ABSTRACT To evaluate the associations with chronic disease risk and mortality of the consequences of bean-free diets in Taiwanese adults with regard to gender.
A sub-sample of the National Health Interview Survey (NHIS) in 2001 agreed to physical examination in the subsequent year. This group then took part in the Taiwanese Survey of Hyperglycaemia, Hyperlipidaemia and Hypertension (TwSHHH) in 2002.
Individual records were linked to the eventual death files from 2002 to 2008.
Up to the end of 2008, a total of 2820 men and 2950 women were tracked by death registry over the 6·8 years of follow-up.
Among 38,077 person-years, an average follow-up 6·5 years, 225 all-cause deaths were identified. Generalized linear models showed beans to be favourable for metabolic syndrome (other than for fasting glucose) in men; in women, beans were favourable for waist circumference and HbA1c. Cumulative logistic regression models for the effect of a bean-free diet on metabolic syndrome scores according to the Taiwanese-modified National Cholesterol Education Program-Adult Treatment Panel III (NCEP-tw) gave adjusted odds ratios of 1·83 in men and 1·45 in women. Cox regression models for the bean-free diet showed an increased hazard ratio for all-cause mortality among women (1·98, 95% CI 1·03, 3·81) but not men (1·28, 95% CI 0·76, 2·16).
A bean-free diet may play a role in developing the metabolic syndrome in both genders, and is a significant predictor of all-cause mortality in Taiwanese women but not men.

    • "These findings provide additional support for the increased education and awareness needed regarding dry bean associated health properties, particularly in clinical nutrition and dietetics program curriculums. Additionally, the relationship between longevity and increased dry bean consumption may not only be associated with the fiber contents as other nutritional components and phytochemicals may work synergistically for health promotion and disease prevention [34-36].

    ABSTRACT: Introduction: Emerging evidence supports that increased consumption of dry beans (Phaseolus vulgaris L.) reduces both the incidence and recurrence of adenomatous polyps or precancerous growths. Navy beans have been studied for dietary colorectal cancer (CRC) chemoprevention in animal models. Our main objectives were to assess the feasibility of increased navy bean consumption in adults with and without history of CRC and to achieve intake amounts associated with chemoprevention. Methods: Seven meals and six snacks were developed for both the absence and inclusion of cooked navy bean powder (35grams/day). Sixteen healthy adults (7 non-cancer and 9 CRC survivors) completed the placebo-controlled, randomized, single-blinded dietary intervention trial. Participants consumed one study-provided meal and snack daily for 28 days, which accounted for approximately one-third of their total recommended caloric intake (meals = 202-483 kcal and snacks = 194-401 kcal). Participants also recorded three-day dietary food logs each week. Results: The addition of 35g of cooked navy bean powder (NBP) into foods provided 5-8% daily caloric intake. The compliance to the meal and snack intervention ranged from 89-100%. Non-cancer participants in the NBP group had a significant decrease in total caloric intake after week 4 (p≤0.0001). CRC survivors in the NBP group significantly increased total fiber intake by week 4 (p≤0.0001). Conclusions: NBP are feasible to include in meals for increased total fiber intake and for consuming the amount that is associated with CRC chemoprevention outcomes. These findings warrant further evaluation of NBP consumption in clinical nutrition trials for CRC control and prevention.

    ABSTRACT: Early detection and interventions for metabolic syndrome (MetS) are the most cost-effective methods for preventing many chronic diseases. There have been discordant findings in various countries due to different genetics and lifestyles. The goal of this study was to investigate the association of MetS with parental diseases, a Chinese-style diet, and rural-urban regional differences with a large-scale epidemiological survey in Taiwan. Data were obtained from the Taiwanese Survey on Hypertension, Hyperglycemia, and Hyperlipidemia (TwSHHH), a cross-sectional population-based study with multistage stratified random sampling conducted by the Taiwan Bureau of Health Promotion in 2002. Public health nurses visited homes to conduct the survey, including blood drawing and an interview. Multiple logistic regression analysis was used for exploring the factors associated with MetS. A total of 6591 people completed data for analysis. Our results revealed that older age, male sex, and maternal diabetes or hypertension, were significantly associated with MetS. Eating poultry with skin and fat and eating a bean-free diet may be associated with a higher risk of MetS. People who exercised regularly and the residents of the Taipei metropolitan area had a lower prevalence of MetS. As a result, people with maternal diabetes or hypertension should pay attention to their cardiovascular health and prevention of MetS. We suggest that eating skinless and low-fat poultry, eating more beans, and exercising regularly, may decrease the risk of MetS. We should make an effort to advocate for health promotion, including lifestyle modification, especially among the high-risk population and among residents in rural areas with limited medical resources.

    ABSTRACT: Background A mass Japanese encephalitis (JE) vaccination program targeting children was launched in Taiwan in 1968, and the number of pediatric JE cases substantially decreased thereafter. The aim of this study was to elucidate the long-term trend of JE incidence, and to investigate the age-specific seroprevalence of JE-neutralizing antibodies. Methodology/Principal Findings A total of 2,948 laboratory-confirmed JE cases that occurred between 1966 and 2012 were analyzed using a mandatory notification system managed by the Centers for Disease Control, Taiwan. A total of 6,594 randomly-sampled serum specimens obtained in a nationwide population-based survey in 2002 were analyzed to estimate the seroprevalence of JE-neutralizing antibodies in the general population. The average annual JE incidence rate of the group aged 30 years and older was 0.167 cases per 100,000 people between 2001 and 2012, which was higher than the 0.052 cases per 100,000 people among those aged under 30 years. These seroepidemiological findings indicate that the cohort born between 1963 and 1975, who generally received two or three doses of the vaccine and were administered the last booster dose more than 20 years ago, exhibited the lowest positive rate of JE-neutralizing antibodies (54%). The highest and second highest antibody rates were observed, respectively, in the oldest unvaccinated cohort (86%) and in the youngest cohort born between 1981 and 1986, who received four doses 10–15 years ago (74%). Conclusion/Significance Over the past decade, the main age group of the confirmed JE cases in Taiwan shifted from young children to adults over 30 years of age. People who were born between 1963 and 1975 exhibited the lowest seroprevalence of JE-neutralizing antibodies. Thus, the key issue for JE control in Taiwan is to reduce adult JE cases through a cost-effective analysis of various immunization strategies.
