Hypothesis
Does high intake of animal protein increase the risk of prostate cancer?
Conclusion
A high intake of dairy protein and calcium is associated with an increased risk of prostate cancer.
Supporting Evidence
- A high intake of dairy protein was associated with a 22% increased risk of prostate cancer.
- Calcium from dairy products was positively associated with prostate cancer risk.
- 2727 cases of prostate cancer were diagnosed during the study.
- Follow-up lasted an average of 8.7 years.
Takeaway
Eating a lot of dairy products might make you more likely to get prostate cancer.
Methodology
The study used Cox regression to analyze dietary intake and prostate cancer risk among men in the EPIC cohort.
Potential Biases
Potential biases may arise from self-reported dietary data and participant selection.
Limitations
Dietary intake was estimated using questionnaires, which can lead to measurement errors.
Participant Demographics
Participants were mostly white European men with a median age of 52 at recruitment.
