The problem with humans is that we like to take things to the extremes when we find out new information. Microbes are bad? Let's use anti-bacterial soap everywhere. Microbes are good? Let's not use soap anymore. The best advice is to live life in moderation, use some soap if you have a dirty job and don't use soap just because you're bored. Play in the sand and eat a variety of things and you'll be fine.
