Why fish works for a light dinner

• High protein, low fuss: 20–30 g protein per serving helps you feel full with fewer calories.
• Omega-3s: Fatty fish (salmon, sardines, trout) deliver EPA/DHA for heart health.
• Fast cook times: Thin fillets sear, bake, or air-fry in 6–12 minutes, so you can add a simple veg + whole-grain side and be done.

How to buy & prep quickly

Smart shopping

• Weeknight MVPs: salmon, cod, tilapia, trout, shrimp, canned tuna/salmon.
• Look for freshness: firm flesh, mild smell; or choose frozen, which is often flash-frozen at peak quality.
• Mercury-savvy picks: salmon, cod, tilapia, pollock, shrimp are typically lower-mercury choices.

10-minute prep playbook

• Season: salt + pepper + acid (lemon/lime) + 1–2 herbs/spices.
• High heat, short time: pan-sear, broil, air-fry, or bake at 425°F until just opaque and flakes easily.
• Plate with fiber: steamed veg, bagged salad, microwaved quinoa/brown rice for a balanced, light plate.

Safety & mercury: simple guide

• Cook to safe temp: most fish are safely cooked at 145°F (63°C) and flake easily with a fork.
• Mercury basics: choose a variety of lower-mercury fish like salmon, cod, tilapia, pollock, shrimp; limit high-mercury species (e.g., king mackerel, shark, swordfish).
• Frequency: a general heart-health pattern includes about two servings of fish per week, especially fatty fish.

FAQs

Which fish are best for a light, low-calorie dinner?

Cod, tilapia, pollock, shrimp, and many white-fish fillets are lean and cook quickly. Salmon and trout are slightly higher in calories but bring heart-healthy omega-3s.

How do I keep fish from drying out?

Start with even-thickness fillets, cook hot and short, and remove when just opaque and flaky. A quick sauce (lemon-yogurt, salsa verde) adds moisture without many calories.

Is canned tuna or salmon a healthy shortcut?

Yes—both are high in protein and budget-friendly. Choose tuna packed in water; mix with beans or crunchy veg for a balanced, light meal.

How many fish dinners per week?

For most adults, about two fish meals per week (especially fatty fish) supports heart health alongside a balanced diet.
