Food Allergies... What you should know
You've met someone, know someone, or you may be someone yourself... who has a particular food allergy. Today, food allergies are becoming more and more common. Why is this? The number of people who have a food allergy is growing at a very concerning rate. In fact, about 2 percent of adults and 6 percent of children have a true food allergy. And far more have food intolerances, unpleasant symptoms triggered by food.
In a true food allergy, your immune system mistakenly identifies a specific food or a component of food as a harmful substance. Your immune system then triggers certain cells to produce immunoglobulin E (IgE) antibodies to fight the culprit food or food component (the allergen). The next time you eat even the smallest amount of that food, the IgE antibodies sense it, and signal your immune system to release histamine and other chemicals into your bloodstream.
These chemicals cause a range of allergic signs and symptoms. Histamine is partly responsible for most allergic responses, including dripping nose, itchy eyes, dry throat, rashes and hives, nausea, diarrhea, labored breathing and even anaphylactic shock.
The great majority of life threatening food allergies are triggered by certain proteins in:
Shellfish, such as shrimp, lobster and crab
Tree nuts, such as walnuts and pecans
Food allergies are also commonly triggered by proteins in these foods:
Food intolerance and other conditions: Not food allergies
Other reactions to food don't involve your immune system or the release of histamine, as these reactions aren't true food allergies. Instead, they may be a food intolerance. Because a food intolerance may involve some of the same signs and symptoms as a food allergy does - such as nausea, vomiting, cramping and diarrhea - people often confuse the two.
If you have a food intolerance, you may be able to eat small amounts of problem foods without a reaction. By contrast, if you have a true food allergy, even a tiny amount of food may trigger an allergic reaction.
One of the tricky aspects of diagnosing food intolerance is that some people are sensitive not to the food itself but to a substance or ingredient used in the preparation of the food. For example, sulfite preservatives can trigger asthma signs and symptoms in sensitive people.
Below is a listing of the "Great 8". The 8 Food Allergies, what they're found in, what they can be hiding in, and substitutions you might want to try. In each allergy category is also a helpful website that can further go into detail about that particular allergy and is a great resource.

Sauces used in ethnic meals (Asian, African and Mexican), candy, chocolate, sunflower seeds and nut butters (which often are processed on shared equipment -- read labels to find ones that keep peanuts separate), some natural and artificial flavors and many other foods (i.e., read labels of all processed foods).
Peanut allergies are serious business! Many schools are adopting a "peanut-free environment" program... airlines don't serve peanuts anymore either. Careful with these.
Dip apples in a little honey instead of peanut butter, or pop some popcorn when you're craving a crunchy, salty snack.
