Squid is a lean, high-protein seafood that delivers a concentrated source of complete protein with a relatively low fat content. Its macronutrient profile is dominated by protein, making it well-suited for muscle maintenance and tissue repair. Squid provides meaningful amounts of vitamin B12, which is critical for neurological function, red blood cell formation, and DNA synthesis. It is also a reliable source of riboflavin (B2), which participates in cellular energy production through the electron transport chain. The mineral profile includes copper, selenium, zinc, and phosphorus, each supporting distinct physiological roles from antioxidant defense to skeletal integrity. Selenium in squid contributes to thyroid hormone metabolism and immune regulation. Zinc supports enzymatic activity, wound healing, and protein synthesis throughout the body. Squid contains taurine, a conditionally essential amino acid involved in bile salt conjugation, cardiovascular function, and neurological stability. Iodine is present in notable concentrations, supporting thyroid hormone synthesis and basal metabolic rate regulation. The phosphorus content supports ATP production and bone mineralization. Squid is low in saturated fat and contains a favorable ratio of polyunsaturated fatty acids, including omega-3s in modest amounts. Its overall nutrient density relative to caloric load makes it a functionally efficient protein source within an animal-based dietary framework.
