Methodology & Nutrition Data Sources — Grilled Zucchini
How we calculate Grilled Zucchini nutrition facts: We estimate recipe nutrition from ingredient weights, per-100g food data, and the stated serving count. Values are planning estimates, not lab-tested nutrition labels, because brands, produce size, trimmed weight, and how much oil stays on the pan can change the final number.
- Calories (66 kcal/serving): Ingredient calories are summed for the full batch, then divided by 4 servings.
- Protein (2g): Protein grams come from the listed ingredients, not from a generic "healthy recipe" target.
- Carbohydrates (7g): Carbohydrate estimates include naturally occurring carbs in vegetables, grains, fruit, dairy, and sauces where applicable.
- Fat (4g): Added oil, butter, nuts, seeds, cheese, dressings, and fattier proteins can move this number materially.
- Fiber (2g): Fiber is estimated from whole-food ingredients and rounded to practical food-log precision.
