Intestinal bacteria have attracted recent attention since they were discovered to influence various physiological functions and diseases in humans. Researchers from Kumamoto University in Japan analyzing the influence of changes in intestinal bacteria on sugar and lipid metabolism have found that secondary bile acids produced by the bacteria can influence blood glucose and lipid concentrations as well as parts of their molecular mechanisms...

A large-scale study into the effect of food and medicine on the bacterial diversity in the human gut was led by RUG/UMCG geneticist Cisca Wijmenga. Researchers collected stool samples from more than 1100 people taking part in the LifeLines programme, which is monitoring the health of 165,000 residents of the Northern Netherlands. The samples were used to analyze the DNA of the bacteria and other organisms that live in the gut. In addition to stools, the study collected information on the participants’ diet, medicine-use and health.

This study is unique in that it focused on a group of normal people whereas previous research was frequently focused on patients wi...
