Part of the issue has got to be the oversupply of specific, yet mostly useless advice. Should we really expect people to decide to consume any (almond, peanut, olive, coconut, sesame, palm, soybean, corn, safflower, etc.) oil based on the relative amount of saturated fat?

I've tried to explain what polyunsaturated fats are to my mom, many times, when she's trying to decide to use olive oil or something else. The news stories on TV, Dr. Oz, Oprah, etc. have convinced her that's worth worrying about.

I'm much happier with simple, broad advice. "Eat food, not too much, mostly plants." (Regardless of how you feel about Pollan.)
