Numerous studies have linked a high intake of red meat or processed meats to colon cancer. KRON 4 Morning News Weekend anchor, Marty Gonzalez, has me explain why eating animal protein and fat are to blame.
Bile is to Blame
- Bile assists with digestion by breaking down fats. Think of bile as “Mother Nature’s degreaser”. This greenish yellow secretion is made and released by the liver, then concentrated and stored in the gallbladder until fat enters your small intestine.
- Bile acids stimulate the growth of bacteria, which convert the primary bile acids into secondary bile acids.
- Bile acids, particularly secondary bile acids, have long been suspected as being cancer-causing.
- Eating more fat means more fat and bile acids in the colon.
High Saturated Fats in the Diet
- A high intake of saturated fat is associated with high levels of bile, which is usually evident in colon cancer patients.
- High saturated fats + high levels of bile are factors that produce colorectal cancer tumors.
Meat Sources High in Saturated Fat
- Meat – e.g., fatty cuts of beef, pork, lamb
- Processed / deli meats – salami, sausages, chicken skin
- Lard – pig fat
