why do some people have food allergies?

Question

Answer 1

Great question!: We know that genetics play a part. Allergic parents tend to have allergic kids. Exposure to the food allergen is controversial. It appears that early exposure to foods can cause allergies to develop. How early is the question. Some recent studies even show the opposite effect. I always counsel high risk kids, to avoid highly allergenic foods early. Foods such as nuts, peanuts, shellfish.

Answer 2

Genes + Exposures: There are genetic predispositions for allergies in general, and to specific types of allergies as well (e.g. Food vs medication vs environmental allergies). However, just the genetics does not guarantee developing an allergy. There must also be an exposure in the "right" situation to trigger the allergy. The details of the "right" situation remains unclear.

Answer 3

Multiple reasons: There is still a lot of research on this topic. And multiple environmental and genetic factors. Some studies suggest that touching certain foods prior to eating them increases our sensitization. There are studies looking into whether children with eczema and atopic dermatiits are more prone to food allergy secondary to the poor skin barrier.

Answer 4

Unlikely: While one has antibodies for life after being exposed to the virus that causes mono. The virus should no longer be causing a problem.

Answer 5

Don't worry about it: Mono is caused by ebv virus, and a great many people already have the virus by the time they reach adulthood. Kids who catch ebv when young often get a milder, shorter illness (they don't remember ever having mono). There is no way to tell if one will get mono from sharing a single meal, 5 meals, or 50 meals. Ebv is generally considered a part of life. People don't spend time trying to avoid it.

Answer 6

No: A guilty conscience about food is not a healthy way to lose weight. Healthy food nourishes your body and keeps it running well. Emotional problems can sometimes confuse and complicate the process of eating, though. For instance, some with binge eating disorder suffer guilt about food. See your physician if you're concerned about your weight or your feelings about food.

Answer 7

Several: You should not have chest pain when taking a deep breath or on swallowing. You better get checked.

Answer 8

No : Allergies are not autoimmune disorder. Allergy is the overproduction of ige, the allergy antibody, to various allergens in the environment. Autoimmune disease is different antibodies to "self" antigens.

Answer 9

Allergies: Allergy is a form of an immune disorder. It is not an autoimmune disorder. . It is a form of hypersensitivity to common harmless allergens. It is mediated by ige which upon exposure to allergen activates basophils and mast cells to release inflammatory mediators such as histamine, leucotrienes and certain interleukins . These produce allergy symptoms .Commomn allergies are hives, hay fever asthm.

Answer 10

Normal!: It is not uncommon in some children. If the stool is formed , child is growing i would not worry about it. It is often from green leafy vegetables, coloring agents in the food or simply due to rapid transit from small intestine to large intestine where it normally is tuned brown.

Answer 11

Normal: The stool color is provided by the bile from the liver that is adds to fecal debris.It starts out a deep green & slowly changes thru greens to yellows to browns as the germs in the intestines metabolize the bile.Green generally means the stool in question moved through faster or was subject to less change by gut germs.
