Diet, Microbes, IBD:Lessons from Japanese foods

Even though this article was pretty interesting I was amazed at the fact that it really didn't say anything conclusive at all. In it's conclusion it said "Although the incidence of IBD in developed Asian countries is rapidly increasing, so is the incidence in developed Western countries". There really isn't any proof or evidence implicating anything specific, even though the article mainly talks about diet.

It also said early on that "Dramatic changes in the environment, resulting in the dysregulated composition of intestinal microbiota or dysbiosis, *MAY* be associated with the fundamental causes of IBD. Japan now has upgraded water supply and sewerage systems, as well as dietary habits and antibiotic overuse that are similar to such features found in developed Western countries". This could be interpreted to mean that IBD has nothing to do with eating a "Western Diet" at all and 100% due to the other factors listed such as the overuse of antibiotics, antibacterials, and other environmental factors. The study doesn't really prove or determine any one particular cause of UC one way or the other. Maybe one day they can isolate out which of these several different scenarios are more responsible for IBD or whether they work together in concert.
