Massive cancer study of 17.5 million people found strong evidence that processed meat increases risk of stomach cancer.
In its April 2016 report, the World Cancer Research Fund (WCRF) has found strong evidence that links the consumption of processed meat to stomach cancer. The report—an update on WCRF’s 2007 findings—reviewed 89 global studies that included approximately 17.5 million people and 77,000 cases of stomach cancer. In addition to meat, frequent consumption of alcohol, salt-preserved foods, and obesity were also found to increase stomach cancer risk. These findings follow the 2015 World Health Organization’s classification of processed meat as a carcinogen. In contrast, vegan diets have been found to slash risks of severe illnesses such as heart disease, prostate cancer, and diabetes.
