To provide the context for those unfamiliar with Taubes' views on the polyunsaturated and saturated fats:

In the Epilogue to Good Calories, Bad Calories on page 454, Taubes notes ten "inescapable" conclusions, the first of which is:[12]

Dietary fat, whether saturated or not, is not a cause of obesity, heart disease, or any other chronic disease of civilization.

(Since most dietary fats are a mix of saturated and polyunsaturated fats, the layman accessible advice would be to cut down on fats, and on the other side, Taubes has to proclaim both to be ok).
