Poop to survive peanuts? The fecal transplants, where the fecal microbiota (stool) of a healthy donor is transferred to the digestive tract of a sick recipient, are increasingly being tested to treat intestinal disorders. The idea is simple: the "good" bacteria present in the gut of a healthy person will colonize the digestive tract of a sick person, thus balancing their microbiota and enriching it with beneficial bacteria. Since the microbiota plays an important role in digestion and immunity, this improved microbiota could normalize these processes and reduce inflammation.
What if this same principle also applied to certain food allergies? Researchers at Harvard University tested this hypothesis, with very encouraging results. Their findings were published on August 5, 2026 in Science Translational Medicine, Indeed, they show that the device can work wonders against peanut allergy.
