    Dietary fibre may be defined as anything eaten that the body doesn't digest. So the wax in cheap chocolates could be claimed as fibre, or the invisible filaments in pureed pumpkin could be called fibre. Roughage, I think we know what that is: watermelon seeds, kernel casings, spinach sand.

    Is roughage any good for us?

    It prevents colon cancer and helps keep the food flowing...

    I meant roughage as distinct from the normally broad definition of fibre.

    Roughage may serve the same function as fibre.

    There is a fact about potatoes, for example, that is not widely known. Potatoes are mostly starch, but some of the starch is not digestable. Consequently, that portion of the starch acts like fibre to pass food through the gut, and reduce chances of cancers of the alimentary canal. It also effectively reduces the calorific content of potatoes, making them less fattening, and means that the feeling of satiety from eating potatoes lasts longer.

    It is not fibre, but is still very useful in your diet.

    I followed the link. I'm not taking grants to show that the microwaved, deep-fat fried starch of processed potato products is good for people.

    I'm asking about serious mechanical roughage: apple cores, pomegranate pips, bean strings.
