In contrast , fasting plasma glucose , fasting plasma insulin as well as the homeostasis model assessment of insulin resistance were not affected by the amounts of MUFA in the dietary protocol s. Conclusions : In summary , this systematic review found that high MUFA diets appear to be effective in reducing HbA1c , and therefore , should be recommended in the dietary regimes of T2D
Background / Aims : In 2008 , the American Diabetes Association recommended low-carbohydrate or low-fat diets for weight management in patients with established type 2 diabetes ( T2D ) , while the amount of monounsaturated fatty acids ( MUFA ) was not specified .
This systematic review focused on the effects of diets high in MUFA versus diets low in MUFA on important risk factors of T2D ( i.e. plasma glucose , insulin , homeostasis model assessment of insulin resistance and glycosylated haemoglobin , HbA1c ) .
Dietary Monounsaturated Fatty Acids but not Saturated Fatty Acids Preserve the Insulin Signaling Pathway via IRS-1/PI3K in Rat Skeletal Muscle
Saturated fatty acids ( SFA ) and monounsaturated fatty acids ( MUFA ) show different effects on the development of insulin resistance . In this study , we compared the effect of dietary SFA and MUFA on the insulin signaling pathway in the skeletal muscle of a type 2 diabetic animal model . Twenty-nine-week-old male Otsuka Long-Evans Tokushima fatty ( OLETF ) rats were r and omly divided into three groups and fed one of the following diets for 3 weeks ; a normal chow diet , an SFA ( lard oil ) enriched or a MUFA ( olive oil ) enriched high-fat diet . The vastus lateralis muscle was used for analyses . Insulin tolerance test showed improved insulin sensitivity in rats fed the MUFA diet , as compared to those fed the SFA diet ( p < 0.001 ) . The SFA diet reduced IRS-1 expression and phosphorylated PI3 K levels in skeletal muscle , as compared with a chow diet ( p < 0.001 , respectively ) . On the contrary , muscle IRS-2 expression and phosphorylated ERK1/2 was significantly increased in rats fed the SFA diet ( p < 0.001 , respectively ) . Membrane translocation of glucose transporter type 4 decreased in the skeletal muscle of rats fed the SFA diet , as compared to those fed a chow diet ( p < 0.001 ) . These changes in insulin signaling pathway in skeletal muscle were not observed in rats fed the MUFA diet . In conclusion , the beneficial effect of dietary MUFA on insulin sensitivity is associated with a conserved IRS-1/PI3 K insulin signaling pathway which was altered by dietary SFA
