Why is fiber good for your body? Let’s go back a few years. Fiber was big in the mid-1980s, when President Ronald Reagan was diagnosed with colon cancer and Kellogg ran TV commercials saying that high-fiber foods like All-Bran could “reduce the risk of some cancers.”
But the fiber boomlet was soon eclipsed by the (much bigger) oat bran craze, followed by the low-carb bubble, and the whole-grain movement (with scattered mini- fads in between).
Now things have come full circle. Fiber is back. Fiber is showing up in foods because, well, companies have figured out how to put it there, and they know that if they pump up the fiber, people will pull out their pocketbooks.
