Flour relieves kids’ peanut allergies in study

– An experimental therapy that fed children with peanut allergies small amounts of peanut flour has helped more than 80 percent of them safely eat a handful of the previously worrisome nuts.

Although experts say the results of the carefully monitored study are encouraging, they warn it isn’t something that parents should try at home.

Peanut allergies are on the rise globally and affect about 1 in 50 children, mostly in high-income countries. The consequences can be life-threatening – peanuts are the most common cause of fatal food allergy reactions. There is no way to avoid a reaction other than just avoiding peanuts. Allergy shots used for environmental triggers like pollen are too risky.

Doctors at Addenbrooke’s Hospital in Cambridge started by giving 99 children ages 7 to 16 with severe peanut allergies a tiny 2-milligram dose of a special peanut flour mixed into their food. Slowly they increased that amount to 800 milligrams. The dose increases were given at a facility where the children were observed for dangerous side effects – the most frequent were itchiness in the mouth, stomach pains or nausea.

After six months of treatment, more than 80 percent of the children can now safely eat five peanuts at a time.

“This made a dramatic difference to their lives,” said Dr. Andrew Clark, of the University of Cambridge in Britain, who led the research. “Before the study, they could not even tolerate tiny bits of peanuts and their parents had to read food labels continuously.”

The intention of the treatment isn’t to help kids eat large amounts of peanuts, but to prevent a life-threatening allergic reaction in case they mistakenly eat trace amounts.
