Swordfish, flesh only, grilled

Swordfish is a fish eaten as steaks; the figures here describe grilled flesh only and are calculated from raw steaks. It mainly provides protein and fat, with 23g of protein and 5.2g of fat per 100g. This includes 1.2g of saturated fat, while the salt content is 0.43g.

Protein supports the maintenance and repair of body tissues. Swordfish also provides vitamin B12, which contributes to normal nerve function and red blood cell formation. Its salt and saturated fat content may be relevant to people monitoring these nutrients. UK food safety guidance advises avoiding swordfish during pregnancy because of its mercury content.
