ScienceDaily: Pistachios May Calm Acute Stress Reaction

Eating pistachios may reduce your body’s response to the stresses of everyday life, according to a Penn State study.
“A ten-year follow-up study of young men showed that those who had larger cardiovascular responses to stress in the lab, were more likely to contract hypertension later in life,” says Dr. Sheila G. West, associate professor of biobehavioral health. “Elevated reactions to stressors are partly genetic, but can be changed by diet and exercise. Lifestyle changes can make the biological reactions to stress smaller.”

West and her colleagues investigated the effects of pistachios on standardized stressors on subjects who had high cholesterol, but normal blood pressure.
The researchers found that both pistachio containing diets reduced the stress effects on blood pressure, but that the 1.5 ounce pistachio diet reduced systolic blood pressure by 4.8 millimeters of mercury while the 3-ounce pistachio diet only reduced systolic blood pressure by 2.4 millimeters of mercury. The diets had no effect on normal, resting blood pressure.”When we only look at blood pressure, these results are confusing,” says West. “If it is the pistachios, why is it not dose related?”

When the researchers looked at total peripheral vascular resistance, it was clear that the 3-ounce diet caused greater relaxation of arteries.

Those Penn State researchers sure do like pistachios. Then again, so do I.
