A study was conducted at Duke University in North Carolina and the University of Arkansas for Medical Sciences. Around 15 children were given doses of peanut powder and eight children were given placebo.

At the end of the year, it was found that children given the treatment were able to bear 15 peanuts before having any allergic reaction.

"When you take the daily dose it changes your immune system in a certain way and it raises the threshold of how much food it takes to cause a reaction”, said Dr. Wesley Burks of Duke, who helped conduct the study.

In the second study conducted, twelve children were given peanut powder from age 32 months to 5 years old to know that they could eat peanuts safely after the daily treatment stopped. Around 9 out of the 12 now eat peanuts in their diets, according to the researchers.

The results are positive but more study is required before a helpful treatment can be developed.

Scientists reveal that peanut allergies are rising worldwide, but nobody has the answer for it. There is no therapy and people having peanut allergies must avoid peanuts. Around 150 people die in the US every year from food allergies.
