Among the best foods recommended by the World Health Organization, cabbage and purple cabbage are listed, and they are also well-known "anti-cancer" vegetables - they contain glucose isothiocyanate, which is released during chewing, metabolized by the body, and becomes isothiocyanate. Subsequently, isothiocyanate produces indole and thiosomes throughout the metabolic process.

In vitro experiments, it was found that indole and thiosaccharides have a certain inhibitory effect on some cancer cells.

In terms of anti-cancer effect, the difference between the two is not large, and the obvious difference is in the antioxidant content.

Compared with white ordinary cabbage, purple cabbage is rich in anthocyanins, which is a powerful antioxidant that can protect the body from free radical damage, has an anti-aging effect, and can also enhance the elasticity of blood vessels.

Note: Both purple cabbage and cabbage can be eaten raw, with a crispy texture and more nutrients retained.

In recent years, baby cabbage has entered the public life, because the price is higher, some people think that its nutritional value is better than Chinese cabbage, is this really the case?

Chinese cabbage and baby cabbage belong to the cruciferous family. However, baby cabbage is not a cabbage that does not grow up, it is a new variety of vegetables imported from abroad, and it has begun to be favored in China in recent years.

In contrast, baby cabbage tastes sweeter and tenderer, and in terms of nutritional value, in addition to the vitamin C and potassium content is higher than that of Chinese cabbage, the other is not more prominent than Chinese cabbage, but the price is much more expensive, do not have to be deliberately purchased because of nutrition.

The market uses Chinese cabbage cores as baby cabbage, pay attention when purchasing: its roots are thinner than cabbage hearts, the leaves are more tightly wrapped, the color is light green, and the cabbage core is yellow-green.

Because leeks are slightly more complex in the production process, the price is more expensive, but its nutritional value is slightly inferior to that of leeks.

The content of minerals and vitamins in leeks is higher than that of leeks, of which the content of calcium, iron, phosphorus, vitamin A and carotene is 3-4 times that of leeks; In the theory of Chinese medicine, spring leeks can nourish the liver, and autumn and winter leeks can strengthen the stomach.
