Too much beer, hot dogs may up colon cancer risk
Eating hot dogs, bacon and other processed meat regularly or drinking more than two alcoholic drinks daily may increase the risk of colorectal cancer, a study has warned.
Other factors found to increase colorectal cancer include eating high amounts of red meat (above 500 grammes a week), such as beef or pork; and being overweight or obese, researchers said.
The report by the American Institute for Cancer Research (AICR) and the World Cancer Research Fund (WCRF) also found that whole grains, such as brown rice or whole-wheat bread, reduces colorectal cancer risk.
There was strong evidence that physical activity protects against colon cancer, researchers said.
“Colorectal cancer is one of the most common cancers, yet this report demonstrates there is a lot people can do to dramatically lower their risk,” said Edward L Giovannucci, professor at Harvard TH Chan School of Public Health. “The findings from this comprehensive report are robust and clear: Diet and lifestyle have a major role in colorectal cancer,” said Giovannucci.
The report evaluated the scientific research worldwide on how diet, weight and physical activity affect colorectal cancer risk.
It analysed 99 studies, including data on 29 million people, of whom over a quarter of a million were diagnosed with colorectal cancer.
The report concluded that eating three servings (90 grams) of whole grains daily reduces the risk of colorectal cancer by 17 per cent.
