Daily peanut exposure can desensitise allergic adults, study suggests

The Grown Up Peanut Immunotherapy (GUPI) trial recruited 21 adults aged between 18 and 40 with a clinical diagnosis of peanut allergy.

Participants were given steadily increasing doses of peanut flour over a period of months .

Two-thirds of the trial participants were able to eat the equivalent of five peanuts without reacting.

The findings suggest the window of opportunity for treating allergies could extend into adulthood.
