In reality, our modern, sanitized lifestyle has wiped out a lot of beneficial microbes in our gut that help us stay healthy. Being exposed to certain microbes in the womb and early childhood can actually strengthen our immune systems and protect us from illnesses later on. When the immune system is not challenged enough, it might start looking for stuff to do, like overreacting to things that are not really dangerous, like pollen and peanuts. This is believed to cause allergies, asthma, eczema, childhood diabetes, and inflammation later in life.
