Broccoli has long been considered a healthful vegetable. A new study from the University of Sydney has uncovered another potentially important benefit of broccoli.
One of the chemical compounds found in broccoli may help prevent blood clots that lead to strokes. Stroke is the second leading cause of death worldwide.
What Scientists Discovered
Researchers have long noted broccoli’s role in boosting the body’s resistance to various diseases, including cancer.
Now, the scientists conducted a series of laboratory tests on 23 compounds present in broccoli to determine their tendency to bind with blood platelets. Platelets play a crucial role in sealing wounds and stopping bleeding; however, under certain circumstances, they can form dangerous clots that completely block blood flow. In vital organs like the brain and heart, even a momentary loss of oxygen can cause irreversible damage.
The chemical compound sulforaphane (SFN), commonly found in cruciferous vegetables like broccoli and cauliflower, appears to inhibit blood clotting. This compound has previously attracted medical attention for its potential in cancer prevention and cholesterol reduction.
A thorough analysis of SFN’s effects at the molecular level showed that it can slow platelet aggregation and prevent clot formation under conditions similar to those found in our arteries. This is likely due to its modification of the activity of a protein called PDIA6.
“Broccoli compounds are not only effective in enhancing the action of drugs that dissolve clots after a stroke, but they can also be used as a preventive measure for patients at high risk of stroke,” noted biomedical researcher Xu Liu, the lead author of the study.
The study’s findings make SFN a worthy candidate for further investigation as a means of reducing stroke risk in certain vulnerable groups. This is especially significant since SFN is naturally found in foods like broccoli, which support heart health and protect against various ailments.
SFN could also be used in emergency situations. For instance, it may help treat patients who have suffered a stroke by minimizing the stroke’s impact on the brain. These treatment methods could mitigate the damage caused by clots and ultimately save lives.
Current thrombolytic medications (known as tissue plasminogen activators, or tPA) protect patients against brain damage in only 20 percent of cases. In experiments with mice, combining SFN with tPA raised the protection rate to 60 percent, according to Science Alert.
“It’s remarkable that this natural compound (SFN) does not cause bleeding, a common side effect associated with blood-thinning medications used to treat strokes,” Dr. Xu Liu pointed out.
This research is still in its early stages. The Australian team says the results merit further study in stroke prevention.
This study is particularly important given that approximately 15 million people worldwide suffer strokes each year. About one-third of these cases result in death, while another third lead to disability.
Researchers are pleased to have identified a “huge positive effect” from consuming this popular vegetable: its ability to prevent strokes and aid recovery for those who have experienced one.
The study’s results were published in the journal ACS Central Science.
