Impact of improving eating habits and rosmarinic acid supplementation on rat vascular and neuronal system in the metabolic syndrome model.

Impact of improving eating habits and rosmarinic acid supplementation on rat vascular and neuronal system in the metabolic syndrome model. Br J Nutr. 2020 Aug 20;:1-30 Authors: Michalikova D, Tyukos Kaprinay B, Brnoliakova Z, Sasvariova M, Krenek P, Babiak E, Frimmel K, Bittner Fialova S, Stankovicova T, Sotnikova R, Gasparova Z Abstract Decreasing high fat and high carbohydrate intake, together with the administration of natural bioactive drugs is assumed to have a protective effect in the prevention and amelioration of metabolic syndrome (MetS). The aim of the study was to evaluate effects of diet improvement and/or a phenolic compound - rosmarinic acid (RA) administration (100 mg/kg/day) on metabolic as well as functional changes of vessels and hippocampus caused by MetS-like conditions. MetS-like conditions were induced by high-fat-fructose diet (HFFD) in Prague hereditary hypertriacylglycerolemic rats. The effect of diet improvement and RA administration was studied using biochemical and functional measurements. Consumption of HFFD by hypertriacylglycerolemic rats resulted in the development of conditions like MetS. The fat and fructose restriction from the diet led to amelioration of basic indicators of metabolic state in rats fed HFFD and to amendment parameters of glucose-tolerance test and reduction of the IL-1β serum levels. Moreover, aortic endothelial function was improved with an impact on blood pressure. The functional...
