Apple Calories 100g

How many calories are in 100g of apple?

A 100g serving of raw apple contains 52 kilocalories based on USDA FoodData Central and EFSA nutrition tables.
This value represents the gross energy of fresh, edible apple pulp excluding skin or core. Calorific value derives from naturally occurring sugars, primarily fructose and glucose. Apples include simple carbohydrates like sucrose and complex molecules like dietary fiber.

Calorie values per 100g were confirmed by independent labs using bomb calorimetry and Atwater general factors. Nutrient composition includes 13.8g carbohydrates, 0.3g proteins, 0.2g fats, and 2.4g dietary fiber. These values were validated in peer-reviewed analyses such as the Journal of Food Composition and Analysis. Average sugar content of 10g explains the primary energy source, especially from soluble carbohydrates.

Energy contribution per 100g is similar in different apple varieties, such as Gala, Fuji, and Red Delicious, when raw and unprocessed. Variations may occur in dehydrated apples or juice, but fresh apple pulp maintains ~52 kcal. Energy varies under different ripeness levels or storage conditions. Values remain valid if apple is fresh and not processed.

What is the calorie content of 100 grams of apple?

Calorie content of 100 grams of raw apple is 52 kcal, verified by USDA SR Legacy and EFSA databases.
This refers to the metabolizable energy in 100 grams of edible portion, excluding seeds and skin. Calories come from intrinsic fruit sugars, which are rapidly digestible. The caloric composition is based on macronutrient ratios present in standard apple cultivars.

Macronutrient analysis confirms energy yield from 13.8g total carbohydrates, including 10g sugars, 0.3g protein, and 0.2g fat per 100g. Peer-reviewed food composition studies like the EuroFIR project document consistency of these nutritional outputs. Water content, accounting for 85%, dilutes calorie density in apple compared to dried fruit.

Calorie content shows stability across apple batches unless altered by dehydration, fermentation, or cooking. In raw state, fresh apple maintains stable calorie density. The 52 kcal figure holds under standard laboratory conditions and is applicable unless fruit undergoes moisture loss or thermal processing.

How many kcal in 100 grams of apple?

Raw apple provides 52 kcal per 100 grams of edible fruit pulp, based on laboratory-calculated macronutrient energy conversions.
This value remains consistent across global food data repositories, including USDA and FAO food energy metrics. Energy content is computed using Atwater coefficients applied to carbohydrates, proteins, and fats present in the fruit matrix.

Each 100g portion includes 13.8g carbohydrates, with 10g mono- and disaccharides like fructose and sucrose. Analytical reports from food labs and agriculture databases confirm energy contributions from sugars. Fat and protein contribute minimally, adding ~2% of total energy yield.

Caloric value applies to fresh, raw apples of standard moisture content, such as 85g water per 100g fruit. Changes in calorie value occur only if drying, baking, or juicing alters sugar or fiber content. Caloric density increases in dried apples or chips due to water loss.
