Hi all! I often get questions about why Americans are developing more allergies. I am going to start periodically posting interesting articles about this subject. Here is my first post…The hygiene hypothesis is probably the leading theory. We are living in a too clean of a society. Our immune system is designed to fight microbes; however, since our exposure to microbes are decreasing, our immune system is fighting against harmless things, such as allergens. Below is an NPR story about this. I cannot believe this story is over 10 years old. It seems like yesterday when I first read this article!
