How these high fiber foods could naturally stop Crohn’s flare-ups

Posted February 16, 2014

It’s been a few years since researchers published findings that eating broccoli and plantains could be good medicine for Crohn’s disease and ulcerative colitis. But how many doctors have recommended the food as a dietary approach to quell symptoms of irritable bowel disease (IBD)? Much has been published about the role of diet for treating IBD, but sometimes the important of eating specific foods gets lost in the shuffle, so to speak.

Investigating the fiber of our being: How our gut bacteria metabolize complex carbohydrates from fruits, vegetables

Posted February 13, 2014

We are all aware of the health benefits of dietary fiber. But what is dietary fiber and how do we metabolize it? Researchers begun to uncover how our gut bacteria metabolize the complex dietary carbohydrates found in fruits and vegetables. Trillions of bacteria live in human intestines — there are about ten times more bacterial cells in the average person’s body than human ones. Known as “microbiota,” these bacteria have a vital role to play in human health: they are central to our metabolism and well-being.

Most Americans Still Falling Short of Dietary Whole Grain and Fiber Requirements

Posted February 6, 2014

It comes as no surprise that with all the sugarcoated cereals and pastries lining our supermarket shelves, that we in the U.S. are getting less than the recommended amounts of whole grains and dietary fiber. That’s the conclusion drawn by Marla Reicks, PhD., who led a new study (abstract here) at the University of Minnesota in St. Paul. Note her co-authors are all affiliated with General Mills, which funded the study.

Study illuminates how humans digest fibre

Posted January 31, 2014

New insight into how gut bacteria digest fibre could lead to advances in areas as diverse as health and environmentally-friendly biofuels. Fibre is an essential part of a healthful diet, but our ability to benefit from it is entirely dependent the bacteria living in our intestines. An international research team, which included scientists at KTH Royal Institute of Technology, recently uncovered how one group of bacteria digest a major type of dietary fibre.

A versatile gut bacterium helps us get our daily dietary fiber

Posted January 21, 2014

University of British Columbia researchers have discovered the genetic machinery that turns a common gut bacterium into the Swiss Army knife of the digestive tract – helping us metabolize a main component of dietary fibre from the cell walls of fruits and vegetables.

Versatile gut bacterium identified that helps us break down dietary fiber

Posted January 20, 2014

The human digestive tract is inhabited with roughly 100,000,000,000,000 microorganisms, which amazingly accounts for 50% of the weight of the contents of the lower digestive track. The daily caloric intake that comes from the breakdown of dietary fiber buyer gut bacteria approaches 10%. Researchers from the University of British Columbia, teamed up with the University of Michigan, the University of York and the Swedish Royal Institute of technology to discover how a common gut bacterium helps us metabolize a main component of dietary fiber from the cell walls of fruits and vegetables.

Anti-hyperglycemic activity of Centella asiatica is partly mediated by carbohydrase inhibition and glucose-fiber binding

Posted January 20, 2014

Centella asiatica (C. asiatica) was previously reported to have anti-hyperglycemic effects in animal diabetic model rats. However, its activity on organ and tissue level remains unstudied. Our study aims at exploring the possible effects, C. asiatica extract and insoluble fiber has on carbohydrate absorption, insulin secretion, insulin sensitivity and glucose utilization.

Vitamin B3, fiber ‘protects against colon cancer and inflammation’

Posted January 20, 2014

Previous research has suggested that a diet rich in fiber may reduce the risk of colon inflammation and cancer. But new research suggests that niacin, also known as vitamin B3, may also help protect against these conditions.

How fiber prevents diabetes and obesity

Posted January 17, 2014

Scientists have known for the past twenty years that a fiber-rich diet protects the body against obesity and diabetes but the mechanisms involved have so far eluded them. A French-Swedish team including researchers from CNRS, Inserm and the Université Claude Bernard Lyon has succeeded in elucidating this mechanism, which involves the intestinal flora and the ability of the intestine to produce glucose between meals.

How a fiber-rich diet protects against obesity and diabetes

Posted January 16, 2014

Researchers have long known that a diet rich in fiber can help protect against diabetes and obesity, but they have been unclear as to how. Now, investigators from France and Sweden say they have unveiled this mechanism. This is according to a study recently published in the journal Cell.
