Evaluation of the Nutritional Quality of the Five Commercial Fish Species From the Persian Gulf From Human Health Perspective

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
Based on the findings of this study, the best protein quality related to N. japonicus with an EAA index of 75.92. P. indicus has the best lipid quality due to the high ratio of ω‐3/ω‐6 (1.68) and PI (7.02). The abundant trace elements in all five fish species, K, Ca, Fe, and Zn, as well as these fish species, have good nutritional quality based on Na/K
