A food
allergy is an immune system response to a food that the body mistakenly
believes is harmful.
Although
an individual could be allergic to any food, such as fruits, vegetables and
meats, there are 9 foods that account for 90% of all food-allergic reactions.
These are: Milk, Egg,
Peanut, Tree nut (walnut, cashew, etc.), Seeds, Fish, Shellfish, Soy,
and Wheat.
MILK
ALLERGY
|
Description |
Cow’s
milk allergy is the most common food allergy in infants and young
children. It occurs more frequently in infants who are fed cow’s milk
formula than in babies who are breast-fed or who are fed hypoallergenic or a
less allergenic infant formula. Sensitivity to cow’s milk varies
greatly from person to person. Some people have a severe reaction after
exposure to a tiny amount of milk. Others have only a mild reaction
after ingesting a moderate amount of milk or dairy products. Most
children outgrow eventually outgrow cow’s milk allergy. The allergy is
most likely to persist in children who have high levels of cow’s milk
antibodies in their blood. Blood tests that measure these antibodies
can help your allergist determine whether or not your child is likely to
outgrow a milk allergy. Some people confuse milk allergy with lactose intolerance. Unlike food allergies, food intolerances do not involve the immune system. People who are lactose intolerant are missing the enzyme lactase, which breaks down lactose, a sugar found in milk and dairy products. As a result, lactose-intolerant patients are unable to digest these foods, and may experience symptoms such as nausea, cramps, gas, bloating, and diarrhea. While lactose intolerance can cause great discomfort, it is not life-threatening. |

Deli
meat slicers are frequently used for both meat and cheese products. Some
brands of canned tuna fish contain casein, a milk protein. Many
non-dairy products contain casein (a milk derivative), listed on the
ingredient labels. Some
meats may contain casein as a binder. Check all labels carefully. Many
restaurants put butter on steaks after they have been grilled to add extra
flavor. The butter is not visible after it melts. |

Milk protein is found in all dairy products,
including milk, butter, cheese, cream, custard, yogurt, ice cream, and
puddings. The following ingredients indicate the presence of milk

|
Nutrition |
Milk
is an important dietary source of protein, calcium, vitamin D and vitamin
B12. Please discuss a safe dietary alternative to cow’s milk with your
doctor or dietitian. |
EGG
ALLERGY
|
Description |
Hen’s
egg allergy is one of the most common allergies in children, second only to cow’s milk.
Most children eventually outgrow this allergy. People
who are allergic to hen’s eggs must completely avoid both the white and the
yolk. The white contains the allergenic proteins, but since it is
impossible to separate it completely from the yolk, cross-contamination is
likely to occur. Even a small amount of egg may be enough to cause an
allergic reaction. Other bird eggs also are likely to cause a reaction,
although limited research has been done on this topic. If you are on an egg-restricted diet, your intake of grain may be limited because many commercially prepared grain products, such as breads and pastas, contain eggs. A diet that is limited in eggs and grains may be low in some of the B vitamins and possibly iron. Read ingredient labels to find egg-free pastas and grain products. You can also substitute rice in some recipes that call for pasta and make your own homemade bread products. |

ingredients indicate the presence of egg protein: Egg
protein may be found in numerous products, such as baked goods, breaded
foods, cream fillings, custards, candies, canned soups, casseroles,
frostings, ice creams, lollipops, marshmallows, marzipan, pastas, salad
dressings, and meat-based dishes, such as meatballs or meatloaf. Egg whites and shells also may be used as a clarifying agent in soup stocks, consommés, wine, and alcohol-based and coffee drinks. |

Eggs
have been used to create the foam or milk topping on specialty coffee drinks
and are used in some bar drinks. Some
commercial brands of egg substitutes contain egg whites. Most
commercially processed cooked pastas (including those used in prepared foods
such as soup) contain egg or are processed on equipment shared with
egg-containing pastas. Boxed, dry pastas are usually egg-free, but may be
processed on equipment that is also used for egg-containing products. Fresh
pasta is sometimes egg-free, too. Read the label or ask about ingredients
before eating pasta. |
PEANUT
ALLERGY
|
Description |
Peanut
allergy is one of the most common food allergies. Unfortunately, it
also is one of the most dangerous, since peanuts tend to cause particularly
severe reactions (anaphylaxis). Some people are very
sensitive and have reactions from eating trace amounts of peanut.
Non-ingestion contact (touching peanuts or inhaling airborne peanut
allergens, such as dust from the shells) is less likely to trigger a severe
reaction. The
peanut (Arachis hypogaea)
is not really a nut, but a kind of legume. It is related to other beans, such
as peas, lentils, and soybeans. People with peanut allergy are not
necessarily allergic to other legumes (even soy, another
of the “big eight” food allergens), so be sure to speak with your doctor
before assuming that you have to avoid these protein-rich foods. A person
with a peanut allergy may also be allergic to tree nuts (almonds, walnuts,
hazelnuts, cashews, etc.). In fact, some 30-40% of people who have
peanut allergy also are allergic to tree nuts. Not surprisingly, allergists
usually tell their peanut-allergic patients to avoid tree nuts. Researchers have isolated three major peanut allergens. They are trying to learn why peanuts cause such severe reactions and why the number of people who suffer from peanut allergy is increasing. Investigators also are trying to develop therapies that would prevent anaphylaxis in people with peanut allergies. |

TREE
NUT ALLERGY
|
Description |
Tree
nut allergy is one of the most common food allergies in children and
adults. Like peanuts, tree nuts (almonds, cashews, walnuts, etc.) tend
to cause particularly severe reactions, even if a person is exposed to only a
tiny amount. In
a registry of 5,149 people who had peanut
or tree nut allergy, the median age of reaction to tree nuts was 36
months. Sixty-eight percent of the tree nut-allergic participants were
not aware of any previous exposure to tree nuts before their first
reaction. This allergy tends to be life-long; recent studies have shown
that approximately 9% of tree nut-allergic children eventually outgrow their
allergy. People seldom are allergic to just one type of tree nut, so allergists usually will tell patients to avoid all tree nuts. |
|
Hidden Sources |
Artificial
nuts can be peanuts that have been deflavoured and reflavoured with a nut, such as pecan or walnut. Mandelonas are peanuts soaked in almond flavoring. Mortadella may contain
pistachios. Tree
nuts have been used in many foods, including barbecue sauce, cereals,
crackers, and ice cream. Kick sacks, or hacky sacks, bean bags, and draftdodgers are sometimes filled with crushed nut shells. |

The
following common nuts are considered tree nuts under U.S. law: almond;
Brazil nut; cashew; chestnut; filbert/hazelnut; macadamia nut; pecan; pine
nut (pignolia nut); pistachio; walnut. The
following are uncommon, additional tree nuts that require disclosure by U.S.
law. However, the risk of an allergic reaction to these nuts is
unknown:
beechnut; ginkgo; shea nut; butternut; hickory;
chinquapin; lychee nut; coconut; pili nut.

SEED
ALLERGY
|
Description |
Sesame seed allergy appears to be on
the rise in many countries, including the United States. These seeds
are capable of causing severe allergic reactions. Canada and the
European Commission have added sesame to the list of ingredients that must be
reported on food labels, although the U.S. has not yet done so. The more widely an allergenic food is
consumed in a particular country, the more likely the population is to report
an allergy to that food. In the Middle East, where sesame seeds and oil are
dietary staples, the incidence of sesame seed allergy is very high. In
fact, sesame is the third most common allergy in Israeli children, after cow’s milk
allergy and egg
allergy. Researchers theorize that the
growing popularity of snacks and ethnic foods that contain sesame in Europe,
North America, Australia, and New Zealand accounts for the increase in sesame
seed allergy in these parts of the world. Allergies to other seeds (e.g., poppy, sunflower, pumpkin,
rapeseed, and flaxseed, also known as linseed) are much less common, so they
are not discussed in detail here. People who are allergic to one type
of seed don’t necessarily have to avoid all others, so you should discuss
this matter with your doctor. |

The
following ingredients and foods indicate the presence of sesame seed protein:
Non-food
sources of sesame seeds include health and beauty aids (cosmetics, soaps,
hair care products, etc.), certain drugs and ointments, pet food, and
livestock feed. |
SHELLFISH
ALLERGY
|
Description |
Allergic
reactions to fish and shellfish are commonly reported in both adults and
children. It is generally recommended that individuals
who have had an allergic reaction to one species of fish, or positive skin
tests to fish, avoid all fish. The same rule applies to shellfish. If you
have a fish allergy but would like to have fish in your diet, speak with your
allergist about the possibility of being tested with various types of fish. Shellfish
allergy usually develops in young adults. In fact, it is the most
common significant food allergy reported by adults and is considered
life-long. Along with peanuts and tree
nuts, shellfish are the most frequent triggers of anaphylactic
reactions. There
are two kinds of shellfish: crustacea (such as
shrimp, crab, and lobster) and mollusks (such as clams, mussels, oysters, and
scallops). Reactions to crustacean shellfish tend to be particularly
severe. If you are allergic to one group of shellfish, you might be
able to eat some varieties from the other group. Since most people who
are allergic to one kind of shellfish usually are allergic to other types,
however, allergists usually advise their patients to avoid all varieties.
If you have been diagnosed with a shellfish allergy, never eat any kind
of shellfish without consulting your doctor first. When
eating out, people with shellfish allergies should be particularly alert to
cross-contamination. Always check with the chef to make sure that
shellfish are not cooked on the same skillet or in the same oil as other
food. You also should make sure that your dishes are not prepared with
the same utensils or on the same work surfaces as shellfish.

FISH
ALLERGY
|
Description |
Finned
fish can cause severe allergic reactions. This allergy is usually
life-long. The protein in the flesh of fish most commonly causes the
allergic reaction; however, it is also possible to have a reaction to fish
gelatin, made from the skin and bones of fish. Although fish oil does
not contain protein from the fish from which it was extracted, it is likely
to be contaminated with small molecules of protein and therefore should be
avoided. More
than half of all people who are allergic to one type of fish also are
allergic to other fish, so allergists often advise their patients to avoid
all fish. However, many people with fish allergies are able to eat
canned tuna or salmon, which are less allergenic than fresh fish. Finned fish
and shellfish
do not come from related families of foods, so being allergic to one does not
mean that you will not be able to tolerate the other. Be sure to talk
to your doctor about which kinds of fish you can eat and which to avoid. When
eating out, people with fish allergies should be particularly alert to
cross-contamination. Always check with the chef to make sure that the
fish is not cooked on the same skillet or in the same oil as other
food. You also should make sure that your dishes are not prepared with
the same utensils or on the same work surfaces as fish. |

perch; pike; pollock; salmon; scrod; sole; snapper;
swordfish; tilapia; trout; and tuna.

SOY
ALLERGY
|
Description |
Like
peanuts, soybeans are legumes. In fact, soy and peanut proteins are
similar in structure. Nevertheless, a person who is allergic to soy
won’t necessarily be allergic to peanuts, and vice versa. Soy is widely used
in many food products, so if you have a soy allergy, it is especially
important to read ingredient labels with care. Comparatively
little research has been done on soy allergy, but studies indicate that it
generally occurs early in childhood and often is outgrown by age three. 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. |

WHEAT
ALLERGY
|
Description |
Wheat
allergy most commonly affects children and often is outgrown by age
three. Wheat, a type of grain, contains four major proteins that can
cause an allergy: albumin, globulin, gliadin, and
gluten. Gluten is also found in barley, rye, and oats. You or
your child may not necessarily have to avoid foods that contain grains other
than wheat. However, about 20% of wheat-allergic children also are
allergic to other grains. Be sure to ask your doctor whether foods
containing barley, rye, or oats are safe for you or your child to eat. A
wheat allergy should not be confused with “gluten intolerance” or celiac
disease. Celiac
disease (also known as celiac sprue), which
affects the small intestine, is caused by an abnormal immune reaction to
gluten. Usually diagnosed by a gastroenterologist, it is a digestive disease
that can cause serious complications, including malnutrition and intestinal
damage, if left untreated. |
