Turnbaugh was also an author on http://www.nature.com/nature/journal/v444/n7122/abs/nature05... (looking at parts of that question on mice) and also on: http://www.ncbi.nlm.nih.gov/pubmed/21543530 (looking at parts of that questions on humans).

The answer in humans does not quite match the answer in mice so far. Possible reasons to explain this discrepancy : might be the lack of a large enough group to study, or a local variation in the groups that does not generalize to mice.
