Vegetarians and Their Superior Blood

48

In addition to the seven controlled trials (where you bring in people and change their diets, then compare them with a control group eating everything), the researchers also reviewed 32 different observational studies. Those are less scientifically valid than controlled studies, but they showed even larger decreases in blood pressure between vegetarian and omnivorous diets (6.9 systolic, 4.7 diastolic).

“It’s not uncommon for us to see patients at our research center who come in and they’re taking four drugs for their blood pressure, and it’s still too high. So if a diet change can effectively lower blood pressure, or better still can prevent blood pressure problems, that’s great because it costs nothing, and all the side effects are ones that you want, like losing weight and lowering cholesterol.”

The research center to which Barnard refers is that of Physicians Committee for Responsible Medicine (PCRM). Barnard is president. Founded in 1985, PCRM describes itself as an “independent nonprofit research and advocacy organization.” The advocacy is for ethical human and animal experimentation. According to its website, PCRM “promote(s) alternatives to animal research and animal testing. We have worked to put a stop to gruesome experiments, such as the military’s cat-shooting studies, DEA narcotics experiments, and monkey self-mutilation projects.”

“Neal is a good guy and does good work,” Dr. David Katz, Director of Yale University’s Prevention Research Center, told me, “but the name of the organization is entirely misleading. It is not about responsible medical practice. It is entirely and exclusively about promoting vegan eating. A laudable cause to be sure, but I prefer truth in advertising.”
