About Lettuce and tomato
Lettuce and tomato are staple ingredients commonly used in a variety of cuisines worldwide, particularly in salads, sandwiches, and wraps. Lettuce, originally cultivated in Ancient Egypt, belongs to the Asteraceae family and provides a low-calorie, hydrating base. Tomatoes, believed to have originated in South America, are nutrient-dense fruits rich in antioxidants. Together, they form a nutrient-rich combination. Lettuce is primarily composed of water (up to 95%) and offers small amounts of vitamins A, K, and folate, while tomatoes are an excellent source of vitamin C, potassium, and lycopene, a powerful antioxidant. This pairing is not only refreshing but also helps meet daily hydration and micronutrient needs.
