Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For potato chips (plain, salted) the split is:
- Protein: 6.4 g × 4 = 26 kcal — 5% of calories
- Carbohydrates: 53.8 g × 4 = 215 kcal — 39% of calories
- Fat: 34 g × 9 = 306 kcal — 56% of calories
- Most of the energy in potato chips (plain, salted) comes from fat (56% of calories).
- It provides 3.1 g of fibre per 100 g, which is a good amount.
- For 200 kcal you can eat about 40 g.
What actually changes the number
Crisps are 532 kcal per 100 g, a third of it oil. A small 28 g bag is 150 kcal; a sharing bag of 150 g eaten across an evening is 800 — and the photograph of an empty bag is worth taking.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of potato chips as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.
