Objetivo
Avaliar os efeitos da suplementação de goma guar no controle metabólico e índice de massa corporal (IMC) em pacientes portadores de diabetes do tipo 2.
Métodos
Um total de dezessete participantes (doze mulheres e cinco homens) receberam a suplementação diária de dez gramas do suplemento de fibra durante três meses. Alterações no IMC e nos parâmetros bioquímicos (glicemia de jejum, hemoglobina glicada (HbA1c), colesterol plasmático total e triglicérides) foram avaliadas no início e ao final do estudo.
Resultados
Não foram verificadas alterações nos valores médios de IMC (p=0,770), glicemia de jejum (p=0,09) ou triglicérides (p=0,06). No entanto, foi observado aumento significativo (p<0,001) dos níveis de HbA1c após a ingestão dos suplementos de goma guar. Análise posterior indicou que cinco participantes que tiveram valores médios de glicemia de jejum e de HbA1c mais altos tiveram uma redução significativa (p=0,03) da glicemia de jejum ao final do estudo. Uma redução significativa (p<0,001) na concentração de colesterol total foi observada após os três meses de suplementação com a goma guar.
Conclusão
A suplementação dietética de goma guar (10g/dia) a pacientes portadores de diabetes tipo 2, com sobrepeso, proporcionando uma ingestão total de fibra próxima de 20g por dia, não foi efetiva para redução espontânea do peso corporal. Os efeitos da goma guar sobre o controle metabólico da glicose foram inconclusivos, mas mostrou ser uma estratégia dietética efetiva na redução dos níveis de colesterol sangüíneo.
