Intake of high–glycemic index (GI) food has been postulated to reduce satiety, resulting in an increased total energy intake and reduced access to body fat as fuel. Thus, we hypothesize that high dietary GI and glycemic load (GL) are associated with an increased prevalence of obesity in the Korean population. Dietary GI and GL were calculated for 933 Korean men and women based on dietary intake assessed by food frequency questionnaires and using a GI table developed from published GI databases in a cross-sectional design. Mean differences in dietary GL and carbohydrate intake between obese and nonobese men were statistically significant after adjusting for covariates (P = .027 and .021, respectively). High dietary GL and carbohydrate intake were negatively associated with the prevalence of obesity among men in a multivariate-adjusted logistic regression model (P for trend = .026 and .036, respectively). Statistically significant effects of dietary GI and GL on the prevalence of obesity among women were observed in a generalized linear model (P = .002 and .042, respectively) and a logistic regression model (P for trend < .001 and = .007, respectively), after adjusting for covariates. Women with higher dietary GI and GL were more likely to be obese, a result consistent with our hypothesis. However, an inverse association for dietary GL and carbohydrate and prevalence of obesity was found in men, suggesting that mechanisms contributing to the prevalence of obesity between sexes may be different. 相似文献

Metabolic diseases in China have been on the rise during recent decades. To investigate dietary glycaemic load (GL) and its correlation with the prevalence of metabolic diseases in hospitalised Chinese adults, we analysed the total energy and macronutrient intakes in 1040 patients. Dietary GL was calculated based upon glycaemic index (GI), carbohydrate content and daily intake of individual foods. Dietary patterns at different dietary GL levels and the distribution of dietary GL were analysed in patients from the internal medical departments v. those from surgical departments. Height and weight were measured using a standardised protocol. The present study results demonstrated that in hospitalised adults, 95·5?% of dietary GL came from cereals. Average GL was higher in male patients than in female patients, and was higher in patients from surgical departments than in patients from medical departments. Patients with lower dietary GL consumed inadequate carbohydrates and excessive fats, and therefore had a higher prevalence of overweight and obesity. Dietary GL analysis may be helpful to nutrition assessment and rational diet intervention in hospitalised Chinese patients. 相似文献

Low glycemic index (GI) and glycemic load (GL) diets are effective for glycemic control (GC) associated with a carbohydrate-controlled meal plan. However, whether GI and GL peaks are related to GC is unknown. Objective: To compare the daily GI (DGI)/GL (DGL) and average GI (AvGI)/GL (AvGL) of meals (accounting for peaks) related to GC markers (GCM) in Brazilian adolescents. Methods: A representative national school-based (public/private) sample of students without diabetes, 12–17 years of age, was evaluated. Food intake was based on a 24 h recall. The models for complex cluster sampling were adjusted (sex, sexual maturation, age, and physical activity). Results: Of 35,737 students, 74% were from public schools, 60% girls, 17% overweight, and 8% obese. The minimum DGI and DGL were observed at lunch, with higher values at night. Fasting insulin was 1.5 times higher in overweight/obese (OW) girls, and 1.7 times higher in OW boys than in normal-weight (NW) girls. The same trend was observed for the homeostatic model assessment for insulin resistance (HOMA-IR) (OW = 2.82 vs. NW = 1.84 in girls; OW = 2.66 vs. NW = 1.54 in boys; p < 0.05). The daily and average metrics were greater for NW adolescents. Glycosylated hemoglobin was not associated with these metrics, except for AvGL. Insulin and HOMA-IR were associated with all metrics in NW adolescents, with greater coefficients associated with AvGL. Among overweight/obese adolescents, only GI metrics were associated (β = 0.23; AvGI and insulin) and appeared to have the best association with GCM. Conclusions: Among NW adolescents, GL is a better measure of carbohydrate quality, but for those with overweight/obesity, carbohydrate consumption is more associated with GC, probably because they eat/report small amounts of carbohydrates. 相似文献

BACKGROUND: Diets high in carbohydrates may result in chronically elevated insulin concentrations and may affect breast cancer risk by stimulation of insulin receptors or through insulin-like growth factor I (IGF-I)-mediated mitogenesis. Insulin response to carbohydrate intake is increased in insulin-resistant states such as obesity. OBJECTIVE: We sought to evaluate carbohydrate intake, glycemic index (GI), and glycemic load (GL) and subsequent overall and hormone-receptor-defined breast cancer risk among postmenopausal women. DESIGN: A prospective cohort analysis of dietary carbohydrate and fiber intakes was conducted among 62 739 postmenopausal women from the E3N French study who had completed a validated dietary history questionnaire in 1993. During a 9-y period, 1812 cases of pathology-confirmed breast cancer were documented through follow-up questionnaires. Nutrients were categorized into quartiles and energy-adjusted with the regression-residual method. Cox model-derived relative risks (RRs) were adjusted for known determinants in breast cancer. RESULTS: Dietary carbohydrate and fiber intakes were not associated with overall breast cancer risk. Among overweight women, we observed an association between GI and breast cancer (RR(Q1-Q4): 1.35; 95% CI: 1.00, 1.82; P for trend = 0.04). For women in the highest category of waist circumference, the RR(Q1-Q4) was 1.28 (95% CI: 0.98, 1.67; P for trend = 0.10) for carbohydrates, 1.35 (95% CI: 1.04, 1.75; P for trend = 0.01) for GI, and 1.37 (95% CI: 1.05, 1.77; P for trend = 0.003) for GL. We also observed a direct association between carbohydrate intake, GL, and estrogen receptor-negative breast cancer risk. CONCLUSIONS: Rapidly absorbed carbohydrates are associated with postmenopausal breast cancer risk among overweight women and women with large waist circumference. Carbohydrate intake may also be associated with estrogen receptor-negative breast cancer. 相似文献

Changes in the quality and quantity of carbohydrate foods may compromise nutrient intake in women with gestational diabetes mellitus (GDM). We hypothesized that glycemic index, glycemic load (GL), carbohydrate intake, grains, and cereal product consumption would be associated with nutrient adequacy. Eighty-two women with GDM (61% of Asian background, 34% whites) completed a 3-day food record following their routine group nutrition education session. Nutrient intakes were compared to Nutrient Reference Values (NRV) for Australia and New Zealand. Nutrient intake across energy-adjusted tertiles of glycemic index, GL, carbohydrate intake, and intake of grains and cereal products were assessed. The majority of women (66%-99%) did not meet the NRV for fiber, folate, vitamin D, iodine, and iron, and exceeded NRV for saturated fat and sodium. Higher dietary GL was associated with lower intakes of total, monounsaturated, and polyunsaturated fat; vitamin E; and potassium (all P < .001). Higher grain intake was not significantly associated with intake of any micronutrients. In Australian women with GDM, high dietary GL predicts greater risk of poor nutrition. 相似文献

OBJECTIVES: High glycemic index (GI) carbohydrates may increase brain serotonin, which in turn acts to alleviate premenstrual symptoms, because, although the main determinant of brain serotonin concentration is a high plasma ratio of tryptophan to other large neutral amino acids, a high-GI diet has been shown to increase this ratio. In this observational cross-sectional study, we investigated associations between dietary GI and other dietary carbohydrates and premenstrual symptoms. METHODS: Subjects were 640 female Japanese dietetic students 18-22 y of age. Dietary carbohydrates were assessed using a validated, self-administered, comprehensive diet history questionnaire. Menstrual cycle symptoms were assessed using the retrospective version of the Moos Menstrual Distress Questionnaire (MDQ). Independent associations of dietary GI and glycemic load and intake of available carbohydrate and dietary fiber with the MDQ total score and subscale scores (pain, concentration, behavioral change, autonomic reactions, water retention, and negative affect) in the premenstrual phase (expressed as percentages relative to those in the intermenstrual phase) were examined. RESULTS: Dietary GI was independently inversely associated with total MDQ score in the premenstrual phase (P for trend = 0.02). Dietary GI also showed independent and inverse associations with several MDQ subscale scores in the premenstrual phase, including concentration, autonomic reactions, and water retention (P for trend < 0.05). Conversely, dietary glycemic load and intake of available carbohydrate and dietary fiber were not associated with any of the MDQ scores in the premenstrual phase. CONCLUSION: Dietary GI was independently associated with decreased premenstrual symptoms in a group of young Japanese women. 相似文献
