The Nutritional Power of the Feijoa
Feijoas, also known as pineapple guavas, are an excellent source of vitamin C and other essential nutrients, making them a true superfruit. Originating in South America and cultivated widely in New Zealand, this fruit offers a sweet, aromatic flavor that tastes like a mix of guava, pineapple, and quince. Beyond their taste, feijoas pack a significant nutritional punch, particularly concerning their vitamin C content, which is vital for overall health.
Feijoa's High Vitamin C Content
Numerous studies have confirmed that feijoas are a great source of vitamin C. The vitamin C content can vary depending on the growing conditions, cultivar, and whether the peel is included. For instance, an Australian study found that some feijoa cultivars can contain as much as 63 mg of vitamin C per 100 grams of fresh weight, while other data suggests around 32.9 mg per 100g. What is most notable is that the edible skin of the feijoa contains a higher concentration of vitamin C than the flesh. This makes eating the whole fruit, or utilizing the peel in recipes, an excellent way to maximize your intake of this key vitamin.
How Feijoa Vitamin C Benefits Your Body
The vitamin C in feijoas provides a host of health benefits, playing multiple critical roles within the body:
- Immune System Support: Vitamin C is a well-known immunity booster that aids in the production of immune cells, helping the body fight off infections. Regular consumption of feijoas during the colder months can help protect against common illnesses.
- Skin Health: As a powerful antioxidant, vitamin C is crucial for collagen synthesis, which is the protein responsible for skin elasticity and strength. It helps protect skin cells from UV damage and fights signs of aging by combating free radicals.
- Wound Healing: The role of vitamin C in collagen production also makes it vital for the rapid healing of cuts and scrapes.
- Antioxidant Defense: The vitamin C, alongside other compounds like flavonoids and polyphenols, provides strong antioxidant capacity that protects cells from oxidative stress and free radical damage.
- Iron Absorption: It aids in the absorption of iron from plant-based foods, which is particularly beneficial for those following a vegetarian or vegan diet.
Maximizing Vitamin C Intake from Feijoas
To get the most out of your feijoas, consider these tips:
- Eat the Peel: The highest concentration of vitamin C is in the fruit's edible skin. While it has a slightly more bitter flavor, blending it into smoothies or using it in baked goods can be an effective way to consume it.
- Fresh is Best: Vitamin C content can degrade over time, so eating feijoas fresh and in season is ideal for peak nutritional value.
- Store Properly: Studies show that vitamin C concentration can increase slightly after a period of storage, so proper refrigeration is key to preserving freshness.
- Pair with Iron-Rich Foods: Combining feijoa with plant-based iron sources, such as spinach in a salad, can enhance iron absorption.
Feijoa vs. Other Vitamin C-Rich Fruits
Feijoas hold their own when compared to other popular vitamin C sources. Their vitamin C levels are higher than those found in fruits like mangoes and tangerines, and similar to or slightly lower than oranges, guavas, and papayas. The exact amounts can differ based on fruit variety, ripeness, and location of growth. The table below provides a general comparison to highlight where the feijoa stands among other common fruits.
| Fruit | Approximate Vitamin C (mg per 100g) | Notes |
|---|---|---|
| Feijoa | ~33-63 mg | Includes high concentration in the edible peel |
| Orange | ~53 mg | A traditional go-to for vitamin C |
| Kiwifruit | ~64 mg | Extremely high vitamin C content |
| Guava | ~228 mg | One of the highest vitamin C fruits |
| Mango | ~28 mg | Slightly lower than feijoa flesh |
| Tangerine | ~26 mg | Lower than feijoa |
