More insight into intestinal flora: no balance means overweight


When we talk about the intestinal flora, one thing has become clear: our gut flora largely determine our weight. They help in the digestion of food and convert it into energy and fat. When the gut microbiome is not balanced, happen -but ongewenste- interesting things with the calories and fats that we eat.

Intestinal flora: prominent determiner

And yet the main focus is to lose weight still on special diets waste, in many variations. In the Netherlands, half the people in 2015 (20+) are overweight and there are several factors that lead to obesity. But there is still quite a prominent factor: the intestinal flora.

Intestinal bacteria, no balance; overweight

Just a few years ago, there is much revealed about the influence of intestinal bacteria on our health. The composition of the unicellular animals out of balance, it affects our immune system, inflammation, autoimmune diseases, allergies and mental health. But also for our weight because the sugar – and fat metabolism else is going smoothly.

The facts come just to light while it was clear some time in cattle. In livestock changes the composition of the intestinal bacteria by means of antibiotics; this makes them thicker and more profitable. This technique has been used since the ’50s.

Interestingly, the story of an autistic boy who got antibiotics for a throat infection. And although his gut flora composition after the treatment was not more diverse, the father noticed his son during and after the treatment was better eye contact and better communicated. The father has since calls for more research into the gut-brain connection. The story read here.

Today, we must try harder to diversity of the gut microbiome. Molecular Metabolism reports that the agricultural changes of the past five decades has affected the diversity of gut bacteria. ( 1)

Social interaction may also help in obtaining diversity, reports an article in Gut microbiota. The interaction forms the intestine microbiome, at least in chimpanzees. ( 2)

Various composition of intestinal microflora is crucial

darmflora4When you eat, you do not just eat there houses trillions of microbial co-eaters in your intestines, which help convert in digestion and nutrients into energy and fat. Can prevent overweight and obesity a diverse composition of the microbial guests. This is not without healthy food. The obesity-related bacteria have only needed one day to invade and the Western diet encourages colonization by. There are also bacteria that discourage colonization: the Bacteroidetes bacteria. ( 3)

Metabolic disorders could be prevented in mice that were eating healthy food, and thus also prevent weight gain and fat storage. The Bacteroidetes takes the upper hand in healthy nutrition and the ‘obesitas’ bacteria (Firmicutes) gets played out. (4 ) In order to lose weight you eat not so much less, just different. ( 5) The microbiome in your digestive tract consists of between 300 and 1,000 different organisms, is fairly stable and varies by person in composition. The intestinal flora are besides overweight and obesity associated with autism, diabetes, cancer, stress, depression and anxiety.

Efficient caloric intake by false alert

Cell Host and Microbe also published research in which animal and human models were examined the mechanism that extracts the amount of calories from food. ( 6) When power supply is scarce, there is less movement in the gastro-intestinal tract. This allows calories to be better absorbed. This protective mechanism did much good for us in the past.

When food is abundant, you would expect that food quickly through the digestive tract, so we absorb fewer calories. But that is not the case.

The importance of short-chain fatty acids

The intestinal bacteria are the organisms that key, then this information to issue to the rest of the digestive system. When certain intestinal bacteria to convert fibers into short-chain fatty acids, a signaling pathway is activated that leaves the stomach and intestines know that power supply amply was present. As a result, power supply will pass more quickly through the gastro-intestinal tract, and there is little time to store calories. If the short-chain fatty acids are scarcely present, slows down the mobility and the body gets the signal that nutrition scarce and more calories must be included. This may also explain why it burns more (abdominal) fat in coconut oil .

MorePrebiotics are indigestible (or non-soluble) fibers which are converted by gut bacteria in the colon to short-chain fatty acids, such as butyric acid, or butyrate. This is also important for the right acidity within the intestines. Butyrate stimulates the growth of lactobacilli and bifidobacteria.

Then what do you eat for healthy gut bacteria


Our gut bacteria make short-chain fatty acids as they get a specific form of complex carbohydrates; prebiotic fibers. Diet rich in prebiotic fiber allows for an increase in short chain fatty acids, which promotes the motility in the gut and thus reduces the calorie intake. Nutrition without adequate amount of prebiotic fibers, such as today, leads to a decrease of short-chain fatty acids, and an improved absorption of fats and calories ( 7) ; something we are waiting not most of us.

Here is also the problem: the typical Western diet provides a lot of calories and little prebiotic fibers. So despite our enormous calorie consumption, the signal that we starve. This makes our digestive system to collect all calories. ‘Knowledge is power’ is sometimes said, but may know … his weight loss in this case. our distant ancestors estimated daily consumed 120 grams of prebiotic fiber. So we can take advantage of this knowledge and use it to take control of our weight.
