For instance, studies reveal that isothiocyanate metabolites can be detected in the blood and urine after cooked glucosinolate - containing foods are eaten, although to a lesser extent than their raw glucosinolate - containing counterparts.69 In far messier studies, scientists have taken cooked watercress and simply mixed it with human feces, which converted the glucosinolates to isothiocyanates through
their intrinsic myrosinase activity.
