RESUMO
This study examined the effect of Vitis vinifera grape skin ACH09 extract (ACH09) on metabolic disorders and oxidative stress in adult offspring of rats fed a high-fat diet (HF) during lactation. Four groups of female rats were fed: control diet (7% fat); ACH09 (7% fat + 200 mg·kg·d ACH09 orally); HF (24% fat); HF+ ACH09 (24% fat + 200 mg·kg·d ACH09 orally) during lactation. From weaning onward, all female offspring were fed a control diet and killed when they were 90 or 180 days old. Systolic blood pressure was increased in adult offspring of HF-fed dams, and ACH09 prevented hypertension. Increased adiposity, plasma triglyceride, glucose levels, and insulin resistance were observed in offspring from both ages, and these changes were reversed by ACH09. The plasma oxidative damage assessed by malondialdehyde levels was increased, and nitrite levels decreased in the HF group of both ages, which were reversed by ACH09. In addition, ACH09 restored the decreased plasma and mesenteric artery antioxidant activities of superoxide dismutase, catalase, and glutathione peroxidase in the HF group. In conclusion, ACH09 protected normally fed offspring of HF-fed dams during lactation from phenotypic and metabolic characteristics of metabolic syndrome providing an alternative nutritional resource for the prevention of metabolic syndrome.
