Broccoli is a nutritious vegetable, providing many vitamins, minerals and antioxidants. However, the processing method can directly affect the nutritional value absorbed by the body, especially the compound sulforaphane.
According to Ms. Stephani Johnson, nutritionist (RDN, DCN), visiting professor at the Department of Clinical Nutrition Services and Prevention, Rutgers School of Health Professions, in the United States, cooking for too long can significantly reduce important nutrients in broccoli, including sulforaphane, a compound that plays a role in protecting cells and reducing oxidative stress.
Cooking for a long time can lose nutrients
Cooking at high temperatures or for a long time can inactivate the enzyme myrosinase. This is an enzyme necessary to convert the natural compounds in broccoli into sulforaphane. When this enzyme is reduced in activity, the amount of antioxidants produced also decreases.
Therefore, strong cooking methods such as boiling for a long time or cooking thoroughly can cause broccoli to lose a part of its nutritional value.
Cutting finely before cooking helps increase benefits
One of the simplest ways to retain many nutrients is to shred broccoli before processing. This helps activate the enzyme myrosinase, supporting the formation of sulforaphane.
For better results, broccoli should be chopped and left for about 90 minutes before cooking. This time helps natural reactions take place before the temperature reduces enzyme activity.
Quick stir-frying is a suitable method
Compared to other cooking methods, stir-frying quickly in a short time is considered a suitable method to retain many nutrients. This method helps soften vegetables while still limiting the loss of antioxidants.
In addition, broccoli can also be eaten raw if it suits your taste. This helps preserve enzymes and beneficial compounds.
The role of sulforaphane in health
Sulforaphane is a natural compound found in cruciferous vegetables such as broccoli, Brussels sprouts or kale. This substance has antioxidant and anti-inflammatory properties, helping to protect cells from damage.
In addition, sulforaphane also helps the body eliminate harmful substances, contributing to protecting cardiovascular health and supporting liver function.
Broccoli is still good no matter how you cook it
Although the processing method may affect some nutrients, broccoli is still a healthy food. This vegetable provides fiber, vitamins and many important biological compounds.
Notes
To optimize nutritional value, broccoli should be chopped before cooking and priority fast cooking methods such as stir-frying. However, the most important thing is still to maintain the habit of eating vegetables regularly to support long-term health.
