On a sort of related note:
I'm in a nutritional study about beef fat and cholesterol. The two
variables they manipulate are consumption of saturated fats and
consumption of poly-unsaturated fats.
The nutritionist doing the study was talking to a bunch of us
subjects about a previous study done in the same format using palm
oil instead of beef fat.
Aparently, they found that saturated fat (specifically palm oil) did
not raise cholesterol levels when equal portions of polyunsaturated
fat were consumed.
If high cholesterol levels increase mortality (which may be false),
then the right combination of fats can increase mortality just as well
as consuming only unsaturated fats.
