Can lettuce be eaten directly?

The best way to know if a dish is delicious is to eat it directly. For me, lettuce is certainly a delicious vegetable. Lettuce, also known as leaf lettuce, is the general name of all leaf lettuce and belongs to the genus Lettuce in Compositae. The lettuce we usually eat is actually a variety of lettuce, which is basically a patent of China people. Looking around the world, lettuce has various shapes, including green lettuce and purple lettuce according to the color of leaves; If we classify according to the shape of leaves, I'm afraid there will be hundreds (considering the different varieties), but we usually eat lettuce and loose leaf lettuce. Ball lettuce is generally fried, and loose leaf lettuce is mostly used to make salads in the west.

The most suitable season for eating lettuce is spring, autumn and winter when the temperature is low, because the weather is hot and the climate is dry, and it is easy to eat bitterness. Lettuce is a good source of vitamin K. Except for light lettuce, most of them are rich in folic acid, which is a good choice for daily vitamin supplementation. In the west, lettuce is most commonly used to make salads or eaten raw in hamburgers and sandwiches.

Fresh lettuce eaten raw can really ensure that vitamins are not easy to be destroyed, but it is easy to cause another problem-microbial infection. Generally, the water source for irrigating lettuce is polluted by animal manure, and harmful Escherichia coli remains on the leaves and enters the human body.

Of course, we in China still prefer to eat cooked lettuce. In Daoxiao Noodles or Lamian Noodles, lettuce is cooked quickly, and a few green lettuce leaves are cooked, which suddenly increases our appetite. In addition, fresh lettuce leaves are also a good dish for soup. Lettuce is very easy to cook, and it is very delicious to mix it cold after boiling water or stir-fry it directly with a few cloves of garlic in a hot pot.
