Peanut Allergy Up

LONDON () -- More and more children are becoming allergic to peanuts and this could be because more pregnant women are eating them, sensitizing their unborn babies, according to British doctors.

Allergy to peanuts is the most common cause of fatal allergic reaction to food. In severe cases, just a tiny amount of peanut is needed to set off a reaction.

Dr. Jonathan Hourihane and colleagues at Southampton General Hospital tested 622 adults and children with known or suspected peanut allergy. They found it is more common than believed.
