Obesity frequently associates with chronic inflammatory diseases, including type 2 diabetes. In this study, a combination of a protein hydrolysate, LCPUFAs and a probiotic strain was investigated on the development of high fat diet ‐induced diabetic risk factors and complications in LDLr‐/‐.Leiden mice. Male LDLr‐/‐.Leiden mice at 12 wks of age received a high fat diet (HFD) for 21 wks with or without a combination of an extensive casein hydrolysate, docosahexaenoic acid (DHA), arachidonic acid (ARA), and Lactobacillus Rhamnosus GG (LGG). Both HFD and intervention diet were isocaloric and casein from HFD was replaced with casein hydrolysate in the test diets. The addition of DHA/ARA in the test diets was controlled for in the HFD. Moreover, a PBS gavage control group was included to control for potential effects of LGG gavage. There were significant beneficial effects of the hydrolysate/ARA/DHA/LGG composition versus the HFD control group including reduced body weight gain, lower plasma levels of insulin, cholesterol and triglycerides, lower systemic inflammation, improved adipose tissue quality and mass, and improved kidney and liver function. In a follow up study, evaluating the individual components of the test formulation, some of the outcomes were attributable to the hydrolysate or LGG. A combination of an extensive casein hydrolysate, ARA, DHA and LGG reduces the detrimental effects of HFD on the development of obesity and its metabolic complications. Main risk factors for the metabolic syndrome such as adipose tissue and chronic inflammation were markedly reduced which could provide a rationale for the beneficial effects observed.
