Food Allergies And Intolerance Flashcards
Abnormal response to eating foods called
Adverse food reactions
Regular discomfort after eating May indicate an _ or _
Allergy
Intolerance
_ percent of adults have food allergies
2
_ percent of kids have food allergies (range)
4-8
_ more prevalent than allergies
Intolerance
Food allergy is an
Adverse immune response
There are two types of
Allergy responses
IgE-mediated allergy is when
Body creates antibodies specific to digested food
Non-IgA mediated food allergies involve
Other components of immune system
Non-IgE mediated food allergies come on more slowly and
Harder to diagnose
Non-IgA symptoms (3)
Bloating
Diarrhea
Vomiting
IgA-mediated symptoms (2)
Hives
Swelling
IgA mediated symptom _ shock
Anaphylactic
Several factors can cause food allergies, including (3)
Diet
Environment
Genetics
Dual-allergen exposure hypothesis suggests that _ can increase likelihood of allergy
Early exposure to food allergens via skin
Early exposure to food allergies via skin example
Nut oils in moisturizer
Consumption of _ in infancy could encourage intolerance
Those allergens
_ can prevent peanut allergies
Early consumption of peanuts
Children higher risk of allergies because
Compromised skin barrier
Compromised skin barrier in children with
Eczema
Whole nuts should not be consumed by children under five because of
Choking
Intolerance is a non-immune response that
Directly impacts digestion
Intolerance often relates to
Amount and frequency of food consumed
Allergy has nothing to do with
Amount/frequency of food consumed
Some intolerances triggered by
Certain chemicals in food
Food intolerances symptoms (3)
Rash
Bloating
Itching
Food intolerance symptom
Diarrhea
Many _ have lactose as fillers
Tablets
People intolerant to V
Vaso-active amines
Vaso-active amines in (R,SABC)
Red wine
Strong and blue cheese
Vaso-active amines in (T,M,PP)
Tuna
Mackerel
Pork products
People can be intolerant to natural chemicals such as (2)
Salicylate
Glutamate
People can be intolerant to some food additives such as preservatives (b)
Benzoate
People can be intolerant to some food additives such as preservatives (s)
Sulfate
People can be intolerant to some food additives such as
Monosodium glutamate
(IgE-mediated allergic reaction) when IgE first binds an allergen to a dendritic cell, it starts
A process to produce more allergen-specific IgEs
(IgE-mediated allergic reaction) IgEs then stick to _ in digestive tract
Mast cells
Mast cells are
An immune cell
IgE stick to mast cells are ready to
React to same protein when consumed again
IGE stands for
Immunoglobulin E
Inflammatory means
Histamine
Body creates IgEs specific to a (IgE-mediated allergic reaction)
Protein in the allergen food
IgE binds an allergen to a dentritic cell, (IgE-mediated allergic reaction)
Sending a message to T cells
(IgE-mediated allergic reaction) T cells are triggered to release compounds called
Interleukins
(IgE-mediated allergic reaction) interleukins cause B cells to produce more IgE that is
Specific to the allergen
Mast cell bonded to allergen causes mast cell to (IgE-mediated allergic reaction)
Release inflammatory substances
