Romaine Lettuce Benefits: Romaine lettuce is, first and foremost, a low calorie vegetable. It is high in fiber and water content, too, making it a suitable food for individuals looking to manage or lose weight. Romaine lettuce has heart-healthy benefits, too. As it turns out, the fiber in this leaf vegetable binds with bile acids. The latter are primarily made up of cholesterol which the liver makes to aid in the process of storing fats in the body. When you eat romaine lettuce, its fiber binds with bile acids and both get eliminated via the bowels.
