First, the nutritional value of lettuce leaves.
Some nutrition experts have made a detailed nutritional analysis of lettuce, saying that the nutritional content of leaves is higher than that of bamboo shoots. I think there are three main nutrients in vegetables and plants: vitamins and minerals, dietary fiber and carbohydrates. Among them, there will be anthocyanins in the pigment, and dietary fiber, vitamins and minerals constitute the core nutrients of vegetables. Moreover, it has unique characteristics of existence. The nutrition of vegetables is mainly distributed in the epidermis, and the nutrients in the epidermis are relatively concentrated.
Lettuce is no exception. The nutrition of leaves is much higher than that of bamboo shoots. The data show that the content of vitamin C in lettuce is four times more than that in bamboo shoots and six times more than that in carotene. Dietary fiber is more than bamboo shoots, but more than peeled bamboo shoots. Most of these nutrients in bamboo shoots are on the skin, but they are lignified and can't be eaten, so they can only be cut and thrown away. Therefore, the overall nutritional content is lower than that of leaves.
Second, the edible value of lettuce leaves.
First of all, it is manifested in the taste. Two words: delicious. Lettuce leaves are equivalent to many other leafy vegetables, and various methods such as cold salad, stir-frying and soup making are delicious, even if they are eaten raw.
The second performance is outstanding nutritional efficacy, comparable to traditional Chinese medicine. To sum up, there are three main points:
Clearing away heat and toxic materials. According to the theory of traditional Chinese medicine, lettuce is cool and slightly bitter, which conforms to the pharmacological characteristics of clearing heat and detoxifying. In life, lettuce is generally used as an adjuvant treatment for heat toxicity. Relaxation and diuresis. Dietary fiber from lettuce leaves is an important substance needed by human body. At present, mainstream public opinion points the finger at the problems existing in the dietary structure of Chinese residents, because the lack of dietary fiber leads to the high incidence of colon cancer, obesity, coronary heart disease and other diseases. Too fine staple food, less coarse grains, less vegetables and retention of stool will all cause these hazards. Eat leafy vegetables, the stool is smooth, the urine is smooth, and all diseases are not born. Improve metabolism. Especially sugar metabolism, niacin contained in lettuce leaves helps to activate insulin and promote sugar metabolism, which is an ideal vegetable for sugar lovers.
