The association of fatty acid composition with insulin resistance and type 2 diabetes has been reported in Western populations, but there is limited evidence of this association among the Japanese, whose populace consume large amounts of fish. To test the hypothesis that high palmitic, palmitoleic, and dihomo-γ-linolenic acids and low levels of linoleic and(More)
OBJECTIVE To examine the association between the consumption of green tea, coffee and caffeine and depressive symptoms. DESIGN Cross-sectional study. Consumption of green tea and coffee was ascertained with a validated dietary questionnaire and the amount of caffeine intake was estimated from these beverages. Depressive symptoms were measured using the(More)
OBJECTIVE Higher levels of physical activity have been consistently associated with a decreased risk of colon cancer, but not rectal cancer, in Western populations. The present study systematically evaluated epidemiologic evidence on the association between physical activity and colorectal cancer risk among the Japanese population. METHODS Original data(More)
OBJECTIVE Although intake of minerals has been suggested to be beneficial against depression, epidemiologic data from free-living settings are limited. The aim of this study was to determine the cross-sectional associations between the intake of magnesium, calcium, iron, and zinc and the prevalence of depressive symptoms in Japanese employees. METHODS(More)
OBJECTIVE The association between meat consumption and colorectal cancer remains inconsistent among Asians. The present study systematically evaluated and meta-analyzed epidemiologic studies on the association between consumption of total and specific meats and colorectal cancer risk among Japanese. METHODS Original data were obtained from MEDLINE(More)
BACKGROUND Circulating high-sensitivity C-reactive protein (CRP) is a good marker of chronic low-grade inflammation. The few studies that have addressed the relationship between coffee consumption and CRP concentrations report inconsistent findings. The authors of this study examined the relationship between coffee and green tea consumption and serum(More)
Beneficial effects of dairy consumption in preventing obesity and metabolic syndrome have been suggested, but the association between dairy intake and insulin resistance (IR) is not clear. To test the hypothesis that higher dairy consumption is associated with lower insulin resistance, the authors investigated the association between dairy intake (taking(More)
OBJECTIVE Higher vitamin B status has been linked to a lower risk for cancer, but the underlying mechanism remains elusive. The aim of the present study was to examine the association of pyridoxal, folate, and homocysteine (Hcy) with urinary 8-hydroxydeoxyguanosine (8-OHdG), a marker of oxidative DNA damage. METHODS The participants were 500 employees(More)
OBJECTIVE Acid-base status has been suggested to influence blood pressure, but there is a paucity of epidemiologic evidence linking dietary acid load to hypertension. We examined cross-sectionally the association between dietary acid load and hypertension in a Japanese working population. METHODS Data were derived from health surveys from 2028 employees,(More)
Long working hours have been associated with an increased risk of cardiovascular disease, but its relationship with hypertension remains unclear. The objective of this study is to examine the relationship between overtime and presence of hypertension using data from a large-scale multi-company study in Japan. Participants were 52 365 workers of four(More)
