Eating four or more chicken meals weekly doubles the risk of death from digestive cancers, according to a two-decade Italian study that has troubling implications for American dinner tables.
At a Glance
- Consuming over 300g of chicken weekly doubles the risk of dying from digestive cancers like bowel and stomach cancer
- The Italian study followed 5,000 middle-aged adults for two decades
- Heavy chicken consumption was linked to a 27% increased risk of death from any cause
- Men face significantly higher risks than women from equivalent chicken consumption
- Cooking methods, additives, and hormones in poultry production may contribute to cancer risk
The Chicken Cancer Connection
What many Americans consider a healthy protein choice may carry hidden risks. A major Italian study spanning 20 years has found that regularly eating chicken could significantly increase mortality risk from gastrointestinal cancers. The research followed nearly 5,000 participants, primarily in their 50s, and documented concerning patterns connecting poultry consumption with cancer deaths. Those eating more than 300 grams of chicken weekly – approximately four portions – faced double the risk of dying from digestive cancers compared to those who consumed less than one portion weekly.
The findings challenge conventional wisdom about poultry as a healthier alternative to red meat. While previous dietary guidelines have encouraged Americans to favor chicken over beef, this research suggests that excessive poultry consumption carries its own set of risks. The study found that eating more than four portions of chicken weekly was associated with a 27% increased risk of death from any cause, with digestive cancers showing the strongest correlation.

Are you worried about cancer? Do you want to increase your body’s natural defenses against this disease? While conventional treatments exist, exploring natural alternatives is equally important. That’s…

Men at Greater Risk
Perhaps most troubling for male consumers is the gender disparity revealed in the research. Men appear significantly more vulnerable to the cancer-causing effects of chicken consumption than women. The study showed men were 2.6 times more likely to die from digestive cancers linked to poultry consumption compared to women eating the same amount. This striking difference suggests biological factors may amplify the cancer risk for men.
Researchers speculate that hormonal differences, particularly estrogen levels, may offer women some protection against cancer-causing agents in chicken. This theory aligns with other cancer research that has documented differences in cancer susceptibility between men and women. The findings suggest middle-aged men who regularly consume chicken might need to be particularly vigilant about their intake levels.
What Makes Chicken Risky?
Several factors may contribute to the increased cancer risk associated with poultry. High-temperature cooking methods can create heterocyclic amines and polycyclic aromatic hydrocarbons – compounds classified as “probably carcinogenic to humans” by the World Health Organization. Modern industrial chicken production may also play a role, with concerns about feed composition, growth hormones, and medications used in commercial poultry operations.
The study didn’t differentiate between various chicken cuts, preparation methods, or whether the poultry was processed or organic. These limitations represent what researchers themselves called a “potentially serious limitation” in assessing the exact mechanisms behind the increased cancer risk. The failure to account for cooking methods and whether participants consumed chicken skin, which can absorb more carcinogenic compounds, leaves important questions unanswered.
Practical Recommendations
Despite the concerning findings, researchers aren’t suggesting Americans eliminate chicken entirely from their diets. Rather, they recommend a more balanced approach to protein consumption, with greater dietary diversity. Alternating chicken with other protein sources, particularly fish, may help mitigate cancer risks while maintaining adequate nutrition. The researchers also emphasized the importance of preparation methods, suggesting lower-temperature cooking and avoiding charring or burning chicken.
For Americans accustomed to frequent chicken consumption, these findings merit serious consideration. While chicken remains an important source of protein, vitamin B12, and other nutrients, exceeding 300 grams weekly (roughly the equivalent of two chicken breasts) appears to cross a threshold where cancer risks increase substantially. As with many dietary guidelines, moderation and balance appear to be the prudent approach to incorporating poultry into a healthy diet.
