answer:The exact cause is unknown, but many theories say that it is caused by the consumption of peanuts during pregnancy or breastfeeding. Once, I heard that the rising consumption of boiled / salted peanuts was what caused the rise of peanut allergies. There is also the theory that exposure to soy milk could cause it. For each of these studies, however, there is another study that found no such link. Another thing is that the perceived amount of allergies has been inflated by disproportionate media coverage. According to Wikipedia, about 150 children die from food allergies every year. 10,000 children are hospitalized for brain injuries from sports. 2,000 children drown. 1,300 children die from guns.
