Identify the tuna wording before treating every can as the same fish. US FDA/EPA advice puts canned light and albacore/white tuna in different categories.
Check the intended audience
The advice addresses people who might become pregnant, are pregnant or breastfeeding, and children aged 1–11. It is not every adult's personal allowance or a mercury test of a particular can.
Match the package name to the chart
Canned light, including skipjack, is a Best Choice; albacore/white is a Good Choice. Bigeye tuna is in the Avoid category. Do not interpret light as a low-calorie claim here.
Do not guess an unidentified species
A pale photograph or water-versus-oil packing does not establish species. Ask the maker when the ingredient name is unclear and locate the exact chart entry.
Read portions and frequency for the audience
A category alone does not set cans per day. Read the official age-specific portion and weekly guidance, and follow professional advice for individual medical conditions. Identify species accurately when varying fish choices too.
Turn observations into a decision
| Observation or wording | Meaning and limit | Next action |
|---|---|---|
| Tuna packed in water; species not stated | Packing liquid cannot establish Best Choice status | Check ingredients and ask the maker for the species |
| Canned light or skipjack | Best Choices entry in the US chart | Check whether the audience applies, then read its portion and weekly guidance |
| Albacore/white | Good Choices entry in the US chart | Read the Good guidance rather than borrowing the Best frequency |
| Bigeye | Choices to Avoid for the chart's audience | If the audience applies, consult suitable alternatives |
A worked example
Fictional shopping case: A says only 'tuna, water'; B says 'albacore/white'. A's species field is blank, so it cannot be ranked as the better choice. B can be matched to Good Choices before reading the audience and portion guidance. A count of two cans is not automatically two official portions.
