A recent study has raised concerns about the potential health risks of consuming large amounts of poultry, particularly chicken. While poultry has long been considered a healthier protein source compared to red meat, this new research suggests that eating more than 300 grams (10.5 ounces) of poultry per week may be linked to a 27% increased risk of all-cause mortality and a higher risk of gastrointestinal (GI) cancers.
The study, conducted in southern Italy, contradicts previous findings and calls for a reevaluation of poultry’s role in a healthy diet. Experts emphasize the need for further research to understand the underlying factors and mechanisms, urging moderation and mindful dietary choices until more definitive conclusions can be drawn.

Unexpected Findings Challenge Nutritional Guidelines
Conducted in Southern Italy, the study evaluated dietary patterns in 4,869 middle-aged adults from Castellana Grotte and Putignano (Apulia). Participants self-reported their intake of red and white meat. The data revealed that individuals consuming more than 300 grams (approximately 10.5 ounces) of poultry weekly had a 27% higher risk of all-cause mortality compared to those consuming 100 grams (3.5 ounces) or less.
Moreover, the risk of developing gastrointestinal cancers increased by 2.3% overall, and 2.6% among men, in the higher poultry consumption group.
These results appear in the peer-reviewed journal Nutrients and stand in stark contrast to current dietary frameworks like the Mediterranean diet, which includes poultry as a core component of healthy eating.
Experts Urge Caution and Further Research
Given poultry’s longstanding reputation as a lean, heart-healthy protein, the study has caught the attention of nutrition and oncology experts, many of whom recommend a cautious interpretation.
“Possibly for the first time, white meat consumption needs to be considered a potential risk factor for gastrointestinal cancer,” said Dr. Nilesh Vora, Medical Director of the MemorialCare Todd Cancer Institute in Long Beach, California, who was not involved in the study.
Similarly, Dr. Anton Bilchik, a surgical oncologist and Chief of Medicine at Providence Saint John’s Cancer Institute in Santa Monica, called the findings “alarming,” noting that the Mediterranean diet has consistently been associated with lower risks of cardiovascular disease and cancer.
“This study needs to be looked at in much more detail,” Dr. Bilchik emphasized.
Potential Gaps in the Research
Several limitations of the study have been identified. Notably, it did not account for physical activity, cooking methods, or the sources of poultry consumed, all of which can significantly influence health outcomes. The researchers also didn’t track whether the poultry was processed, an important distinction since processed meats are known to carry higher health risks.
Michelle Routhenstein, MS, RD, a cardiology dietitian, raised concerns about unaccounted variables.
“It doesn’t establish causality,” she said. “Further research is needed to confirm these results and understand the mechanisms involved before revising dietary guidelines.”
How Poultry Is Prepared Matters
One hypothesis is that cooking methods may play a role. High-heat techniques like grilling or frying can produce harmful compounds such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), both linked to increased cancer risk.
Additionally, the use of hormones, antibiotics, or pesticide exposure in poultry farming could also influence health outcomes, though these variables were not controlled for in the study.
“We also need to explore how other proteins, like fish, are prepared. Similar risks may apply,” Dr. Bilchik added.
What Does This Mean for Your Diet?
Despite the study’s findings, experts are not recommending a complete elimination of poultry from the diet. Instead, they advocate for a more nuanced approach:
- Limit intake to approximately 200 grams (7 ounces) per week of lean, unprocessed poultry.
- Avoid processed poultry products like deli meats and chicken hot dogs.
- Opt for healthier cooking methods such as baking, steaming, or roasting.
Be mindful of what you pair with poultry—a balanced diet rich in vegetables, whole grains, and fiber may help mitigate potential risks.
Frequently Asked Questions
What does the study suggest about chicken consumption?
The study suggests that consuming more than 300 grams (about 10.5 ounces) of poultry per week may be associated with a 27% increased risk of all-cause mortality and a 2.3% higher risk of gastrointestinal cancers, specifically in men, compared to those who consume less than 100 grams per week.
Why is this study surprising?
This study is surprising because poultry, particularly chicken, has long been considered a healthier protein option than red meat and is a staple in many healthy eating plans, such as the Mediterranean diet. The results challenge the current nutritional guidelines.
Was the study conducted on a global scale?
No, the study was conducted in Southern Italy, where 4,869 middle-aged adults from Castellana Grotte and Putignano self-reported their poultry and red meat consumption. It’s important to note that these findings are specific to this population and may not apply universally.
Did the study account for other factors that may influence health?
No, the study did not account for factors such as physical activity levels, the source of the poultry consumed, cooking methods, or whether the poultry was processed. These factors could significantly influence the health risks associated with poultry consumption.
Should I stop eating chicken based on this study?
Experts advise caution rather than drastic changes. Moderation is key. Limiting poultry intake to 200 grams (7 ounces) per week and choosing healthier cooking methods (such as baking, steaming, or roasting) can help reduce potential risks.
Does this study apply to all types of poultry?
The study considered various forms of poultry, including chicken, turkey, duck, geese, and game birds like quail and pheasant. However, the risks may vary depending on factors like cooking methods and whether the poultry is processed.
How does this study compare to previous research?
Previous studies generally support poultry as a healthier protein choice compared to red and processed meats. This study, however, is the first to suggest a potential link between frequent poultry consumption and an increased risk of certain health issues, particularly gastrointestinal cancers.
Conclusion
While this new study raises important questions about the potential risks associated with frequent poultry consumption—particularly in relation to all-cause mortality and gastrointestinal cancers—it does not offer definitive answers. The findings challenge longstanding beliefs that poultry is a universally healthier alternative to red meat, especially when consumed in large quantities.
However, experts caution against making drastic dietary changes based on a single observational study. The research lacks critical context, such as physical activity, cooking methods, and the quality or source of the poultry consumed. As such, more comprehensive, controlled studies are needed to confirm these associations and explore the underlying mechanisms.
