Even though several people enjoy food products made from peanuts, some especially small kids are developing severe allergic reactions towards peanuts. So much exposure to such food products may cause lethal anaphylactic shock, particularly to those who have peanut allergy. For such people, a serious reaction can be caused by just breathing dust from peanuts or taking a single peanut. Allergic reactions also have been caused by eating food products processed by machines which have formerly processed peanuts and this makes avoiding such foodstuffs difficult. In this case, the rate of school-age children with peanut allergy has lately doubled. Yet scientists have not established what actually makes peanuts such a danger or why there has been so much prevalence of allergy. However, theories abound that mostly entail an overactive body immune system.

Research has revealed that parents nowadays feed their children with more handy foodstuffs where most of which have peanuts or else their derivatives. By doing so, they bombard immune system of their kids with these allergens hence attacking them instead. This has eventually caused foods allergy to be on rise. Peanuts appear to cause fierce immune reactions to small children and this may be because these legumes contain a number of proteins that are not present in most of other foodstuffs. The structure of such proteins kindles a well-built immune response. Additionally, early and much disclosure to peanut foodstuffs can cause immune system to misidentify such foods as unsafe. This is because most of the allergic children develop complication the first time they take peanuts. On the other hand, roasting peanuts as most Americans is said to alter the shape of proteins causing them to be a bigger target. Likewise, most children are spending less time outside and tend to lack vitamin D, thus their body may mislabel proteins from peanuts as dangerous.
