Twenty questions on atherosclerosis

Is atherosclerosis a disease affecting all animals or only certain animals?

Atherosclerosis affects only herbivores. Dogs, cats, tigers, and lions can be saturated with fat and cholesterol, and atherosclerotic plaques do not develop (1, 2). The only way to produce atherosclerosis in a carnivore is to take out the thyroid gland; then, for some reason, saturated fat and cholesterol have the same effect as in herbivores.

Are human beings herbivores, carnivores, or omnivores?

Although most of us conduct our lives as omnivores, in that we eat flesh as well as vegetables and fruits, human beings have characteristics of herbivores, not carnivores (2). The appendages of carnivores are claws; those of herbivores are hands or hooves. The teeth of carnivores are sharp; those of herbivores are mainly flat (for grinding). The intestinal tract of carnivores is short (3 times body length); that of herbivores, long (12 times body length). Body cooling of carnivores is done by panting; herbivores, by sweating. Carnivores drink fluids by lapping; herbivores, by sipping. Carnivores produce their own vitamin C, whereas herbivores obtain it from their diet. Thus, humans have characteristics of herbivores, not carnivores.

What risk factors predispose to atherosclerosis?

Risk factors include hypercholesterolemia, systemic hypertension, diabetes mellitus, obesity, low HDL cholesterol, cigarette smoking, and inactivity.

Of the various atherosclerotic risk factors, which one is an absolute prerequisite for development of atherosclerosis?

The answer is hypercholesterolemia. What level of total cholesterol and specifically LDL cholesterol is required for atherosclerotic plaques to develop? Symptomatic and fatal atherosclerosis is extremely uncommon in societies where serum total cholesterol levels are <150 mg/dL and serum LDL cholesterol levels are <100 mg/dL (8). If the LDL cholesterol level is <100??? and possibly it needs to be <80 mg/dL???the other previously mentioned risk factors in and of themselves are not associated with atherosclerosis. In other words, if the serum total cholesterol is 90 to 140 mg/dL, there is no evidence that cigarette smoking, systemic hypertension, diabetes mellitus, inactivity, or obesity produces atherosclerotic plaques. Hypercholesterolemia is the only direct atherosclerotic risk factor; the others are indirect. If, however, the total cholesterol level is >150 mg/dL and the LDL cholesterol is >100 mg/dL, the other risk factors clearly accelerate atherosclerosis.

He says the best diet for humans is a vegetarian fruit diet.

Postgraduate Training After graduating from Emory, and despite his previous experiences in anatomy and surgery, Roberts served as an intern in medicine at Boston City Hospital before pursuing a 3-year residency in anatomic pathology at the National Institutes of Health in Bethesda, Maryland. It was here, working with attending physicians such as Glenn Morrow and Eugene Braunwald that his career began to focus on cardiovascular pathology, and he focused his training exclusively on autopsies and surgical pathology. He also began reading the works of Jesse Edwards, which he credits with helping to develop both his style of writing and strong interests in medical authorship and publications. He next served as a resident on the Osler Medical Service at The Johns Hopkins Hospital in Baltimore before spending an additional year as a fellow in cardiovascular disease at the National Institutes of Health. This extensive training conferred upon Roberts unique credentials both as an anatomic pathologist and a clinically trained cardiologist.

He examined thousands of hearts - do his opinions count for nothing?

Roberts personally canvassed more than a dozen institutions each month to collect heart specimens which he would examine and return with completed autopsy results to their parent institutions. Among those hospitals contributing to his collections were Georgetown, George Washington University, Children's National Medical Center and Johns Hopkins Hospital as well as the Washington, D.C. Veteran's Affairs hospital and National Naval Medical Center. Collectively, Roberts was soon studying more than 50 hearts per month, a twenty-fivefold increase over those available from the NIH alone.

This article is also from 2000...so his "strong association" with cholesterol has largely been shown to be incorrect by now.

I can't take anyone seriously that recommends a fruit-based diet as the road to health. Everything else they say after that is suspect and usually incorrect.

That is an absolute myth, how about Vegans with AS and low to ultra low cholesterol blood levels and intake?

He makes blatant oversimplifications to try and support his predetermined views. Here is a far better analysis with less bias http://www.beyondveg.com/billings-t/comp-anat/comp-anat-6a.shtml in regards to question 2. In answer to question 3 all cause mortality is lowest in the 200-240 range of TC. When your a cardiologist you tend to ignore that there are other nasty little things that can kill you...like cancer or infectious disease.
