broccoli is a star vegetable, but how to eat it healthily? According to a new study by Zhejiang University published in the American Journal of agricultural and food chemistry, broccoli is the healthiest way to eat broccoli, which is chopped, dried and then cooked for 90 minutes.

and

researchers cut broccoli into 2 mm thick pieces, one cooked immediately, the other placed for 90 minutes before cooking. The results showed that the content of sulforaphane in broccoli increased by 2.8 times after 90 minutes. Some scientists believe that 30 minutes after cutting broccoli is enough, and further research is needed.

researchers point out that cutting broccoli is to activate the myrosinase, which is used to protect plants from herbivores during the evolution of broccoli and other plants. It can enhance the absorption of sulforaphane in broccoli. A number of early studies have found that sulforaphane in broccoli can stabilize blood glucose, prevent cancer, prevent arthritis, heart disease and digestive tract diseases.
