“Not even a question that should come up” is a pretty sour attitude to take in general, and I don’t even think you’re right. Fiber does have a health impact as you say, and having good health is one of the main ways known to delay death. And what is survival but the delay of death? My point is that by eating a larger variety of nutritious food, you are less likely to suffer from poor health due to a lack of something you need.
