Question: how many calories in a handful of pecan nuts?
Answer: 1. A handful goes a long way. Just a single ounce of pecans (about 19 halves) is 200 calories, 3 grams of fiber, 3 grams of protein, and 20 grams of mostly unsaturated fats, making it a hearty, satisfying snack with loads of antioxidants, vitamins, and minerals.
