Can eating 50 grams of meat a day increase your risk of dying by 18%?

The viral headline is misleading. No food directly "feeds" cancer, and eating a single serving of meat does not automatically cause cancer or increase your risk of death overnight. However, regular consumption of processed meat has been linked to a higher risk of colorectal cancer, while diets high in red meat may also contribute to a modest increase in risk when consumed frequently over many years.

Does Meat Feed Cancer?

One of the most common myths online is that "cancer feeds on meat."

The truth is more complicated.

Cancer cells require nutrients—including glucose, amino acids, and fats—just like healthy cells do. They do not specifically feed on meat.

Instead, scientists study whether long-term dietary patterns influence the risk of developing certain cancers.

The strongest evidence concerns processed meat, not all meat.

What Is Processed Meat?

Processed meat refers to meat that has been preserved by:

• Smoking

• Curing

• Salting

• Fermenting

• Adding preservatives

Common examples include:

• Bacon

• Sausages

• Hot dogs

• Salami

• Pepperoni

• Ham

• Corned beef

These foods often contain:

• Sodium nitrite

• High levels of sodium

• Preservatives

• Saturated fat

Why Do Experts Recommend Limiting Processed Meat?

The World Health Organization (WHO) has classified processed meat as a Group 1 carcinogen, meaning there is strong evidence that regular consumption increases the risk of colorectal cancer.

This classification refers to the strength of the evidence, not the size of the risk.

A commonly cited estimate is that eating about 50 grams of processed meat daily is associated with an approximately 18% relative increase in the risk of colorectal cancer compared with eating none.

Important to Understand

An 18% relative increase does not mean that 18 out of every 100 people will develop cancer.

For example: If someone's lifetime risk were about 5%, an 18% relative increase would raise that risk to roughly 5.9%—still a relatively small absolute increase, but meaningful at a population level.

What About Fresh Red Meat?

Fresh, unprocessed red meat includes:

• Beef

• Pork

• Lamb

• Goat

• Veal

Research suggests that frequent, high consumption of red meat may modestly increase the risk of colorectal cancer, although the evidence is weaker than for processed meat.

Eating moderate portions as part of a balanced diet is generally considered acceptable for most healthy adults.

Healthier Protein Choices

Instead of eliminating meat completely, experts recommend varying your protein sources.

Good options include:

• ✔ Fish

• ✔ Skinless poultry

• ✔ Beans

• ✔ Lentils

• ✔ Chickpeas

• ✔ Tofu

• ✔ Eggs

• ✔ Low-fat dairy

A varied diet provides important nutrients while reducing reliance on processed meats.

Other Factors That Affect Cancer Risk

Diet is only one piece of the puzzle.

Other important risk factors include:

• Smoking

• Heavy alcohol use

• Obesity

• Physical inactivity

• Family history

• Certain infections

• Excessive sun exposure (for skin cancer)

• Age

These factors often have a much larger impact on overall cancer risk than one specific food.

Simple Ways to Lower Your Cancer Risk

Doctors recommend focusing on long-term healthy habits:

• ✔ Eat more fruits and vegetables.

• ✔ Choose whole grains.

• ✔ Limit processed meat.

• ✔ If you eat red meat, enjoy moderate portions.

• ✔ Stay physically active.

• ✔ Maintain a healthy weight.

• ✔ Avoid smoking.

• ✔ Limit alcohol.

• ✔ Participate in recommended cancer screening programs.

Should You Stop Eating Meat Completely?

For most people, no.

Lean, unprocessed meat can provide valuable nutrients such as:

• Protein

• Iron

• Zinc

• Vitamin B12

The goal isn't necessarily to eliminate meat, but to:

• Eat smaller portions.

• Choose lean cuts.

• Limit processed meats.

• Balance meals with vegetables, legumes, and whole grains.

The Bottom Line

The viral claim that "this type of meat feeds cancer" is misleading. While high consumption of processed meats and red meat is linked to an increased risk of certain cancers, eating meat in moderation as part of a balanced, healthy diet remains safe and nutritious for most people.
