To provide a counterpoint:

- Fiber doesn't ward off colon cancer, according to the Harvard School of Public Health: "For years, Americans have been told to consume a high-fiber diet to lower the risk of colon cancer [...] Larger and better-designed studies have failed to show a link between fiber and colon cancer."

- Fiber doesn't reduce the risk of heart disease, according to the American Heart Association: "A fiber supplement added to a diet otherwise high in saturated fat and cholesterol provides dubious cardiovascular advantage." Furthermore, these supplements caused "reduced mineral absorption and a myriad of gastrointestinal disturbances" - factors that in fact, contribute to heart disease.

- Fiber doesn't prevent breast cancer either, according to the U.S. Center for Disease Control and Prevention. In fact, it's the complete opposite: "Carbohydrate intake was positively associated with breast cancer risk." Fiber happens to be a carbohydrate too, and carbohydrates are the only food that contains fiber.

- Fiber doesn't counteract diabetes, according to the Harvard School of Public Health: "Fiber intake has also been linked with the metabolic syndrome, a constellation of factors that increases the chances of developing heart disease and diabetes." Truth is, fiber requires more insulin or drugs to control blood sugar, and makes diabetes even more devastating.

Chiropractors can't quote Harvard or the CDC?


Even the small excerpt seems to be cherry-picking and mischaracterizing research data.


This is why I never listen to advice and opinions on the internet.


Ehhh... your second point merely shows that fiber SUPPLEMENTS don’t help.

Your third point is probably misleading as you can get enough fiber with very modest carb intake

The fourth follows what seems like a similar dubious path to the third
