Seafood could be a promising way to supplement healthy fatty acids and trace elements to the Peruvian diet. Seafood from northern Peru was characterized with the highest relative concentrations of long-chain polyunsaturated fatty acids (LC-PUFAs), while in the center region marine species had the lowest As and Pb contents. Peruvian marine species are rich in LC-PUFAs and micro-nutrients (Cu, Fe, Mn, Zn), including species considered as potentially edible (e.g. Cycloxanthops sexdecimdentatus), but also non-edible species (e.g. Caulerpa filiformis). Nevertheless, it is crucial to consider toxic metals, e.g. As and Cd, which could pose a risk for consumers. High levels of beneficial LC-PUFAs and micro-nutrients would be taken up (up to 80% of the recommended values) when the Peruvian population would consume the estimated safe amount of seafood. Scoring species for fatty acid and metal content resulted in gastropods (e.g. Bursa ventricosa) as being the least beneficial species.
海鲜可能是为秘鲁饮食补充健康脂肪酸和微量元素的一种有前途的方式。来自秘鲁北部的海鲜具有最高的长链多不饱和脂肪酸（LC-PUFA）相对浓度，而在中部地区，海洋物种的砷和铅含量最低。秘鲁的海洋物种富含 LC-PUFA 和微量营养素（Cu、Fe、Mn、Zn），包括被认为具有潜在可食用性的物种（例如 Cycloxanthops sexdecimdentatus），也包括不可食用的物种（例如 Caulerpa filiformis）。然而，考虑到有毒金属（例如砷和镉）至关重要，因为它们可能对消费者构成风险。当秘鲁人口食用估计安全量的海鲜时，将摄入大量有益的 LC-PUFA 和微量营养素（高达建议值的 80%）。根据脂肪酸和金属含量对物种进行评分，结果表明腹足类动物（例如 Bursa ventricosa）是最不利的物种。
