And.... it turns out that fat is totally harmless. Saturated fat, anyway. What we were blaming on regular fat turns out to have been caused by sugar and trans-fat. Trans fat, or hydrogenated fat, was finally (almost!) banned in the US in 2017. (Although you can still buy Crisco!) Trans fat was invented in the 19th century as a way to get people eating cottonseed oil margarine. When fat got blamed for what sugar was doing, they pretended hydrogenated cottonseed oil, and later other hydrogenated oils, were not at fault.

Even people who have learned that sugar is poison often still believe there is something wrong with fat.

Eggs have plenty of cholesterol. But there is nothing wrong with dietary cholesterol. Your liver makes it for you all day long. Blood cholesterol measurements are about markers for circulatory disease that is not caused by cholesterol.
