A new study from Harvard University suggests there may be a link between eating eggs and a higher risk of some types of cancer.
These include breast cancer, ovarian cancer, and deadly prostate cancer. The study was published in the British Journal of Nutrition.
The researchers, led by N. Keum, looked at information from many previous studies. They used a method called dose-response meta-analysis, which helps show how different amounts of a food might affect health. In this case, they looked at how eating more or fewer eggs could change the risk of cancer.
Their results showed that people who ate five or more eggs a week had a higher risk of developing breast cancer than those who didn’t eat eggs.
The same pattern was seen with ovarian cancer and the most serious type of prostate cancer. But the study didn’t find a link between egg eating and the overall risk of prostate cancer—only its most deadly form.
It’s important to know that this study doesn’t prove that eggs cause cancer. It only shows a possible connection. The researchers say more studies are needed to find out how eggs might be linked to these cancers and if other things—like diet, exercise, or other lifestyle habits—are also involved.
Eggs are a common food that many people eat often. They are full of good nutrients like protein and vitamins. But they also contain cholesterol and other substances that could affect hormone levels in the body. Hormones can sometimes play a role in how certain cancers develop.
In the past, some studies have hinted at a link between eating eggs and cancers affected by sex hormones. But the results have not always been clear, and scientists still don’t fully understand how eggs might be involved.
This new research adds to the debate. It suggests that people may want to be careful about how many eggs they eat, especially if they are worried about cancers linked to hormones. It doesn’t mean you have to stop eating eggs, but eating them in moderation could be a safer choice.
Learning more about how food affects our health is very important. This study shows that scientists are still working to understand the long-term effects of what we eat. More research will help give better advice about whether eggs are safe to eat often, or if they should be limited.
For now, if you enjoy eggs, you don’t have to give them up completely. But it may be smart to balance them with other healthy foods and talk to your doctor if you have concerns about cancer risk.
