Broccoli is a popular vegetable known for its many health benefits. One of its key components is sulforaphane, which has been shown to help regulate blood sugar levels and is considered one of the most potent anti-cancer substances known. However, the benefits of sulforaphane are destroyed within minutes of cooking, requiring broccoli to be "damaged" before it can be absorbed. A recent study conducted by Chinese researchers suggests that cutting broccoli into pieces and allowing it to rest for 90 minutes before cooking can increase sulforaphane levels by 2.8 times.
The Study
Researchers from Zhejiang University purchased broccoli from a local market and divided them into three groups: some were left as is, some were cooked immediately for four minutes, and the rest were left to rest for 90 minutes before also being quickly cooked over high heat.
Why Waiting is Important
While it may seem impractical to wait 90 minutes before cooking broccoli, the researchers suggest that even 30 minutes of resting can be beneficial. It is important to cut broccoli into pieces because sulforaphane can only be absorbed if the vegetable is damaged. However, for those who do not have the time to wait, researchers from the University of Reading found that adding mustard powder to cooked broccoli significantly increased sulforaphane levels.
Other Benefits of Broccoli
In addition to its sulforaphane content, broccoli has been shown to help prevent everything from arthritis to heart disease, and even keep your gut healthy. Studies have found that mice fed a diet of broccoli were better able to tolerate digestive issues.
