Eating chicken every day for protein intake? New study suggests SHOCKING consequences

It might be one of the most unanimous statements coming from the foodies and fitness enthusiasts around the world – chicken dinner is always a winner! Whether you’re having grilled chicken or Caesar salad, or spicing it with some crispy fried chicken nuggets – chicken has a universal appeal for being extremely palatable due to a combination of factors, including its natural flavor profile, adaptability to various cooking methods, and the way it interacts with seasonings and spices. After all, it’s versatile, relatively affordable, and often regarded as a healthier protein option compared to red meat. On top of that, chicken provides vitamins and minerals involved in brain function. It contains vitamin B12 and choline, which together may promote brain development in children, help the nervous system function properly, and aid cognitive performance in older adults.


However, a recent study might change one’s opinion about chicken a little bit.


According to some preliminary research published in Nutrients, consuming chicken is linked with some unexpected health concerns.


Read on to know more.


What does the study say?

The Dietary Guidelines for Americans, 2020–2025, consider poultry to include all kinds of chicken, turkey, duck, geese, and even game birds like quail and pheasant. These guidelines recommend eating around 100 grams of poultry as a standard portion, suggesting it be included in meals about one to three times a week.

This research aimed to address the relatively sparse information regarding the health implications of poultry consumption, particularly in light of concerns about red and processed meats raised by expert panels such as the International Agency for Research on Cancer.


While some studies have suggested potential health benefits of poultry, the evidence is limited. To fill this gap, the researchers explored the relationship between white meat consumption and the risk of early mortality from all causes, as well as gastrointestinal cancers, with a specific emphasis on poultry.


The study included a carefully selected cohort of over 4,000 participants, all of whom provided extensive data through interviews administered by trained medical staff. These interviews gathered critical demographic information, insights into the participants’ general health, lifestyle choices, and personal medical histories. Standardized measurements of height and weight were taken, along with blood pressure readings that complied with international health standards. Significantly, participants were monitored for an average duration of 19 years, allowing for a comprehensive analysis of their health outcomes.

To gain a deeper understanding of dietary habits, participants completed a validated food consumption questionnaire that captured their typical intake patterns. This assessment scaled their meat consumption into categories of red meat, poultry, and total meat, further subdividing each into four intake levels. The researchers meticulously verified the participants’ health status—whether they remained alive, relocated, or deceased—using local municipal records and a regional health database. By comparing these groups, the study aimed to elucidate potential links between different types of meat consumption and mortality rates. Advanced statistical methods were employed to control for confounding factors such as age, sex, and pre-existing health conditions, enhancing the reliability of the findings.


What are the findings?

The results indicated a concerning trend: among participants who succumbed to complications related to gastrointestinal cancers, those consuming the highest quantities of meat every week were most significantly impacted. Specifically, individuals consuming more than 300 grams of poultry weekly demonstrated a 27% heightened risk of mortality compared to those whose poultry intake was less than 100 grams.


This risk appeared to escalate proportionally with increased poultry consumption, surpassing the risk associated with equal portions of red meat. Notably, male participants consuming over 300 grams of poultry each week faced more than double the likelihood of dying from gastrointestinal cancer when compared to their lower-consumption counterparts.

Analyzing the dietary intake of the 1,028 individuals who died during the study, it was revealed that red meat constituted roughly 59% of their total weekly meat consumption, while white meat represented about 41% of the total, with poultry alone accounting for an estimated 29% of that white meat category. Across the board, participants generally adhered to a moderate Mediterranean-style diet, which remained consistent regardless of the specific causes of death.

Interestingly, participants who consumed higher quantities of red meat displayed increased mortality rates from a variety of causes. On average, those who died during the research study regularly consumed more than 200 grams of red meat each week. To contextualize this, approximately 28.35 grams is equivalent to one ounce of red meat; therefore, a typical 8-ounce steak would equate to roughly 227 grams.

Further focusing on white meat, particularly poultry, the study indicated certain mortality associations, especially among those who consumed more than 100 grams of chicken each week. It’s worth noting that while chicken piece sizes can vary, a skinless, boneless breast generally weighs around 174 grams, with a single serving typically being about 85 grams.

Notably, these findings stand in contrast to other research suggesting potential protective effects of higher white meat consumption in relation to gastric cancer risk.


Limitations of the study:

While the findings of the study are certainly concerning, it is essential to consider the study's limitations. For example, the research did not gather specific data on processed poultry consumption or the methods of preparation, as the dietary questionnaire only captured broad poultry consumption patterns.

This lack of detail raises questions about the health outcomes of individuals who may consume fast-food chicken versus those who opt for grilled chicken as part of a nutritious diet. Additionally, the study did not account for participants' physical activity levels—a significant variable in health outcomes—which could potentially skew the observed relationship between diet and health. As an observational study, it is also crucial to recognize that its findings can highlight associations, but not definitively prove causation. Despite these caveats, the research contributes valuable insights to the limited body of literature examining the health implications of poultry consumption.


The bottom line:

The findings from this study provide a valuable lens for reevaluating our typical food choices, especially concerning poultry consumption. If you're someone who regularly enjoys chicken-based meals, this research suggests it might be worth paying closer attention to portion sizes and frequency of consumption.


While this research illuminates potential risks associated with increased poultry consumption, it is vital to consider these findings in the broader context of overall nutrition. It doesn’t mean you have to avoid chicken altogether, but understanding how much you’re eating and balancing it with other protein sources, like fish, legumes, or other plant-based options, may help lower potential health risks. Chicken remains a significant source of protein, rich in essential nutrients such as B vitamins, selenium, and phosphorus, contributing valuable components to a well-rounded diet. However, incorporating diverse foods into your diet can ensure you get a variety of nutrients while possibly minimizing negative outcomes.
