Skin allergy: Typically skin allergy is ige mediated, you can have skin testing to determine what to avoid. There are some igg associated skin problems, and typically that requires avoidance and then challenge (elimination diet) to determine, though there are igg tests, a little more controversial than ige. ...Read more
Yes: The pollens that cause allergies are very small, and carried by the wind. Flowers need bees to cross-pollinate, because the pollen is too big and heavy to be carried by the wind. Since they're not airborne, people can't inhale them and react to them. Thus, the pollens found in bee pollen are not the pollens that cause your allergic symptoms. ...Read moreSee 1 more doctor answer
No: The sclera is not affected by allergy. The conjunctivae, the translucent tissue that covers the sclera. Is commonly affected by allergy. In food allergic patients a drop of food to which the patient is allergic dropped into the eye can cause chemosis that is marked swelling of the conjunctivitis. I've seen this when milk-allergic patients get a drop of milk in the eye. (photo of chemosis). ...Read moreSee 1 more doctor answer
