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 green beans (boiled) the split is:
- Protein: 1.9 g × 4 = 8 kcal — 18% of calories
- Carbohydrates: 7.9 g × 4 = 32 kcal — 76% of calories
- Fat: 0.3 g × 9 = 3 kcal — 6% of calories
- Most of the energy in green beans (boiled) comes from carbohydrate (76% of calories).
- It provides 3.2 g of fibre per 100 g, which is a good amount.
- It is 89% water, which is why it is so light for its size.
- For 200 kcal you can eat about 570 g.
What actually changes the number
Green beans are 35 kcal per 100 g cooked and a large side portion is under 60 kcal. Almondine or buttered versions carry most of their calories in the almonds and butter.
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 green beans 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.
