There are so many different varieties of lettuce, with similar but different nutritional profiles and applications. No salad is complete without a colourful array of leafy greens. The health benefits of lettuce include heart health, neural tube defect prevention and healthy bones.
Romaine lettuce is one of the more nutritious varieties. An average serving of 2 cups of Romaine lettuce contains over half the Daily Value for Vitamin A, 45% of the Daily value for Vitamin C and nearly 150% of the Daily value for Vitamin K. It is also a good source of B vitamins, especially folate, and the minerals potassium, iron and phosphorous. Lettuce is exceptionally low in calories and high in water, which means a couple of leaves on a sandwich wont give you much nutrition, but when a good portion is added to a salad, the nutritional value increases considerably. Darker varieties of greens, which are not technically lettuce, like rocket and watercress are particularly nutritious. The health benefits of lettuce include heart health, prevention of neural tube defects and healthy bones.

Because lettuce is rich in folate, they have applications in preventing neural tube defects. Eating folate rich foods pre-pregnancy and during pregnancy can help the fetal spinal column to develop normally.
Lettuce for Healthy Bones
One of the health benefits of lettuce is related to its high vitamin K content, which makes it useful in protecting against osteoporosis by preventing the activation of cells called osteoclasts that cause bone loss.
