Tag: Protein in tuna

While often regarded as a lean protein, the fat content in raw tuna varies significantly by species and cut. Bluefin tuna, particularly prized for sashimi, can be notably fatty, while a serving of ahi (yellowfin) contains less than a gram of total fat. This variation is key to understanding the nutritional profile of the raw tuna you consume.

A 5-ounce raw yellowfin tuna steak contains approximately 155 calories, showcasing its low-calorie, high-protein profile. But the exact number for how many calories are in a 5 ounce tuna steak varies based on the species and preparation.
