Maar komt het dan niet door de extra magnesium? Suikerpatienten hebben bijna altijd een enorm magnesium tekort.
En de extra vezels zullen ook nog wel zorgen voor een iets gelijkmatiger opnemen van de suikers.
Hoe dan ook ik geloof er niet (meer) in. Nu ik vezels mijd als de pest heb ik voor het eerst in tientallen jaren een normale ontlasting zonder buik en darmklachten.
Dr. Eades heeft hier een keer een uitstekende blogpost over geschreven:
Quote:
Into our bowel-regularity-worshipping society there has come a substance that ensures regularity. It’s called fiber. It is sold everywhere in diverse forms. All manner of ‘experts’ from our doctors to our grandparents encourage us to consume plenty of fiber. If we can’t get enough from the foods we eat to achieve regularity, we are encouraged to buy supplements. Everyone is on the regularity bandwagon and, by extension, the fiber bandwagon. The much despised Jane Brody has written countless times on the virtues of fiber, WebMD encourages us to get our share, even C. Everett Coop exhorts us to keep the fiber coming. And, despite numerous studies showing that fiber doesn’t really do squat for us healthwise, everyone continues to recommend it.
To paraphrase John Huston: Evidence? We ain’t got no evidence. We don’t need no evidence. We don’t have to show you any stinking evidence.
Into this society of bowel movement lovers a researcher comes along and writes a paper showing how fiber causes an increase in regularity. Our intrepid researcher’s name is Dr. Paul L. McNeil; he is a cell biologist at the Medical College of Georgia. I’ll let him tell how it all works.
When you eat high-fiber foods, they bang up against the cells lining the gastrointestinal tract, rupturing their outer covering. What we are saying is this banging and tearing increases the level of lubricating mucus. It’s a good thing.
Indeed?
He goes on:
It’s a bit of a paradox, but what we are saying is an injury at the cell level can promote health of the GI tract as a whole.
Really?
He goes on to explain that even though epithelial cells usually live less than a week, they are regularly bombarded, in most of us at least three times a day, as food passes by.
These cells are a biological boundary that separates the inside world, if you will, from this nasty outside world. On the cellular scale, roughage, such as grains and fibers that can’t be completely digested, are a mechanical challenge for these cells.
But in what he and colleague Dr. Katsuya Miyake view as an adaptive response, most of these cells rapidly repair damage and, in the process, excrete even more mucus, which provides a bit of cell protection as it eases food down the GI tract.
As reported in ScienceDaily
In research published in 2003 in Proceedings of the National Academy of Sciences, Dr. McNeil showed proof of his then decade-old hypothesis that cells with internal membranes use those membranes to repair potentially lethal outer-membrane injuries. A recent paper published in Nature in collaboration with Dr. Kevin Campbell’s laboratory at the University of Iowa showed how human disease, including certain forms of muscular dystrophy, can result from a failure of this mechanism.
An outer membrane tear is like an open door through which calcium just outside the cell rushes in. Too much calcium is lethal but that first taste signals the vulnerable cell it better do something quick. With epithelial cells, several of the internal mucus-filled compartments fuse together within about three seconds, forming a patch to fix the tear. In the process the compartments expel their contents so, almost like a bonus, extra mucus becomes available to lubricate the GI tract.
And a final telling paragraph.
The scientists aren’t certain how many times cells can take a hit, but they suspect turnover is so high because of the constant injury. Potentially caustic substances, such as alcohol and aspirin, can produce so much damage that natural recovery mechanisms can’t keep up. But they doubt a roughage overdose is possible.

So, we have a situation where a product causes damage to the cells lining a tube, causing them to produce a lot of mucus in an attempt to protect themselves. In the process many of these cells die and are replaced by new cells. And this is perceived as a good thing.
My question is: is it really a good thing?
