Studies found that where HDL cholesterol levels were high, arterosclerosis advanced more quickly. So eating cholesterol is bad, right? Eat margerine instead!

Not so fast. Turns out there is no connection between dietary intake of cholesterol and blood cholesterol levels. And after decades of margarine – hydrogenated unsaturated oils – consumption, it turns out margarine is very dangerous to human health. Oops.

It’s not a cure-all. There’s no such thing. But I think coconut oil, olive oil, and fats from nuts (walnuts, almonds especially) in your diet are healthier than consuming temperate crop unsaturated oils for your dietary fats. Even butter and lard are probably healthier – unless they include unhealthy hormones or have been hydrogenated.
