"The case for eating steak and cream"
The Economist. When you think about it, we're carnivores; we evolved to eat meat (and at least in most of the West, dairy products, although we haven't been eating butter as long as we've been eating fat). So how likely is it, really, that fat would be harmful? (Except in rare cases....)
I hate wandering around with the nutritionists... Because I'm never sure what's science and what's anti-science. Michael Pollan had it right: "Eat food.* Not too much. Mostly plants." So pass the fat. But have plenty of greens.
NOTE * As opposed to food-like products.
