Among the 1575 participants, 963 (61.1%) were women; the average age was 68.6 years. With a median follow-up of 8 years, 773 patients died, of which 174 died from colorectal cancer. A high total fiber intake after diagnosis is associated with a lower mortality rate. For every 5g increase in daily intake, the multivariable HR for colorectal cancer specific mortality and all-cause mortality were 0.78 (95% CI 0.65 ~ 0.93; P = 0.006) and 0.86 (95% CI 0.79 ~ 0.93) P <0 .001). According to fiber sources, cereal fiber can reduce Daidaitawa cancer-specific mortality (for every 5 g / d increase in intake, HR = 0.67, 95% CI 0.50 ~ 0.90; P = 0.007) and all-cause mortality (HR = 0.78, 95% CI 0.68 ~ 0.90; P <0.001); vegetable fiber can reduce all-cause mortality (HR = 0.83, 95% CI 0.72 ~ 0.96; P = 0.009), but it does not reduce colorectal cancer-specific mortality (HR = 0.82, 95% CI 0.60 ~ 1.13; P = 0.22); No correlation was found between fruit fiber and mortality. Ingestion of whole wheat food can reduce the specific mortality of colorectal cancer (for every 20 g / d increase in intake, HR = 0.72, 95% CI 0.59 ~ 0.88; P = 0.002), but the correlation It will weaken after entry (HR = 0.77, 95% CI 0.62 ~ 0.96; P = 0.02).
