The exact number of calories in 1 longan can vary slightly based on its size and how it is prepared, such as fresh versus dried.

Quick Summary

A single fresh longan fruit typically contains around 2 calories, making it a very low-calorie snack. The nutritional breakdown primarily consists of carbohydrates and a small amount of vitamin C, with negligible fat and protein. Fresh longans differ from dried or canned versions, which have higher caloric density due to sugar content and processing.

Fresh Longan Calorie Count Explained

When we ask how many calories are in 1 longan, the answer is remarkably low. A single fresh, raw longan fruit, often weighing around 3.2 grams (g) without the inedible shell and seed, contains approximately 2 calories. This calorie count is derived primarily from its carbohydrate content, with virtually no fat and very little protein. Longan is also composed of about 83% water, contributing to its low-calorie density. Its small size and high water content make it an excellent choice for a hydrating, low-calorie snack. This makes it a popular choice for people on low-calorie diets or those looking for a healthier alternative to sugary snacks.

Nutritional Composition of a Single Fresh Longan

While the calorie count is small, the overall nutritional profile is still noteworthy. A single longan provides trace amounts of vitamins and minerals. For instance, it contains about 3 milligrams (mg) of vitamin C, contributing to your daily intake. It also provides minimal amounts of potassium, phosphorus, and magnesium, all of which are essential for various bodily functions. However, its main nutritional contribution is its sweet flavor without a significant caloric load.

How Processing Affects Longan Calories

The way longan is prepared and consumed significantly alters its caloric and nutritional values. Fresh longan is the lowest in calories, but dried and canned versions are much more calorie-dense.

  • Dried Longan: When longans are dried, the water is removed, concentrating the natural sugars and, consequently, the calories. A serving of 20 dried longans, for example, can contain around 97 calories. This makes dried longan a much more calorie-dense food than its fresh counterpart, which is an important consideration for those tracking their calorie intake.
  • Canned Longan: Longans preserved in syrup are another popular form. The addition of sugar syrup dramatically increases the calorie count. Draining the syrup can reduce some of the added sugar, but the overall caloric value will still be higher than fresh fruit. Canned varieties are often a convenient option but do not offer the same low-calorie benefits as fresh longans.

Comparing Longan to Other Fruits

Longan's low-calorie density becomes clear when compared to other popular fruits. Here is a simple comparison table illustrating the difference in caloric and carbohydrate content per 100g serving.

Fruit (per 100g) Calories Carbohydrates (g) Key Advantage
Longan (Fresh) ~60 kcal ~15.1 g Very low-calorie, high vitamin C content
Lychee (Fresh) ~66 kcal ~16.5 g Similar nutrient profile, slightly higher calorie count
Grapes (Fresh) ~69 kcal ~18.1 g Higher sugar content, good source of vitamin K
Apples (Fresh) ~52 kcal ~13.8 g Very low-calorie, good source of fiber
Mango (Fresh) ~60 kcal ~15 g Rich in vitamins A and C, similar calorie count

From the table, it's evident that longan is on the lower end of the calorie spectrum among tropical fruits, comparable to mango and lychee, and even slightly lower than grapes. This makes it a smart choice for a healthy, balanced diet.

Conclusion: The Bottom Line on Longan Calories

The short answer to "how many calories are in 1 longan?" is a very small number, around 2 calories. This minimal caloric impact is associated with the consumption of fresh longans. However, the calorie count can increase significantly when the fruit is dried or canned in syrup due to the concentration of sugars or the addition of sweeteners. For those seeking a delicious, low-calorie, and hydrating snack, fresh longan is an excellent option. Its high water content and small amounts of essential vitamins and minerals make it a health-conscious choice, especially when compared to processed fruits or sugary treats.

It is important to remember that while longans are healthy, portion control is still key, especially with the more calorie-dense dried versions. For more detailed nutritional information on other fruits, a reliable source like the USDA database is always recommended.
