Lettuce : Diet Nutrition
Lettuce is exceptionally low in calories and contains over 90% water. However, dark lettuce leaves are rich in folate and contain useful amounts of beta-carotene as well as vitamin C, potassium and certain phyto-chemicals (coumarins, flavonoids and lactucin) that act as a mild sedative, especially when eaten with bread.
