La description
Volunteers will be invited to appear in a 12-hour fast to measure glucose levels, glycated hemoglobin and to perform the glucose tolerance test, in addition to an individual interview to confirm eligibility according to the inclusion and exclusion criteria. The collection of blood and the glycemic curves will be carried out next to a Laboratory of Clinical Analyzes, commercial, based in the city of Araraquara.
The sample number took into account variances on glycated hemoglobin with a type I error α = 0.05 and a type II error β = 0.2 (80% power) (Mohammad, 2015). The minimum sample size considering an approximately 20% dropout rate, should have 20 individuals per group.
In order to ensure adequate nutrition for the nutritional and energetic needs of volunteers, an individual food plan shall be prescribed, calculated according to the DRI equations. The volunteer will be asked to complete the Food Record for three days at the 3rd, 5th, 7th, 9th and 11th week. Data analysis of energy intake, macronutrients and micronutrients will be performed through the DietBox® . The anthropometric measurements will be performed before the intervention and in the 3rd, 5th, 7th, 9th and 11th week by Nutritionist. Four samples of 30mL of fasting blood each will be obtained before the intervention, in the 4th, 8th and 12th week in the Laboratory of Clinical Analyzes. The blood will be centrifuged to obtain the serum, which will be frozen at -80 ° C until subsequent biochemical analyzes.
Normality and homogeneity will be evaluated by Shapiro-Wilk test and Levine tests, respectively. The T test will be used to compare baseline time between groups. The two-way repeated-measures ANOVA will be used to compare changes within and between the eriocitrin and control groups over the 12-week period. P significant at ≤ 0.05.
