Abstract

The influence of chia (Salvia hispanica L.) flour and oil on glucose metabolism (GM) in insulin resistant (IR) Wistar rats and the effect of chia hydrolyzed phenolics extract (CHPE) on GM in IR HepG2 cells were evaluated. In vivo study: animals were divided into four groups: AIN-93M, high-fat and high-fructose (HFHF), HFHF with chia flour (14.7%) or chia oil (4%). In vitro study: IR HepG2 cells were treated with CHPE (80 ppm). In vivo, chia flour and oil reduced adiposity and increased AMPK mRNA. Chia oil improved glucose tolerance, increased AKT1[pS473] protein level, mRNA of insulin receptor, FOXO1 and glycolysis enzymes. In vitro, CHPE decreased gluconeogenesis enzymes mRNA. Chia flour and oil decreased adiposity, but only chia oil was able to improve glucose tolerance and restore energy fuel system in liver of rats fed HFHF diet. CHPE decreased mRNA levels of gluconeogenesis enzymes.
