Gut Bacteria Can Control Diabetes 271
Shipud writes "Insulin resistance is the harbinger of metabolic syndrome. Insulin resistance is when the body cannot use insulin effectively. As a result, blood sugar and fat levels rise. Therein lies the path to morbid obesity, diabetes, stroke, and heart problems. A group of Brazilian researchers have taken a strain of mice normally known to be immune to insulin resistance, and made them insulin resistant (pre-diabetic) by changing their gut bacteria. They then gave the mice antibiotics, and by changing their gut bacteria again, reversed the process, curing them of the disease. Their research shows just how influential the bacteria living in our gut can be on our health."

That's not pedantic - it's a simple fact that seems to be lost on people. Sure, there are factors like diabetes and glandular issues that can make it easier to put weight on... but you still have to eat more than you use!

There is, genetic being one of the big ones. Along with diet, age, obesity, thyroid, medication related, pregnancy, etc. And where it's genetic and it's childhood inflicted, a lot of diabetics still hold out for partial pancreas transplants or something else, otherwise it's live with it. It does work, but compatibility is the real pain. A lot of people though these days it's simply age + lifestyle. Then again, they've changed the definition of what diabetic is too. What was diabetic 10 or even 20 years ago, isn't what it is today. So a whole new broad range of people fall into it.

Actually, you can transplant human gut bacteria to treat disease. It's called Fecal Bacteriotherapy [wikipedia.org]. It's a procedure carried out under the supervision of a doctor where you put a donor's shit up your ass. Unappealing certainly, but at least it's not 2girls1cup style.

In summation, what they discovered is that the micro-organisms that live in your intestines play a role in whether or not you develop Type 2 diabetes.

Got it backwards. Getting the right bacteria can apparently cure diabetes, or at least remove the symptoms. Killing all the bacteria with an antibiotic won't magically introduce the correct bacteria. (I retained the plural because it's not clear if there is just one strain, or if they have to work together with others)
There is no 'reset' with bacteria, only killing some or nearly all and hoping you get the right replacements. You have to put the right ones in there.

There are over-the-counter Lactobacillus acidophilus tablets that contain cultured bacteria already. Why in the world would anyone do it the way you describe? I suppose there are other helpful bacteria in your gut, but that seems to be the most significant variety in terms of its effect on everything from serum cholesterol levels to lactose intolerance....

Fun fact - Koalas eat eucalyptus (gum tree) leaves, which are pretty toxic to all other animals. They have a special bacteria in their gut which helps break the toxin down. Guess how the bacteria is passed on to the next generation?

While eating less saturated fat is a good step it is not a solution and eating lots of any oil is bad, and not a serious issue unless you have high cholesterol(which can also be controlled with exercise). Eating whole grain bread and other goods as a substitute for white-bread and processed carbohydrates does spread out the sugar release and help to control hunger pangs and chocolate cravings, but you are supposed to swap them in as a substitute not eat "lots" because they are healthy which is counter-productive. I have in short never heard a real expert advocating the diet you are proposing it is an oversimplified caricature, but one oftern peddled by semi uniformed "nutritionists".

As long as their is something to digest in your gut, their will be gut microbes. And considering that many of the gut microbes survive primarily on Host synthesized mucus carbohydrate or sloughed Host enterocytes, I'm tempted to call "Bull Shit!" on the entire premise you are suggesting.
The appendix is a regressed cecum. The cecum, in species where it is not regressed, it is a site of fermentation of dietary fiber for the production of volatile fatty acids like Acetic, Proprionic, and Butyric acid, which are then absorbed in the cecum. During fermentation amino acids and vitamins are also synthesized, but are unavailable for absorption in most species. Notable exceptions being poultry, who use reverse peristalsis to push cecal digesta back into the small intestine (primary site of nutrient absorption), and some animals like rabbits who excrete what is called a "Night pellet" consisting primarily of cecal digesta which is then ingested orally, giving the small intestine a second attempt to absorb these cecally derived nutrients.
The key being that the microbiota profile of the cecum, in species where it is fuctional, is very different from the microbiota profile of the small or large intestine.
