I really appreciated this blog by David Zincenko and Matt Goulding, authors of Eat This, Not That.
It talks about supposedly healthy foods that are lined with corn syrup or full of fat. Like granola bars -- held together by high-fructose corn syrup. Or bagels -- up to 700 calories if you get the schmear (and I always get the schmear!).
I really appreciate blogs like these. I get totally suckered into thinking, "oh it can't be that bad," and basically ignoring the facts or calorie counts.
However, I almost always come across blogs like these at the wrong time -- like how I just bought a huge box of granola bars. :)
