Food allergies intestinal relationship
Food allergy is one of the world's ever increasing diseases. There are many theories about what is guilty of this steady rise: over-sterilized home environments, antibiotics and pollution are some of the most widely accepted ...
A remarkable new study * published this week by scientists at Boston Children's Hospital * says that the lack of some intestinal bacteria actually causes many food allergies. Right now, of course it's too early to say anything, but these findings can shape the future of food allergy prevention and treatment in children and adults across the globe.
How did they know it was the fault of the intestinal bacteria?
First, the team at Boston Children's Hospital collected fecal samples from 56 young patients with food allergy problems. They found that the stool of food allergy patients really carried a different bacterium.
From there, both groups removed bacteria from the feces and transferred them to mice with egg allergies. This is where the work gets interesting: The team found that mice that were given bacteria from control feces were not exposed to allergic reactions when small doses of chicken egg protein were then administered.
Although he used feces from children in this first study, research scientists hope that his findings will also apply to adults with allergies. Talal Chatila, director of the Boston Children's Food Allergy Program, said, "Remember, in adult rats with food allergies, we can suppress their disease by introducing good bacteria, which means that we are likely to treat someone with food allergies and change their immune systems."
Of course, before we get too excited, we should not ignore that these are preliminary findings that should be supported by other research. However, if their hypotheses are true, Chatila and her team may have made a tremendous breakthrough: they can treat and prevent food allergies by giving people a special mixture of bacteria.
