Brazil nuts (BN) (Bertholletia excels, Bonpl.), are of great importance because of their nutritional properties and economic value. They can be consumed in natura or as flour (BNF). In this study, we evaluated the effects of BNF and BN intakes (Both 5% and 15%) on metabolic parameters of rats for 15 days. Serum Selenium (Se) levels were higher in BN-15% and BNF-15% groups. Lipid content was reduced in retroperitoneal and epididymal adipose tissues in all groups and in the BN-5% group in the liver. However, liver lipids increased in the BNF-15% group. The levels of carbonylated proteins and lipid peroxidation in the liver were not altered. The data reveal that the increase in hepatic lipids in the BNF-15% group probably occurred due to the high concentration of free fatty acids present in the flour. The Se bioavailability in the diet contributed to the preservation of the liver function in rats. PRACTICAL IMPLICATIONS: The consumption of BN is common in the population. However, changes in eating habits have led to a more frequent consumption of vegetable derivatives, such as drinks and oils. The cake residue generated after processing is still considered of high nutritional value, since it is a source of protein and minerals such as Se. Because of its low cost, the use of pie at the industrial level is becoming increasingly more interesting for the development of new products, and the Brazil nut flour (BNF) is considered a good option. Our study showed that just like BN, BNF can be a source of selenium for the body, although changes in lipid metabolism and physiological parameters can be observed depending on the amount used. We believe that the results of this investigation can be used to guide the development of new technologies and products containing BN.
巴西坚果（BN）（巴西栗，Bonpl.），因其营养特性和经济价值而具有重要意义。它们可以直接食用或制成面粉（BNF）。在本研究中，我们评估了15天内摄入5%和15%的BNF和BN对大鼠代谢参数的影响。BN-15%组和BNF-15%组的血清硒（Se）水平较高。所有组的腹膜后和附睾脂肪组织以及BN-5%组肝脏中的脂质含量均降低。然而，BNF-15%组肝脏中的脂质增加。肝脏中羰基化蛋白质水平和脂质过氧化未发生改变。数据显示，BNF-15%组肝脏脂质增加可能是由于面粉中存在的高浓度游离脂肪酸所致。饮食中的硒生物利用度有助于保护大鼠的肝功能。实际意义：巴西坚果在人群中食用很普遍。然而，饮食习惯的改变导致人们更频繁地食用植物衍生物，如饮料和油类。加工后产生的蛋糕残渣仍被认为具有很高的营养价值，因为它是蛋白质和硒等矿物质的来源。由于成本低廉，在工业层面使用饼粕开发新产品变得越来越有吸引力，巴西坚果面粉（BNF）被认为是一个不错的选择。我们的研究表明，与巴西坚果一样，BNF也可以是人体硒的来源，尽管根据使用量的不同，可以观察到脂质代谢和生理参数的变化。我们相信，这项研究的结果可用于指导含巴西坚果的新技术和产品的开发。
