“…The subjects in this study were participants in other investigation trials, potentially introducing selection bias. It was reported that participants with higher coffee consumption smoked more (29,30), and smokers showed the highest intake of total polyphenols in Europe (11). In our study, the energy-adjusted polyphenol intake in smokers was slightly higher than in non-smokers, but the number of smokers was not high enough to analyze CVw, coefficient of within-individual variation; CVb, coefficient of between-individual variation; VR, within-to betweenindividual variance ratio.…”

Summary Polyphenol intake has been estimated in some populations; however, information about day-to-day and individual differences in polyphenol intake has not been wellevaluated. In this study, we aimed to examine within-and between-individual variation in polyphenol intake in Japanese male workers. First, 56 male subjects (aged 37.9610.4 y) completed detailed 7-d dietary records (DR). We then calculated their total polyphenol intake using our polyphenol content database and the within-and between-individual variations. We also estimated the minimum number of days of dietary assessment required both to rank individuals within a group and to assess an individual's usual polyphenol intake with acceptable accuracy. The estimated daily total polyphenol intake was 9656471 mg/d, which was largely sourced from beverages. The day-to-day variation (CVw) for polyphenol intake was 43.6%, and the variation between the individuals in the population (CVb) for polyphenol intake was 45.9%. A 4-d DR was required to rank individuals within a group with high correlation coefficients (r50.9), and a 19-d DR was required to assess the individual's usual polyphenol intake with 20% deviation. The CVw for polyphenol intake was intermediate between those of the other nutrients, but the CVb for polyphenol intake was largest among the nutrients. These results suggest that the dietary intake of polyphenols should be carefully estimated considering its within-and between-individual variation.

“…The main outcomes were all‐sites cancer incidence and mortality. We used the International Classification of Diseases, 9th revision (ICD‐9), for data between 1983 and 1994, and the 10th revision (ICD‐10), for data between 1995 and 2000, to classify the all‐sites cancer (ICD‐9, codes 140–208; ICD‐10, codes C00–C97) …”

Association between coffee consumption and all‐sites cancer incidence and mortality

The preventive effect of coffee on cancer at different sites has been reported, but the effect on all‐sites cancer incidence has not been extensively investigated. We evaluated the association between frequency of coffee consumption and risk of all‐sites cancer incidence and mortality among 39 685 men and 43 124 women (age 40–79 years, at baseline), in the Three‐Prefecture Cohort Study. The association between frequency of coffee consumption and risk of all‐sites cancer incidence and mortality was assessed by a Cox proportional hazards regression model, adjusted for potential confounders. During 411 341 person‐years among men and 472 433 person‐years among women, a total of 4244 men and 2601 women developed cancer at different sites and a total of 3021 men and 1635 women died of cancer at different sites. We showed an inverse association between frequency of coffee consumption and all‐sites cancer incidence in both men and women. Comparing participants who consumed coffee with those who never drank coffee, the adjusted hazard ratios (95% confidential interval) for all‐sites cancer incidence was 0.74 (0.62–0.88) for coffee consumption of ≥5 cups/day in men (P for trend < 0.001) and 0.76 (0.58–1.02) in women (P for trend = 0.020). Coffee consumption frequency was inversely associated with mortality from all‐sites cancer. In this population, increasing coffee consumption resulted in a decreased risk of all‐sites cancer incidence and mortality.

“…Because Saito et al showed in another report (6) that coffee consumption was also inversely associated with mortality from heart disease, cerebrovascular disease, and respiratory disease in Japan, caffeine, which is one of the active substances in green tea, was suggested to produce health benefits. However, greater efforts have been put into the investigation of green tea catechins, in particular of epigallocatechin gallate (EGCG), which is the main gallate-type catechin in green tea.…”

Summary Studies have suggested that the consumption of green tea reduces the risk of cardiovascular diseases. Although epigallocatechin gallate (EGCG) is the best studied active substance characteristic of green tea, previous results on EGCG do not appear sufficient to explain completely the mechanism of cardiovascular protection by green tea. Therefore, we investigated the effect of three different tea cultivars, "Yabukita," "Sofu," and "Sunrouge," which have characteristic flavonoid compositions, on the nitric oxide (NO) production and the related protein expression in the aorta of spontaneously hypertensive rats (SHRs) fed a high-salt diet. As a result, the reduction of urinary NO metabolite (NOx) levels, which reflect whole-body NO production, caused by the high-salt diet were significantly prevented by all three tea infusions. The improvement of NOx reduction in the tea-intake groups was unlikely to be caused by the changes in oxidative damage. On the other hand, as a partial effect, only "Yabukita" or "Sofu" increased the expression of the soluble guanylate cyclase, a receptor for NO, in the thoracic aorta. In the present study, the differences in the composition of these three cultivars led to partially different effects on NO signaling in SHRs, suggesting the physiological significance of subdominant ingredients besides EGCG.
