Biological characteristics

Broccoli, also known as cauliflower, broccoli and green cauliflower, is a variety of Brassica in Cruciferae with green flower heads as its products. Originated in Italy along the Mediterranean coast of Europe, it was introduced to China at the end of 19th century.

The morphology and growth habits of broccoli are basically similar to those of cauliflower, but they are strong in growth, heat resistance and cold resistance.

The plant is tall, and after growing more than 2 leaves, the flower stems are pulled out, and the top of the plant is densely clustered with spherical clustered buds, which are turquoise, so it is also called broccoli. The color of leaves is blue-green, gradually turning into dark blue-green, and wax powder increases. The petiole is long and narrow. There are two kinds of leaf shapes: broad leaf and long leaf.

Nutritional value

Among all kinds of vegetables, you may find it difficult to compare which one has the highest nutritional value. However, a recent study in Japan concluded that the average nutritional value and disease prevention function of broccoli far exceeded other vegetables, ranking first.

The nutrients in broccoli are not only high in content, but also comprehensive, mainly including protein, carbohydrates, fats, minerals, vitamin C and carotene. In addition, the mineral composition of broccoli is more comprehensive than other vegetables, and the contents of calcium, phosphorus, iron, potassium, zinc and manganese are very rich, which is much higher than that of cabbage flowers belonging to Cruciferae.

broccoli

many people think that tomatoes, peppers and other vegetables are the most abundant in vitamin C. in fact, the vitamin C content of broccoli is higher than all of them, and it is also significantly higher than other ordinary vegetables. Moreover, there are many kinds of vitamins in broccoli, especially folic acid, which is an important reason why its nutritional value is higher than that of ordinary vegetables.

Rich vitamin K

Vitamin K in broccoli can maintain the toughness of blood vessels and is not easy to rupture. Some people's skin will turn black and blue once they get a little collision and injury, which is because of the lack of vitamin K in their bodies. The best way to supplement is to eat more broccoli.

vitamin c messenger

the content of vitamin c in cauliflower is extremely high, which is not only beneficial to human growth and development, but more importantly, it can improve human immune function, promote liver detoxification, enhance human physique, increase disease resistance and improve human immune function.

high content of vitamin c has a strong scavenging effect on free radicals, especially on the formation of carcinogen-ammonium nitrite.

Especially in the prevention and treatment of gastric cancer and breast cancer, the research shows that the level of selenium in human serum decreases obviously when suffering from gastric cancer, and the concentration of vitamin C in gastric juice is also significantly lower than that of normal people. Cauliflower can not only supplement a certain amount of selenium and vitamin C, but also supply abundant carotene, which can prevent the formation of precancerous cells and inhibit the growth of cancer.

Enzymes

Studies show that an enzyme extracted from cauliflower can prevent cancer, and this substance is called radish seed element, which can improve the activity of carcinogen detoxification enzyme;

Selenium

Broccoli contains a lot of "miracle element"-selenium, which was selected as one of the top ten healthy foods by Time magazine. Selenium has the functions of anti-cancer, anti-aging, enhancing immunity and promoting children's growth and development, and also helps to prevent adult diseases such as hypertension and heart disease.

dithiothiophenol thioketone

Broccoli also contains dithiothiophenol thioketone, which can reduce the enzymes that form melanin and prevent the formation of pigmentation spots on the skin. Regular consumption can smooth and stimulate appetite and have a good whitening effect on the skin.

Flavonoids

Flavonoids contained in cauliflower can reduce the occurrence of cardiovascular diseases.

sulforaphane

Studies show that sulforaphane, a substance contained in broccoli, has a strong anti-cancer effect, especially for breast cancer, rectal cancer and gastric cancer. Scientists have extracted this substance from broccoli for the prevention and adjuvant treatment of cancer.

A variety of indole derivatives

According to American nutritionists, there are many indole derivatives in broccoli, which can reduce the estrogen level in human body and prevent the occurrence of breast cancer.

ascorbic acid

Broccoli is also rich in ascorbic acid, which can enhance the detoxification ability of the liver and improve the immunity of the body.

Antioxidant

Broccoli contains antioxidant isothiocyanide, which can protect eyes from ultraviolet rays in the sun.

glucosinolates

glucosinolates are only found in broccoli in large quantities, which can help break down fat in human body and prevent them from blocking arteries. It is believed that glucosinolates may have certain effects on preventing heart disease and some cancers.

acetylcholine

The study found that people have the strongest memory when they are highly excited. Acetylcholine in the brain is the key substance that can stimulate the excitement of brain cells. But with age, acetylcholine in the brain will decrease. Lack of acetylcholine will not only cause memory loss and mental retardation, but also lead to dementia in severe cases. British scientists have suggested that taking acetylcholine supplements is one of the effective ways to improve memory. Broccoli, cauliflower, cabbage and other cruciferous vegetables all contain acetylcholine, which can promote memory.

Broccoli also contains unique folic acid, amino acids and other precious nutrients.
