David Heinrich  asked the Naked Scientists:
   Hello,
I've heard it said that the only recorded years of reduced heart disease in the U.S. were directly related to the strictest rationing of dairy products during WWII. Is the connection to dairy that strong? Thank you     David

 
What do you think?

Studies on a correlation between lipid rafts and cardiovascular disease have mainly focused on receptor-mediated signalling in endothelial cells of arteries and the heart muscle. In particular, binding of angiotensin II, a peptide that stimulates vasoconstriction and can therefore cause hypertension and pathological hypertrophy, to its receptor (angiotensin II receptor) results in the association of the receptor with lipid rafts in vascular smooth muscle cells (Zuo et al., 2005).

That is not a "link". It is an association.  For example, Lucky Strike cigarettes switched from green packages to white ones because green dye was needed during the war.  Few people hypothesize that using white packages of Lucky Strike lessened heart disease.

The Pennsylvania Amish eat a diet which would make a nutritionist turn pale in a typical modern worker. However, the Amish shun mechanization in running their farms. One does not encounter many lard butts among the Amish. Their cardiovascular risk is not remarkable.

BBC TV had a program about a family raising sheep on a shoestring out in the boondocks. They were short of hands to work the farm. I reckon you could go to work with them and subsist on rashers of bacon without worry.
