Intake of broccoli may overturn the damage caused by diabetes to heart blood vessels,says a new study----The researchers believe that the key behind the effect is a compound found in the vegitables,called Sufforaphane.
It encourages production of enZymes,which protects the blood vessls,and reduction in high level of molecules,which causes significant cell damages.
Brassica vegitables such as broccoli have previously been linked to a lower risk of heart attacks and strokes.Peoples with diabetes are upto five times more likely to develop cardiovascular disease such as heart attacks and strokes,both are linked to damaged blood vessels.
The Warwick team,whose work is reported in the journal diabetes,tested the effects of sulforaphane on blood vessel cell damaged by high glucose levels(hyperglycaemia) ,which are associated with diabetes.They recorded 73percent reduction of molecules in the body called Reactive Oxygen Species(ROS) . Hyperglycaemia can cause levels of ROS to increase three-fold and such high levels can damage human cells.
The researchers also found that sulforaphane activated a protien in the body called nrf2,which protects cells and tissues from damage by activating protective antioxidant and detoxifying enZymes.
"Theirs study sugests that compounds such as sulforaphane from broccoli may help counter processes linked to the developing of Vascular disease in diabetes.It will be important to test if eating diet rich in brassica vegitables has health benefits for diabetic patients ,They expect that it will,"BBC quoted the studys lead researcher Proffesor Paul Thornally,as saying.
