May protect against certain cancers

Leeks include a variety of anti-cancer chemicals. For example, kaempferol in leeks has been associated with a decreased incidence of chronic illnesses, including cancer. According to animal studies, kaempferol may combat cancer by lowering inflammation, destroying cancer cells, and stopping them from spreading. Leeks are also high in allicin, a sulfur molecule known to have anti-cancer qualities.

Ramps grown on selenium-rich soil may help cut cancer risks in rats, according to animal research. Furthermore, human studies show that individuals who consume alliums on a regular basis, including leeks, may have a 46 percent reduced risk of stomach cancer than those who do not. Likewise, large consumption of alliums may be associated with a decreased risk of colon cancer. Keep in mind that further study is required before drawing firm conclusions.
