When I asked why she told me they make you fat, in a matter-of-fact kind of way. What are you allowed to eat? Root vegetables, legumes, anything you can dig out of the ground with your own two hands, and meat. Yea, you may eat of the beasts that walketh upon the earth. So big slabs of meat are okay. No way a ten ounce steak is going to make you fat, but make sure you don't have any big fattening tomatoes with that.
I feel like blaming any one food for being fat is like blaming your parents for everything that went wrong in your life. Yes, of course they were a factor but on balance that doesn't tell the whole story. And I'm no more willing to cut pizza out of my life than I am my parents, even if under the healthy melted cheese and nourishing processed meat there lurks a sauce made of sugar and fattening tomatoes and beneath that — gasp! — carbs. Whisper it... carbs.
