Why are food allergies so common now when they seemed to be rare or non-existent before?
In: Biology
Food allergies numbers are much higher in the developed world than developing. The reasons aren’t 100 percent understood yet. The basic idea being we are too clean. As children are immune systems developed by being exposed to all kinds of things. But now we deny that by overly processed foods that, aside from what you usually read as a negative, have preseritivies that prevent molds and bacteria growth that our bodies need to fight to become stronger. That is just a simplification. A more specific, huge offender, peanuts contain a protein that our body will think is bad and kick off an immune response. For the past several years mothers were advised to keep peanuts away from infants to keep them safe. The have been rethinking that as it’s being realized that the early exposure is what made the child’s body not fight them.
