How did the saying “cabbage is better than all kinds of vegetables” come about? What is the nutritional value of cabbage? Can you eat cabbage with black spots? Can I eat cabbage for 21 days to detoxify my body?
Next, all for you to answer.
The best thing about cabbage is that it’s not as good as cabbage.
According to “Chinese vegetable cultivation” (second edition), cabbage vegetable cultivation can be divided into Chinese cabbage, common cabbage, wu collapsed cabbage, cabbage shoots, shoots and purple cabbage shoots. In life, people say cabbage generally refers to Chinese cabbage or yellow sprouts white (scientific name of nodular cabbage), and small cabbage or green cabbage (scientific name of non-nodular cabbage).
Cabbage is varied, tender and nutritious, with its high content of micronutrients and some phytochemicals (e.g. flavonoids, carotenoids, etc.).
Cabbage can be combined with many ingredients to create a wide variety of dishes, such as stir-fried cabbage, cabbage stewed with tofu, spicy cabbage, etc. It can also be made into pickles (such as sauerkraut) and stored as appetizers on the table.
Cabbage is more resistant to storage, in the era of underdeveloped planting technology and inconvenient transportation, it is difficult to grow vegetables in the north of China in winter, cabbage may become the only vegetable they can put on the table in winter. Moreover, compared to other vegetables, the price of cabbage is relatively low, fluctuations are small. Therefore, there is a folk saying that “a hundred vegetables are not as good as cabbage”.
Cabbage is relatively rich in dietary fiber, and relevant studies have shown that dietary fiber is related to the prevention or treatment of some chronic non-communicable diseases, such as gastrointestinal diseases, diabetes, cardiovascular diseases and so on. In addition, the dietary guidelines for China’s residents suggest that we should eat vegetables at every meal and ensure that we eat 300g to 500g of vegetables every day.
Cabbage grows “black spots” can still eat?
People in the buy cabbage will find that some of the cabbage leaf veins and petioles will appear some similar to sesame black or dark brown spots, this is a physiological disease of cabbage, called “sesame-like spot disease”.
This physiological disease is mainly caused by the inherent genetics of cabbage varieties, external cultivation measures (such as excessive fertilizer) and environmental conditions under the joint action. It also occurs in other cruciferous leafy vegetables such as rape and kale.
However, this physiological disease mainly affects the commercialization of cabbage, such as the appearance of the quality of the decline in the impact of the purchase rate, export, etc., basically does not jeopardize our health, you can eat normally. It should be noted that, if it is formed by the corruption and deterioration of the larger pieces of black spots, it should be avoided.
It should be reminded that the application of too much nitrogen fertilizer may cause excessive nitrate content in vegetables, and nitrate will be converted into nitrite (NO2-) by microbial action in the body, the amount of large may be harmful to human health. Therefore, people in the planting of cabbage, do not use excessive nitrogen fertilizer, which is not only conducive to reducing the emergence of sesquiterpene blotch disease, but also to ensure food safety.
Eating cabbage for 21 days in a row can “detoxify”?
Usually, the term “detoxification” is used to refer to the process of eliminating harmful substances from our bodies, but this is just a “marketing” concept that is easy to understand, not a scientific concept. Our body exchanges substances with the outside world every day, and it is a natural process that metabolized metabolites (so-called “toxins”) are eliminated from the body through the end of the digestive system and the urinary system.
“Toxins” will not be eliminated just because you eat certain foods, but only that certain food components are conducive to the work of some of the organs of our body, such as dietary fiber has the effect of promoting intestinal peristalsis. Therefore, eating cabbage for 21 days and the so-called “detoxification” is not necessarily related.
In addition, some beneficial components in many foods, do not have to be obsessed with a single food, otherwise it is easy to cause nutritional imbalance, which in the long run is likely to induce some diseases, such as metabolic disorder syndrome.
How to store cabbage properly in winter?
The main component of cabbage is water, want to long-term preservation can also maintain the quality of the texture of the tender, the first thing to do is to avoid light, low temperature preservation, through the effect of the activity of plant cell respiration-related enzymes to inhibit the respiration of plant cells, thereby reducing the metabolism of cabbage.
In addition, the conditions can also be isolated by the way of oxygen, to reduce cellular respiration of cabbage, reduce organic matter consumption, to prolong the freshness of cabbage time.
