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 sour cream the split is:
- Protein: 2.4 g × 4 = 10 kcal — 5% of calories
- Carbohydrates: 4.6 g × 4 = 19 kcal — 9% of calories
- Fat: 19.4 g × 9 = 174 kcal — 86% of calories
- Most of the energy in sour cream comes from fat (86% of calories).
- For 200 kcal you can eat about 100 g.
What actually changes the number
Sour cream is 198 kcal per 100 g, so a tablespoon on a baked potato or taco is about 25 kcal. A restaurant dollop is more like three tablespoons.
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 sour cream 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.

Can I track sour cream by taking a photo?
