Bowel cancer warning - the food you should AVOID to reduce colorectal cancer

Experts have pinpointed how people can reduce their risk of bowel cancer.

A major new report by the American Institute for Cancer Research has found eating wholegrains daily, such as brown rice or whole wheat bread can lower the risk.

But there are a number of thing people can do to reduce the risk of bowel cancer.

Experts have also found eating high amounts of red meat - above 500 grams - of beef or pork can increase bowel cancer risk.

This also includes processed meats, so hot dogs, bacon, salami, corned beef and beef jerky are best avoided, experts claim.

Red meat - lamb, beef and pork - is darker in colour than chicken or turkey, for example, because it has higher levels of proteins which bind to oxygen, haemoglobin and myoglobin in blood and muscle.

The World Health Organisation has previously said processed meat does cause cancer.

It can also be carcinogenic if it is cooked at high temperature - for example on a barbecue.


"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, lead author of the report and professor of nutrition and epidemiology at the 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."

Professor Giovannucci said: "Many of the ways to help prevent colorectal cancer are important for overall healt

“Factors such as maintaining a lean body weight, proper exercise, limiting red and processed meat and eating more whole grains and fibre would lower risk substantially.

“Moreover, limiting alcohol to at most two drinks per day and avoidance or cessation of smoking also lower risk."

The report also looked into other links between diet and colorectal cancer which were not as clear as the link to processed meat.

Experts said there was limited evidence that risk increases with low intake of both non starchy vegetables and fruit.

Food containing vitamin C - such as oranges, strawberries and spinach are all high in vitamin C.
