Prof. Higa, de uitvinder van EM Effectieve Micro-organismen, zegt het al 20 jaar. De EM micro-organismen hebben een enorm effect omdat zij andere micro-organismen meekrijgen in hun manier van functioneren (fermenteren in plaats van afbreken/bederven). Zo kunnen 5% goede EM bacteriën 90% ‘meelopers’ mobiliseren.
Onderzoekers uit Engeland en Zwitserland hebben nu hetzelfde ontdekt: “darmbacteriën praten met elkaar. Probiotica bacteriën hebben een enorm effect op wat ander bacteriën doen.”

Mmmm … Bacteria

When you eat a cup of yogurt, billions of bacteria make their way to your gut. Some researchers believe that these “probiotics” can be good for you, alleviating everything from bowel disease to allergies. Now, a team of researchers has shown that, at least in mice, supplementing food with a helping of “good” bacteria can cause profound metabolic changes, including some that may be linked to weight loss.
The human gut hosts 1000 species of microorganisms–more than a kilogram of cells in all. Recent studies indicate that this thriving ecosystem plays an important role in human health and may even contribute to obesity (ScienceNOW, 20 December 2006). Last year, Jeremy Nicholson, a biochemist at Imperial College London, and a team of researchers from Imperial College and the Nestlé Research Center in Lausanne, Switzerland, showed that replacing mouse gut microbes with human microbes caused widespread metabolic changes in the mice (ScienceNOW, 23 May 2007). Nevertheless, scientists remained sceptical that probiotics could have a similar effect, because probiotic foods add only a few billion foreign microbes to a native population of tens of trillions.
In the new study, Nicholson’s group returned to the mice harbouring human gut microbes. The researchers supplemented the animals’ diets with a solution containing one of two species of Lactobacillus bacteria, which are present in yogurt and baby formula. Control mice were given saline solution as a supplement.
After 2 weeks, the team measured the metabolic profiles of the mice, analyzing faeces, urine, plasma, intestinal contents, and liver tissue. The results, published in the 15 January issue of Molecular Systems Biology, show that although the composition of gut microbes changed only slightly in the three groups of mice, the animals’ metabolic profiles–including various markers for blood cholesterol and amino acid levels in the liver–were profoundly different.
Of particular note, says Nicholson, was the effect of probiotics on bile acids, which help the small intestine absorb fat. Probiotics diminished the function of the acids, Nicholson notes, which may make it harder for the animals to absorb fat–and thus should keep them slim. As for how a relatively small number of foreign microbes could have such a dramatic effect, Nicholson believes it results from communication with the native bugs. “Gut bacteria talk to each other,” he says, so despite their relatively modest numbers, “probiotics have a huge effect on what those other bugs do.”
Although he cautions that the gut is simpler in the experimental mice than in humans, Glenn Gibson, a microbiologist at Reading University in the U.K., calls the work “very thorough” and says that it foretells an exciting and potentially revolutionary future in which microbial interventions can correct metabolic abnormalities. “We can’t change human genetics,” he notes, “but if we can alter metabolism with minor changes in gut bacteria, that’s very exciting.”

Eat Good Bacteria. Might be the take away message of a recent study published in the journal of Molecular Systems Biology. The scientific team, including Jeremy Nicholson a biochemist at Imperial College London, found that even a small amount of ‘good’ bacteria introduced to the digestive track of a mouse can create profound changes in the mouse’s metabolism. In what has been a controversial issue, the solid study points to the increasing evidence that living healthy, reducing disease, and fighting obesity, at least in part, might be helped if we all ate a few more ‘good’ bacteria.
The digestive track is a mysterious, and crowded place. More than 1000 different species totalling over 100 trillion individual microorganisms call your gut home. As Stephen Colbert points out you have more nerve endings in your gut than you have in your head. What are all those nerve endings doing? Well, they might be listening to the conversation.
“Gut bacteria talk to each other,” says Nicholson. The bacteria in your gut perform incredibly useful work in digesting food, yet they must all work in some coordinated fashion to get the job done. Achieving the right mix of bacteria, can lead to the right signals or ‘talk’, which can be critical to the digestive system, and metabolism. The kicker is you don’t even need that many ‘good’ bacteria to make a difference.
Nicholson points out that one major finding of their study is that a relatively small number of ‘good’ bacteria (sometimes called probiotics) can have a huge effect on what the rest of the gut community decides to do. Just a few billion probiotics, like those found in a serving of yogurt (with active cultures), could be enough to marshal the titanic forces of the gut ecosystem.
There is certainly no silver bullet for obesity or eating healthy, but the ability to dramatically alter metabolism by eating a few ‘good’ bacteria is a tantalizing direction for future research. This research highlights the importance of bacterial populations in the gut, and what a big difference the food we decide to eat can have on our health.
It makes me wonder if our highly processed and irradiated food has lost the rich microbial life that our gut requires to function properly. What do you think?
