Allergies to peanuts and other foods are showing up in children at younger ages, and parents should postpone exposing susceptible children to peanuts.
In a study of 140 children with peanut allergies, the median age of the first allergic reaction was 14 months among those born between 2000
and 2005, compared with 22 to 24 months among allergic children born between 1988 and 1999.
"There's a valid reason to delay introduction to products containing peanuts," said Dr Todd Green of the Children's Hospital of Pittsburgh. "When kids are older, it can be easier to manage bad reactions. They can tell you right away if their mouths feel funny. For that reason alone, it's worth delaying exposing your child to a peanut product."
The American Academy of Paediatrics recommends that children with a family history of allergies avoid peanuts until age 3.
"More research needs to be done to determine why peanut allergy in children is increasing and, most importantly, how to stop this increase," said Anne Munoz-Furlong, director of the Food Allergy and Anaphylaxis Network in Fairfax, Virginia.
Among 12 million Americans estimated to have food allergies, nearly 2 million are allergic to peanuts, although up to 20 per cent outgrow it, researchers say. Many patients in the study were also found to be allergic to other foods, commonly eggs, soy, wheat, tree nuts, and shellfish.
As many as one-third of people with peanut allergies have severe reactions such as trouble breathing, a drop in blood pressure and gastro-intestinal problems.
About 200 US deaths occur each year due to food-related allergic reactions, usually involving peanuts or tree nuts, said another of the study's authors, Dr Wesley Burks, of Duke University.
Usually, an allergic reaction will occur within seconds of ingestion in the form of an itchy rash, or swelling of the skin, followed by respiratory symptoms and vomiting.
Said Dr Burks: "The take-home message here is that families in that at-risk group have an antihistamine available and then not stay home - get medical assistance."
