Made from fresh, raw tuna, sashimi is not only a delicacy but also a nutrient-rich food that can be part of a healthy diet. The health benefits of tuna sashimi are attributed to its high protein content, low calorie count, and abundance of essential nutrients like omega-3 fatty acids, vitamins, and minerals.
