Bioactive lipids play an important role in human health and their benefits are linked to their chemical nature; for example, medium-chain fatty acids can have an important contribution to body weight management. This work aimed to test a strategy to enhance the quality profile and gastrointestinal tract resistance of previously developed vegetable oil-functionalized yogurts and further probe the biological potential of functionalized yogurts. Fortification with coconut and avocado vegetable oils led to increased nutritional value through an increase in essential fatty acids content, particularly in yogurts with vegetable oil bigels. One of the main problems with bioactive fatty acids fortification is their poor stability during in vitro digestion and consequently poor bioavailability. Despite this, the digested samples decreased lipid accumulation in Hep G2 and 3T3-L1 cells Functionalized yogurts were also responsible for high improvements in adiponectin secretion (35% for COY, 46% for CBY, 53% for AOY, and 48% ABY) compared with control yogurt. Moreover, in the inflammatory model, a reduction between 30% (for control yogurt) and 70% (for CBY) was observed for IL-6 secretion in LPS-stimulated cells. Considering these results, yogurt’s fortification with vegetable oils can be a viable alternative strategy to be scaled up for obesity management.

Background: Obesity leads to chronic low-grade inflammation, promoting detrimental effects on bone. The consumption of virgin coconut oil (VCO) is associated with benefits related to meta-inflammation. We evaluated the effect of VCO supplementation on osteopenia promoted by diet-induced obesity in mice. Methods: Male BALB/c mice were fed a control (C) or highly refined carbohydrate-containing (HC) diet for eight weeks. After that, the HC diet group was supplemented with three doses of VCO for four weeks. Results: The HC diet increased the adiposity and leptin levels associated with augmented systemic inflammatory cells improved with VCO supplementation. The HC diet reduced the trabecular bone in the tibia, lumbar vertebrae, distal and proximal femur, as well as the bone mineral density of the femur and alveolar bone. The VCO supplementation reverted bone osteopenia by increasing the trabecular bone in different sites and improving femur and alveolar bone microarchitecture. Although the reduced number of osteoblasts in the alveolar bone of the HC diet group was not significantly enhanced by VCO supplementation, the reduced Alp expression in the HC diet group was enhanced in the VCO group. These beneficial effects were associated with lowering the Rankl/Opg ratio. Conclusion: VCO supplementation might be an effective strategy to attenuate bone osteopenic effects induced by obesity.
