Original sentence: 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 N-nitroso compounds, compounds that combine with DNA, and alter it so that it is more likely to undergo harmful changes or mutations that increase the likelihood of cancer
