African ancestry more prone to peanut allergy, reveals report.
Rajesh Kumar at the Children's Memorial Hospital in Chicago and his team looked at over 1,000 children to find out if race and ancestry played an important role in food allergies.
The group, after screening the collected genomes, also searched antibodies to peanuts in the children's blood.
Reports showed that the high levels of antibodies suggested the immune system overreacted to peanuts earlier.
"For every 10 percent increase in African ancestry... there was a 25 percent increased risk of having peanut antibodies at levels associated with allergy," New Scientist quoted Kumar as saying.
The finding appears in the journal Pediatrics.
