The Nutritional Profile of a Peru Guava
While the term "Peru guava" may not refer to a single distinct species but rather guavas grown in or associated with Peru, their nutritional value is largely consistent with common guava varieties (Psidium guajava). A standard 100-gram serving of raw guava provides an energy content of around 68 kilocalories (kcal). This is relatively low, making it an excellent snack for those managing their weight. The majority of these calories come from carbohydrates, while the fat content is exceptionally minimal. Beyond its basic energy value, this fruit is a powerhouse of essential vitamins and minerals.
Macronutrient Breakdown
- Carbohydrates: Per 100g, guava contains approximately 14.32 grams of carbohydrates, which primarily consist of natural sugars.
- Dietary Fiber: An impressive 5.4 grams of dietary fiber is found in a 100g serving. This high fiber content is a significant factor in promoting digestive health and can contribute to feelings of fullness.
- Protein: At around 2.55 grams per 100g, guava offers a modest amount of protein for a fruit.
- Fats: The fat content is very low, measuring about 0.95 grams per 100g.
Key Vitamins and Minerals
Guava is particularly celebrated for its high vitamin C content. In fact, a 100g portion can provide over 200% of the daily recommended intake. This makes it a far richer source of vitamin C than many other fruits, including oranges. The fruit also offers other vital nutrients such as potassium, which is important for maintaining healthy blood pressure, and vitamin A, in the form of beta-carotene, for vision and immune function.
Factors Affecting Guava's Calorie Count
It is important to remember that the precise calorie count can be influenced by several factors. These include the fruit's size, ripeness, and specific cultivar. For instance, smaller or less ripe guavas may have a slightly different macronutrient composition than larger, fully matured ones. A single, average-sized fruit, weighing around 55 grams, contains approximately 37 calories. Furthermore, how the guava is consumed can impact the total calorie intake. Processed products like guava jam or juice will have a different and often higher caloric value due to added sugars.
Peru Guava vs. Common Guava: A Nutritional Comparison
While specific Peruvian varieties may exist, the nutritional data for Psidium guajava is generally applicable. A common point of interest is the difference between white-fleshed and pink-fleshed guavas, which are both found in many regions, including Peru. The primary nutritional difference is in their antioxidant and sugar content. Pink-fleshed guavas are typically richer in lycopene, the antioxidant also found in tomatoes and watermelon, giving them their characteristic color.
Comparison of Guava Varieties (per 100g)
| Nutrient | Common Guava | Pink Guava | White Guava |
|---|---|---|---|
| Calories | ~68 kcal | ~54 kcal | ~52 kcal |
| Carbohydrates | 14.32 g | 13 g | 12.4 g |
| Protein | 2.55 g | 1.1 g | 0.9 g |
| Vitamin C | 228 mg | 80.6 mg | 99.2 mg |
| Lycopene | High | Higher | Lower |
Note: Nutritional data can vary slightly depending on the specific source and growing conditions.
