Nuts make a great snack. They’re full of protein and very tasty. Get the unsalted kind if you’re concerned about sodium. If you’re trying to lose weight, you might want to skip the snack nuts until you’ve reached your weight goals.

You could eat a whole meals’ worth of calories in just a couple handfuls. Here’s a good review on the debate about nuts and weight loss/gain: “Can’t Lose Weight? It Could Be the Nuts.”
Nutritional info is based on roasted unsalted cashews (my favorite!).
