Although from Western Asia originally, pistachios have been eaten for thousands of years throughout the Mediterranean. Nuts in general are a great source of protein and healthy fats, but did you know that pistachios have numerous additional benefits? Scientists have found these little tough nuts to be useful in preventing cancer, lowering lipids in the prevention of heart disease, and preventing diabetes, all while delivering a good source of antioxidants. And these aren’t the only health benefits of pistachios.
Outlining the Health Benefits of Pistachios
A study published by the American Association for Cancer Research indicates that people who ate about 2 ounces of pistachios a day for four weeks saw higher blood levels of gamma-tocopherol, a type of vitamin E. Gamma-tocopherol is known to protect against various cancers, including lung cancer. A powerful fat-soluble antioxidant, the vitamin E in pistachios is also essential for beautiful skin, protection from UV radiation damage, and strengthening cell membranes.
Another study found that eating pistachios lowered lipids and lipoproteins, a risk factor for heart disease. The researchers report that “Inclusion of pistachios in a healthy diet beneficially affects cardiovascular disease risk factors in a dose-dependent manner, which may reflect effects on Stearoyl CoA Desaturase (SCD). “ Penny Kris-Etherton, professor of nutrition and primary investigator of the study also says: ”our study has shown that pistachios, eaten with a heart healthy diet, may decrease a person’s CVD risk profile.”
According to research published in the Journal of Nutrition, a diet rich in pistachios (1.5 to 3 ounces per day) was linked to increased beta-carotene and gamma-tocopherol in the blood.
