Dr. Walt Larimore is a long time friend, family medicine doc, author, speaker, professor, and just a great guy. His blog always has some interesting stuff on it. This week he writes about a study where kids whose parents wash dishes by hand have fewer allergies than the dishwasher machine folks!  Probably sterilizes the bugs less. Also they found that kids that eat fermented stuff also do better. The evidence just keeps accumulating that our bodies develop a better immune system if we get challenged periodically through life rather than trying to keep everything squeaky clean. It’s sometimes called “The Hygiene Hypothesis.”  As PaleoPathologistMate says, “A kid’s gotta eat some dirt.”
