The idea that diverticulosis is caused by insufficient fiber intake is not supported by literature; higher fiber intake is associated with more diverticulosis.

“there are multiple studies that show that there is no benefit to fiber for reducing diverticulosis and in fact there have been some studies which show that as people eat more fiber people develop more diverticulosis and these are Association studies we can't claim complete causation but I talked about this study in the debate with Lane as well the study I will quote people but they did colonoscopy on people and they looked at the amount of fiber people were eating by quartile and what they saw was that as people ate more fiber they tended to have more diverticulosis the name of the study is a high-fiber diet does not protect against asymptomatic diverticulosis and in fact what they found was that people had more diverticulosis and they said compared to individuals with less than 7 bowel movements per week individuals with greater than 15 bowel movements per week had a 70% greater risk for diverticulosis uh-oh so I don't think this definitely says that fiber is causing diverticulosis but it's these type of studies that raise into questions strongly the idea that fiber has any protective value for diverticulosis”

“the studies do not suggest that fiber is beneficial for diverticulosis”

“so Berkut was probably completely wrong about fiber and diverticulosis but that's why we've been told that's the fiber fairytale”

“and unfortunately why not the the equatorial Sun why not Western eyes food right like why not the absence of a highly refined westernized diet which causes dysbiosis with an inflammation what we are actually now learning is that diverticulosis is not a disease pressure because people can get diverticula in the right : so if you look at the colon there's there's the right side which is where the appendix is the cecum it goes across the transverse then it goes down on the left side and then you get the sigmoid colon in the rectum well the pressures are high on the left side of the colon but the right side of the colon is actually pretty big and and and dilated and there's not a lot of pressure there and people can get right-sided I reticula as well”

“there's no evidence that fiber improves diverticulosis that is a misconstrued story from surgeon named Berkut in the 1960s but if you look at the data actually in terms of case series which are based on food frequency recall questionnaires with colonoscopy the people that ate the smallest amount of fiber had the lowest amount of diverticulosis”

“fiber and diverticulosis is similarly sort of a Pied Pipers tale probably starting with Denis Burkitt in the 1970s going to Africa and seeing a lower incidence of diverticulosis”

“there's actually a negative correlation between increasing amounts of fiber well actually should say positive correlation increasing amounts of fiber and increasing amounts of diverticulosis so it's pretty clear that fiber doesn't prevent diverticulosis”

“a lot of people would think oh diverticulosis is you don't have enough fiber but there's actually no literature to support that that connection yes even worse people who eat more fiber are more likely to have diverticulosis and there's a large and yeah there's a large endoscopy study I think of over 3 000 patients that found that people who ate the most fiber had the most incidence of diverticulosis”
