Does eating fiber by itself reduce mortality? Or do healthy and wealthy people with active lifestyles and excellent healthcare happen to also eat more fiber?

- e584 11mo agoOh wow, I'm sure the authors of the meta study never considered that...
- brandonb 11mo agoThis is honestly a limitation of nearly all nutrition research -- it's based on observational data. Part of the reason we expect fiber to reduce mortality, rather than simply being a marker of other factors correlated with mortality, is that we can identify physiological mechanisms. For example, for cardiovascular mortality, fiber reduces LDL cholesterol / ApoB which lowers heart attack and stroke risk.
