Gut bacteria trained by fiber can reverse fatty liver disease, study shows

A brand new examine from UC Irvine could have lastly found how dietary fiber protects the physique from the injury of sugar, and the way defending your self begins within the intestine.

Researchers from the UCI College of Drugs discovered that inulin, a naturally occurring fiber present in greens equivalent to onions, garlic and artichokes, can reshape the micro organism in your intestine to cease fructose earlier than it reaches your liver.

“We discovered that consuming a sort of dietary fiber referred to as inulin… adjustments micro organism within the intestine to advertise the consumption of dangerous dietary fructose,” stated lead researcher Cholsoon Jang, PhD, of UCI’s Nutrient Metabolism & Illness Lab.

The findings, revealed in Nature Metabolism, reveal a brand new stage of safety that fiber supplies, not solely in digestion, but in addition in the way in which the physique handles sugar at a molecular stage.

Jang and his group found that when folks eat fructose (a standard sugar in fruits and sweetened meals), intestine micro organism within the small gut can metabolize it earlier than it reaches the liver. However with out sufficient fiber, an excessive amount of fructose “overflows,” overwhelming the liver and inflicting fats deposits.

By feeding intestine micro organism with inulin, researchers discovered that the microbes basically burn fructose early, stopping that cascade of injury.

Much more hanging, as soon as these micro organism had been ‘primed’ by inulin, they had been capable of reverse the indicators of fatty liver illness, decreasing fats accumulation and boosting the liver’s pure antioxidants.

Jang says the analysis proves that not all energy are created equal.

He says their work “supplies perception into how fiber protects our well being from dangerous vitamins like fructose.”

The examine centered on non-obese members: individuals who would possibly in any other case fly below the radar however nonetheless face hidden dangers from high-sugar diets.

Jang famous that metabolic injury just isn’t restricted to chubby folks. Even individuals who seem wholesome can expertise liver stress and insulin resistance if their intestine microbes usually are not geared up to course of extra fructose.

“By figuring out particular intestine micro organism and metabolic pathways, our findings can information personalised dietary methods,” Jang stated.

He added that future analysis will examine whether or not different frequent fibers apart from inulin can produce related protecting results.

The implications prolong far past the laboratory. If sure fibers can practice intestine microbes to neutralize sugar earlier than it harms the liver, it may open the door to new remedies for fatty liver illness, diabetes, weight problems and even most cancers.

For now, researchers clarify that the findings point out that fiber not solely aids digestion, however can also be a defender of metabolic well being.

As Jang put it, “For instance, by monitoring how nicely an individual’s intestine micro organism clears fructose earlier than the physique absorbs it, we will select the correct prebiotic or probiotic complement for that individual to enhance outcomes and scale back unwanted side effects.”
