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 kidney beans (boiled) the split is:
- Protein: 8.7 g × 4 = 35 kcal — 27% of calories
- Carbohydrates: 22.8 g × 4 = 91 kcal — 70% of calories
- Fat: 0.5 g × 9 = 5 kcal — 3% of calories
- Most of the energy in kidney beans (boiled) comes from carbohydrate (70% of calories).
- It provides 6.4 g of fibre per 100 g, which is a good amount.
- For 200 kcal you can eat about 155 g.
What actually changes the number
Kidney beans are 127 kcal per 100 g cooked. The chilli they go into is where the calories vary: the beef, the oil and the cheese on top matter more than the beans.
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 kidney 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.
