"We have someone with a severe peanut allergy on board, so peanut-containing snacks will not be served," the flight attendant announced.
"Please refrain from eating any of your own snack foods with peanuts as an ingredient for the duration of the trip," he continued.
I had packs of peanut butter crackers and peanuts in my purse waiting to be eaten. I did not have a chance to eat during my layover, so I was looking forward to a snack.
However, despite being a little hungry, I wasn't about to put anyone's life at risk for the sake of a few peanuts.
In fact, the flight was so turbulent that no snacks or beverages of any kind were served. The beverage cart was kept parked, and I watched a movie to keep my mind off of eating, drinking and the fact that I felt like I was on a roller coaster.
I enjoy peanuts in other situations. When I need a quick snack, I grab a few peanuts to tide me over.
Peanuts are an excellent source of protein and fiber, which help you feel full. They contain monounsaturated and polyunsaturated fats, which are heart healthy.
However, peanuts are among the foods most associated with allergic reactions, and the symptoms can range from mild to severe. Typically, some of the proteins naturally found in peanuts (arachin"and conarachin) are associated with their potential for allergic responses.
When a person with a food allergy is exposed to the allergen, the immune system takes action.
Peanuts are among the eight major food allergens. The remaining seven allergens are milk, eggs, tree nuts, wheat, soy, fish and shellfish.
For someone allergic to peanuts, mild symptoms may include hives, rash, itchy mouth, nausea, stomach pain, nasal congestion, sneezing and many others.
A severe allergy to peanuts may include swelling of the lips, tongue or throat; trouble swallowing; shortness of breath; feeling faint; loss of consciousness; chest pain; and/or weak pulse.
The worst-case scenario is anaphylaxis, when the allergy affects many areas of the body. The person may have tightened airways, a swollen throat, a severe drop in blood pressure, rapid pulse and/or loss of consciousness. Without prompt medical treatment, such as an injection of epinephrine, a peanut allergy can be fatal.
Even tiny amounts of the allergen through breathing or skin contact can lead to reactions.
According to the Food Allergy Research and Education (FARE) organization, 32 million people in the U.S. have food allergies. About one in 13 children (about two in every classroom) has some type of allergy.
Further, the FARE organization noted that childhood hospitalizations related to food allergy tripled from the late 1990s to the mid-2000s.
Those with a peanut allergy need to completely avoid peanuts or foods that may have come into contact with peanuts during the manufacture of foods. Just like cross-contamination in foods, some amounts of peanuts can be transferred from one food to another through contact with utensils, plates and other surfaces.
The federal Food Labeling Act requires that all packaged food products sold in the U.S. that contain peanuts must list the word "peanut" on the label. Look at the ingredient statement for the allergen statement, "Contains peanuts."
Other foods, such as beer nuts, mixed nuts, peanut oil, nut meats, mandelonas and several other ingredients, need to be avoided by those with peanut allergies. Mandelonas are peanuts soaked in almond flavoring, by the way.
Although reading food labels is a good idea any time, reading is especially important if you have a food allergy. Remember, too, that ingredients in packaged food products may change without warning, so check ingredient statements every time you shop. If you have questions, call the manufacturer.
