We compared the cross-sectional association of alcohol consumption with blood pressure in 810 Japanese men (JM) living in Tokyo and 946 white men (WM) living in New York. Mean systolic (JM and WM, p < 0.001) and diastolic blood pressure (JM, p < 0.002; WM, p < 0.001) were associated with alcohol consumption in both groups. Compared to abstainers, the heaviest drinkers had the highest systolic (JM, p = 0.001; WM, p < 0.01) and diastolic (JM, p < 0.002; WM, p < 0.05) blood pressures. The relation of blood pressure to alcohol intake was J-shaped in the Americans, but linear in the Japanese. Exploratory analyses revealed that the J-shape may have been due to under-reporting of heavy alcohol ingestion by American abstainers. When abstainers were excluded, the relationships were similar in both the American and Japanese. The positive association between blood pressure and alcohol consumption persisted after adjustment for age, cigarette smoking, use of antihypertensive medications, body mass index, heart rate, abdominal skinfold thickness, hematocrit, fasting blood glucose, serum uric acid levels and urinary sodium/potassium ratio. Alcohol use was also related to prevalence of hypertension. These findings confirm the presence of an independent association between alcohol intake and blood pressure in both JM and WM and suggest that, despite differences in the metabolism of alcohol, the relation of alcohol consumption to blood pressure is similar in both nationalities. 相似文献

Longitudinal study of soy food intake and blood pressure among middle-aged and elderly Chinese women
Yang G Shu XO Jin F Zhang X Li HL Li Q Gao YT Zheng W 《The American journal of clinical nutrition》2005,81(5):1012-1017
BACKGROUND: Several small-scale clinical trials have suggested a potential beneficial effect of short-term soy consumption on blood pressure (BP). Data are scanty on long-term effects of the usual intake of soy foods on BP in general populations. OBJECTIVE: Our aim was to examine the association between usual intake of soy foods and BP. DESIGN: The usual intake of soy foods was assessed at baseline, and BP was measured 2-3 y after the baseline survey among 45 694 participants of the Shanghai Women's Health Study aged 40-70 y who had no history of hypertension, diabetes, or cardiovascular disease at recruitment. Multiple regression models were used to estimate mean differences in BP associated with various intakes of soy foods. RESULTS: Soy protein intake was inversely associated with both systolic BP (P for trend = 0.01) and diastolic BP (P for trend = 0.009) after adjustment for age, body mass index, and lifestyle and other dietary factors. The adjusted mean systolic BP was 1.9 mm Hg lower (95% CI: -3.0, -0.8 mm Hg) and the diastolic BP was 0.9 mm Hg lower (-1.6, -0.2 mm Hg) in women who consumed > or =25 g soy protein/d than in women consuming <2.5 g/d. The inverse associations became stronger with increasing age (P for interaction < 0.05 for both BPs). Among women >60 y old, the corresponding differences were -4.9 mm Hg (95% CI: -8.0, -1.9 mm Hg) for systolic BP and -2.2 mm Hg (95% CI: -3.8, -0.6 mm Hg) for diastolic BP. CONCLUSION: Usual intake of soy foods was inversely associated with both systolic and diastolic BPs, particularly among elderly women. 相似文献

Kentaro Murakami Satoshi Sasaki Kazuhiro Uenishi 《Nutrition (Burbank, Los Angeles County, Calif.)》2013,29(11-12):1315-1320
ObjectiveLittle is known about the relation of modifiable dietary factors to circulating adiponectin concentrations, particularly in young adults and non-Western populations. The aim of this study was to determine the association between macronutrient and food intake and serum adiponectin concentration in a group of young Japanese women.MethodsThis cross-sectional study included 1047 female Japanese dietetic students aged 18 to 22 y. Using a validated, self-administered, comprehensive diet history questionnaire, we assessed intake of nutrients (protein, total fat, saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids, carbohydrates, and dietary fiber) and foods (rice, bread, noodles, potatoes, confectioneries, fats and oils, pulses, fish and shellfish, meats, eggs, dairy products, vegetables, fruits, coffee, green and oolong tea, black tea, and soft drinks) and glycemic index and load. Fasting blood samples were collected and serum adiponectin concentrations were measured. Adjustment was made for survey year, region, municipality level, current smoking, current alcohol drinking, physical activity, body mass index, energy intake, and intakes of other nutrients or foods.ResultsAfter adjustment for potential confounding factors, none of the nutrients examined was a significant determinant of serum adiponectin concentration. There was no association for glycemic index or load. Coffee was the only food significantly and independently associated with serum adiponectin concentration. Mean (SE) values of serum adiponectin concentration for each quartile of coffee intake were 12.4 (0.2), 12.4 (0.5), 12.5 (0.3), and 13.2 (0.3) μg/mL, respectively (P for trend = 0.04).ConclusionIn a group of young Japanese women, higher coffee intake was independently associated with higher serum adiponectin concentration. 相似文献

ObjectivesMilk fat globule membrane (MFGM) found in buttermilk is rich in unique bioactive proteins. Several studies suggest that MFGM proteins possess biological activities such as cholesterol-lowering, antiviral, antibacterial, and anticancer properties, but data in humans are lacking. Furthermore, to our knowledge, no study has yet investigated the antihypertensive potential of MFGM proteins from buttermilk. The aim of this study was to investigate the effects of buttermilk consumption on blood pressure and on markers of the renin–angiotensin–aldosterone (RAS) system in humans.MethodsMen and women (N = 34) with plasma low-density lipoprotein cholesterol < 5 mmol/L and normal blood pressure (< 140 mm Hg) were recruited in this randomized, double-blind, placebo-controlled, crossover study. Their diets were supplemented with 45 g/d of buttermilk and with 45 g/d of a macro-/micronutrient-matched placebo in random order (4 wk for each diet).ResultsButtermilk consumption significantly reduced systolic blood pressure (−2.6 mm Hg; P = 0.009), mean arterial blood pressure (−1.7 mm Hg; P = 0.015), and plasma levels of the angiotensin I-converting enzyme (−10.9%; P = 0.003) compared with the placebo, but had no effect on plasma concentrations of angiotensin II and aldosterone.ConclusionShort-term buttermilk consumption reduces blood pressure in normotensive individuals. 相似文献

We examined the cross‐sectional relationship of soy product intake to serum concentrations of estradiol (E2) and sex hormone‐binding globulin (SHBG) in 50 healthy premenopausal Japanese women. Intakes of soy products and various nutrients were estimated through a semiquantitative food‐frequency questionnaire. Blood samples were drawn from each subject on Days 11 and22 of her menstrual cycle. The intake of soy products was inversely correlated with E2 on Days 11 and 22 of the cycle after controlling for age, body mass index, cycle length, and intakes of total energy, fat, and crude fiber (r = ‐0.23, p = 0.08 and r = —0.32, p = 0.04, respectively). No significant correlation was observed between soy product intake and SHBG. There was a tendency for the intake of individual soy foods such as tofu and miso to be inversely correlated with E2 on Days 11 and 22 of the menstrual cycle. Miso intake was inversely significantly correlated with SHBG on Day 22 of the cycle (r = ‐0.36, p = 0.02). If the observed association is causal, our results suggest that the consumption of soy products lowers the risk of developing breast cancer risk modifying estrogen metabolism. 相似文献

Dietary variety within food groups: association with energy intake and body fatness in men and women
McCrory MA Fuss PJ McCallum JE Yao M Vinken AG Hays NP Roberts SB 《The American journal of clinical nutrition》1999,69(3):440-447
BACKGROUND: Short-term experimental studies suggest that dietary variety may influence body fatness but no long-term human studies have been reported. OBJECTIVE: The purpose of this study was to determine whether dietary variety within food groups influences energy intake and body fatness. DESIGN: Seventy-one healthy men and women (aged 20-80 y), who provided accurate reports of dietary intake and completed a body-composition assessment, were studied. RESULTS: Dietary variety was positively associated with energy intake within each of 10 food groups (r = 0.27-0.56, P < 0.05). In multiple regression analysis with age and sex controlled for, dietary variety of sweets, snacks, condiments, entrées, and carbohydrates (as a group) was positively associated with body fatness (partial r = 0.38, P = 0.001) whereas variety from vegetables was negatively associated (partial r = -0.31, P = 0.01) (R2 = 0.46, P < 0.0001). In separate models, both a variety ratio (variety of vegetables/variety of sweets, snacks, condiments, entrées, and carbohydrates) and percentage dietary fat were significant predictors of body fatness (controlled for age and sex, partial r = -0.39 and 0.31, respectively, P < 0.01). However, dietary fat was no longer significantly associated with body fatness when the variety ratio and dietary fat were included in the same model. CONCLUSIONS: Our data, coupled with those of previous short-term studies, suggest that a high variety of sweets, snacks, condiments, entrées, and carbohydrates coupled with a low variety of vegetables promotes long-term increases in energy intake and body fatness. These findings may help explain the rising prevalence of obesity. 相似文献

Objectives
The aim of this study was to examine the relationship between subjective evaluations of the frequency of salty food intake and both urinary sodium excretion and blood pressure (BP) in a middle-aged population.Methods
Urinary sodium and creatinine concentrations in a spot sample and brachial BP were measured in 419 subjects (mean age 37 ± 9 years, 385 men) during a health examination at a company in Kanagawa, Japan, 2011. Twenty-four-hour urinary sodium excretion was estimated from sodium and creatinine concentrations in the spot sample. The subjects were asked about the frequency of salty food intake on a self-reported questionnaire, choosing their answer from ‘seldom’, ‘sometimes’, or ‘always’ based on their own subjective evaluation. The amount of daily salt intake was converted from 24-h urinary sodium excretion.Results
The prevalence of high salt intake, defined as greater than the daily average salt intake of Japanese according to the National Health and Nutrition Survey in 2010, gradually increased from the ‘seldom’ to the ‘sometimes’, and then ‘always’ categories (10.3, 13.4, and 24.0 %, respectively; P = 0.013 for trend). The 24-h urinary sodium excretion among these groups also tended to be different; however, the differences did not reach a significantly significant level (145 ± 41, 152 ± 34, and 160 ± 40 mEq/day, respectively; P = 0.076). Both systolic and diastolic BP were similar among the groups.Conclusions
Although some of our findings raise the possibility of a relationship between a subjective evaluation of the frequency of salty food intake and urinary sodium excretion, further studies are needed to confirm the relationship. In contrast, no relationship with BP was found. 相似文献15.

The cross-sectional relationships of soy product intake and serum testosterone, estrone, estradiol, sex hormone-binding globulin, and dihydrotestosterone were examined in 69 Japanese men. Soy product intake was estimated from a semiquantitative food frequency questionnaire. Serum estradiol concentration was significantly inversely correlated with soy product intake (r = -0.32, p = 0.009), and serum estrone concentration was nonsignificantly inversely correlated with soy product intake (r = -0.24, p = 0.05) after controlling for age, body mass index, smoking status, and ethanol intake. Total and free testosterone concentrations were inversely correlated with soy product intake after controlling for the covariates, but these correlations were of border line significance (r = -0.25, p = 0.05 and r = -0.25, p = 0.06, respectively). Similar correlations were observed for these hormones with isoflavone intake from soy products. The data suggest that soy product intake may be associated with the endogenous hormone levels in Japanese men. 相似文献

The mean daily sodium intake was determined for 33 normotensive subjects by analysis of a 7 day 24 h urine collection. The intake range was 1.75–5.77 g Na/day with an intra-individual standard deviation of 1.08 g Na and an inter-individual standard deviation of 0.80 g Na giving a ratio of intra-to inter-individual variance of 1.82, 79% of the subjects were correctly classified into the approapriate tertile for sodium intake after the 7 day collection. The intake range for potassium was 1.54 to 4.2 g/day.No relationship was observed between blood pressure and sodium or potassium intake. Salivary sodium levels (both stimulated and unstimulated) were positiviely correlated with sodium excretion of the day preceding saliva collection. 相似文献
