Ti G, He Y, Xiao Y, Yan J, Ding R, Cheng P, Wu W, Ye D, Wang J, Li L. Global prevalence of diet low in calcium and the disease burden: results from the Global Burden of Disease Study 2019. Nutr Diabetes 2024; 14:59. [PMID: 39097595 PMCID: PMC11297965 DOI: 10.1038/s41387-024-00321-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 07/15/2024] [Accepted: 07/24/2024] [Indexed: 08/05/2024] Open
Abstract
BACKGROUND Due to the essential role of calcium in vital biological functions, diet low in calcium (DLC) is associated with various diseases. However, there is a lack of study about the current prevalence and health burden due to DLC using reliable data sources. METHODS We used data from the Global Burden of Disease study 2019 (GBD 2019) to estimate the prevalence and health burden of DLC in 204 countries from 1990 to 2019, by age, sex, and sociodemographic index (SDI). The estimates were produced in DisMod-MR 2.1, a Bayesian meta-regression tool. Summary exposure value (SEV) was used to show the prevalence of DLC, while diseases adjusted life year (DALY) was used to represent the disease burden. The disease burden was estimated for DLC-induced colorectal cancer. Spearman Rank Order correlation was used for correlation analysis, and estimated annual percentage (EAPC) was used to reflect the temporal trends. RESULTS From 1990 to 2019, the global prevalence of DLC decreased (EAPC of SEV, -0.47; 95% CI, -0.5 to -0.43), but have increased in Oceania region and in many countries, such as United Arab Emirates, New Zealand, Japan, and France. The global DALYs associated with low in calcium were estimated to be 3.14 million (95% uncertainty interval (UI), 2.25-4.26 million) in 2019, with an age standardized rate of 38.2 (95% UI, 27.2-51.8) per 100,000. Unlike the prevalence, the global age standardized DALY rates has remained unchanged (EAPC, -0.03; 95% CI, -0.12 to 0.07), but has increased in over 80 of the 204 countries, located mainly in Asia, Africa, and South America. In all years and regions, the age standardized SEV and DALY rates were higher in male people than that in female people. The prevalence (rho = -0.823; P < 0.001) and disease burden (rho = -0.433; P < 0.001) associated with diet in low calcium were strongly correlated to SDI. The prevalence decreased with age, but the DALY rates increased with age and peaked at about 90 years. The prevalence of DLC has decreased worldwide and in most countries, but the disease burden of DLC induced colorectal cancer has increased in over 40% of countries worldwide. CONCLUSION Countries with low sociodemographic level and male people are more likely to experience the risk of DLC and related disease burden. Related measures in improve dietary calcium intake are in need to address diet in low calcium related health problems.

Super-additive associations between parity and education level on mortality from cardiovascular disease and other causes: the Japan Collaborative Cohort Study. BMC Womens Health 2022; 22:278. [PMID: 35794595 PMCID: PMC9261019 DOI: 10.1186/s12905-022-01805-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 05/25/2022] [Indexed: 11/19/2022] Open
Abstract
Background While women’s parity status and education level have independent associations with cardiovascular and other diseases, no studies have evaluated the additive interaction of these two factors. Therefore, we examined the additive interaction between parity and education level on mortality from stroke, coronary heart disease, total cardiovascular disease, cancer, non-cardiovascular disease, and non-cancer causes, and all causes in Japanese women. Methods This study followed 41,242 women aged 40–79 years without a history of cardiovascular disease or cancer from 1988 to 1990 until 2009. Baseline parity and education level were classified into four categories, with highly educated parous women as the reference group. Cox proportional hazards regression analyses were performed to calculate the risk of mortality. We also assessed the additive interactions between parity and education level on mortality from cardiovascular disease and other causes using the relative excess risk due to interaction obtained using Cox models. Results During the median follow-up period of 19.1 years, we identified 6299 deaths. In a multivariable model adjusted for cardiovascular disease and other disease risk factors, nulliparous women with low education levels had increased multivariable-adjusted hazard ratios of 1.67 (95% confidence interval [CI] 1.13, 2.47) for stroke, 1.98 (95% CI 1.15, 3.39) for coronary heart disease, 1.71 (95% CI 1.34,2.18) for total cardiovascular disease, 1.69 (95% CI 1.33, 2.14) for non-cardiovascular and non-cancer, and 1.51 (95% CI 1.30, 1.75) for all-cause mortality when compared with highly educated parous women. Moreover, we observed significant additive interactions between parity and education level on total cardiovascular disease mortality (P = 0.04), non-cardiovascular disease and non-cancer mortality (P = 0.01), and all-cause mortality (P = 0.005). Conclusions Nulliparity and low education levels are super-additively associated with total cardiovascular disease, non-cardiovascular and non-cancer, and all-cause mortality risks, suggesting that nulliparous women with low education levels need specific support for preventing mortality related to cardiovascular and other diseases.

Dairy products and the risk of developing prostate cancer: A large-scale cohort study (JACC Study) in Japan. Cancer Med 2021; 10:7298-7307. [PMID: 34606688 PMCID: PMC8525158 DOI: 10.1002/cam4.4233] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2021] [Revised: 07/23/2021] [Accepted: 08/08/2021] [Indexed: 11/28/2022] Open
Abstract
Dairy products have been indicated as a risk factor for prostate cancer. However, only a few epidemiological studies have reported dairy products as being a risk factor for prostate cancer in Japan, reporting contradictory results. We therefore investigated the association between the intake of dairy products and the occurrence of prostate cancer through a large‐scale cohort study. The Japan Collaborative Cohort study analyzed approximately 110,000 residents from various Japanese districts who participated in our questionnaire survey during 1988–1990. The subjects of the present study were 26,464 men (age range: 40–79 years) from 24 districts wherein cancer incidence was reported. Their clinical course was followed up until 2009. Hazard ratios (HRs) were calculated using Cox's proportional hazards model, adjusted for age, survey area, family history of prostate cancer, body mass index, and total energy intake. For diet, we calculated the HRs associated with intermediate and high consumption of dairy products and compared them with those associated with low consumption. There were 412 cases of prostate cancer in the survey population. As dairy products, milk, yogurt, cheese, and butter were evaluated. Among them, milk consumption was associated with a significant risk (HR = 1.37, p = 0.009) and a dose‐dependent response (p for trend = 0.009) adjusted for age and family history of prostate cancer, stratified by area. Milk and yogurt consumption showed a significantly positive risk and a dose–response relationship adjusted for age, family history of prostate cancer, body mass index, and total energy intake, stratified by area. In summary, a high intake of dairy products such as milk increased the risk of developing prostate cancer in Japanese men.

Abstract
Diet plays an important role in the regulation of chronic inflammation, which is linked to cardiovascular disease (CVD) and several cancers. The dietary inflammatory index (DII®) was developed to estimate the inflammatory potential of an individual’s diet. We examined the association between DII scores and serum high-sensitivity C-reactive protein (hs-CRP) concentrations using the baseline data from the Japan Collaborative Cohort Study (JACC Study). Data were from 1176 control subjects (650 men and 526 women) in a nested case-control study of several cancers and CVD in the JACC Study who were free of cancer and CVD at baseline. DII scores were calculated from 26 food parameters that were derived from a validated food frequency questionnaire administered at the baseline. Energy-adjusted DII scores were calculated using the residual method. Serum hs-CRP concentrations were measured by latex-enhanced nephelometry or enzyme-immunoassay. In multivariable logistic regression analysis adjusting for potential confounders including sex, age, smoking habits, drinking habits, body mass index, and history of hypertension, the odds ratio (OR) and 95% confidence intervals (CI) for high serum hs-CRP concentrations (>1.0 mg/L) was significantly higher in the highest versus the lowest DII quartile (ORQuartile4vs1 = 1.32, 95% CI = 1.01 to 2.52). Likewise, a 1-point increase in DII score was associated with a 14% increased risk of high serum hs-CRP concentrations (ORContinuous = 1.09, 95%CI = 1.01 to 1.19). A pro-inflammatory diet, as represented by high DII scores, was associated with high serum hs-CRP concentrations in this Japanese population.

Abstract
BACKGROUND NAFLD is increasing in Asia including Japan, despite its lower obesity rate than the West. However, NAFLD can occur in lean people, but data are limited. We aimed to investigate the epidemiology of NAFLD in Japan with a focus on lean NAFLD. METHODS We searched PubMed, Cochrane Library, EMBASE, Web of Science, and the Japan Medical Abstracts Society (inception to 5/15/2019) and included 73 eligible full-text original research studies (n = 258,531). We used random-effects model for pooled estimates, Bayesian modeling for trend and forecasting, contacted authors for individual patient data and analyzed 14,887 (7752 NAFLD; 7135 non-NAFLD-8 studies) patients. RESULTS The overall NAFLD prevalence was 25.5%, higher in males (p < 0.001), varied by regions (p < 0.001), and increased over time (p = 0.015), but not by per-person income or gross prefectural productivity, which increased by 0.64% per year (1983-2012) and is forecasted to reach 39.3% in 2030 and 44.8% in 2040. The incidence of NAFLD, HCC, and overall mortality were 23.5, 7.6 and 5.9 per 1000 person-years, respectively. Individual patient-level data showed a lean NAFLD prevalence of 20.7% among the NAFLD population, with lean NAFLD persons being older and with a higher all-cause mortality rate (8.3 vs. 5.6 per 1000 person-years for non-lean NAFLD, p = 0.02). Older age, male sex, diabetes, and FIB-4 were independent predictors of mortality, but not lean NAFLD. CONCLUSION NAFLD prevalence has increased in Japan and may affect half of the population by 2040. Lean NAFLD individuals makeup 20% of the NAFLD population, were older, and had higher mortality.

Abstract
The functional food market is one of the fastest growing segments of the global food industry. The aims of this study were to understand the association of demographic characteristics and food choice motives (FCMs) with (a) attitudes toward functional foods and (b) consumption of functional foods in Australian emerging adults. Data were collected through a paper-based and online questionnaire completed by 370 young adults aged between 17 and 29 years. A binomial logistic regression was used to determine the association between demographic characteristics and FCMs with attitudes towards functional foods. The logistic regression model was statistically significant at χ2(11) = 48.310 (p < 0.001) and explained 18.1% of the variance in attitude towards functional food. Of the several predictors, only the FCMs natural content and weight control were statistically significant. A binomial logistic regression was also used to determine the association between demographic characteristics and FCMs with the consumption of functional foods. The logistic regression model was statistically significant at χ2(9) = 37.499 (p < 0.001) and explained 14.1% of the variance in functional food consumption. Of the eight predictors, three were statistically significant: living situation, natural content and health. Findings highlight that when targeting emerging adults, functional food companies could benefit from promoting the natural and health properties of their products. Furthermore, consumption can be increased by targeting the parents of emerging adults and by designing functional foods that attract emerging adults interested in controlling weight.

Abstract
Purpose To assess the association of dietary saturated fatty acid (SFA) intake with the presence of early AMD in a Japanese population. Methods The population-based Tsuruoka Metabolomics Cohort Study enrolled general population individuals aged 35 to 74 years from among participants in annual health check-up programs that included fundus photographs in Tsuruoka, Japan. A total of 4010 individuals participated in the baseline survey. After excluding nonresponders to a dietary survey and participants with suboptimal fundus image quality, 3988 participants (median age, 62.4 years) were included in this cross-sectional analysis. Dietary intake was assessed by a validated food frequency questionnaire. Fatty acids intake was adjusted for total energy intake by the residuals method. The association between fatty acid intake and presence of early AMD was assessed by logistic regression models. Results Median daily SFA intake was 11.3 g (interquartile range, 9.6, 13.0 g). After adjustments for potential confounding factors, participants in the highest quartile of SFA intake were less likely to have early AMD, compared with the lowest quartile (odds ratio, 0.71; 95% confidence interval: 0.52–0.96). A significant trend for decreased risk of early AMD with increasing SFA intake was noted (P = 0.011). There was no significant association between poly-unsaturated fatty acid (PUFA) including n3-PUFA intake and early AMD. Conclusions We found that increased SFA intake was associated with reduced risk of early AMD in a Japanese population with low SFA intake. Adequate fatty acid intake may be required to maintain retinal homeostasis and prevent AMD.

Abstract
BACKGROUND The Dietary Inflammatory Index (DII) is a comprehensive, literature-derived index for assessing the effect of dietary constituents on inflammatory biomarkers. Several studies have shown an association between DII score and mortality, but there are limited prospective studies in Asian populations. OBJECTIVES The aim of this study was to investigate the association between DII score and risk of all-cause, total cardiovascular disease (CVD), stroke, coronary heart disease (CHD), total cancer, digestive cancer, and noncancer/non-CVD mortality in the Japanese population. METHODS A total of 58,782 Japanese participants aged 40-79 y who were enrolled in the Japan Collaborative Cohort Study during 1988-1990 were included in the analysis. DII scores were calculated based on a food-frequency questionnaire. HRs and 95% CIs for mortality according to DII quintiles were estimated using Cox proportional hazards models. RESULTS During the median follow-up period of 19.3 y, a total of 11,693 participants died. The multivariable HR for all-cause mortality for the highest compared with the lowest DII quintiles was 1.13 (95% CI: 1.05, 1.21). For CVD mortality, the highest multivariable HRs were 1.30 (95% CI: 1.13, 1.49), 1.29 (95% CI: 1.05, 1.59), and 1.30 (95% CI: 0.96, 1.76) for total CVD, stroke, and CHD, respectively. No significant associations were observed between DII and risk of total cancer, digestive cancer, and noncancer/non-CVD mortality. CONCLUSION Our findings suggest that a higher DII was associated with an increased risk of all-cause and CVD mortality among Japanese adults.

Abstract
Few studies have reported the association between the Japanese diet as food score and mortality. This study aimed to investigate adherence to the Japanese food score associated with all-cause, CVD and cancer mortality. A total of 58,767 (23,162 men and 35,605 women) Japanese participants aged 40-79 years, who enrolled in the Japan Collaborative Cohort Study between 1988 and 1990, were included. The Japanese food score was derived from the components of seven food groups (beans and bean products, fresh fishes, vegetables, Japanese pickles, fungi, seaweeds and fruits) based on the FFQ. The total score ranged from 0 to 7, and participants were divided into five categories based on scores (0-2, 3, 4, 5 and 6-7). Hazard ratios (HR) and 95 % CI for all-cause, CVD and cancer mortality based on sex were estimated using Cox proportional models. During the follow-up period until 2009, 11 692 participants with all-cause, 3408 with CVD and 4247 with cancer died. The multivariable HR in the 6-7 and 0-2 Japanese food score groups were 0·93 (95 % CI 0·86, 1·01) in men and 0·82 (95 % CI 0·75, 0·90) in women for all-cause mortality and 0·89 (95 % CI 0·76, 1·04) in men and 0·66 (95 % CI 0·56, 0·77) in women for CVD mortality. Our findings suggest that adherence to the Japanese food score consisting of food combinations characterised by a Japanese diet may help in preventing all-cause and CVD mortality, especially in women.

Abstract
The red seaweed, Kappaphycus alvarezii, was evaluated for its potential to prevent signs of metabolic syndrome through use as a whole food supplement. Major biochemical components of dried Kappaphycus are carrageenan (soluble fiber ~34.6%) and salt (predominantly potassium (K) 20%) with a low overall energy content for whole seaweed. Eight to nine week old male Wistar rats were randomly divided into three groups and fed for 8 weeks on a corn starch diet, a high-carbohydrate, high-fat (H) diet, alone or supplemented with a 5% (w/w) dried and milled Kappaphycus blended into the base diet. H-fed rats showed symptoms of metabolic syndrome including increased body weight, total fat mass, systolic blood pressure, left ventricular collagen deposition, plasma triglycerides, and plasma non-esterified fatty acids along with fatty liver. Relative to these obese rats, Kappaphycus-treated rats showed normalized body weight and adiposity, lower systolic blood pressure, improved heart and liver structure, and lower plasma lipids, even in presence of H diet. Kappaphycus modulated the balance between Firmicutes and Bacteroidetes in the gut, which could serve as the potential mechanism for improved metabolic variables; this was accompanied by no damage to the gut structure. Thus, whole Kappaphycus improved cardiovascular, liver, and metabolic parameters in obese rats.

Abstract
Seaweed has been considered an indigestible food. Fucoidan, which is found abundantly in seaweed, especially in Cladosiphon okamuranus (Okinawa mozuku), has a high molecular weight and has been long believed to be hardly absorbed in the human digestive system due to a lack of certain digestive enzymes. We previously reported that fucoidan can be detected in serum and urine after oral intake of purified fucoidan in humans and rats. However, it is unclear whether the fucoidan in mozuku can be absorbed after digestion of mozuku. Therefore, we attempted to detect fucoidan in urine before and after mozuku intake. We determined the fucoidan concentration in urine after oral intake of Okinawa mozuku and urinary fucoidan was detected in several volunteers. In conclusion, these results suggest that fucoidan in mozuku can be absorbed after ingestion of mozuku.

Abstract
The pace of anti-diabetic drug discovery is very slow in spite of increasing rate of prevalence of Type 2 Diabetes which remains a major public health concern. Though extensive research steps are taken in the past decade, yet craves for better new treatment strategies to overcome the current scenario. One such general finding is the evolution of gliptins which discriminately inhibits DPP4 (Dipeptidyl peptidase-4) enzyme. Although the mechanism of action of gliptin is highly target oriented and accurate, still its long-term use stands unknown. This step calls for a fast, flexible, and cost-effective strategies to meet the demands of producing arrays of high-content lead compounds with improved efficiency for better clinical success. The present review highlights the available gliptins in the market and also other naturally occurring DPP4 enzyme inhibitors. Along with describing the known inhibitors and their origin in this review, we attempted to identify a probable new lead compounds using advanced computational techniques. In this context, computational methods that integrate the knowledge of proteins and drug responses were utilized in prioritizing targets and designing drugs towards clinical trials with better efficacy. The compounds obtained as a result of virtual screening were compared with the commercially available gliptin in the market to have better efficiency in the identification and validation of the potential DPP4 inhibitors. The combinatorial computational methods used in the present study identified Compound 1: 25022354 as promising inhibitor.

Abstract
Pregnancy represents a challenge from a nutritional perspective, because micronutrient intake during the periconceptional period and in pregnancy affects fetal organ development and the mother's health. Inappropriate diet/nutrition in pregnancy can lead to numerous deficiencies including iron deficiency and may impair placental function and play a role in miscarriage, intrauterine growth restriction, preterm delivery, and preeclampsia. This article reviews the risks associated with nutrient deficiencies in pregnant women and presents an overview of recommendations for dietary supplementation in pregnancy, focusing on oral iron supplementation. Risk factor detection, including dietary patterns and comorbidities, is paramount in optimal pregnancy management. Dietary habits, which can lead to deficiencies (e.g., iron, folate, vitamin D, and calcium) and result in negative health consequences for the mother and fetus/newborn, need to be investigated. Prenatal care should be personalized, accounting for ethnicity, culture, education, information level about pregnancy, and dietary and physical habits. Clinicians should make a plan for appropriate supplementation and prophylaxis/treatment of nutritional and other needs, and consider adequate intake of calcium, iodine, vitamin D, folate, and iron. Among the available oral iron supplements, prolonged-released ferrous sulfate (ferrous sulfate-polymeric complex) presents the lowest incidence of overall and gastrointestinal adverse events, with positive implications for compliance.

Abstract
BACKGROUND Breakfast eating habits are a dietary pattern marker and appear to be a useful predictor of a healthy lifestyle. Many studies have reported the unhealthy effects of skipping breakfast. However, there are few studies on the association between skipping breakfast and mortality. In the present study, we examined the association between skipping breakfast and mortality from cancer, circulatory diseases and all causes using data from a large-scale cohort study, the Japan Collaborative Cohort Study (JACC) Study. METHODS A cohort study of 34,128 men and 49,282 women aged 40-79 years was conducted, to explore the association between lifestyle and cancer in Japan. Participants completed a baseline survey during 1988 to 1990 and were followed until the end of 2009. We classified participants into two groups according to dietary habits with respect to eating or skipping breakfast and carried out intergroup comparisons of lifestyle. Multivariate analysis was performed using the Cox proportional hazard regression model. RESULTS There were 5,768 deaths from cancer and 5,133 cases of death owing to circulatory diseases and 17,112 cases for all causes of mortality during the median 19.4 years follow-up. Skipping breakfast was related to unhealthy lifestyle habits. After adjusting for confounding factors, skipping breakfast significantly increased the risk of mortality from circulatory diseases [hazard ratio (HR) = 1.42] and all causes (HR = 1.43) in men and all causes mortality (HR = 1.34) in women. CONCLUSION Our findings showed that skipping breakfast is associated with increasing risk of mortality from circulatory diseases and all causes among men and all causes mortality among women in Japan.

Abstract
BACKGROUND Most previous prospective studies in Western countries found no association between consumption of fish and n-3 (ω-3) polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA), for which the main source is fish, and pancreatic cancer risk. However, prospective evidence is still lacking among populations who have a relatively higher fish consumption. OBJECTIVE We investigated the association between fish and n-3 PUFA consumption and pancreatic cancer risk in a population-based, prospective study in Japanese men and women. DESIGN The Japan Public Health Center-based Prospective Study (JPHC study) has enrolled 140,420 subjects. We analyzed data on 82,024 eligible participants aged 45-74 y without a history of cancer who responded to a validated food-frequency questionnaire that included 138 items in 1995 for cohort I and in 1998 for cohort II. Participants were followed through 2010. HRs and corresponding 95% CIs for the highest compared with lowest quartile were calculated by using multivariable-adjusted Cox proportional hazards regression models. RESULTS During 1,068,774 person-years of follow-up, 449 newly diagnosed pancreatic cancers were identified. After the exclusion of pancreatic cancer cases in the first 3 y of follow-up, we found an inverse association of marine n-3 PUFA (EPA+DPA+DHA) and DHA consumption with pancreatic cancer risk: compared with the lowest quartile, multivariate-adjusted HRs in the highest quartile were 0.70 (95% CI: 0.51, 0.95; P-trend = 0.07) and 0.69 (0.51, 0.94; P-trend = 0.03), respectively. Associations for total fish, n-3 PUFA, EPA, and DPA consumption were similar but were not significant. CONCLUSION High n-3 PUFA, especially marine n-3 PUFAs, and DHA consumption was associated with a lower risk of pancreatic cancer in a population with a large variation in fish consumption, although the data apply to only a portion of the JPHC study subjects.

Abstract
Diabetes mellitus is a group of metabolic disorders of the endocrine system characterised by hyperglycaemia. Type II diabetes mellitus (T2DM) constitutes the majority of diabetes cases around the world and are due to unhealthy diet, sedentary lifestyle, as well as rise of obesity in the population, which warrants the search for new preventive and treatment strategies. Improved comprehension of T2DM pathophysiology provided various new agents and approaches against T2DM including via nutritional and lifestyle interventions. Seaweeds are rich in dietary fibres, unsaturated fatty acids, and polyphenolic compounds. Many of these seaweed compositions have been reported to be beneficial to human health including in managing diabetes. In this review, we discussed the diversity of seaweed composition and bioactive compounds which are potentially useful in preventing or managing T2DM by targeting various pharmacologically relevant routes including inhibition of enzymes such as α-glucosidase, α-amylase, lipase, aldose reductase, protein tyrosine phosphatase 1B (PTP1B) and dipeptidyl-peptidase-4 (DPP-4). Other mechanisms of action identified, such as anti-inflammatory, induction of hepatic antioxidant enzymes’ activities, stimulation of glucose transport and incretin hormones release, as well as β-cell cytoprotection, were also discussed by taking into consideration numerous in vitro, in vivo, and human studies involving seaweed and seaweed-derived agents.

Abstract
Background The evidence for an association between low intake of vegetables and fruits and increased colorectal cancer risk is inconclusive. Evaluating the colorectal cancer risk associated with continued low intake is important. Methods We used data of 45 516 and 14 549 subjects aged 40–79 years obtained in the baseline and interim surveys, respectively, from the Japan Collaborative Cohort Study for Evaluation of Cancer Risk (JACC Study). The intake frequency of vegetables and fruits as assessed by a self-administered questionnaire was classified into tertiles of low, middle, and high groups, and the low group was subdivided into 2 equal groups (lower low and higher low groups). Colorectal cancer incidence determined from follow-up was used. Cox’s proportional hazard model was employed to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs), adjusting for covariates. Results During 598 605 person-years of subject follow-up after baseline, we identified 806 colorectal cancer cases. HRs for the lower low versus the middle and high intake frequencies of vegetables and fruits at baseline were 0.95 (95% CI 0.77–1.16) and 1.08 (95% CI 0.90–1.29), respectively. During 125 980 person-years of subject follow-up after the interim survey, 197 colorectal cancer cases were identified. HRs for the low versus middle and high intake frequencies of vegetables and fruits in both baseline and interim surveys were 0.91 (95% CI 0.61–1.37) and 0.87 (95% CI 0.59–1.27), respectively. Conclusions Our results suggest that low intake and continued low intake of vegetables and fruits are not strongly associated with colorectal cancer risk.

Abstract
The elderly are known to have an inadequate immune response to influenza vaccine. Mekabu fucoidan (MF), a sulfated polysaccharide extracted from seaweed, was previously shown to have an immunomodulatory effect. We therefore investigated antibody production after influenza vaccination in elderly Japanese men and women with and without oral MF intake. A randomized, placebo-controlled, double-blind study was conducted with 70 volunteers >60 y of age. They were randomly assigned to 1 of 2 groups, consuming either MF (300 mg/d) or placebo for 4 wk, and then given a trivalent seasonal influenza vaccine. Serum was sampled at 5 and 20 wk after vaccination to measure the hemagglutination inhibition titer and natural killer cell activity. The MF group had higher antibody titers against all 3 strains contained in the seasonal influenza virus vaccine than the placebo group. Titers against the B/Brisbane/60/2008 (B) strain increased substantially more in the MF group than in the placebo group over the product consumption period. The immune response against B antigen met the European Union Licensure criteria regarding the geometric mean titer ratio in the MF group (2.4), but not in the placebo group (1.7). In the MF group, natural killer cell activity tended to increase from baseline 9 wk after MF intake (P = 0.08). However, in the placebo group no substantial increase was noted at 9 wk, and the activity decreased substantially from 9 to 24 wk. In the immunocompromised elderly, MF intake increased antibody production after vaccination, possibly preventing influenza epidemics.

Nutr Metab Cardiovasc Dis 2013; 23:519-527. [PMID: 22410388 DOI: 10.1016/j.numecd.2011.10.007] [Citation(s) in RCA: 52] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2010] [Revised: 09/06/2011] [Accepted: 10/21/2011] [Indexed: 11/25/2022]
Abstract
BACKGROUND AND AIMS Little evidence showed the association between dietary patterns and cardiovascular disease among Japanese. The objective of this study was to examine whether dietary patterns are associated with cardiovascular disease among middle-aged Japanese. METHODS AND RESULTS At baseline (1988-1990), 26,598 men and 37,439 women aged 40-79 years enrolled in the Japan Collaborative Cohort (JACC) Study. During the follow-up through 2003, 578 men and 499 women died from stroke, and 272 men and 207 women died from coronary heart disease. We identified three major dietary patterns, 'vegetable', 'animal food' and 'dairy product', by factor analysis for both sexes. The multivariable hazard ratio (HR) and 95% confidence intervals of mortality from total cardiovascular disease in the highest versus lowest quintiles of the vegetable pattern were 0.93 (0.78-1.13), p for trend=0.73 for men and 0.82 (0.67-1.00), p for trend=0.04 for women. The respective HRs of mortality from stroke in the highest versus lowest quintiles of the dairy product pattern were 0.65 (0.49-0.86), p for trend=0.01 for men and 0.70 (0.51-0.97), p for trend=0.02 for women, and those of total cardiovascular disease were 0.89 (0.74-1.08), p for trend=0.23 for men and 0.76 (0.61-0.94), p for trend=0.01 for women. The animal food pattern was not associated with mortality from stroke, coronary heart disease or total cardiovascular disease for either sex. CONCLUSION We found that 'vegetable' and 'dairy product' patterns were associated with lower morality from cardiovascular disease, while the 'animal food' pattern was not associated with mortality from cardiovascular disease among Japanese.

Abstract
Edible brown algae are used as major food material in Far East Asian countries, particularly in South Korea and Japan. They contain fermentable dietary fibers, alginic acid (uronic acid polymer) and laminaran (β-1,3-glucan), that are fermented into organic acids by intestinal bacteria. To clarify the effect of edible algae on the intestinal environment, the cecal microbiotas of rats fed diets containing no dietary fiber (control) or 2% (wt/wt) sodium alginate or laminaran for 2 weeks were analyzed using FLX amplicon pyrosequencing with bar-coded primers targeting the bacterial 16S rRNA gene. The most abundant phylum in all groups was Firmicutes. Specifically, Allobaculum was dominant in all diet groups. In addition, Bacteroides capillosus (37.1%) was abundant in the alginate group, while Clostridium ramosum (3.14%) and Parabacteroides distasonis (1.36%) were only detected in the laminaran group. Furthermore, rats fed alginate showed simplified microbiota phylotypes compared with others. With respect to cecal chemical compounds, laminaran increased cecal organic acid levels, particularly propionic acid. Alginate increased total cecal organic acids. Cecal putrefactive compounds, such as indole, H(2)S, and phenol, were decreased by both alginate and laminaran. These results indicate that edible brown algae can alter the intestinal environment, with fermentation by intestinal microbiota.

Abstract
The present systematic review was performed to assess differences in the worldwide consumption of functional foods. The Medline and Scopus databases were used to search the existing literature. A total of 23 studies that examined functional food consumption and included information on the country, gender, and age of participants were identified for inclusion. The studies investigated a variety of functional foods, and analysis of the findings indicates it is not possible to reach generalized conclusions about consumer choices regarding functional food consumption. Gender, age, level of education, and personal health status may each predict consumption of one or more functional foods. Further studies aimed at gaining a better understanding of the factors that influence consumption of functional foods are needed.

Abstract
This study investigated the preference and intake frequency of a list of 15 commonly available high sodium Malaysian foods/dishes, discretionary salt use, and their possible association with demographics, blood pressures and anthropometric measurements among 300 Malaysian university students (114 males, 186 females; 259 ethnic Chinese, 41 Indians; 220 lean, 80 overweight). French fries and instant soup noodle were found to be the most preferred and most frequently consumed salty food, respectively, while salted fish was least preferred and least frequently consumed. Males had a significantly higher intake frequency of at least 6 of the salty foods, but the preference of most salty foods was not significantly different between genders. Ethnic Chinese significantly preferred more and took more frequently traditional and conventional Malaysian foods like asam laksa (a Malaysian salty-sour-spicy noodle in fish stock), salted biscuits and salted vegetable, while Indians have more affinity and frequency towards eating salty Western foods. Body Mass Index was significantly negatively correlated with the intake frequency of canned/packet soup and salted fish while waist circumference was significantly positively correlated with the preference of instant noodle. Also, an increased preference of potato chips and intake frequency of salted biscuits seemed to lead to a decreased WHR. Other than these, all the other overweight/obesity indicators did not seem to fully correlate with the salty food preference and intake frequency. Nevertheless, the preference and intake frequency of asam laksa seemed to be significant negative predictors for blood pressures. Finally, increased preference and intake frequency of high sodium shrimp paste (belacan)-based foods like asam laksa and belacan fried rice seemed to discourage discretionary salt use. In conclusion, the preference and intake frequency of the high sodium belacan-based dish asam laksa seems to be a good predictor for ethnic difference, discretionary salt use and blood pressures.

Is cholecystectomy necessary after endoscopic treatment of bile duct stones in patients older than 80 years of age? J Gastroenterol 2012; 47:65-70.

Abstract
BACKGROUND AND AIMS Although patients with cholecystocholedocholithiasis are generally referred to cholecystectomy after endoscopic sphincterotomy (ES) and common bile duct clearance, we often have a conflict whether cholecystectomy is necessary in very elderly patients with comorbid diseases. The aim of this study is to assess whether cholecystectomy in very elderly patients is justified after ES. PATIENTS AND METHODS Patients with cholecystocholedocholithiasis who underwent ES and stone extraction and were followed-up for more than 10 years were retrospectively reviewed. We divided these patients into two groups: the elderly group (equal to or more than 80 years old) and young group (less than 80 years old) and compared late biliary complications and mortality. RESULTS The 10-year cumulative incidence of overall biliary complications was significantly lower in cholecystectomized patients than in patients with gallbladder in situ in the young group (7.5 vs. 21.7%, p = 0.0037), but not different in the elderly group (8.3 vs. 7.4%, p = 0.92). When each complication was evaluated separately, the rate of recurrent common bile duct stones (CBDS) was not different, but that of acute cholecystitis was significantly lower in the elderly group than in the young group (4.1 vs. 22.6%, p = 0.011). CONCLUSIONS In very elderly patients the incidence of acute cholecystitis is low even when the gallbladder is preserved after endoscopic treatment of CBDS, with a similar risk of CBDS recurrence. Thus, it may not be necessary to recommend cholecystectomy after ES for CBDS in very elderly patients.

Abstract
Japanese iodine intake from edible seaweeds is amongst the highest in the world. Predicting the type and amount of seaweed the Japanese consume is difficult due to day-to-day meal variation and dietary differences between generations and regions. In addition, iodine content varies considerably between seaweed species, with cooking and/or processing having an influence on iodine content. Due to all these factors, researchers frequently overestimate, or underestimate, Japanese iodine intake from seaweeds, which results in misleading and potentially dangerous diet and supplementation recommendations for people aiming to achieve the same health benefits seen by the Japanese. By combining information from dietary records, food surveys, urine iodine analysis (both spot and 24-hour samples) and seaweed iodine content, we estimate that the Japanese iodine intake--largely from seaweeds--averages 1,000-3,000 μg/day (1-3 mg/day).

Abstract
We used a database approach in developing a dish-based, semi-quantitative FFQ for Korean diet and cancer research. Cancer-related dietary factors (CRDF) recognised in the scientific community and dietary intake data from the 2001 Korean National Health and Nutrition Examination Survey and the 2002 Korean National Nutrition Survey by Season were used. The list of dishes (n 993) was those reported to be consumed by individuals over 30 years of age during all four seasons. The resulting 112-dish list was selected using contribution analyses and variability analyses to detect between-person variation for CRDF and non-CRDF nutrients. Variations of each dish were grouped into one dish for the final list of 112 dishes, which were then linked to the nutrient database. The final 112 dish items consisted of nine Korean staple dishes, including rice and noodles, twenty-five soups and stews, fifty-four side dishes, nine beverages, nine fruit dishes and six alcoholic beverages. The percentage coverages of energy, protein, fat, carbohydrate and alcohol intake in the selected 112 dishes were 82·4, 76·4, 68·9, 86·0 and 99·8 %, respectively. Dietary exposure to cancer-related Korean dietary factors can be assessed by this new dish-based, semi-quantitative FFQ. This new instrument can calculate the intake of CRDF along with non-CRDF nutrient intake for cancer research.

Abstract
CONTEXT The relationship between alcohol consumption and serum adiponectin levels has not been fully explored in an Asian population. OBJECTIVE Our goal was to determine whether alcohol consumption is associated with a change in adiponectin levels in a healthy Japanese population. DESIGN This was a cross-sectional study. SETTING Subjects were recruited from participants in a health check-up program. PARTICIPANTS This study included 2932 subjects (1306 men and 1626 women). MAIN OUTCOME MEASURES The effects of total weekly or daily volume of ethanol intake on serum adiponectin levels were evaluated. In addition, the correlation of clinical traits with serum adiponectin levels was examined. A multivariate regression model was used to control for possible confounding factors. RESULTS Alcohol consumption was weakly correlated with decreased serum adiponectin levels in men [Spearman's ordered correlation coefficient (rs=-0.141; P<0.001]; an even weaker correlation was seen in women (rs=-0.055; P=0.025). Multivariate analysis demonstrated that alcohol consumption was independently associated with hypoadiponectinemia. CONCLUSION In contrast to reports from the United States and Europe among White and Black subjects, our study demonstrated an inverse association between alcohol intake and serum adiponectin levels in Asian subjects, suggesting ethnic differences in the effects of alcohol consumption on serum adiponectin levels.

Abstract
OBJECTIVE The purpose of this study was to investigate the dietary iron intake and associated other dietary factors and clinical characteristics among a representative sample cohort of Japanese population. METHODS We obtained data from NIPPON DATA80 and 90 that were conducted with the National Nutrition Surveys in 1980 and in 1990. Then we estimated nutrient and food intakes of individuals in the National Nutrition Survey of 1980 and that of 1990, which were adjusted on the basis of data of the National Nutrition Survey of 1995. Finally, we analyzed data for the 10,422 participants (4585 men and 5837 women) in NIPPON DATA80 and 8342 participants (3488 men and 4854 women) in NIPPON DATA90 having dietary iron intake information. RESULTS In NIPPON DATA80 and 90, there was a significant relationship between the dietary iron intake and age for both men and women. Dietary protein intake was associated with iron intake where as dietary fat intake did not show any association. Regarding the minerals, significant relationships were observed between the different minerals and dietary iron intake. Apart from the food group of milk and dairy products, there were significant differences in other food groups according to quintiles of iron intakes for men and women. CONCLUSIONS We described the mean dietary iron intake and its relation with other dietary factors and clinical characteristics in Japanese adults as the baseline data in NIPPON DATA80 and in NIPPON DATA90.

Abstract
Objective The purpose of this study was to investigate the dietary calcium intake and associated other dietary factors among representative sample of Japanese general men and women. Methods Data was obtained by linking NIPPON DATA80 and 90 with the corresponding National Nutrition Surveys held in 1980 and 1990. We analyzed data for 10 422 subjects (4585 men and 5837 women) in NIPPON DATA80 and 8342 subjects (3488 men and 4854 women) in NIPPON DATA90. Calcium intake was calculated by age groups. Dietary calcium intake was classified into quintiles and physical, life-style, and dietary parameters were examined across the quintiles. Results For both men and women, calcium intake tended to be positively associated with age in NIPPON DATA80 and 90, and there were significant differences in estimated calcium intake between age groups. Calcium intake tended to be positively associated with age, protein, fat, saturated fat, vitamins A and C, sodium, potassium, and iron for men and women. Calcium intake also tended to be positively associated with intake of nuts, potatoes, sugar and sweeteners, soybeans and legumes, fruits, green and yellow vegetables, other vegetables, mushrooms, sea algae, fish and shellfish, eggs, and milk and dairy products for men and women. Conclusions The characteristics of calcium intake in Japanese people were able to be clarified by using the baseline data of NIPPON DATA and the National Nutrition Survey.

RESULTS In NIPPON DATA80 and 90 it was observed that there was a significant relationship between the dietary potassium intake and age for both men and women. Higher potassium intake was associated with higher age, intake of protein, iron, calcium, sodium, vitamins, and fiber. Regarding food groups, lower amount of dietary cereals, rice, flour, fats and oils were associated with higher dietary potassium for both men and women. On the other hand, higher intake of nuts, potatoes, soy beans, fruits, vegetables, mushrooms, sea algae, fish and shellfish were associated with higher dietary potassium. CONCLUSIONS We obtained the mean dietary potassium intake and its association with other dietary nutrient intake in Japanese adults as the baseline data in NIPPON DATA80 and in NIPPON DATA90.

Abstract
BACKGROUND Mortality from ischemic heart disease (IHD) has been showing a marked decline in Japan. The objective of this study was to clarify the effects of age, time period, and cohort on mortality from IHD in Japan from 1955 to 2000. METHODS AND RESULTS IHD death data from vital statistics and national population surveys were tabulated for 11 5-year age groups (from 30-34 to 80-84) and 10 quinquennial demographic profiles (from 1955 to 2000), to yield 20 5-year birth cohorts (mid-years from 1873 to 1968). The stratified Age-Period-Cohort model with 7 age classes shows: (1) mainly linear age trends for men with IHD, but effects below the linear age trends for women in middle-aged groups (40-74 years); (2) a decline in the effect of time period on IHD for both men and women from 1970 to 1990, and a sharp increase between 1990 and 1995 along with the change of the International Classification of Diseases Code; and (3) 2 patterns for both sexes for non-linear birth cohort effects, an increase (1873-1928) and a decrease (1928-1968) for men, and an increase (1873-1923) and a decrease (1923-1968) for women, with a stronger effect for women than for men born between 1893 and 1938, but the reverse for men and women born between 1938 and 1968. CONCLUSION Declining effects of birth cohort on mortality rates of IHD for young and middle-aged people suggest that mortality rates are likely to continue to decrease in Japan.

Abstract
BACKGROUND Although stroke mortality has been decreasing in Japan, in 2000 it was still the third leading cause of death among Japanese of either sex. Elucidation of stroke mortality trends among age, calendar year, and birth cohorts should improve stroke prevention efforts. The objective of this study was to clarify the age, period, and cohort effects on stroke mortality in Japan from 1960 to 2000 by using stratified age-period-cohort models with improved goodness of fit. METHODS Death and population from the Vital Statistics of Japan and the National Statistics Bureau, respectively, were tabulated among 12 age groups (30-34, 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65-69, 70-74, 75-79, 80-84, and 85-89) and 9 quinquennials (1960, 1965, 1970, 1975, 1980, 1985, 1990, 1995, and 2000), which yielded 20 birth cohorts (midyears of 1873, 1878, 1883, 1888, 1893, 1898, 1903, 1908, 1913, 1918, 1923, 1928, 1933, 1938, 1943, 1948, 1953, 1958, 1963, and 1968). A stratified model (age-periods-cohort model) with 7 age classes (30-44, 45-54, 55-64, 65-69, 70-74, 75-79, and 80-89 years) was applied under the assumption that the number of deaths has an extra-Poisson variation. RESULTS The stratified model showed that: (1) middle-aged groups (40-64 years in men and 40-59 years in women) had higher mortality than their linear age trends; (2) young (30-44 years) and middle-aged (45-64 years) groups showed different patterns than those of the elderly (65-89 years) age groups: the two younger groups had higher nonlinear period effects than their linear trends between 1970 and 1990, and the trend of decreasing began later (in 1975 in men and 1980 in women, respectively) than it did for the elderly (1970); and (3) the nonlinear cohort effects indicated 4 patterns in each sex, and the effects increased in post-1948 cohort in men and in post-1958 cohort in women. CONCLUSION Young and middle age (30-59 years) boosted the mortality, suggesting that this age range should be targeted for increased stroke prevention efforts.

Abstract
There is evidence showing a close relationship between diet and the occurrence of non-communicable chronic diseases. The present study assessed food consumption in a 2002/2004 cohort of young adults born in 1978/79 in Ribeirão Preto, SP, Brazil. The composition of the habitual diet consumed by a sample of 2063 individuals aged 23-25 years was analyzed using a validated semi-quantitative food frequency questionnaire based on studies of prevention of non-communicable chronic diseases. The Dietsys software was used for dietary calculations. In terms of WHO/2003 recommendations, there was a high mean daily consumption of energy from fat (consumption: 35.4%; recommendation: 15-30%), a low mean intake of energy from carbohydrates (47.5%; 55-75%) and a low mean consumption of total fibers (15.2 g; >25 g). Mean intake of energy from fatty acids (10%; <10%) and protein (15.6%; 10-15%) was within recommended limits. When compared to the recommendations of the food pyramid adapted to the Brazilian population, adequate intake was observed only regarding the meat group (consumption: 1.9 portions; recommended: 1-2). There was a low consumption of vegetables (2.9; 4-5), fruits (1.2; 3-5), breads (3.6; 6-9), and dairy products (1.7; 3), with excessive fat and sugar intake (5.7; 1-2). We conclude that the inadequate food consumption observed in this young population may be associated with the development of excess weight and may contribute to the triggering of non-communicable chronic diseases.

Abstract
The Japan Collaborative Cohort (JACC) Study was established in 1988-1990 and consisted of 46,465 men and 64,327 women observed until the end of 2003. A self-administered food frequency questionnaire was used as a baseline survey, and associations of dietary habits with the risk of ovarian cancer death were evaluated, taking into consideration age, menstrual and reproductive, anthropometric, and lifestyle factors. During the observation period, 77 women died of ovarian cancer. Hazard ratios for dietary factors were calculated by Cox's proportional hazards model. Being adjusted only for age, high intakes of dried or salted fish and Chinese cabbage were positively associated with the risk of ovarian cancer death, and the risk increased dose-dependently. In contrast, intake of soybean curd (tofu) was inversely associated with the risk. After being adjusted for age and potential confounding factors, the results regarding the intakes of dried or salted fish and Chinese cabbage did not change. However, the significance relating to the intake of soybean curd (tofu) was attenuated. From the results of this cohort study, it was suggested that high intakes of dried or salted fish and Chinese cabbage were potential risk factors of ovarian cancer death. In contrast, however, a high intake of soy bean curd (tofu) might have preventive effects against the risk.

Abstract
BACKGROUND Relationships between consumption of dairy products and death from various types of cancer are largely unknown. METHODS Between April 1992 and July 1995, a baseline survey was conducted for 11,349 residents in 12 communities in Japan, which included collection of demographic data and a self-administered food-frequency questionnaire inquiring about three dairy products: milk, butter and yogurt. The subjects were followed prospectively until 2002. Causes of death were identified using death certificates. Hazard ratios (HRs) and their 95% confidence intervals (CIs) for each dairy product were calculated using Cox's proportional hazard models. RESULTS Among eight common cancers, only deaths from hematopoietic neoplasm (n=14) were significantly associated with consumption of butter (HR=5.11, 95% CI: 1.40-18.62), though they exhibited a nearly-significant association with milk consumption (HR=3.17, 95% CI: 0.99-10.17), independent of age and sex. Consumption of milk and butter was significantly associated with non-lymphoma deaths (n=9) when adjusted for age and sex (HR=9.86, 95% CI: 1.23-79.19 for milk; and HR=10.04, 95% CI: 2.39-42.18 for butter). CONCLUSION The frequencies of butter consumption, and probably that of milk, were correlated with death from hematopoietic neoplasm, particularly from non-lymphomas.

Abstract
OBJECTIVES To evaluate the dietary fiber (DF) intake pattern among the Japanese general population. DESIGN We performed a dietary survey among the general population in northern Japan to evaluate the intake patterns. DF intake was calculated by substituting the DF content of each food in the Dietary Fiber Table for the intake of each food from this dietary survey. SUBJECTS Five hundred and seventy-seven subjects participated in the study, 198 men and 379 women. RESULTS In subjects with higher DF intakes the origins of the DF that were from all food groups, but with the notable exception of rice. The contribution of the seaweed group was of particular interest. From multiple regression analysis, as for food group, seaweeds showed the highest positive correlation with DF intake in both genders, followed by vegetables, pulses, fruits. On the other hand, rice showed the negative correlation with DF intake in both genders. As for life factor, body mass index showed the negative correlation with DF intake in women. CONCLUSION Seaweed, a typical Japanese food, was most related to the increase in DF intake for the Japanese general population, whereas rice, the Japanese staple, had a small influence on decreased DF intake.

Beneficial Effect of Oral Bisphosphonate Treatment on Bone Loss Induced by Chronic Administration of Furosemide without Alteration of Its Administration and Urinary Calcium Loss. Clin Pediatr Endocrinol 2006; 15:101-7.

Abstract
Bisphosphonate is widely used to treat patients with primary and secondary osteoporosis.
The chronic administration of furosemide is considered a risk factor for osteoporosis
mainly due to the increased urinary excretion of calcium, leading to a long-term negative
balance of calcium. We describe two patients with mild heart failure who took furosemide
for more than 5 yr and developed hyperparathyroidism and lumbago associated with low bone
mineral density. Their serum levels of intact parathyroid hormone and bone mineral density
(BMD) of the lumbar spine (L2-L4) were 180.8 and 144.3 pg/ml, and 71% and 80% of the mean
of healthy women, respectively. The oral administration of alendronate or risedronate was
effective for lumbago and improved BMD, although the urinary excretion of calcium and
hyperparathyroidism were not changed. For the medical treatment of lumbago and decreased
bone mass secondary to the long-term administration of furosemide, bisphosphonate is
proposed when the dose of furosemide cannot be reduced. However, it may be important to
give sufficient calcium and vitamin D to patients to improve secondary
hyperparathyroidism.
