(NBC News Channel) -- New research has found that the amount of processed meat consumed by Americans has remained unchanged in the past 18 years.
A new report by the World Health Organization says that eating processed meats increases the likelihood of contracting bowel cancer.
A quarter are also eating more unprocessed red meat than the recommended amount, and less than 15% are eating enough fish.
However, people are also eating more chicken, and less beef.
Previous research has linked the consumption of processed meat to an increased risk of obesity, diabetes, some cancers and heart disease.
The top five consumed processed meats were: lunch meat, sausage, hot dogs, ham, and bacon.
