ObjectiveTo examine the possible relationship between tea consumption and risk of gastric cancer (GC) among Japanese men and women included in a large Japanese population-based study titled the Japan Collaborative Cohort (JACC) Study.DesignProspective cohort study.SettingA population-based cohort included subjects who were recruited from 24 areas of JACC Study, in which data regarding the incidence of cancer were available.Participants63 848 participants (26 025 men and 37 823 women), aged 40–79, were included in the analyses and underwent follow-up (median 13.3 years) prospectively in research on cancer incidence.Primary and secondary outcome measuresThe primary outcome variable was the risk of GC according to the frequency intakes of total tea, green tea, black tea and oolong tea. The adjusted HRs for the risk of GC associated with tea consumption were calculated using the Cox proportional hazards model.Results1494 cases of GC were detected (960 men and 534 women) during the follow-up period. The multivariable-adjusted HRs for the risk of GC in the highest versus lowest quintiles of total tea intake were 1.05 (0.83–1.33); p trend=0.50 in men, and 0.82 (0.60–1.12); p trend=0.45 in women. There was no association found between the consumption of green tea, black tea or oolong tea with the risk for GC in either gender.ConclusionsIn this large community-based prospective cohort study, tea consumption was not associated with the risk of GC in either gender.

Abstract The association between the intake of non-alcoholic beverages and cardiovascular disease in Asians is uncertain. The intake of non-alcoholic beverages was estimated in 77,407 participants of the Japan public health center-based cohort study aged 45-74 years. The Cox regression calculated the HRs and 95% CIs for incident cardiovascular disease according to sex-specific quintiles of intake of non-alcoholic beverages. A total of 4578 incident cardiovascular disease (3,751 strokes and 827 coronary heart disease) were diagnosed during a 13.6-year median follow-up. The risks of stroke and total cardiovascular disease were lower for the highest versus lowest intake quintiles of non-alcoholic beverages in men and women: the multivariable HRs (95%CIs) were 0.82 (0.71-0.93, p-trend=0.005) and 0.86 (0.76-0.97, p-trend=0.02), respectively in men, and were 0.73 (0.63-0.86, p-trend=0.003) and 0.75 (0.65-0.87, p-trend=0.005) respectively in women. The reduced risk was evident for both ischemic and hemorrhagic strokes and was mainly attributable to green tea consumption. The intake of non-alcoholic beverages from coffee and other beverages was not associated with the risk of cardiovascular disease in both men and women. Also, there was no association between the intake of non-alcohol beverages and the risk of coronary heart disease in either sex. In conclusion, the risks of stroke and total cardiovascular disease were lower with a higher intake of non-alcoholic beverages in Japanese men and women.

Tannase was effectively immobilized on alginate by the method of crosslinking-entrapment-crosslinking with a high activity recovery of 76.6%. The properties of immobilized tannase were investigated. Its optimum temperature was determined to be 35 ° C, decreasing 10 °C compared with that of free enzyme, whereas the optimum pH of 5.0 did not change. The thermal and pH stabilities of immobilized tannase increased to some degree. The kinetic parameter, Km, for immobilized tannase was estimated to be 11.6 × 10-4 mol/L. Fe2+ and Mn2+ could activate the activity of immobilized tannase. The immobilized tannase was also applied to treat the tea beverage to investigate its haze-removing effect. The content of non-estern catechins in green tea, black tea and oolong tea increased by 52.17%, 12.94% and 8.83%, respectively. The content of estern catechins in green tea, oolong tea and black tea decreased by 20.0%, 16.68% and 5.04%, respectively. The anti-sediment effect of green tea infusion treated with immobilized tannase was significantly increased. The storage stability and reusability of the immobilized tannase were improved greatly, with 72.5% activity retention after stored for 42 days and 86.9% residual activity after repeatedly used for 30 times.
