Specific botanical groups of fruit and vegetable consumption and liver cancer and chronic liver disease mortality: a prospective cohort study

Keen consumption of lettuce, carrots, legumes, sweet potatoes, and cruciferous vegetables may guard against the onset of liver cancer and mortality from the disease.

This study compared the liver cancer development and mortality risk between consumers and non-consumers of specific fruits and vegetables. Researchers tracked the eating habits, rate of occurrence, and mortality from liver cancer among 485,403 middle-aged and elderly men and women recruited from the National Institutes of Health-American Association of Retired Persons Diet and Health Study. 

Researchers observed that eating generous portions of lettuce, carrots, legumes, sweet potatoes, and cruciferous vegetables drove down the risk of developing and dying from liver cancer. The findings of this study showed that liver cancer is less likely to occur among high consumers of vegetables, such as lettuce, carrots, legumes, sweet potatoes, and cruciferous vegetables.
