Sure, it may be dangerous. Here's the thing- I've been around for a while and read a lot of stuff in the mainstream media about which combinations of foods will kill you and which will make you immortal. As these have changed over the years and as I have failed to see convincing evidence in the medical literature I have concluded that people have a strong urge to believe that doing something mildly unpleasant (not eating something delicious) now can somehow prevent much worse things in the future. Its the same mechanism and magical thinking that inspired our ancestors to sacrifice goats to appease the gods and assure a great harvest. Wrapping the explanation in scientific jargon is just the latest iteration of a priest in shiny robes.
