What is it about processed meats (ground beef, turkey, bacon) that consuming it causes cancer way more often in humans?
In: Biology
Many things.
1) Meat contains no fiber. People who eat a meat heavy diet have a slower transit time (the time it takes for food to travel from mouth to anus). Slower transit time is a risk factor for colorectal cancer.
2) Meat is high in fat. High fat diets are linked with higher cancer rates. Fat triggers the gallbladder to release bile. (Bile helps us break down and absorb fats.) High levels of bile acids are associated with colon cancer.
3) Processed meats contain nitrites. Nitrites are associated with a higher risk of stomach cancer. Processed meats include bacon, ham, sausages, hot dogs, salami and deli meats. Nitrites are added to these meats to prevent bacterial growth.
4) Meat contains arachidonic acid. Arachidonic acid is pro-inflammatory. Higher levels of inflammation in the body are associated with a higher risk of cancer.
