Can anyone help me figure out how to get the full article to this abstract 
on-line?  I think the question raised at the end of the abstract is very 
interesting for those of us trying to approximate a paleo diet.

Reducing the serum cholesterol level with a diet high in animal fat.Newbold 
HL.
Multiple food allergies required a group of seven patients with elevated 
serum cholesterol levels to follow a diet in which most of the calories 
came from beef fat. Their diets contained no sucrose, milk, or grains. They 
were given nutritional supplements. This is the only group of people in 
recent times to follow such a diet. During the study, the patients' 
triglyceride levels decreased from an average of 113 mg/dl to an average of 
74 mg/dl; at the same time, their serum cholesterol levels fell from an 
average of 263 mg/dl to an average of 189 mg/dl. At the beginning of the 
study, six of the patients had an average high-density lipoprotein 
percentage of 21%. At the end of the study, the average had risen to 32%. 
These findings raise an interesting question: are elevated serum 
cholesterol levels caused in part not by eating animal fat (an 
extremely "old food"), but by some factor in grains, sucrose, or milk ("new 
foods") that interferes with cholesterol metabolism?
