Low Carbers please sign up to American Gut to add your data to a study about gut health.

There's a link in this article. You can read about it in here. Jeff Leach is a scientist and his interest is in the value of fibre to health. He seeks more low carb people signing up to the study on gut bacteria. The link called "American Gut" is at the bottom of the article. Pass it on if you are on other low carb forums.

http://humanfoodproject.com/americangut/ Actually here is the direct link with all the information you need about the project and you can do this is even if you are not a low carber. It sounds like an interesting project. I'd do it but from Australia its too expensive.

While I would be a great data point for their study (consuming virtually no fiber), I'm not paying to participate.
