A recent study from Harvard University has found a potential connection between egg consumption and the risk of developing certain types of cancer, including breast, ovarian, and fatal prostate cancer. The findings, published in the British Journal of Nutrition, suggest that eating eggs may influence the development of cancers related to sex hormones.
Led by researcher N. Keum and colleagues, the study analyzed data from multiple studies using a method called dose-response meta-analysis. This approach allowed the team to examine how different levels of egg consumption might impact cancer risk. Their results suggest that eating more eggs could be linked to a higher likelihood of developing some cancers.
For breast cancer, the study found that consuming five or more eggs per week was associated with an increased risk compared to those who did not eat eggs. The same trend was observed for ovarian cancer and fatal prostate cancer. However, no connection was found between egg intake and the overall risk of developing prostate cancer—only its most severe form.
While the study indicates a possible link, the researchers emphasize that these findings do not prove that eggs directly cause cancer. More research is needed to understand the biological mechanisms behind this association and whether other factors, such as overall diet or lifestyle, play a role.
Eggs are a staple food in many diets, known for their high-quality protein and essential nutrients. However, they also contain cholesterol and other compounds that may affect hormone levels or pathways linked to cancer.
Some earlier studies have suggested a connection between egg intake and cancers influenced by sex hormones, but the exact relationship remains unclear.
This research adds to the ongoing discussion about the health effects of egg consumption. While eggs can be part of a healthy diet, moderation may be important, particularly for individuals concerned about hormone-related cancers.
Understanding how diet influences cancer risk is an essential part of disease prevention. This study highlights the need for further research to provide clearer guidance on egg consumption and its potential long-term effects on health.
