The gut reflects what we eat

Interactions between our gut microbiota, diet and weight are more intimate than previously assumed. Peter Turnbaugh and his colleagues made some surprising discoveries in their experiments with 'humanized' mice.

If you switch from a healthy, low-fat diet to a high-fat 'Western' diet, your gut microbiota may change within a day. These changes are also reflected in the gene expression of the gut bacteria, as well as in their metabolic functioning. That is the conclusion of a recent article in Science Translational Medicine (11 November 2009) by Peter Turnbaugh, Jeffrey Gordon and colleagues. Turnbaugh, a microbiologist now at Harvard University, was one of the keynote speakers at the Gut Day 2009, held last November in The Netherlands.
