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 taco (beef, hard shell) the split is:
- Protein: 8.9 g × 4 = 35 kcal — 15% of calories
- Carbohydrates: 19.9 g × 4 = 79 kcal — 35% of calories
- Fat: 12.7 g × 9 = 114 kcal — 50% of calories
- Most of the energy in taco (beef, hard shell) comes from fat (50% of calories).
- It provides 3.9 g of fibre per 100 g, which is a good amount.
- For 200 kcal you can eat about 90 g.
What actually changes the number
A hard-shell beef taco is about 180 kcal, and three make a meal. Soft flour tortilla tacos with cheese and sour cream are closer to 250 each.
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 taco 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.
