How many calories are in a green apple?

Estimate87–128 kcal

150–220 g cored Granny Smith with skin

Granny Smith with skin is a specific green-apple proxy. Generic raw apple with skin is shown only as a comparison; not every green apple is Granny Smith.

Calculated from USDA per-100-g values and the disclosed edible weights. This is an estimate, not brand or official product nutrition. These are scenario ranges, not confidence intervals; actual food can fall outside them.

Which apple does the range describe?

The headline range uses only the Granny Smith record and 150–220 g edible weight. The generic-apple comparison is kept separate so a color description does not silently become a claim about every cultivar.

Skin, core and preparation

Weigh the flesh and skin you eat after coring. A different cultivar, peeled apple, cooked apple or added sugar needs its own matching entry.

USDA records: compare the same edible weight

Each reference row is per 100 g. Food states and alternatives stay separate. Additional soda rows use the recorded can weight. Missing nutrients stay Unknown; a displayed zero can be a small value rounded to one decimal.

Portion scenarios and calculation

Assumptions: 150–220 g cored Granny Smith with skin. These weights are editorial models unless explicitly labeled USDA portions. Choose one alternative for each component; do not add alternative recipes together.

For every nutrient: USDA amount per 100 g Γ— edible grams Γ· 100, summed across ingredients. The range is the minimum and maximum across the disclosed record alternatives and weight endpoints, calculated before rounding. Calories use whole kcal; g and mg use at most one decimal, with decimal ROUND_HALF_UP and no trailing zeros.

  • 87 kcalFDC 168203 Γ— 150 g
  • 128 kcalFDC 168203 Γ— 220 g

Combined scenario ranges: protein 0.7–1 g; fat 0.3–0.4 g; carbohydrate 20.4–29.9 g; fiber 4.2–6.2 g; total sugars 14.4–21.1 g; sodium 1.5–2.2 mg. Nutrient minima can come from different alternatives, so the low values do not necessarily describe one meal.

Plan the portion alongside other foods

Use a matching preparation and edible weight when logging each part of a meal. These guides explain separate foods or drink choices; their portion estimates are not interchangeable.

Common questions

Green apple calories?

Granny Smith with skin is a specific green-apple proxy. Generic raw apple with skin is shown only as a comparison; not every green apple is Granny Smith.

How is this estimate calculated?

Use the listed USDA records and 150–220 g cored Granny Smith with skin. Multiply each per-100-g nutrient by edible grams divided by 100, then sum components. Alternatives are separate scenarios. The range describes the disclosed scenarios, not a confidence interval or official brand nutrition.
