The researchers found in 12 case-control studies, that a high intake of garlic compared to a low, the chance of getting stomach cancer significantly with 40% [95% CI = 0.47-. 76] reduced.
The researchers found in 13 case-control studies, that a high intake of onions compared to a low, the chance of getting stomach cancer significantly with 45% [95% CI = 0.41-0.73] reduced.
