Fecal transplants - dubbed “poop pills” - from people without food allergies have proven to help people with peanut allergies tolerate the nuts months later, a small but groundbreaking new clinical trial of 15 adults shows. The findings could help the 33 million Americans who have at least one food allergy, as well as the nearly five million Americans who suffer from peanut allergies. Peanut, nut, milk and egg allergies are some of the most hazardous food allergies, according to the American Academy of Allergy Asthma and Immunology. Because the mouse studies tested a different allergen, the transplant is likely to work for more than just peanut allergies, study co-author Talal Chatila, an immunologist at Harvard Medical School, told Nature.
