Raw pistachios are simply the unroasted version of the popular nut, which means they haven’t been heated or seasoned. They come in their natural, brownish skin and are typically sold with the shells still on. Unlike roasted pistachios, raw ones retain their natural flavor and more of their nutrients since they haven't been exposed to heat, which can break down some of the vitamins and antioxidants. Flavor-wise, raw pistachios have a slightly milder, more delicate taste compared to roasted ones, and they’re known for their buttery, slightly sweet flavor. They also have a vibrant green color inside, which is part of what makes them so visually appealing. Nutritionally, pistachios are rich in healthy fats, protein, fiber, antioxidants, and essential vitamins like B6 and copper. They're also a great snack for anyone looking to add more heart-healthy foods to their diet.
