In a study to examine how effective different varieties of onion are at killing cancer cells, a team of scientists at the University of Guelphhas found that not all of them are created equal

The study involved placing colon cancer cells in direct contact with quercetin extracted from the five different onion varieties.

“We investigated the bioactive properties of five Ontario grown varieties of onion and assessed their capacity to exert cytostatic/cytotoxic effects on a relevant human colorectal cancer cell line,” the researchers said.

“Extracts created from five different Ontario grown onion varieties are effective in inducing cytotoxic, cytostatic, and anti-migratory activities in a human colorectal adenocarcinoma cell line,” they explained.

“These extracts significantly induced apoptosis, reduced the rate of proliferation, and slowed the migration of cancer cells into an exclusion zone. Importantly, these effects were at least comparable, and often stronger, than those of the commercially available pure flavonoid compound
