Australian researchers have found that eating a daily dose of Lactobacillus, a type of bacteria found in some fermented foods, can help overcome potentially fatal peanut allergies, CNBC reported Thursday, citing a study published in The Journal of Allergy and Clinical Immunology. The scientists combined the bacteria with a current technique called oral immunization therapy, in which people with peanut allergies take small amounts of peanut in their diet in an attempt to build up an immunity. In a study involving 28 children over an 18-month period, more than 80% of those receiving the Lactobacillus in addition to small amounts of peanut flour "were able to tolerate peanuts well at the end of the trial, compared with less than 4% of the control group" who received only the flour, the report said. Peanut allergies can trigger anaphylaxis, a tightening of the muscles which can restrict breathing and sometimes cause death. marketwatch
