Understanding the Two Varieties of Paw Paw
Before discussing the calorie content, it's essential to clarify that the term 'paw paw' can refer to two very different fruits, a point of frequent confusion for consumers. The first is the tropical fruit, Carica papaya, widely known as papaya, particularly in the United States, but commonly called paw paw in Australia and other regions. This fruit has a reddish-orange flesh and is a staple in many tropical diets. The second is the American pawpaw, Asimina triloba, a native North American fruit with a flavour reminiscent of banana and mango. Its creamy, custard-like texture is distinctly different from the tropical variety. This article focuses on the caloric differences between these two distinct fruits.
Calorie Count and Nutritional Breakdown for Tropical Paw Paw (Carica papaya)
For the tropical fruit, often labeled papaya in US markets but sold as paw paw elsewhere, the calorie count is relatively low. This makes it a popular choice for weight-conscious individuals and those seeking a low-calorie snack packed with nutrients.
A standard 100-gram serving of raw, tropical paw paw fruit contains approximately 43 calories. Here is a more detailed look at its macronutrient composition per 100g:
- Carbohydrates: 11g, including 1.7g of dietary fiber and 7.8g of sugars.
- Protein: 0.47g.
- Fat: 0.26g.
It is also exceptionally rich in Vitamin C, providing about 68% of the Daily Value per 100g, making it a fantastic immune-boosting fruit. Its rich fiber and water content help promote a feeling of fullness, which can aid in weight loss.
Calorie Count and Nutritional Breakdown for American Pawpaw (Asimina triloba)
The American pawpaw, with its richer, denser flesh, contains a significantly higher calorie count than its tropical counterpart. This is due to its higher concentration of fats and proteins.
According to studies by Kentucky State University's Pawpaw Research Project, a 100-gram serving of ripe American pawpaw contains about 80 calories. The nutritional breakdown per 100g is as follows:
- Carbohydrates: 18.8g.
- Dietary Fiber: 2.6g.
- Protein: 1.2g.
- Fat: 1.2g.
This variety is particularly noted for its higher mineral content, including substantial amounts of magnesium, iron, copper, and manganese.

Health Benefits Beyond Calories
Regardless of the variety, paw paw fruits offer a wealth of health benefits that go beyond their calorie count. These benefits are derived from their rich content of vitamins, minerals, and antioxidants.
Benefits of Tropical Paw Paw (Papaya)
- Digestive Aid: Contains the enzyme papain, which aids in protein digestion and can help reduce digestive discomfort.
- Immune Support: Extremely high in Vitamin C, which is crucial for immune function.
- Heart Health: The high antioxidant content, including lycopene, may reduce the risk of heart disease.
- Skin Health: Vitamin C helps in collagen production, while antioxidants like lycopene protect against UV damage.
Benefits of American Pawpaw
- High Mineral Content: A single serving provides more than 100% of the Daily Value for manganese and significant amounts of iron and magnesium.
- All Essential Amino Acids: The protein content includes all essential amino acids, making it a more complete protein source for a fruit.
- Rich in Antioxidants: Contains compounds like acetogenin, which are being studied for their potential anti-cancer properties.
Incorporating Paw Paw into Your Diet
For both varieties, paw paw can be a nutritious and delicious addition to your diet. Given the substantial difference in calorie density, understanding the type you have is important, especially for those with specific dietary goals.
- Low-Calorie Option (Tropical Paw Paw/Papaya): This fruit is a fantastic choice for those aiming for weight loss or managing blood sugar levels. Its high water and fiber content provide a satisfying snack that is low in calories. It can be eaten fresh, added to fruit salads, or blended into smoothies. Its low glycemic index also helps maintain stable energy levels.
- Nutrient-Dense Option (American Pawpaw): Because of its richer profile, the American pawpaw serves as a more filling and calorically dense fruit, ideal for a more substantial snack or dessert. It can be pureed into custards, frozen for later use, or used in baked goods.
Conclusion
To conclude, understanding how many calories does paw paw contain requires knowing which variety you are dealing with. The tropical Carica papaya (often called paw paw in Australia) is a low-calorie, high-vitamin C fruit ideal for lighter snacks. In contrast, the American pawpaw (Asimina triloba) is a more calorie-dense, nutrient-rich fruit with a distinct custard-like flavour and high mineral content. Both offer unique nutritional benefits, but their different caloric profiles mean they serve different roles in a balanced diet. For anyone planning meals or tracking macros, verifying the type of paw paw is the first and most important step.
