Abstract

PURPOSE: To evaluate whether the prolonged consumption of flaxseed minimize the factors that trigger MS in healthy rats. METHODS: Pregnant rats were divided immediately after delivery into two groups during the lactation period, a control group (CG) receiving casein-based diet with 17% of protein, and a Flaxseed group (FG) with casein-based diet plus 25% of flaxseed. At weaning, 12 offspring of each group continued to receive the same feed but with 10% of protein up to 200 days old. RESULTS: FG showed a significant reduction in body weight (p=0.001), total cholesterol levels (p<0.0001), triglycerides (p=0.0001), and glucose (p=0.001). CONCLUSION: The flaxseed alters the indicators related to development of metabolic syndrome, because it has beneficial effects on lipids and glucose profiles and prevents the excess of body weight gain.OBJETIVO: Avaliar se o consumo prolongado de linhaça pode minimizar os fatores que desencadeiam síndrome metabólica em ratos fêmeas saudáveis. MÉTODOS: Ratos fêmeas grávidas foram distribuidas após o parto em dois grupos durante o período de lactação: grupo controle (GC) recebendo dieta à base de caseína com 17% de proteína, e um grupo Linhaça (GL), com dieta à base de caseína adicionada de 25% de semente de linhaça. Ao desmame, 12 filhotes de cada grupo continuaram a receber as rações citadas acima, porém com 10% de proteína, até os 200 dias de vida. RESULTADOS: O GL mostrou uma redução significativa do peso corporal (p=0,001), no colesterol total (p<0,0001), triglicerídeos (p=0,0001) e na glicemia (p=0,001). CONCLUSÃO: A linhaça altera os indicadores relacionados ao desenvolvimento da síndrome metabólica por ter efeitos benéficos no perfil lipídico e glicêmico, e previne o excesso de ganho de peso corporal.
