What you don’t know about food allergies

The prevalence of severe food allergies ranges from 10% for children aged 2 years, 7.1% for children aged 14 to 17 years, and 10.8% for adults aged 18 years and older. Infants and toddlers with milk, eggs, wheat and soy are often allergic to milk, but other Big 9 allergies are almost always lifelong. And those who were not allergic as young people are not always so. New food allergies can develop at any age.

According to Dr. Scott H. Schikeller, an allergist at Mount Sinai School of Medicine in New York, and co-author, “Surprisingly, about half of adults with food allergies in the United States develop at least one food allergy in adulthood. The largest number of such cases is caused by shell allergies. “

The only real food allergy is a harmful immune response, Dr. Sicherer explained. The body responds to otherwise innocent food and launches a full-blown attack, as if it were a life-threatening infection. Symptoms include hives, dyspnea, vomiting, and anaphylaxis. This is a severe, fatal shock response that occurs within seconds or minutes of exposure to the allergen, and in some cases in very small amounts. As a result, most airlines no longer offer peanuts for leaflets. Simply dusting with peanuts can be fatal to people with peanut allergies.

Over 40% of children with food allergies and half of adults with food allergies experience at least one serious reaction in the course of their lives. Among those who are allergic to one or more of the Big 9 allergens, the severe response rate is over 27%, with peanut allergies leading the list at 59.2% in children and 67.8% in adults with peanut allergies.

Still, many who think they have food allergies do so when tested in a blind oral challenge to test food under medical supervision to see if their child responds. Not. Gold standard for diagnosing food allergies.. Others mistakenly think of all kinds of side effects on food as allergies, from stomach upsets to headaches. For example, food intolerance to lactose, the natural sugar in milk, is due to a deficiency of the enzyme lactase rather than an immune response. Many Asians lack the enzymes that digest alcohol, which causes redness and flushing when alcohol is consumed. Others may think they are allergic because they are experiencing druglikeness, such as the extreme jitter caused by caffeine in coffee and tea.

From time to time, long-term avoidance of food can cause an allergic reaction when the food is finally consumed. This can occur in children with skin allergies who avoid milk.They may eventually experience an allergic reaction when consuming it.. Occupational exposure, use of skin care products, and even tick bites can cause adult-onset food allergies if both are cross-reactive with allergenic substances.

And for the past few years, allergic families have been advised not to expose their children to peanuts until the age of three (advice that likely contributed to the current explosion of peanut allergies in children), but now. Seems to have been introduced early in 6 months — highly allergenic foods are actually protective and reduce the risk of later reactions, Dr. Sikeller said...
