Do We Have To Give Up Bacon?

TL;DR

Processed meat consumption is linked to an 18% increase in the risk of developing colorectal cancer.

Transcript

Last week, the International Agency for Research on Cancer released a report establishing a link between eating processed meat, which I love, and cancer. Specifically, colorectal cancer. And you might have heard people saying things like, “Eating meat is as dangerous as smoking cigarettes!” and “the World Health Organization has declared a war on d... Read More

Key Insights

• 🍖 The IARC report links processed meat consumption to an 18% increased risk of colorectal cancer.
• 🍖 The classification system used by the IARC categorizes processed meat as a definite carcinogen (Group 1) and red meat as a probable carcinogen (Group 2A).
• 🙅 Chemicals formed during the processing and cooking of meat, specifically N-nitroso compounds (NOCs), can cause DNA mutations and increase cancer risk.
• 💁 The IARC report does not offer specific health advice but aims to inform individuals about the potential risks associated with consuming processed meat.
• 👂 The study emphasizes that processed meat is not as dangerous as smoking cigarettes or other substances on the Group 1 list.
• ♋ The 18% increase in risk does not imply an 18% chance of developing cancer; it refers to the increase in the starting cancer risk.

Questions & Answers

Q: Is eating processed meat as dangerous as smoking cigarettes?

No, while processed meat has been classified as Group 1, along with carcinogens like cigarettes, it is not equally dangerous. The categories define the strength of evidence, not the level of danger.

Q: How does processed meat cause cancer?

Certain chemicals are formed during the processing and cooking of meat, which can break down and form N-nitroso compounds (NOCs). These compounds can cause DNA mutations that can lead to cancer.

Q: Is it advisable to stop eating processed meat entirely?

While consuming excessive amounts of processed meat may increase the risk of cancer, the report does not provide specific health recommendations. It is ultimately up to individuals to weigh the risks and make their own decisions.

Q: Can you explain the difference between the starting cancer risk and the 18% increase?

The 18% increase in risk applies to your starting cancer risk. For example, if the average risk is 5%, eating 50 grams of processed meat per day increases the risk to 5.9%.

Summary & Key Takeaways

• The International Agency for Research on Cancer (IARC) established a connection between eating processed meat and colorectal cancer.

• Processed meat, when consumed in quantities of 50 grams per day, can increase the risk of developing colorectal cancer by 18%.

• Red meat was categorized as "probably carcinogenic," with insufficient evidence to establish a definite link to cancer.
