Roman lettuce and lettuce are different in taste, eating method and nutritional value. The important difference between long leaf lettuce and lettuce is that the taste of long leaf lettuce is not as fresh as lettuce. Lettuce tastes crisp and contains a lot of water, but the taste of Roman lettuce is not so good, not as crisp and refreshing as ordinary lettuce. Different ways of eating Roman lettuce can only be made into cold salad. After washing lettuce, tear it into small pieces, and add some seasonings such as edible salt and olive oil to eat it cold. Lettuce can also be mixed cold in a similar way, but lettuce can also be used for cooking, making soup and cooking noodles, while Roman lettuce is only used for cold mixing, not suitable for cooking, stewing and making soup. The content of vitamin C in lettuce with different nutritional values is higher than that in common lettuce, followed by protein and carbohydrates. Lettuce is also rich in vitamin C, and also contains a lot of carotene, dietary fiber and minerals. What is Roman lettuce? Roman lettuce is a kind of lettuce, similar to China's head lettuce, but not as refreshing as head lettuce in texture. Roman lettuce can be eaten just like bulbous lettuce, and it can be washed and mixed directly. The growth of organic lettuce does not contain any herbicides, fumigants, artificial pesticides or fungicides. The use of organic fertilizer is strictly in accordance with organic certification standards, which is impossible in ordinary farming.
