We hypothesized that the consumption of chia ( L.) flour (CF) and chia oil (CO) improves metabolic disorders in the liver of Wistar rats () fed a high-fat and high-fructose (HFHF) diet. The animals were fed a HFHF diet ( = 30) or AIN93-M standard diet ( = 10) for eight weeks. After this period, the animals fed HFHF were divided into three groups ( = 10): HFHF diet, HFHF plus 14.7% of CF, and HFHF plus 4% of CO. Histological and biochemical analyses, gene expression, protein levels related to inflammation, and oxidative stress were evaluated in the liver. The HFHF diet caused lipogenesis, liver steatosis, oxidative stress, and inflammation in the animals. The CF and CO intake increased the liver total antioxidant capacity and superoxide dismutase, decreased nitric oxide levels and liver steatosis. Furthermore, the CF and CO led to the upregulation of and , respectively, whereas CF downregulated . CO intake decreased blood glucose, triglycerides, and the animals' body weight. Chia did not show effects on mitigating liver pro-inflammatory status, which it may indicate occurs later. The addition of chia into an unbalanced diet is a good and relevant strategy to reduce liver metabolic disorders caused by the high consumption of fructose and saturated fat.
我们假设,食用奇亚籽(Salvia hispanica L.)粉(CF)和奇亚籽油(CO)可改善喂食高脂高果糖(HFHF)饮食的Wistar大鼠(Rattus norvegicus)肝脏中的代谢紊乱。将动物喂食HFHF饮食(n = 30)或AIN93 - M标准饮食(n = 10)八周。在此期间后,将喂食HFHF的动物分为三组(n = 10):HFHF饮食组、HFHF加14.7% CF组和HFHF加4% CO组。对肝脏进行组织学和生化分析、基因表达、与炎症相关的蛋白质水平以及氧化应激评估。HFHF饮食导致动物出现脂肪生成、肝脏脂肪变性、氧化应激和炎症。摄入CF和CO增加了肝脏总抗氧化能力和超氧化物歧化酶,降低了一氧化氮水平和肝脏脂肪变性。此外,CF和CO分别导致SIRT1和PPARα的上调,而CF下调了TNF-α。摄入CO降低了血糖、甘油三酯和动物体重。奇亚籽对减轻肝脏促炎状态没有作用,这可能表明促炎状态在后期才出现。在不均衡饮食中添加奇亚籽是一种减少因高果糖和饱和脂肪摄入导致肝脏代谢紊乱的良好且相关的策略。
