Pistachios are the most slimming nuts, with less than four calories each. Their shells make them especially dieting-friendly: “Eating them in the shell automatically slows down your pace so the snack lasts longer and you eat less overall,” says Bauer. They may also help you breathe easier: University of Texas M. D. Anderson Cancer Center researchers found that eating two ounces of pistachios daily may reduce lung cancer risk. Pistachios are rich in the antioxidant gamma-tocopherol, a form of cancer-fighting vitamin E. Pistachios are also packed with potassium, a mineral essential for a healthy nervous system and muscles, and are a good source of vitamin B6, which can lift your mood, fortify your immune system, and more.
