Dietary intake of isoflavones and polyunsaturated fatty acids associated with lung function, breathlessness and the prevalence of chronic obstructive pulmonary disease: possible protective effect of traditional Japanese diet.

PMID: 20112297 Abstract Author(s): Fumi Hirayama, Andy H Lee, Colin W Binns, Naoko Hiramatsu, Mitsuru Mori, Koichi Nishimura Abstract: The Japanese diet is high in soy products and fish. A case-control study was conducted in Japan to investigate the relationship between dietary intake of isoflavones and fatty acids and lung function, breathlessness and chronic obstructive pulmonary disease (COPD). A total of 278 referred patients aged 50-75 years with COPD diagnosed within the past 4 years, and 340 community-based controls were assessed for respiratory symptoms and undertook spirometric measurements of lung function. A validated food frequency questionnaire was administered face-to-face to obtain information on habitual food consumption. Dietary intakes of isoflavones and fatty acids were derived from the Japanese food composition tables. The COPD patients had significantly lower habitual intakes of isoflavones (genistein and daidzein) and polyunsaturated fatty acids (PUFA; both omega-3 and omega-6) than control subjects. Lung function measures were found to be positively associated with isoflavones and PUFA intake. Substantial reductions in prevalence of COPD and breathlessness were observed for isoflavones, the respective adjusted odds ratio being 0.36 (95% confidence interval 0.19-0.68) and 0.60 (95% confidence interval 0.33-1.10) for the highest versus lowest levels of total isoflavone intake. The corresponding tests for linear trend were significant. High intakes of PUFA and omega-6 fatty acids (derived from foods excluding oils and fats as seasonings) also appeared to reduce the risks of COPD and breathlessness symptom, but no evidence of association was found for other types of fatty acids. The study provided evidence of possible protective effect of traditional Japanese diet against tobacco carcinogens. Article Published Date : Jan 28, 2010

Dietary patterns associated with functional constipation among Japanese women aged 18 to 20 years: a cross-sectional study. 📎

Abstract Title: Dietary patterns associated with functional constipation among Japanese women aged 18 to 20 years: a cross-sectional study. Abstract Source: J Nutr Sci Vitaminol (Tokyo). 2007 Jun;53(3):232-8. PMID: 17874828 Abstract Author(s): Hitomi Okubo, Satoshi Sasaki, Kentaro Murakami, Mi Kyung Kim, Yoshiko Takahashi, Yoko Hosoi, Mami Itabashi, Abstract: Although several nutrients and foods have been suggested to be preventive for constipation, all previous studies have examined a single nutrient or food in each analysis. In contrast, analysis of dietary patterns may provide new insights into the influence of diet on functional constipation. We conducted a cross-sectional examination of the association between dietary pattern and functional constipation in 3,770 Japanese female dietetic course students aged 18-20 y from 53 institutions in Japan. Diet was assessed with a validated self-administered diet history questionnaire with 148 food items, from which 30 food groups were created and entered into a factor analysis. Functional constipation was defined using the Rome I criteria, which has previously been used in several epidemiologic studies on constipation. The prevalence of functional constipation was 26.0% (n=979). Four dietary patterns were identified: (1) "Healthy", (2) "Japanese traditional", (3) "Western," and 4) "Coffee and dairy products." After adjustment for several confounding factors, the "Japanese traditional" pattern, characterized by a high intake of rice, miso soup, and soy products and a low intake of bread and confectionaries, was associated with a significantly lower prevalence of functional constipation. In comparison with the lowest quintile, the multivariate adjusted odds ratio (95% confidence interval) was 0.52 (0.41-0.66) in the highest quintile (p for trend<0.0001). Other dietary patterns were not associated with functional constipation. The Japanese traditional dietary pattern, characterized by a high intake of rice and a low intake of bread and confectionaries, may be beneficial in preventing functional constipation in young Japanese women.

Promotive effect of Bofutsushosan (Fangfengtongshengsan) on lipid and cholesterol excretion in feces in mice treated with a high-fat diet.

Related Articles Promotive effect of Bofutsushosan (Fangfengtongshengsan) on lipid and cholesterol excretion in feces in mice treated with a high-fat diet. J Ethnopharmacol. 2018 Jun 28;220:1-8 Authors: Akaki J, Tachi S, Nakamura N, Arai T, Yamasaki H, Inoue M, Makino T Abstract ETHNOPHARMACOLOGICAL RELEVANCE: Bofutsushosan (fangfengtongshengsan in Chinese, BTS) is a formula in traditional Japanese Kampo medicine and Chinese medicine comprising 18 crude drugs that is used for treating obesity and metabolic syndrome. AIM OF THE STUDY: We evaluated the promotive effects of BTS on lipid and cholesterol elimination in mice. MATERIALS AND METHODS: Mice were reared with a high-fat diet containing boiled water extract of BTS for 30 days, and their biochemical parameters as well as the weight and lipid content of feces were measured. We also measured cholesterol uptake into Caco-2 cells cultured with or without BTS extract. RESULTS: The body weight and amounts of visceral fat and subcutaneous fat on day 28; the weights of epididymal, perirenal, and mesenteric fat; and the serum concentrations of triglyceride, glucose, and hemoglobin A1c on day 30 were significantly lower in the BTS extract-treated groups than in the control in a dose-dependent manner. The amounts of lipid and cholesterol in the feces collected from day 6-23 were significantly greater than in the control. When Caco-2 cells were incubated with BTS extract, the uptake of cholesterol into cells was significantly reduced in a concentration-dependent manner. Among the components of BTS, the methanol extracts of Platycodi Radix and Zingiberis Rhizoma contribute but the extracts of Ephedrae Herba and Rhei Rhizoma counteract the suppressive effect of BTS on cholesterol uptake into Caco-2 cells. CONCLUSIONS: BTS has beneficial effects on obesity and metabolic syndrome, and its mechanisms of action include the promotion of lipid elimination and the inhibition of cholesterol absorption in the intestine.
