Poultry, particularly chicken, has long been celebrated as a lean, healthy protein source, often recommended over red meat for its lower saturated fat content. In the United States, chicken reigns supreme, with the average American consuming over 100 pounds annually.
However, recent research casts a shadow over this dietary staple, suggesting that excessive poultry consumption may be linked to serious health risks, including higher mortality rates and gastrointestinal cancers.
The Rise of Poultry in American Diets
Chicken’s popularity in the U.S. has soared over the past six decades, with consumption tripling due to its affordability, versatility, and perceived health benefits.
The Dietary Guidelines for Americans (DGA) recommend 26 ounces of lean meats and poultry per week for a 2,000-calorie diet, with chicken often highlighted as a “noble food” for its high protein and lower fat content compared to red meat.
Yet, emerging evidence challenges the assumption that chicken is universally safe, urging a closer examination of how much is too much.
Key Statistics on Poultry Consumption
- Annual Intake: Americans consume over 100 pounds of chicken per person yearly, far exceeding global averages.
- Dietary Recommendations: The DGA suggests 3.5-ounce servings of poultry one to three times weekly, totaling up to 10.5 ounces.
- Cultural Staple: Chicken’s ease of preparation and availability in supermarkets make it a go-to protein for many households.
Unpacking the Research: Poultry and Health Risks
A pivotal study published in Nutrients on April 17, 2025, conducted by researchers at the National Institute of Gastroenterology in Italy, tracked 4,869 middle-aged adults over 19 years.
The findings revealed a concerning association between high poultry consumption and increased mortality, particularly from gastrointestinal cancers such as colon, liver, pancreatic, stomach, esophageal, and rectal cancers. This research, corroborated by other reports, highlights the need for moderation in poultry intake.
Key Findings from the Italian Study
- Mortality Risk: Individuals consuming over 300 grams (10.5 ounces) of poultry weekly faced a 27% higher risk of death from all causes compared to those eating less than 100 grams (3.5 ounces).
- Gastrointestinal Cancer: Those eating 100–200 grams weekly had a 65% increased risk of death from gastrointestinal cancers, while over 300 grams raised this risk by 127%, with men facing a 161% higher risk.
- Gender Differences: Men consuming over 300 grams weekly were 2.6 times more likely to die from digestive cancers than those eating less, possibly due to hormonal differences like estrogen’s protective effects in women.
Supporting Evidence
Other studies echo these concerns. A 2021 UK Biobank study of 474,985 adults found that higher poultry intake (per 30 grams/day) was associated with increased risks of gastro-oesophageal reflux disease, gastritis, diverticular disease, gallbladder disease, and diabetes, though it lowered the risk of iron deficiency anemia.
Additionally, a 2022 scoping review of 525 articles noted that while poultry is often studied indirectly compared to red meat, its links to cancer, cardiovascular disease, and diabetes warrant further investigation.
Why Poultry Might Pose Risks
The exact mechanisms driving these risks remain unclear, but several factors are hypothesized based on the research:
Cooking Methods
- High-Temperature Cooking: Grilling, barbecuing, or prolonged cooking at high temperatures can produce mutagens—substances that cause genetic mutations potentially linked to cancer.
- Frying Concerns: Fried chicken, high in fat and calories, may contribute to negative health outcomes, unlike baked or steamed preparations.
Industrial Farming Practices
- Chemical Residues: Pesticides in feed, hormones, or medications given to chickens can leave toxic residues in meat, potentially increasing cancer risk.
- Antibiotic Use: Overuse of antibiotics in poultry farming may lead to residues in meat, affecting nutritional quality and increasing oxidative stress, which impacts meat tenderness and consumer health.
- Mycotoxins: Contaminated feed can transfer mycotoxins to poultry meat, altering its color, pH, and nutritional value, posing health risks.
Processing and Preparation
- Lack of Specificity: Studies often fail to distinguish between processed (e.g., deli meats) and unprocessed poultry, complicating risk assessments. Only 1% of observational studies address processed poultry’s impact.
- Industrial Processing: Battery-farmed poultry, common in many regions, may contain higher levels of contaminants compared to organic or free-range options.
Limitations of the Research
While compelling, the studies have notable limitations that temper their conclusions:
- Self-Reported Data: Diets were reported via questionnaires, which may be subject to recall bias.
- Lack of Physical Activity Data: Physical activity, a known factor in mortality risk, was not measured, potentially skewing results.
- Preparation Methods: The absence of data on how poultry was cooked or processed limits the ability to pinpoint specific risk factors.
- Observational Nature: These studies show correlation, not causation, meaning other lifestyle or dietary factors could contribute to the observed risks.
Recommendations for Safer Poultry Consumption
Given the evidence, moderation and mindful preparation are key to enjoying poultry safely. Here are practical steps to reduce potential risks:
Moderation in Intake
- Limit Weekly Consumption: Aim for less than 100–200 grams (3.5–7 ounces) of poultry per week to minimize mortality and cancer risks.
- Balance with Other Proteins: Alternate poultry with fish, legumes, eggs, or plant-based proteins like tofu to diversify nutrient intake.
- Portion Control: Stick to 3.5-ounce servings, one to two times weekly, as suggested by the DGA.
Healthier Preparation Methods
- Avoid High-Heat Cooking: Opt for baking, steaming, or poaching over grilling or frying to reduce mutagen formation.
- Choose Lean Cuts: Select skinless chicken breasts or thighs to lower saturated fat intake.
- Incorporate Vegetables: Pair poultry with fiber-rich vegetables to support digestive health, though this may not fully mitigate risks as seen with red meat.
Choosing Quality Poultry
- Opt for Organic or Free-Range: These options may reduce exposure to pesticides, hormones, and antibiotics, though they cost about $4 more per pound.
- Check Labels: Look for “antibiotic-free” or “humanely raised” certifications to ensure better farming practices.
Broader Dietary Patterns
- Embrace Variety: A balanced diet with whole grains, fruits, vegetables, and lean proteins supports long-term health more effectively than focusing on one food.
- Consider Plant-Based Options: Non-meat proteins like beans or lentils offer similar nutrients without the risks associated with animal-based foods.
Expert Insights and Additional Facts
Nutrition experts emphasize that chicken remains a valuable protein source when consumed thoughtfully. Lauren Manaker, a registered dietitian, notes that chicken provides essential nutrients like B vitamins, iron, and zinc, crucial for energy, immunity, and growth.
Dr. Donald Hensrud from the Mayo Clinic highlights poultry’s lower saturated fat content compared to red meat, making it a better choice for heart health when prepared lean.

Looking Ahead: The Future of Poultry Research
The current studies highlight a critical need for further research to clarify poultry’s health impacts. Future investigations should:
- Examine Processing: Differentiate between unprocessed and processed poultry to isolate specific risks.
- Study Cooking Methods: Quantify the impact of various preparation techniques on health outcomes.
- Include Lifestyle Factors: Account for physical activity, smoking, and other variables to strengthen causal links.
- Explore Global Diets: Compare poultry consumption risks across diverse populations to identify universal versus region-specific trends.
Conclusion
Chicken’s status as a dietary hero is under scrutiny as recent studies link high consumption to increased mortality and gastrointestinal cancer risks.
While poultry offers valuable nutrients, exceeding 300 grams weekly—roughly four 3.5-ounce servings—may pose significant health concerns, particularly for men. Factors like high-heat cooking, industrial farming practices, and chemical residues could contribute to these risks, though more research is needed to establish causation.
For now, moderating intake, choosing healthier preparation methods, and diversifying protein sources are prudent steps to enjoy poultry safely. By balancing chicken with plant-based proteins and maintaining a varied diet, consumers can savor this staple while prioritizing long-term health.
