About Key lime
Key limes are small, spherical citrus fruits native to Southeast Asia that later gained popularity in the Florida Keys, giving them their name. They are commonly used in Caribbean, Mexican, and Floridian cuisines for their distinctively tart, tangy flavor. Smaller and more aromatic than Persian limes, key limes have a greenish-yellow skin when ripe. Nutritionally, key limes are low in calories (approximately 20 calories per fruit) and high in vitamin C, an essential nutrient that supports immunity and skin health. They also contain small amounts of potassium, magnesium, and folate, as well as beneficial antioxidants.
Health Benefits
- Rich in vitamin C, key limes support immune function and promote healthy skin, aiding collagen synthesis.
- Contain antioxidants like flavonoids, which help protect cells from oxidative damage and reduce inflammation.
- Small amounts of potassium help maintain healthy blood pressure and heart function.
Dietary Considerations
Selection and Storage
Store key limes in a cool, dry place and refrigerate to prolong their freshness for up to two weeks. Keep them whole until ready to use to retain juiciness.
