Consumers are increasingly interested in food products with high nutritional value and health benefits. For instance, fish consumption is linked with diverse positive health benefits and the prevention of certain widespread disorders, such as obesity, metabolic syndrome, or cardiovascular diseases. These benefits have been attributed to its excellent nutritional value (large amounts of high-quality fatty acids, proteins, vitamins, and minerals) and bioactive compounds, while being relatively low-caloric. Atlantic bluefin tuna () is one of the most consumed species worldwide, motivated by its good nutritional and organoleptic characteristics. Recently, some organizations have proposed limitations on its consumption due to the presence of contaminants, mainly heavy metals such as mercury. However, several studies have reported that most specimens hold lower levels of contaminants than the established limits and that their richness in selenium effectively limits the contaminants' bioaccessibility in the human body. Considering this situation, this study aims to provide baseline data about the nutritional composition and the latest evidence regarding the beneficial effects of Atlantic bluefin tuna consumption. A review of the risk-benefit ratio was also conducted to evaluate the safety of its consumption, considering the current suggested limitations to this species' consumption.
消费者对具有高营养价值和健康益处的食品越来越感兴趣。例如，食用鱼类与多种积极的健康益处以及预防某些常见疾病（如肥胖、代谢综合征或心血管疾病）有关。这些益处归因于其优异的营养价值（大量优质脂肪酸、蛋白质、维生素和矿物质）以及生物活性化合物，同时热量相对较低。大西洋蓝鳍金枪鱼（）是全球消费最多的鱼类品种之一，因其良好的营养和感官特性而受到青睐。最近，一些组织由于其存在污染物（主要是汞等重金属）而提议限制其消费。然而，多项研究报告称，大多数样本的污染物含量低于既定限值，并且其丰富的硒含量有效地限制了污染物在人体中的生物可及性。考虑到这种情况，本研究旨在提供有关大西洋蓝鳍金枪鱼营养成分的基线数据以及食用大西洋蓝鳍金枪鱼有益效果的最新证据。还对风险效益比进行了评估，以考虑到目前对该物种消费的建议限制，评估其消费的安全性。
