“…In Japan, 15% to 31% of vitamin E is obtained from green and yellow vegetables, 13% to 27% from fish and shellfish, and 11% to 21% from vegetable oil, whereas in Europe or the United States, 33% comes from oil and fats and 17% from cereals and doughnuts. 8,17 Our study has several limitations. First, vitamin intakes were estimated on the basis of a limited number of foods (nϭ40) in the self-administered FFQ without options for food portion size.…”

“…4 -7 Vegetables are a primary dietary source of vitamins A and E, and fruit is a primary dietary source of vitamin C for the Japanese. 8 However, whether this protective effect is in fact caused by antioxidant vitamins A, E, or C remains unclear. Observational studies and clinical trials in Europe and the United States have reported on associations of antioxidant vitamin with reduced mortality or morbidity from cardiovascular disease.…”

Background and Purpose-Only a few reports have dealt with the association of antioxidant vitamin intakes with mortality or morbidity from cardiovascular disease in Asia. We investigated the relation of dietary vitamins A, E, and C intake with mortality from cardiovascular disease for Japanese men and women. Methods-The subjects were 23 119 men and 35 611 women aged 40 to 79 years without a history of cardiovascular disease or cancer who responded to the food frequency questionnaire as part of the Japan Collaborative Cohort Study for Cancer Risk (JACC) Study. They were followed up for a median period of 16.5 years. Hazard ratios were calculated per quintile of dietary vitamins A, E, and C intake by using Cox proportional hazard model. Results-During the 859 962 person-year follow-up, there were 2690 deaths (1343 men and 1347 women) from cardiovascular disease, comprising 1227 (607 men and 620 women) from stroke and 557 (311 men and 246 women) from coronary heart disease. The multivariable hazard ratios (95% CI) associated with the highest versus lowest quintiles of vitamin C intake were 0.70 (0.54 to 0.92) for total stroke, 0.63 (0.41 to 0.97) for coronary heart disease, and 0.79 (0.66 to 0.94) for total cardiovascular disease for women, but the inverse associations observed were weak and did not reach statistical significance for men. No significant association was observed between vitamins A or E intake and risk of mortality for either men or women. Conclusions-Vitamin C intake is inversely associated with mortality from cardiovascular disease for Japanese women. (Stroke. 2011;42:1665-1672.)

“…Some population studies demonstrated negative associations for adults and in neonatal development (8, 21), but no significant association was found in child populations (12, 13, 21). The Japanese traditionally consume less oil/fat and fewer milk/dairy products (17) than Western populations, and these are major sources of vitamin E. To our knowledge, only one case–control study of Japanese children involving a small sample size showed no significant association between serum vitamin E and asthma (11), whereas eczema has not been studied. α‐Tocopherol could participate directly in several defense mechanisms related to atopic diseases via antioxidant and immune‐enhancing effects.…”

“…This discrepancy is also observed in adult populations (15, 16) and indicates that the Japanese diet has different vegetable/fruit intake pattern as compared to the Western diet. Furthermore, although decreased consumption of vegetables is one of the causes for the increasing prevalence of atopic diseases in Western countries, vegetable intake by the Japanese has been increasing in the past decades (17), in spite of a similar trend of increasing prevalence of atopy in Japan (18). Japanese as well as Mediterranean diets provide protection against chronic diseases, but the Japanese have a much lower intake of oils/fats including olive oil (19), which may influence the bioavailability of fat‐soluble nutrients including carotenoids and vitamin E.…”

The present study assessed whether serum carotenoids and tocopherols are associated with atopic diseases (eczema and asthma) in 10- and 13-yr-olds in a Japanese community. Of 2796 students attending schools in Shunan, Japan, in 2006, 396 students were randomly selected for this study using nested case-control design. Atopic diseases and dietary food intake were assessed using self-administered questionnaires, and serum antioxidants were analyzed using high-performance liquid chromatography. We found no associations between serum carotenoids and atopic diseases. However, odds ratios (OR)s for the third and fourth quartiles of serum alpha-tocopherol with atopic eczema were 0.33 (95% confidence interval: 0.15-0.73) and 0.36 (0.14-0.89), respectively, and the trend was negatively significant (P(trend) = 0.048). We did not find a significant association for asthma. In conclusion, serum alpha-tocopherol was negatively associated with the prevalence of eczema. Serum carotenoids did not show definitive protective effects in Japanese youth.

“…The intakes of vegetables, fruits, fish and shellfish are regarded as the key for the prevention of cardiovascular disease, as is mentioned in the Japan Atherosclerosis Society (JAS) guidelines [ 25 ]. Vegetables and fruits are a primary dietary source of antioxidant vitamins such as vitamin A, E and C, dietary fiber and folic acid which reported on associations with reduced mortality from cardiovascular disease [ 6 , 7 , 27 , 30 – 32 ]. And fish and shellfish are rich in B-complex vitamins such as vitamin B6 and vitamin B12, and n-3PUFAs which were also reported to have a preventive efficacy of cardiovascular disease in several cohort studies [ 33 – 36 ].…”

Relationship between atherosclerosis and occlusal support of natural teeth with mediating effect of atheroprotective nutrients: From the SONIC study

et al. 2017

Whereas most of studies investigating relationship between oral health and atherosclerosis have focused on periodontitis, very few of them were examined about occlusal status of natural teeth which possibly influence dietary habit. The primary aim of this cross-sectional study was to investigate the association between the occlusal support of posterior teeth and the prevalence of atherosclerosis in community-dwelling septuagenarians. Also, the second aim was to test the hypothesis that the intake of key nutrients for atherosclerosis prevention would have a mediating effect on the relationship between the occlusal status and atherosclerosis. The study population included 468 community-dwelling dentate persons aged 69–71 years recruited from the local residential registration in Japan. Participants were divided into three groups, according to the number of occlusal support zones (OSZ) in the posterior area: Complete (four OSZ), Moderate (three or two OSZ), and Collapsed (one or no OSZ). Dietary intakes were assessed using a brief-type self-administered diet history questionnaire. Atherosclerosis was defined as carotid intima-media thickness ≧1.10 mm by using carotid ultrasonography test. The logistic or linear regression model was used in multivariate analysis to assess relationship between occlusal status and atherosclerosis, and the mediating effect of key nutrients within the relationship. Multivariable analysis showed a significant association between occlusal status and atherosclerosis (odds ratio for Collapsed group to Complete group: 1.87; 95% CI: 1.45–2.41), independent of periodontal status (odds ratio: 2.01, 95%CI: 1.46–2.78). Fish and shellfish, vitamin B6 and n-3PUFAs were significantly related to both of occlusal status and atherosclerosis, and also was indicated a mediating effect on the association between occlusal status and atherosclerosis. This study implied that, within the limitation of the cross-sectional study design, the reduced posterior occlusion was related to the increased prevalence of atherosclerosis via the decline of key dietary intakes among Japanese community-dwelling dentate individuals.
