There's a loading screen tip in WoW that I like: Remember to take all things in moderation (even World of Warcraft!)
And this is true with, pretty much everything. White bread is not as healthy as whole grain (and not as tasty) but it won't kill you. Just don''t eat too much. These foods are fine, in certain amounts.
And how do I take these articles? As anyone should: with a grain of salt and a healthy dose of skepticism.
