Tuna Akami is a primary source of high-biological value protein and essential micronutrients like Selenium, which acts as a cofactor for glutathione peroxidase to mitigate systemic oxidative stress. Its significant Vitamin B12 concentration ($7.5\mu g$) is critical for maintaining hematological integrity and preventing hyperhomocysteinemia, a risk factor for vascular dysfunction. While low in fat, it provides essential long-chain omega-3 fatty acids (EPA/DHA) that support neuroplasticity and cardiovascular health.
