Which fish is healthiest? Nutritionist reveals diet-friendly species
Praised for being a filling, yet low-fat source of protein, the likes of salmon, cod and sea bass are often recommended by nutritionists across the globe.
TL;DR
- Mackerel is rich in omega-3 fatty acids, but a third of its fat is saturated.
- Cod is an excellent lean protein source, high in iodine, but low in omega-3.
- Seabass offers high protein and omega-3s but can contain higher mercury levels.
- Salmon is a nutrient-dense all-rounder, high in omega-3, protein, vitamin D, and B12.
- Tuna is a lean protein source but concerns exist regarding mercury contamination, especially in larger species.
- Prawns are low in calories and fat but high in salt and often prepared in unhealthy ways.
- The NHS advises eating at least two portions of fish per week for omega-3 benefits.
