Further meta-analyses found similar results on the incidence of stomach cancer by consuming allium vegetables including garlic.
A 2014 meta-analysis of observational epidemiological studies found that garlic consumption was associated with a lower risk of stomach cancer in Korean people.
A 2016 meta-analysis found no effect of garlic on colorectal cancer.
A 2014 meta-analysis found garlic supplements or allium vegetables to have no effect on colorectal cancers.
