Dissertação (Mestrado em Nutrição e Saúde) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/5620Overweight and obesity are associated with excessive food intake, due to changes in the productions of gastrointestinal hormones productions. Objectives: To evaluated the effect of a herbal extract derived from native species of South America on food intake, acylated ghrelin concentrations and peptide similar to glucagon 1. Material and methods: A randomized, blind, placebo-controlled, crossover design methodology, with intervention in two days with an interval (washout) seven days, consisted of 20 overweight women. Three capsules a mix of herbal medicines were administered, containing 112 mg of yerba mate, guarana 95 mg and 36 mg of damiana, or three placebo capsules containing 100 mg of lactose. The herbal extract was administered 15 minutes before a standardized breakfast (494.50 kcal, carbohydrates 52.67%, 12.91% protein and 34.5% lipid) and a standard lunch (632.05 kcal, 61, 67% carbohydrates, 16.97% protein and 21.44% lipid) for all patients. Food not eaten by the participants was weighed to evaluated food intake. Blood samples were collected at baseline and on days 45, 60, 90, 150, 210 minutes after breakfast in the morning and lunch for determination of plasma glucose concentrations, acylated ghrelin and peptide similar to glucagon 1. To compare the differences of the mean energy food intake and macronutrient was performed paired t-test, for the behavior of hormones was performed ANOVA and was calculated area under the curve and to determine the differences between the areas was performed Student's t test. Results: In the supplemented group, there was significant reduction in energy intake at lunch and macronutrients in both meals (p <0.05). The acylated ghrelin concentrations were lower after breakfast (p <0.05) and glucagon-like peptide 1 were higher (p <0.05) after breakfast in the supplemented group. Conclusion: Supplementation with herbal mix reduced energy intake and macronutrients by the modulating hormones glucagon-like 1 and acylated ghrelin in overweight and obesity women.application/pdfAcesso AbertoObesidadeHormônios gastrointestinaisPeptídeo semelhante ao glucagon 1Grelina aciladaErva-mateGuaranáDamianaObesityGastrointestinal hormonesPeptide similar to glucagon 1Acylated ghrelinYerba mateGuaranaDamianaCIENCIAS DA SAUDE::NUTRICAODissertação
