Sardines are one of the most nutrient-dense fish you can eat — packed with protein, omega-3 fatty acids, calcium, and vitamin D in a small, affordable package. This Sardine Nutrition Calculator turns a single serving size into a full nutrition breakdown, so you can log your meal, plan high-protein recipes, or compare canned vs. fresh options in seconds.
Choose the form of sardines you are eating (raw Atlantic, canned in oil, or canned in water), enter your portion in grams or ounces, and the tool will estimate calories, protein, total fat, saturated fat, omega-3 EPA + DHA, calcium, vitamin D, sodium, and carbs. The results also show how each nutrient contributes to a standard 2,000-calorie daily diet.
Because sardines vary by brand and packing liquid, treat the numbers as a practical estimate — best for meal planning and general nutrition tracking.

📊 Nutrition breakdown
How It Works
The calculator uses USDA-style reference values for sardines per 100 grams of edible portion, then scales them to your serving size. This is the same approach used by professional nutrition databases: take a known nutrient density and multiply it by the weight of the food you actually eat.
Because sardines are eaten whole — including bones, skin, and small amounts of packing liquid — the nutrient values are notably higher in calcium, vitamin D, and omega-3s than typical white fish fillets. The canned-in-oil values assume the fish are drained before weighing; if you also consume the packing oil, add roughly 9 g of fat and 80 kcal per tablespoon of oil retained.
Formula used: nutrient value = (serving weight in grams ÷ 100) × nutrient per 100 g. Daily value percentages are based on a 2,000-calorie diet, with reference intakes for protein, fat, calcium, vitamin D, and sodium as published by the FDA.
How to Use This Tool
- Enter your serving size in grams or ounces, or click a preset such as "1 can (85 g)" or "3 oz".
- Select the form of sardines: fresh Atlantic raw, canned in oil (drained), or canned in water (drained).
- Click "Calculate nutrition" to see calories, protein, fat, omega-3s, calcium, vitamin D, sodium, and carbs.
- Read the % Daily Value for each nutrient to judge how the serving fits into your daily targets.
Reference Table: Sardine Nutrition per 100 g
| Form | Calories | Protein | Total fat | Omega-3 | Calcium | Sodium |
|---|---|---|---|---|---|---|
| Fresh Atlantic (raw) | 208 kcal | 24.6 g | 11.5 g | 1.6 g | 382 mg | 70 mg |
| Canned in oil (drained) | 208 kcal | 24.6 g | 11.5 g | 1.6 g | 382 mg | 250 mg |
| Canned in water (drained) | 177 kcal | 20.9 g | 10.5 g | 1.4 g | 382 mg | 200 mg |
Values are composite estimates for edible sardine meat. Brands vary; check the label for exact numbers, especially sodium and fat.
Example Calculations
Example 1 — One can in oil: An 85 g can of sardines packed in oil, drained, gives a scale factor of 85 ÷ 100 = 0.85. Protein ≈ 24.6 × 0.85 = 20.9 g, calcium ≈ 382 × 0.85 = 325 mg, vitamin D ≈ 193 × 0.85 = 164 IU, and calories ≈ 208 × 0.85 = 177 kcal.
Example 2 — 4 oz in water: 4 oz converts to 113.4 g, giving a scale factor of 1.134. Using canned-in-water values: protein ≈ 20.9 × 1.134 = 23.7 g, calories ≈ 177 × 1.134 = 201 kcal, and omega-3 ≈ 1.4 × 1.134 = 1.6 g.
Tips & Best Practices
- If you eat the packing oil, add about 80 kcal and 9 g fat per tablespoon to the canned-in-oil estimate.
- Pasteurized and smoked sardines may have 40–80 mg more sodium per serving; use label values when available.
- The bones are edible and are the main source of calcium — do not remove them if you want the full calcium benefit.
- For meal planning, pair sardines with a carbohydrate source to balance the meal, since sardines contain almost no carbs.
Frequently Asked Questions
Are sardines a good source of calcium?
Yes. A 100 g serving of sardines with bones provides about 382 mg of calcium — roughly 30% of the Daily Value. That is comparable to a cup of milk and makes sardines one of the best non-dairy sources of calcium.
Why is the omega-3 amount so high?
Sardines are small, oily fish that store omega-3 fatty acids in their flesh. A typical serving provides about 1.4–1.6 g of EPA plus DHA, which already meets the 250–500 mg daily recommendation used by many health organizations.
Should I choose canned in oil or water?
Both are nutritious. Canned in water is lower in calories and fat, while canned in oil has a richer flavor and may have marginally higher vitamin D because the oil helps retain fat-soluble vitamins. Drain the oil to keep the numbers closer to the values shown here.
