Fish vs Meat Nutrition Comparison

Fish vs Meat Nutrition Overview

Fish and meat are both nutrient-dense protein sources used in meal planning worldwide. Fish entries in USDA FoodData Central often list EPA and DHA omega-3 fatty acids, vitamin D, and selenium. Red meat entries typically list higher iron, zinc, and vitamin B12 per 100 g. The best choice depends on your meal-planning goals, budget, cooking preferences, and overall dietary pattern.

Protein Comparison

Beef sirloin lists about 26 g protein per 100 g raw; pork loin lists roughly 20 g; lamb leg about 20 g. Most fish list 18–25 g per 100 g raw, with tuna toward the upper range. Both fish and meat provide complete protein for meal logging. We do not display amino acid charts because those require laboratory analysis per sample and are not consistently available in public databases.

Calories & Fat

Lean white fish and pork loin are lower-calorie options in our database. Fatty fish like salmon and mackerel list more calories from fat, including omega-3s. Marbled beef cuts like ribeye and lamb chop list higher saturated fat than lean sirloin or cod. Cooking with oil or butter increases calories for both.

Omega-3 vs Iron & Zinc

Fish — especially salmon, mackerel, herring, and sardines — lists substantially more omega-3 in USDA entries. Meat lists minimal long-chain omega-3 but often leads on iron and zinc. Beef chuck lists about 2.6 mg iron per 100 g raw; Atlantic salmon lists roughly 0.8 mg. These differences matter for meal logging, not as medical recommendations.

Fish vs Beef

Beef provides more iron and zinc in typical USDA comparisons; fatty fish provides more omega-3 and often vitamin D. Lean beef sirloin and lean white fish can both fit calorie-controlled meal plans.

Fish vs Pork & Lamb

Pork loin is among the leaner meat cuts and can list fewer calories than fatty fish. Lamb lists higher saturated fat than most fish and pork. Compare your exact cut and species above — results change with preparation method and serving size.

Environmental Considerations

Environmental impact varies widely by species, farming method, and region. Our tool uses a simplified planning index (1–5) for meal-planning context only — not a life-cycle assessment. Small oily fish like sardines and mackerel often score lower on our fish index; beef typically scores higher than poultry or pork on our meat index.

Food Safety

Cook fish and meat to USDA-recommended internal temperatures for food safety. Fish with higher mercury levels (e.g., swordfish, king mackerel) may warrant portion limits for some populations — see FDA advice. Store raw and cooked proteins separately; refrigerate leftovers within two hours.
