I LOVE cashew nuts.
To me, they are a good car companions, as a snack. When you get a little tired, take three or four of them, and you'll be fine again, better than coffee.
Getting fat on cashew nuts, you can make a fatty sauce out of any nut, including cashews and peanuts, but cashews aren't really meant for that. They have high protein content which is said to be good for your brain.
