Since I seem to be in the mood of tackling health issues :D, here is another one:
This article says why whole wheat bread may not be so good for you. Basically it causes a spike in sugar levels. (and seems to do so even more than white bread...) The best option from this point of view is sourdough bread.
I realize it's only one study, but it amazes me how many of the newly created health foods are in fact not so healthy and even dangerous.
I've also read that the amounts of fiber recommended are too high (people used to peel their apples... they still do in some countries like Italy or Japan). However, I have to do more research on the topic before commenting further.
