ROMAINE LETTUCE 🥬

What It Is?

Romaine lettuce (Lactuca sativa) is a leafy green vegetable commonly used in salads and sandwiches. It belongs to the daisy family (Asteraceae) and has been cultivated for thousands of years, dating back to ancient Mediterranean civilizations. Romaine lettuce forms long, upright heads with crisp leaves and a slightly bitter flavor.

Romaine lettuce provides vitamin A (from beta-carotene), vitamin K, folate, and vitamin C, along with several antioxidant plant compounds. It also contains carotenoids such as lutein and zeaxanthin, which are associated with eye health and protection against oxidative stress.

Romaine lettuce is best known for supporting eye health, heart health, immune function, hydration, and antioxidant protection.
