The above study is mentioned often. I tried to find it, but it seems that it

I seem to have located a hard copy, along with hard copies of the other
(old) studies that seem to form the basis for the "saturated fat causes
heart disease" mantra. I should have them in about ten days from university
libraries.

The main papers I'm talking about are:
Kinsell LW, Michaels GD, Cochrane GC, Partridge JW, Jahn JP, Balch HE.
Effect of vegetable fat on hypercholesterolemia and hyperphospholipidemia:
observations on diabetic and nondiabetic subjects given diets high in
vegetable fat and protein. Diabetes 1954;3:113-9.
Miettinen M, Turpeinen O, Karvonen MJ, Elosuo R, Paavilainen E. Effect of
cholesterol-lowering diet on mortality from coronary heart-disease and other
causes. A twelve-year clinical trial in men and women. Lancet 1972;2:835-8.
