Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Effect of pistachio nuts on cholesterol levels

    In 2003, the FDA stated, “Scientific evidence suggests, but does not prove, that eating 1.5 ounces per day of most nuts, such as pistachios, as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease.”

    This study supports that statement.

    First, the details.

    • 15 people with moderately high cholesterol (greater than 210 mg/dL)
    • Randomly assigned to 4 weeks of dietary modification with and without 15% caloric intake from pistachio nuts

    And, the results.

    • On the pistachio diet there was a significant increase in HDL (good) cholesterol.
    • By the end of the study the difference in HDL cholesterol between groups was about 2.3 mg/dL.
    • There were also significant reductions in the following ratios: total cholesterol/HDL cholesterol, LDL (bad) cholesterol/HDL cholesterol, apolipoproteins B-100/A-1.
    • No statistically significant differences in total cholesterol, triglycerides, LDL cholesterol, VLDL-C cholesterol, apolipoprotein A-1, or apolipoprotein B-100
    • No changes in body mass index or blood pressure

    The bottom line?
    In this small study, eating about 2 to 3 ounces per day of pistachio nuts in people with moderately high cholesterol levels who received dietary education and modification resulted in improvement in some lipid values.

    Whether this might also reduce the risk of coronary disease was not shown.

    An earlier study reported that pistachio nuts had a positive effect on blood pressure during stress.
