Pistachios contain an array of nutrients that may contribute to heart health. In addition to good-for-you fats, pistachios also have plant-based compounds that may act as antioxidants, including vitamin E, polyphenols, and the carotenoids lutein and zeaxanthin.
Scientific research suggests that pistachios may help to support a strong heart and healthy blood vessels. Studies have shown that adding pistachios to a healthy diet may help to lower levels of oxidized-LDL (bad) cholesterol and other measures of oxidative damage.3 Research has also shown that eating calorie-controlled amounts of pistachios may help to support healthy cholesterol levels.
