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.

Abstract Title: 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. Abstract Source: Mol Nutr Food Res. 2010 Jan 28. Epub 2010 Jan 28. 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.

Randomized controlled trial of the effect of phytosterols-enriched low-fat milk on lipid profile in Chinese.

Related Articles Randomized controlled trial of the effect of phytosterols-enriched low-fat milk on lipid profile in Chinese. Sci Rep. 2017 01 24;7:41084 Authors: Cheung CL, Ho DK, Sing CW, Tsoi MF, Cheng VK, Lee GK, Ho YN, Cheung BM Abstract Phytosterols found naturally in plants are known to reduce cholesterol absorption in the gut. The traditional southern Chinese diet typically contains many vegetables and not much meat, and there is high prevalence of lactose intolerance in Chinese; we therefore aimed to test if phytosterols-enriched milk is effective in lowering serum LDL-cholesterol in Chinese. Two hundred and twenty-one participants (41 men and 180 women; age 24-79) without cholesterol-lowering drugs or diabetes mellitus were randomized to daily intake of phytosterols-enriched low-fat milk which contained 1.5 g phytosterols per day (N = 110) or a conventional low-fat milk (N = 111) for three weeks. Fasting bloods were taken before and at the end of the study for the measurement of lipid and glucose profile. Physical examination was also performed. Comparing treatment with control, treatment group had significant decrease in serum LDL-cholesterol level (9.5 ± 2.0%; p < 0.0001). Phytosterols intake also decreased total cholesterol (P < 0.0001) and diastolic blood pressure (P = 0.01). Consumption of a phytosterols-enriched low-fat milk led to a significant fall in LDL-cholesterol, total cholesterol, and diastolic blood pressure in Chinese. This can be recommended as part of a healthy diet for people. (ClinicalTrials.gov identifier: NCT02541201; Date of registration: 26 Aug 2015). PMID: 28117400 [PubMed - indexed for MEDLINE]
