Granny Smith Apple Calories
How many calories are in a Granny Smith apple?
A medium Granny Smith apple contains 80 kilocalories.This value corresponds to a raw, unpeeled Granny Smith apple weighing approximately 200 grams, as measured by the USDA National Nutrient Database. The caloric value derives from 22 grams of carbohydrates, including 17 grams of sugars and 4 grams of dietary fiber. Caloric values vary depending on apple size and water content.
Calorie measurements in apples follow the Atwater system. This system assigns kilocalories per gram based on carbohydrate, protein, and fat composition. Granny Smith apples contain negligible fat and protein, so carbohydrates provide nearly all energy. The energy density remains low due to the high water ratio, typically 85% of total weight.
The USDA FoodData Central and peer-reviewed data from The Journal of Food Composition and Analysis report consistent values for Granny Smith apples. Their figures show minor fluctuation of ±5 kcal between samples. Variants with different growing conditions or larger diameters exceed 90 kilocalories, depending on sugar concentration and weight.
What is the calorie count of a Granny Smith apple?
The calorie count of a Granny Smith apple is 80 kcal per medium-sized fruit.A medium Granny Smith apple weighs 200 grams and delivers 80 kilocalories based on macronutrient composition. Most of these calories originate from natural fruit sugars such as fructose and glucose, recorded at 17 grams per 200-gram apple. The values are validated by USDA and EFSA datasets.
Each fruit contributes energy through carbohydrate metabolism. The apple has nearly no fat or protein, which means energy is sourced from carbohydrate fermentation in digestion. The apple’s glycemic load remains low, despite its sugar content, due to fiber concentration and acid profile.
Is a Granny Smith apple high in calories?
A Granny Smith apple is not high in calories.The average calorie count for a medium apple is 80 kcal, which classifies it as a low-calorie fruit. High-calorie classification typically begins at 120 kilocalories per 100 grams, which Granny Smith apples do not meet. The U.S. FDA dietary guidelines recognize foods with <40 kcal per 100 grams as low-calorie, and Granny Smith meets that in relative density.
The low-calorie classification arises from the apple’s high water content and moderate sugar ratio. Water makes up more than 85% of a Granny Smith apple’s weight. Its acidic taste correlates with lower sugar levels, reducing overall caloric load per serving. The absence of fat and protein lowers total energy output compared to bananas or mangos.
Are Granny Smith apples low in calories?
Granny Smith apples are low in calories.Each medium apple contains only 80 kcal, placing it within the “low-calorie” category based on USDA and EFSA classification. The low energy yield stems from the fruit’s low sugar content and high water percentage. Per 100 grams, the calorie content is roughly 40 kcal, meeting low-calorie thresholds in food labeling systems.
Low-calorie classification includes fruits with low energy density. Granny Smith apples meet that by offering high fiber content and low total digestible carbohydrates. Their sugar content is lower than Red Delicious and Pink Lady apples. Clinical diet comparisons showed Granny Smith apples provide 15% fewer calories than sweeter apple varieties.
How many calories are in a medium Granny Smith apple?
A medium Granny Smith apple contains 80 calories. This value refers to an average-sized apple weighing approximately 182 grams, according to USDA FoodData Central. The value includes the peel and reflects raw apple content without additional ingredients.Caloric content is influenced by water-to-fiber ratio.
Medium Granny Smith apples have 85% water and 2.4g fiber per 100g. The low sugar density contributes to lower caloric values compared to sweeter apples such as Fuji or Honeycrisp. USDA data shows Fuji apples of similar weight reach 95 calories.
Energy values in apples result from glucose, fructose, and sorbitol. Medium Granny Smith apples have 17g carbohydrates, including 13g sugar. These nutrients affect glycemic response. Research from Harvard Medical School confirms apples with higher acidity and lower sugar yield lower glycemic index values.
How many calories are in 100 grams of Granny Smith apple?
100 grams of Granny Smith apple contains 52 calories. This is the standardized value measured by weight using USDA’s nutrient profile. The weight unit excludes variability from size and shape.Energy content per 100g derives from 13.8g carbohydrates, 0.3g fat, and 0.2g protein. Most calories come from natural sugars.
Granny Smith apples have lower fructose than Red Delicious, reducing total calories. USDA data shows Red Delicious at 59 kcal per 100g, making Granny Smith lower in calorie density.
Multiple databases confirm similar values. NutritionData, MyFitnessPal, and Cronometer list 51–53 calories per 100g. These platforms base results on lab-verified samples. Values align across geographic regions and harvest seasons if sugar accumulation remains constant.
How many calories are in a large Granny Smith apple?
A large Granny Smith apple contains 115 calories. This value applies to apples weighing around 260 grams. USDA FoodData Central provides the reference calorie range based on empirical measurements.
Calorie increase in large apples is proportional to weight. A 260g apple has roughly 36g sugar and 22g net carbohydrates. Water content still dominates, keeping energy density low per gram. Despite larger size, caloric load remains lower than bananas or pears of equal weight.
Data compiled by the Journal of Food Composition and Analysis validates large-size variation. Their study sampled 50 large Granny Smith apples with average values between 110–120 kcal. This confirms the 115 kcal benchmark used by most diet-tracking applications.
How many calories are in a peeled Granny Smith apple?
A peeled Granny Smith apple contains 68 calories. This applies to a medium apple of 182g after skin removal. Caloric difference results from fiber loss, since skin contributes 2–3g dietary fiber.Peeling reduces total nutrients.
Apple skins carry phenolic compounds like quercetin, which influence metabolism and digestion. Without skin, apples lose about 3g fiber and 4 kcal. Journal of Agricultural and Food Chemistry notes that 20% of antioxidants are lost with peel removal.
Most dieticians measure peeled values by subtracting peel weight and fiber calories. The USDA reports the peel weighs 30g and provides 12 kcal. Thus, peeled apple has 15% fewer calories, fiber, and phytochemicals compared to unpeeled samples.
How many calories are in a Granny Smith apple without the skin?
A Granny Smith apple without the skin contains 68 calories. This value reflects the same energy data as a peeled apple, assuming a medium size of 182g. Removing skin lowers total calories due to fiber and antioxidant loss.
Apple skin contains polyphenols, dietary fiber, and micronutrients. Removing it reduces nutrient density. USDA profiles show fiber drops from 4g to 1g, and calories from 80 to 68. Energy reduction comes mostly from decreased insoluble fiber and lower satiety impact.
Research published in the British Journal of Nutrition confirms skin removal lowers glycemic control potential. Studies in overweight individuals showed peeled apples raised glucose faster than whole apples. This supports lower-calorie count and lower nutritional efficiency.
