Have researchers found strong links between cruciferous vegetables and cancer risk?

By Christopher Hutton
NO

According to the National Cancer Institute, human studies have typically shown no specific reductions in cancer risk from consuming cruciferous vegetables like broccoli, kale or cabbage. These vegetables contain glucosinolates, which break down into compounds found to inhibit cancer development in rodents. They can of course be part of the kind of fresh, healthy diet thought to reduce overall risk.

Researchers continue to explore whether eating cruciferous vegetables might lower cancer risk in more specific ways. A 2000 Netherlands study found women who consumed more cruciferous vegetables had a lower risk of colon cancer. Other studies have shown links between cruciferous vegetable consumption and lower breast and lung cancer rates in women. A 2014 Chinese study found the consumption of a broccoli beverage lowered levels of the carcinogen benzene.

ABOUT THE CONTRIBUTOR
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
