Lack of fruits/vegetables and specifically the subsequent association with lack of fiber intake is often blamed on the increasing prevalence of crohn's disease. Especially after a study a few years ago came out suggesting lack of fiber intake was associated with later development of crohn's disease. In Japan this theory is also popular, supposed Western diets are the cause of the increase in crohn's disease by some.
I have posted 2 large-scale studies in the past that debunked this theory and where no negative association with fruits/vegetables and fiber intake and the prevalence of crohn's disease was found. But this theory that high fiber intake is protective against onset of crohn's disease keeps being parroted. Studies were prebiotics like inulin worsen disease activity are often ignored. Not to mention the complete lack of fiber in EN.
This data was in the news lately, an OECD study that shows fruits, vegetables and dietary fiber intake of individual OECD countries. Even though the data is self-reported, almost all these studies are self-reported. The fact it is a combination of 2019 Eurostat and EHIS data makes it pretty much the most reliable large-scale data you can find.
Countries with high intake of fruits/vegetables do not have lower incidence of crohn's disease. Quite the opposite, prevalence of crohn's diseasse is the highest in the world in Canada. In Europe, the UK, northern France, the Netherlands and Denmark have the highest rates of crohn's disease. These countries have some of the highest intake of fruits/vegetables and as I showed in previous discussions, fiber. The only outlier being Sweden. Eastern European countries and mediterranean countries have surprisingly low intakes of fruits and vegetables, and very low incidence of crohn's disease.
This supposed link between vegetables, fruits and fiber intake and negative incidence of crohn's disease, is very questionable.
