Broccoli is rich in nutrients, including protein, carbohydrates, fats, minerals, vitamin C and carotene. According to the analysis, every 100g of fresh broccoli contains 3.5g ~ 4.5g of protein, which is three times that of broccoli and four times that of tomato. In addition, the mineral composition of broccoli is more comprehensive than other vegetables, and the content of calcium, phosphorus, iron, potassium, zinc and manganese is very rich, which is much higher than that of cruciferous cabbage. Broccoli is also rich in ascorbic acid, which can enhance the detoxification ability of the liver and improve the immunity of the body. A certain amount of flavonoids can regulate and prevent hypertension and heart disease. At the same time, broccoli is a high-fiber vegetable, which can effectively reduce the absorption of glucose in the gastrointestinal tract, thus lowering blood sugar and effectively controlling the condition of diabetes.
