Vegetable and fruit consumption may have a protective effect against several types of cancers. However, the effect on biliary cancers is unclear. We investigated the association of vegetable/fruit consumption with the risks of gallbladder cancer (GBC), intrahepatic bile duct cancer (IHBDC) and extrahepatic bile duct cancer (EHBDC) in a population-based prospective cohort study in Japan. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using the Cox proportional hazard model, and the exposure level was categorized into quartiles, with the lowest group used as the reference. A total of 80,371 people aged 45 to 74 years were enrolled between 1995 and 1999, and followed up for 1,158,632 person-years until 2012, during which 133 GBC, 99 IHBDC, and 161 EHBDC cases were identified. Increased consumption of total vegetable and fruit was significantly associated with a decreased risk of EHBDC (HR = 0.49; 95% CI: 0.29-0.81 for the highest group; p trend = 0.005). From the analysis of relevant nutrients, significantly decreased risk of EHBDC was associated with folate and insoluble fiber (HR = 0.48, 0.53; 95% CI: 0.28-0.85, 0.31-0.88 for the highest group; p trend = 0.010, 0.023; respectively), and a significant trend of decreased EHBDC risk associated with vitamin C was observed (p trend = 0.029). No decreased risk of GBC and IHBDC was found. Our findings suggest that increased vegetable/fruit consumption may decrease a risk of EHBDC, and folate, vitamin C, and insoluble fiber might be key contributors to the observed protective effect.

This descriptive cross-sectional study aimed to investigate whether malnutrition occurs in outpatients with liver cirrhosis, and to compare the nutritional status of patients with alcoholic and viral liver cirrhosis using a variety of objective measures. This study also aimed to provide useful information about nutritional education and nutritional therapies for medical teams and patients with liver cirrhosis. Sixty-six Korean men between the ages of 30 and 69 with liver cirrhosis (24 alcohol-related and 42 virus-related) were recruited from the Internal Medicine Centres, Hanyang University Hospital, Seoul, Korea. The results showed that patients with alcoholic liver cirrhosis (ALC) were significantly lower in socio-economic status than patients with viral liver cirrhosis (VLC) (P<0.05). The energy intakes (excluding alcohol-derived energy) were 1448kcal and 1769kcal in the ALC and the VLC groups, respectively (P<0.05). As well, vitamin C intake was found to be higher in the VLC group than the ALC group, yet still more than 125% of the RDA for both groups (P<0.05). Among nutritional indices, only the TSF thickness showed interaction with the aetiology and the severity of the cirrhosis (P<0.05). Thus, these findings indicate that outpatients with liver cirrhosis in this study, particularly those with alcoholic liver cirrhosis, consumed a lower energy intake than suggested, but may not have been in a status of malnutrition. Body fat is more affected than other nutritional parameters in patients with liver cirrhosis.
