ABSTRACT Objective: This study aimed to compare the influence of a high carbohydrate meal versus high-fat meal on the oxidation of substrates during an exercise incremental test. Materials and methods: Ten untrained male subjects underwent two days of the protocol. Randomly, they received a high carbohydrate meal or a high-fat meal, receiving the other one in the next protocol. On both days, they performed an incremental treadmill test, with heart rate and maximal oxygen consumption to estimate the oxidation of […]

OBJECTIVE: To investigate the association between carbohydrate intakes and ?-cell function (HOMA-?) in Japanese-Brazilians with impaired glucose tolerance (IGT). METHODS: Dietary intakes were assessed by a validated food frequency questionnaire in a cross-sectional survey carried out in 2000. The associations between diet and HOMA-? were verified in 270 newly diagnosed IGT in multiple linear regression models. RESULTS: The mean (SD) age was 58 (11) years and the mean HOMA-? was 65 (47). The glycemic load was inversely associated with HOMA-?, […]
