Is That Right? Pistachios are lowest-calorie, lowest-fat nut?
You can't blame the folks who sell pistachios for trying hard to boost the nuts' image. The recalls of pistachios potentially contaminated with salmonella earlier this year surely put a big dent in both sales and the nuts' reputation.
But the new ad campaign for Wonderful Pistachios may be relying on a bit of subtle wordplay when it says pistachios are "lowest calorie" and "lowest fat" nuts. The absence of the word "the" should clue you in: Pistachios are really among the lowest-calorie, lowest-fat nuts.
According to a chart prepared by the International Tree Nut Council Nutrition Research & Education Foundation in April, almonds, cashews and pistachios each have 160 calories per ounce. That one-ounce serving amounts to 24 whole almonds, 49 pistachios or 14 walnut halves. (Another comparison chart presented on a pistachio-promotion site but drawn from U.S. Department of Agriculture figures says pistachios and cashews have 160 calories but walnuts have 190.)
As for fat content, pistachios and cashews each have 13 grams of total fat per ounce, making them the two lowest-fat nuts in the bunch (which includes almonds, brazils, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts).
Of that total fat, in pistachios 1.5 grams is of the unhealthful saturated variety; that number applies to hazelnuts, pine nuts and walnuts, too. Almonds have just a gram of saturated fat, pecans 2 grams, macadamias 3.5, and brazils 4.
But being low in unhealthful fat is only part of the picture; nuts are among the foods valued for their good-for-you monounsaturated and polyunsaturated fats -- the kind we're encouraged to eat in place of saturated and trans fats. Pistachios have a respectable 7 grams of monounsaturated fats, more than walnuts' 2.5 grams but much less than macadamias' 17 grams. And while pistachios deliver 4 grams of polyunsaturated fats, an ounce of pine nuts contains 10 grams and walnuts 13 grams.
Quibbles aside, no way am I looking to discredit pistachios. Like other tree nuts, they're a fantastic, fiber-rich, filling alternative to sugary sweets; especially if you choose unsalted nuts, they're much better for you than potato chips, pretzels or other savory packaged snacks. And pistachios are in fact distinct from other tree nuts in that they contain much more of the antioxidants Vitamin A, beta carotene, lutein and zeaxanthin.
So eat lots of pistachios, and enjoy every bite. Just don't pick them because you think they're lower in calories and fat than any other nut on the tree.
