Food allergies - PAEG inglés CLM

Are you hungry? Perhaps you would like a peanut butter sandwich and some milk. For some people – including two million US teenagers – such foods could cause a severe adverse reaction, or even death.
Potentially life-threatening allergies to food are common among children and are often outgrown over time, although allergies to peanuts or other nuts almost never disappear. Sometimes, an allergic person may suffer a reaction from simply touching or smelling the dangerous food.
An allergic reaction is a mistake made by the body. It may identify certain foods as harmful and try to attack the “threat” by releasing chemicals such as histamine, which cause an allergic reaction. The reaction may prove fatal if the vocal chords swell shut, leading to suffocation. Or the sufferer may experience an anaphylactic reaction, which results in a decrease in the flow of blood to the heart, lungs or brain, leading to seizures and, possibly, to death.
Allergic individuals are encouraged to wear medical alert bracelets, and carry anti-histamine for immediate injection if necessary. But recent research shows that teenagers often ignore these precautions partly because they want to conform and partly because they tend to minimise the risks. Certainly, living with a potentially fatal food allergy can be difficult for teenagers. They have to cope with telling new acquaintances about their allergy, eating carefully in restaurants, and reading labels on food packaging. And, since even kissing someone who has recently eaten a forbidden food can trigger a reaction, they may even have to ask their dates to brush their teeth before kissing!
So the next time you reach for some peanuts, remember those who can’t. Some people avoid peanuts because they are fattening or can cause skin problems, but for a small minority, those peanuts are a killer.
