Romaine Lettuce
Romaine Lettuce is a crisp, elongated leafy green commonly used in salads, sandwiches and Mediterranean cuisines; the inner tender leaves are often sold as 'hearts' for ease of use. It is very low in calories and is notable for being a rich source of vitamin A (871 µg RAe per 100g), which supports vision and immune function. Romaine is also high in water and fiber, very low in fat, and contains antioxidant carotenoids that contribute to its protective, nutrient-dense profile.
