The selling point of these is that they include three types of grains - brown corn, rice, wheat, and oats. The grain aspects don't translate into lower calories, however, as 55 grams (about 2 oz.) is 254 calories. You can compare this to the average calorie load of potato chips which is about 150 calories per ounce, you're not really saving much on that front. I guess you'll just have to be happy with the whole grain goodness and the fine work it will do on your digestive tract.
