Oversensitive immune systems in children may be contributing to a rise in food allergies.
The number of patients who present at hospital casualty departments with severe food allergies has risen to 30,000 per year, reports MSNBC News. About half of these cases derive from peanut allergies. Some 200 people die following food allergy crises every year.
Ironically, improved health care and more effective vaccines may be part of the problem. Little children are not falling ill so often, and thus their immune systems are prone to overreact to sensitivity to food types.
On a brighter note, most victims of severe food allergies are children, 20% of whom go on to outgrow the allergy.
