Quote:Cancer
Recent studies show that red meat could pose an increase in cancer risk. Some studies have linked consumption of large amounts of red meat with breast cancer,[9] colorectal cancer,[10][11] stomach cancer,[12] lymphoma,[13] bladder cancer[14] and prostate cancer.[14][15] Furthermore, there is evidence that consumption of beef, pork, lamb, and goat from domesticated animals is a cause of colorectal cancer.[16] Professor Sheila Bingham of the Dunn Human Nutrition Unit attributes this to the haemoglobin and myoglobin molecules which are found in red meat. She suggests these molecules, when ingested trigger a process called nitrosation in the gut which leads to the formation of carcinogens.[17]
Eating cooked red meat may increase the likelihood of cancer because carcinogenic compounds called heterocyclic amines are created during the cooking process. Heterocyclic amines may not explain why red meat is more harmful than other meat, however, as these compounds are also found in poultry and fish, which have not been linked to an increased cancer risk.[18]
A 2009 study by the National Cancer Institute revealed a correlation between the consumption of red meat and increased mortality from cancer and cardiovascular diseases.[19] This study has been criticized for using an improperly validated food frequency questionnaire,[20] which has been shown to have low levels of accuracy [21][22]
[edit]Cardiovascular diseases
Red meat consumption is associated with cardiovascular diseases, possibly because of its high content of saturated fat.[14]
A 1999 study funded by the National Cattlemen's Beef Association, an advocacy group for beef producers, involved 191 persons with high cholesterol on diets where at least 80% of the meat intake came from either lean red meat in one group, or lean white meat in another. The results of this study showed nearly identical cholesterol, and triglyceride levels in both groups. This study suggests that lean red meat may play a role in a low-fat diet for persons with high cholesterol.[23][24]
