Habitual dietary intake is a complex behavior that may have both biological and nonbiological bases. We estimated the contribution of genetic and environmental influences on dietary intake in a large population-based sample of healthy twins. Data originated from a cross-sectional study of 600 male and female healthy twin pairs with self-reported food consumption frequency using a validated ques...

Age-related hearing loss is a frequent disability in older adults and nutrition could play a role in the development of this condition. Carbohydrate nutrition [including dietary glycemic index (GI) and load (GL)] may be linked to hearing loss. We aimed to determine the association between carbohydrate nutrition (including mean dietary GI and GL, and the dietary intakes of carbohydrate and sugar...

BACKGROUND Glycemic index (GI) and glycemic load (GL) have been associated with coronary heart disease (CHD) risk in some but not all cohort studies. We therefore assessed the association of GI and GL with CHD risk in prospective cohorts. METHODS AND RESULTS We searched MEDLINE, EMBASE, and CINAHL (through April 5, 2012) and identified all prospective cohorts assessing associations of GI and ...

BACKGROUND Studies on obesity and glycemic index (GI) or glycemic load (GL) have had inconsistent results, perhaps in part because of underreporting or to heterogeneous dietary patterns across food cultures. OBJECTIVES We examined associations between body mass index (BMI) and GI or GL in a Mediterranean population, accounting for underreporting. We also constructed dietary factors related to...

BACKGROUND Studies on the association of stroke risk to dietary glycemic index (GI) and glycemic load (GL) have produced contrasting results. OBJECTIVE To investigate the relation of dietary GI and GL to stroke risk in the large EPIC-Italy cohort (EPICOR) recruited from widely dispersed geographic areas of Italy. DESIGN We studied 44099 participants (13,646 men and 30,453 women) who complet...

Different carbohydrate diets have been administrated to diabetic patients to evaluate the glycemic response, while Poor-controlled diabetes is increasing world wide. To investigate the role of an alternative carbohydrate diet on glycemic control, we explored the effect of a low glycemic load (Low GL)-high fat diet on glycemic response and also glycated hemoglobin (HbA1c) of poor-controlled diab...

Insulin and insulin-like growth factor-I (IGF-I) are associated with increased risk of breast cancer in several studies. Circulating concentrations of insulin increase with dietary consumption of high glycemic index foods, which, in turn, may influence IGF-I levels or activity, but the relevance of such dietary patterns for breast cancer risk is unclear. We investigated whether consumption of c...

The role of dietary carbohydrates in weight loss has received considerable attention in light of the current obesity epidemic. The authors investigated the association of body mass index (weight (kg)/height (m)(2)) with dietary intake of carbohydrates and with measures of the induced glycemic response, using data from an observational study of 572 healthy adults in central Massachusetts. Anthro...

OBJECTIVE To identify nutritional factors that affected the glycemic control of the studied population. SUBJECTS AND METHODS One hundred forty-six children and adolescents, aged 7 to 19 years, followed-up at the Division of Pediatric Endocrinology of the Hospital das Clínicas da Universidade Federal de Minas Gerais participated in the study.The diet of each participant was evaluated by means ...
