Interesting Studies History about Peanut Allergy
Posted: Feb 12, 2015
Peanut allergy, a type of food allergy, is considered one of the most severe food allergies due to its prevalence, persistency and potential severity of allergic reaction. According to an incomplete statistics, every one hundred Americans has two that are allergic to peanuts. Since its bad effect, scientists have done a lot of work, trying to figure this out and help those peanut-allergic people. Studies about it began at an early time, however, after reading some of them, the writer got confused and those findings are somewhat interesting.
This article mainly focused on the peanut allergy studies starting from 2010 till now. In the article that published in Nov 1, 2010, scientists said that pregnant women who eat peanuts may out infants at increased risk for peanut allergy. To some extent, they are not quite sure about this. Interestingly, after one year, in Dec., 2013, a study gave an exactly opposite suggestions. They pointed out that if the mother ate peanut and tree nut during pregnancy, the peanut and tree nut allergy incidence among their children will lower compared to those whose mother didn’t do that. Scientists in this study claimed that the evidence found in the study can’t prove a cause-and-effect relationship, but it is definite that mothers who ate peanuts during pregnancy would not cause peanut allergy in children.
Maybe, it seems that’s it. However, scientists are all keep moving and trying to find more evidence that can stand. Almost another year later, in the beginning of October, 2014, a study has revealed that skin exposure might contribute to early risk for food allergies. Scientists in this study used mice as models and they focused on how these allergy start. They exposed mice to peanut protein extract on the skin and they found that repeated topical exposure to peanut allergens would lead to a whole-body allergic reaction. Studies never ends, over 10 days later on Oct 21, a novel study has revealed more about the skin exposure. It probed into the deep of it. In the study, a strong link between early-life exposure to peanut protein in household dust and peanut allergy in children with FLG mutation.
All the way, it seems that we are at the original spot. The latest study considered peanut exposure harmful. But, maybe its still not a pure fact. More studies are needed. Maybe, that’s science and that’s biotechnology. What we need is to use it to give us a reasonable illustration.
