1 | 0Study Finds Probiotics 'Not As Beneficial For Gut Health As Previously Thought' (theguardian.com) null/SLASHDOT/0102641010 70\r |

5 | i An anonymous reader quotes a report from The Guardian:\r |
| 6 | i \r | |
| 7 | i > The gut microbiome is the sum total of all the\r | |
| 8 | i micro-organisms living in a person's gut, and has been shown\r | |
| 9 | i to play a huge role in human health. New research has found\r | |
| 10 | i probiotics -- usually taken as supplements or in foods such as\r | |
| 11 | i yoghurt, kimchi or kefir -- [1]can hinder a patient's gut\r | |
| 12 | i microbiome from returning to normal after a course of\r | |
| 13 | i antibiotics , and that different people respond to probiotics\r | |
| 14 | i in dramatically different ways. In the [2]first of two papers\r | |
| 15 | i published in the journal Cell, researchers performed\r | |
| 16 | i endoscopies and colonoscopies to sample and study the gut\r | |
| 17 | i microbiomes of people who took antibiotics before and after\r | |
| 18 | i probiotic consumption. Another group were given samples of\r | |
| 19 | i their own gut microbiomes collected before consuming\r | |
| 20 | i antibiotics. The researchers found the microbiomes of those\r | |
| 21 | i who had taken the probiotics had suffered a "very severe\r | |
| 22 | i disturbance." "Once the probiotics had colonized the gut, they\r | |
| 23 | i completely inhibited the return of the indigenous microbiome\r | |
| 24 | i which was disrupted during antibiotic treatment," said Eran\r | |
| 25 | i Elinav, an immunologist at the Weizmann Institute of Science\r | |
| 26 | i in Israel and lead author on the studies.\r | |

| 30 | i > The scientists also compared the gut microbiomes of the gut\r | |
| 299a08f3 NR |
31 | i intestinal tract of 25 volunteers with that of their stools.\r |
| 32 | i They found that stool bacteria only partially correlated with\r | |
| 33 | i the microbiomes functioning inside their bodies. "So the fact\r | |
| 34 | i that we all almost exclusively rely on stool in our microbiome\r | |
| 35 | i research may not be a reliable way of studying gut microbiome\r | |
| e818d449 | 36 | i health," said Elinav. In the [3]second paper , the researchers\r |
| 299a08f3 NR |
37 | i examined the colonization and impact of probiotics on 15\r |
| 38 | i people by sampling within their gastrointestinal tract. They\r | |
| 39 | i divided the individuals into two groups: one were given a\r | |
| 40 | i preparation made of 11 strains of very commonly used\r | |
| 41 | i probiotics and the other were given a placebo. Of those who\r | |
| 42 | i were given probiotics, he said, "We could group the\r | |
| 43 | i individuals into two distinct groups: one which resisted the\r | |
| 44 | i colonisation of the probiotics, and one in which the\r | |
| 45 | i probiotics colonized the gut and modified the composition of\r | |
| 46 | i the gut microbiome and the genes of the host individual."\r | |
