What changes the calories
- The figures are for drained solids, so weighing the tuna with its liquid gives a heavier weight than the fish you actually eat.
- Tuna canned in oil is higher in calories than tuna in water because the fish holds some of the oil, even after draining.
- Mixing tuna with mayonnaise, dressing or oil adds the calories of those ingredients, which can easily exceed the tuna itself.
- Can sizes and how well you drain vary, so the amount of fish in one can is not always the same.
Tips for logging it accurately
- Drain the tuna well and weigh the fish itself rather than relying on the can's net weight, which includes the liquid.
- Log any mayo, oil, cheese or bread separately so the extras in a tuna salad or sandwich are counted.
- In BerryFit, choose the canned-in-water, drained entry and adjust the grams to match what you weighed.
