Reading these, I'd agree that there's pretty good evidence that animal
derived sat fat causes a small but measurable increase in ... CHD.

What would be the strongest evidence you have seen that shows that
causation?

Jim, let me get back to you on that. My 11-mo old daughter pulled the
cord out of my computer just as Firefox was saving and my bookmarks
are all messed up. And I'm leaving town for a week. I owe you an
answer, OK?

DRT


I requested several of the papers that people keep citing as the basis for
the argument that saturated fat causes heart disease. I've gotten only one
so far, but thought I would comment on it.

Lancet. 1972 Oct 21;2(7782):835-8.
Effect of cholesterol-lowering diet on mortality from coronary heart-disease
and other causes. A twelve-year clinical trial in men and women.
Miettinen M, Turpeinen O, Karvonen MJ, Elosuo R, Paavilainen E.

The treatment used was to replace milk with a soybean oil/skim milk mixture,
and butter and stick margarine with a soft (mostly liquid) margarine in two
mental hospitals. Looking at the paper, I can see that not only were
(certain) saturated fats replaced by (certain) unsaturated fats, as the
authors discuss, but that trans-fats were largely eliminated in the
treatment group. The harmful effects of trans fats weren't known at the
time, and all of the benefit (actually shown clearly only for men) was
attributed to the reduction in saturated fat.

One down.
