We used to think that nuts were fattening, but now we know better. Research shows that most nuts are filled with good fats, and a proper serving size can help curb your appetite and even help keep your blood sugar more even. The key word here is "moderation." A serving is typically only about half a handful, so be sure to not overdo it.
We love pistachios because you can eat about 40 pistachios for a serving! Make sure you eat raw or dry roasted, because you don't want the extra calories from roasting in oil. Pistachios, anyone?
