Peanut allergies in children have tripled over the past two decades. The cause is unknown but a new treatment is having significant success. Australian researchers have conducted a small clinical trial that has had promising results. Children were separated into two groups. All had peanut allergies. One group received a daily probiotic which contained a protein found in peanuts. The other group received a placebo. The amounts given were slowly increased for a period lasting 18 months. Afterwards, 82% of the children treated with the probiotic group were deemed tolerant to peanuts as opposed to 4% in the placebo group. In the follow up study of these children, 70% of the tolerant group were able to later consume peanuts since they had developed a long term tolerance.
