Researchers have found a way to treat peanut allergies — feed people small amounts of peanuts, increasing the amount daily:
The new treatment uses doses of peanuts that start as small as one-thousandth of a peanut and eventually increase to about 15 peanuts a day. In a pilot study at Duke University and Arkansas Children’s Hospital in Little Rock, 33 children with documented peanut allergy have received the daily therapy, which is given as a powder sprinkled on food. Most of the children are tolerating the therapy without developing allergic reactions, and five stopped the treatment after two and a half years because they could now tolerate peanuts in their regular diet. But four children dropped out because they could not tolerate the treatment.
In a related study of just 18 children, the researchers gave the treatment to 12 children and a placebo powder to 6. After 10 months, the children were given a medically supervised test exposing them to peanuts. In the placebo group, the children developed symptoms after ingesting the equivalent of one and a half peanuts. In the treatment group, the children tolerated 15 peanuts without symptoms.
