CELIAC DISEASE
If you have celiac disease and eat
foods with gluten, your immune system responds by damaging the small
intestine. Gluten is a protein in wheat, rye and barley. It is found
mainly in foods but may also be in other products like medicines,
vitamins and even the glue on stamps and envelopes.
Celiac disease affects each person differently. Symptoms may occur in
the digestive system, or in other parts of the body. One person might
have diarrhea and abdominal pain, while another person may be irritable
or depressed. Irritability is one of the most common symptoms in
children. Some people have no symptoms.
Celiac disease is genetic. Blood tests can help your doctor diagnose
the disease. Your doctor may also need to examine a small piece of
tissue from your small intestine. Treatment is a diet free of gluten.

DAIRY/CASEIN
Allergic reactions to casein and/or whey protein are caused by
an immunological sensitivity to milk protein - rather than the
sugar. A reaction to casein or whey can cause breathing problems, hives
and rashes, abdominal pain, and possibly serious weight loss. While there are at
least 30 types of potentially allergy-causing proteins in milk, casein is the
most prevalent.
The proteins lactalbumin and lactoglobulin, which comprise
the whey proteins, are also known to cause problems.
Because whey proteins are changed by high heat, those sensitive
to why can sometimes tolerate evaporated, boiled, or sterilized milk and milk
powder. That other 80% of milk, the casein, is unfortunately for sensitive
folks, heat stable. It's also the most common allergen in cheese, which
seems to be particularly craved by those who can't have it. The harder the
cheese, the more casein it contains.
And because milk proteins are not altered sufficiently when milk
is converted to other dairy products like cheese or yogurt, the only way to
avoid reactions is to avoid milk in all its forms.
Interestingly, too, the molecular structure of casein is similar
to that of gluten, and those with celiac disease may also suffer from casein
intolerance.

SOY
Soybeans have become a major part of processed food products in the
United States. Avoiding products made with soybeans can be difficult.
Soybeans alone are not a major food in the diet but, because they're in
so many products, eliminating all those foods can result in an
unbalanced diet. Consult with a dietitian to help you plan for proper
nutrition.
Symptoms of soy allergy are typically mild, although anaphylaxis is possible. Soybean allergy is one of the more common food allergies, especially among babies and children.

EGG
Egg allergy is estimated to affect approximately 1.5% of young children.
But it’s also a food allergy that is one of the most likely to be
outgrown over time.
Most allergic reactions associated with egg involve the skin, but anaphylaxis also can occur. Allergic reactions to egg are mostly IgE-mediated (involving IgE antibodies).

NUT
Peanuts are among the most common allergy-causing foods, and they
often find their way into things you wouldn't imagine. Take chili, for
example: It may be thickened with ground peanuts.
Peanuts aren't actually a true nut; they're a legume (in the same
family as peas and lentils). But the proteins in peanuts are similar in
structure to those in tree nuts. For this reason, people who are
allergic to peanuts can also be allergic to tree nuts, such as almonds,
Brazil nuts, walnuts, hazelnuts, macadamias, pistachios, pecans, and
cashews.
