A 100 g raw serving typically contains approximately 146 kcal, 23 g protein, and 5 g fat, making it a nutrient-dense option for a balanced diet .

Fiber Content

As a fish, yellowtail does not contain dietary fiber, which is naturally found in plant-based foods. Any reference to "fiber" in the context of yellowtail may be a misunderstanding, as fish provide protein and healthy fats rather than carbohydrates or fiber .
