Sulforaphane is a type of isothiocyanate that has blood-sugar-reducing properties. This plant chemical is produced when broccoli is chopped or chewed due to a reaction between a glucosinolate compound called glucoraphanin and the enzyme myrosinase, both of which are concentrated in broccoli. Studies have shown that Sulforaphane-rich broccoli extract has powerful antidiabetic effects, helping enhance insulin sensitivity and reduce blood sugar and markers of oxidative stress.
