**4.2 Function**

Several studies revealed that isothiocyanates and their metabolites decrease the risk of developing different types of cancer, such as stomach, breast, liver, esophagus, lung, small intestine, and colon [36, 37]. Isothiocyanates effect *Helicobacter pylori* and reduce the risk of developing gastric cancer. On the other hand, sulforaphane inhibits the growth of multiple strains of bacteria [38] and there is a role in eradication in some cases [39]. People who consume isothiocyanates-rich vegetables have a lower incidence or severity of cardiovascular disease [40].
