Overview

Sandhu S et al.. J Urol 2026 · PMID 42607142 · DOI 10.1097/JU.0000000000005263

Most studies found no link at around 2.5-3 eggs per week; one found a link at about 5.5 per week.

Does the study support the specific claim? Unclear · Methodological quality: moderate

Study explained simply

What did the researchers want to find out?: Review diet after diagnosis and prostate cancer outcomes.
How was the study done?: Systematic review.
How many people, animals or samples were studied?: 6 cohorts.
What was actually found?: Inconsistent evidence for eggs.
How large was the observed effect?: Not pooled.
What do the results mean in everyday life?: The link between eggs and deadly prostate cancer remains unproven.
What are the study's limitations?: Few studies.
What does it say about Elawady's specific claim?: Does not confirm the 81% figure.
Do the results apply to Germany and Europe?: Moderate.
What can explicitly not be concluded from this study?: It cannot exclude a risk at very high intakes.

Is postdiagnostic intake of red meat, poultry and eggs associated with prostate cancer progression and mortality?

Study design: Systematic review – Systematic review of prospective cohorts (no meta-analysis)
Population: Men with prostate cancer in 6 cohorts (>10,000 men)
Country: Multinational
Period: Search to 17 July 2025
Sample size: >10,000 men; 6 cohorts
Inclusion and exclusion criteria: not detailed in abstract

Exposure / intervention: Postdiagnostic egg (and meat/poultry) intake
Comparator: Lower intake
Endpoints: Progression, prostate cancer-specific mortality, all-cause mortality
Statistical methods: Narrative synthesis with risk-of-bias assessment

Results: Egg evidence inconsistent: a positive association with progression in 1 study with very high intake in the top category (~5.5 servings/week); no associations in 4 studies with top categories of >=2.5-3 servings/week; 1 of 2 studies showed a positive association with all-cause mortality.
Absolute risks: not reported
Authors' conclusion: Evidence is limited and inconsistent; progression risk may be specific to higher egg intake (>3-5 servings/week).

Not pooled; inconsistent findings.

Up-to-date synthesis showing that egg-prostate cancer findings are inconsistent; no association at the 2.5-3/week level in most studies.

One study with high intake found a positive association.

Mixed.

Supports 'unclear' rather than an established risk.
