Fish is one of the easiest wins for lower-carb, diabetes-aware cooking — naturally low in carbohydrate, high in protein and quick in the air fryer. These six dishes each list the carbs per portion.
Key takeaways
Q: Is fish good for a diabetic-friendly diet?
A: Yes — plain fish is virtually carb-free and high in protein, and oily fish adds healthy fats. The carbs come only from coatings and sides.
Q: How do you keep air fryer fish low-carb?
A: Skip breadcrumb coatings, season with herbs and lemon, and serve with non-starchy vegetables.
