A bit concerning is that the authors do not refer to a Cochrane database meta-analysis that showed no effect of fiber in RCT setting. <br /><br />You mention resistant starch. I agree, it is important. In addition, it is also all the other poorly digestable carbohydrates that might be of important, such as polyols (sorbitol, xylitol, ect.), fructans, galactans, even fructose and lactose. These are all fermented to some degree in large bowel and may bring about health benefits in many disease areas but not in IBS. <br /><br />Dietitian Reijo Lpronutritionisthttp://www.pronutritionist.netnoreply@blogger.comtag:blogger.com,1999:blog-8472697.post-75130132046468599262011-11-13T04:25:41.736-05:002011-11-13T04:25:41.736-05:00I wanted to say about this study...
It may well b...I wanted to say about this study...<br /><br />It may well be that fiber (if that's indeed the acting substance) is mitigating the effect of something else they are eating, either by increasing transit time or interacting with gut flora. We know that for some people, foods that cause the release of a lot of bile (fatty foods) irritate the colon. We know that processed meat show up time and again as linked to colon abnormalities. So ... if you could find out what food is problematic, and minimize it, then the benefit you see with cereal fiber may be reduced.<br /><br />This is a difficulty with nutritional reductionism. That is, with investigating the effect of a nutrient in isolation.Bixhttps://www.blogger.com/profile/06263963508785739508noreply@blogger.com
