A group of studies presented yesterday at the annual meeting of the American Association for Cancer Research have added to the evidence that diet can be crucial to health. In particular, two studies focused on the cancer-preventive powers of broccoli sprouts.
Prevents Stomach Cancer
A team from Japan found that a diet rich in broccoli sprouts reduced Helicobacteri pylori infection. H. pylori is a cause of gastritis, and it is believed to be an important factor in stomach cancer.
Sulforaphane
The scientists were investigating the anti-cancer properties of sulforaphane, a chemical derived from broccoli sprouts. It acts as an antioxidant, and may destroy the H. pylori bacteria.
In another study on sulforaphane, performed by a researcher from Johns Hopkins University, broccoli sprout extract was applied to the skin of hairless mice, where it was found counteract the carcinogenic response caused by exposure to ultraviolet light.
Half the Tumors
By the end of the study, 100 percent of the mice who had not been treated with the extract developed cancerous skin tumors. Only half that amount developed tumors among the treated mice, however, and those that did developed only half as many tumors.
