The evidence that hydrogenated oils are bad for you is as clear and 
convincing as that which suggests smoking is unhealthful. There is 
*lots* of good science - more than 3400 journal publications in the 
past five years alone.  

We've known that there's a problem with trans acids since those 
canadian studies in the 1970s.  At this point, we're not finding out 
*whether* it causes health problems, but *which* health problems it 
causes, and *why*.

Right now, I'm leaning towards a connection to diabetes, through a cis-
9, trans-11 conjugated linoleic acid link.  Dietary CLA mostly comes 
from the fat of beef and pork that's grass-fed - but grass-fed 
livestock is increasingly uncommon, and leaner livestock is being 
raised.  If you graph the consumption of CLA with the incidence of Type 
2 diabetes, it is rather spooky, and both Purdue and Penn State have 
animal studies showing a relationship between dietary c9t11CLA and Type 
2 diabetes.  

Cis-9, trans-11 CLA is a significant anti-carcinogen. It alters the 
fatty acid composition of biological tissues in a manner that increases 
their oxidative stability.  Cancer cells may become enriched in CLA 
during growth, making intracellular lipids more susceptible to ordinary 
levels of oxidative stress, to the point of producing a cytotoxic 
effect.
