Description
Summary:There is a growing interest in functional foods that, apart from their nutritional function, bring health benefits, contributing to wellbeing and/or reducing the risk of certain diseases. The objective of this study was to evaluate the functional effect of a soybean and rice beverage on the ponderal and nutritional parameters and on the lipid and glycemic metabolisms of male hamsters. Four groups of 8 animals were used: Control (commercial feed), C (commercial feed with added cholesterol), B (commercial feed plus beverage) and CB (commercial feed plus cholesterol and beverage). The food efficiency coefficient was equivalent for all the groups. The weight of the liver was on average 28% heavier in groups C and CB than in the other groups, indicating cholesterol deposition in this organ. Although there was no significant difference, the concentrations of total cholesterol and of its fractions (LDL and HDL) and of the triglycerides, were lower in group CB than in group C, showing a possible benefic effect of the beverage. The blood glucose concentration did not differ significantly (p<0.05). É crescente o interesse por alimentos que, além da função de nutrir, trazem benefícios à saúde, contribuindo para o bem-estar e/ou reduzindo o risco de algumas doenças. Objetivou-se, neste estudo, avaliar o efeito funcional de bebida de soja e arroz nos parâmetros ponderais e nutricionais e no metabolismo lipídico e glicêmico de hamsters machos. Foram utilizados 4 grupos de 8 animais: Controle (ração comercial), C (ração comercial acrescida de colesterol), B (ração comercial e bebida) e CB (ração comercial acrescida de colesterol e bebida). O coeficiente de eficiência alimentar foi equivalente em todos os grupos. O peso do fígado dos grupos C e CB apresentou-se em média 28% maior que os demais, indicando deposição de colesterol nesse órgão. Embora não havendo diferença significativa, as concentrações de colesterol total e suas frações (LDL e HDL) e de triacilglicerídeos foram menores no grupo CB comparadas ao grupo C, mostrando possível efeito benéfico da bebida. A concentração de glicose no sangue não diferiu significativamente (p<0,05).
