BLOG 280 FOOD ALLERGIES
Some foods can trigger uncomfortable and health risk immune
responses for people who consume them. Lately, we hear about peanuts and dairy
being common foods people are allergic to. According to the Food Allergy
Research and Education (FARE), 33 million people have food allergies and 1 in
13 children have them too. The FDA has concluded that there are specifically 9
foods that are responsible for 90% of these food allergies.
When the immune system reacts to a food it does not like, it
is on the defense against a food protein the system feels threatened by. The
immune system will then create antibodies to put up a fight. Food allergies
come in 2 types. Immunoglobulin E (IgE) mediated are the most common type. When
unwanted food enters, gE antibodies release chemicals to put up a fight. For
example, histamine can be released which can cause anaphylaxis. The other type
of food allergy is called Non-IgE mediated. Something like heartburn or eczema
might happen as an immune response.
Some signs of an allergic reaction to a food could be
dizziness, hives, stomach pain, vomiting, difficulty breathing, diarrhea, low
blood pressure, and/or feeling faint. The most severe reaction is anaphylaxis. Symptoms
of anaphylaxis can include difficulty swallowing, lips, tongue, and/or skin
becoming blue or swollen (such as the throat), very fast breathing, sudden
rash, and/or fainting/unconsciousness.
The 9 most common foods people are allergic to are the
following:
1.
Shellfish – The body does not like the proteins called
tropomyosin, arginine kinase, and parvalbumin that are found in the crustacean
and mollusk types of fish. Examples of shellfish include shrimp, scallops,
squid, lobster, prawns, and crayfish.
2.
Fish – This is different from shellfish because
the proteins are not the same. About 40% of people allergic to fish don’t
present this effect until adulthood.
3.
Wheat – This allergy is more common in children,
but most do outgrow is by the age of 10. The body doesn’t like one of the many
types of proteins in wheat. Gluten is the most common protein people are
allergic to which is associated with celiac disease.
4.
Soy – This is from the protein in soybeans. Soy
milk and soy sauce are common culprits.
5.
Sesame – in 2023, all foods that have any type
of sesame must be labeled. Many Asian food and sauces have sesame.
6.
Peanuts – In the U.S., 6.1 million people are allergic to peanuts. For people
under age 18, it is the most common allergy. About 20% of children outgrow the
allergy by their teenage years.
7.
Tree nuts – There are several types of tree nuts,
and it is recommended that if you are allergic to one, you shouldn’t have any
of them at all. Examples of tree nuts include cashews, walnuts, macadamia nuts,
pistachios, Brazil nuts, almonds, walnuts, and pine nuts. Many oils and butters
have these. Generally, tree nut allergies are lifelong.
8.
Eggs – For children, eggs are the second most
common type of allergy. About 68% fo children do outgrow this by age 10. Some
people can be allergic to just the yoke or just the egg white. More people are
allergic to the egg white part. Some people don’t have problems with eggs if
they are baked goods or other recipes possibly because the heat preparation has
altered the allergen.
9.
Cow’s milk – About 2-3% of toddlers are allergic
to cow’s milk and about 90% of them will outgrow this be age 3. Many foods must
be avoided like ice cream, yogurt, cream, margarine, butter, and cheese.
Although these 9 are the most common, there are reported 170
types of foods people can be allergic to. Blood tests, skin prick test, elimination
diet, and the patch test, are examples of diagnosis. Eating whole food and
preparing your own food helps you to know what exactly you are eating. Be in
control of your ingredients. Unfortunately, food allergies are usually
discovered after this fact, so some reaction occurred. Being aware of what
other family members have been allergic to could be a proactive measure, but
there is no guarantee. Some diets just can’t have some food, so the restriction
just comes forced.
