Calcium tied to a 7% lower colorectal cancer risk in Asian meta-analysis — but the confidence interval crossed 1.0, meaning no statistical significance
This is one of the first meta-analyses on calcium and colorectal cancer in Asian populations, and the borderline result means the protective effect is far from settled — treat the finding as hypothesis-generating, not conclusive.
The analysis pooled cohort studies and found that calcium intake was associated with a 7% reduction in colorectal cancer risk (RR 0.93), but the 95% confidence interval ranged from a 14% reduction to no effect at all (0.86–1.00), so the result is not statistically significant. Because the dose of calcium wasn't specified and the evidence is still early for this population, the link remains uncertain — it neither confirms nor rules out a small benefit.
Where this fits in the evidence
This is among the first studies we've indexed on Calcium for Reduced Risk of Colorectal Cancer — treat it as an early signal until more research accumulates.
