I have to tell you about some shocking experiences. They happened right in my own kitchen and in my neighborhood grocery store:

I read nutrition information labels. Suddenly, up was down, in was out, and black was white. And thin was  . . .

Fat.

Oh my goodness. Things that I thought were low fat with high protein were the exact opposite and foods that I thought were low in sugar were high . . .

You get the idea.

My most recent habit is reading nutrition information labels. And boy has it ever paid off.
