Citando:
"A new study from the World Cancer Research Fund (WCRF) found an increased risk of stomach cancer for people drinking three or more alcoholic drinks a day (equivalent to more than 45g of alcohol per day).
Eating the equivalent of 50g per day of processed meat - two rashers of bacon - was also linked to stomach cancer, while being overweight or obese also increased the risk.
(...) There was also some evidence that eating citrus fruit could decrease the risk."
