Lettuce first. Lettuce is usually produced once a year or twice a year, so it is not always possible to eat lettuce. Moreover, the stems of lettuce are very straight, and they are all plant by plant. Secondly, the lower leaves of lettuce are also very big. Let's look at lettuce again. Lettuce is also a vegetable once or twice a year. Rooted, slightly bitter or not. As far as these are concerned, there is not much difference between them, but it should be noted that lettuce is definitely not bitter. The contents of vitamins and fat are less than those of oil wheat vegetables, and the carotene content of oil wheat vegetables is about 1.4 times that of lettuce.
Lettuce leaves are rich in vitamins, in addition, they are also rich in calcium, protein and fat, among which vitamin B is the highest. Although most of the water in lettuce also contains vitamins, compared with lettuce leaves, it is not as good as lettuce leaves in vitamins and fat. The content of carotene is about 1.4 times that of lettuce.
