Are You Taking Bad Fiber Supplements?

In clinical trials, fiber is really effective at doing all of the good health things that fiber generally does for people. But in observational studies where it's not under controlled circumstances, you're just looking at what people do naturally out in the wild. High heat, um, uh, hydrolyzation, the kinds of things that you would do in a factory setting to make a product that's standardized and doesn't taste like anything and isn't gross. That can reduce the gel formation properties of the fiber supplements.
