Lettuce (Lactuca sativa) is a vegetable with an inner core (or heart) and layers of leaves growing out. Depending on variety the leaves can vary in color from white, to green, to red or purple.
Health Benefits of Lettuce:
Increased Protection from Bacterial and Viral Infections
Increased Immune Function
Reduced Cancer Risk
Reduced Risk of Colon Cancer
Protection Against Heart Disease
DNA Repair and Protection
Alleviation of Cardiovascular Disease
Alleviation of Hypertension (High Blood Pressure)
Prevention of Epileptic Seizures
Prevention of Alopecia (Spot Baldness)
Lettuce is known to help soothe a cough or other bronchial problems. Lettuce is also used as a mild sedative or narcotic. Used externally, lettuce extracts are found in sunburn lotions and can be used to treat other inflammation. *Some of these health benefits are due to the nutrients highly

How to choose Lettuce: Look for vibrant crisp leaves and avoid any lettuce that looks wilted, flimsy, and weak.
Climate and origin: Depending on variety lettuce can grow in almost any climate and at any time of year. It is not known where lettuce originated, but it was first cultivated by the ancient Egyptians.
Taste: Taste depends on variety, but in general, lettuce has a bitter and bland taste. Leaves towards the heart of the lettuce tend to be more tender than tougher outer leaves.
Miscellaneous information: Lettuce was viewed in Roman culture as a symbol of high morality and temperance, and was known for its medicinal properties. Lettuce was so important to the Romans that the emperor Augustus had a statue made in its honor.
