The short answer
A rich source of EPA, DHA, protein, vitamin B12, and selenium.
- Evidence and scope
- Food context; study findings do not grade the whole food.
- Important limitation
- Evidence supports seafood patterns more clearly than mackerel-specific longevity claims; species affect mercury content.
- Before deciding
- Species, preparation, sustainability, and contaminant exposure matter. Pregnancy guidance and local advisories may change the best choice.
01 / NUTRIENTS & FORM
Nutrient snapshot
The exact food form matters. Raw, cooked, drained, dried, fortified, and branded versions can have meaningfully different values.
A rich source of EPA, DHA, protein, vitamin B12, and selenium.
We have not assigned a specific composition record to this food yet. Values will appear only after the food description, preparation state, edible portion, and serving weight are verified.
How nutrient values will be verified
- Planned display basis
- Practical serving and per 100 g
- Planned nutrient fields
- Energy, protein, carbohydrate, fiber, fat, sodium, and the most relevant micronutrients
- Publication rule
- Show the database, record ID, food form, serving weight, and verification date

Evidence map: baseline and emerging signals
The current baseline stays visually separate from credible findings that are mechanistic, responder-dependent, small, or not yet replicated.
The general interpretation that does not depend on one unreplicated positive result. An established limitation is as important as an established benefit.
Blood pressure-lowering effect of mackerel diet.
The abstract reports a qualified or outcome-specific signal. It does not establish a general health benefit beyond the tested form, population, comparator, and duration.
- Study design
- Clinical trial
- Tested form / scope
- Whole food
- Editorial interpretation
- Evidence supports seafood patterns more clearly than mackerel-specific longevity claims; species affect mercury content.
- Screening record
- One relevant human PubMed source was verified and classified. This is a source card, not a complete evidence synthesis or a count of favorable studies.
