The short answer
Provides folate, carotenoids, vitamin K, and magnesium with little energy.
- Evidence and scope
- Food context; study findings do not grade the whole food.
- Important limitation
- Evidence is strongest for eating a variety of vegetables; spinach-specific disease or lifespan claims remain uncertain.
- Before deciding
- No single food has been shown to extend human lifespan; the overall dietary pattern and what this food replaces matter.
01 / NUTRIENTS & FORM
Nutrient snapshot
The exact food form matters. Raw, cooked, drained, dried, fortified, and branded versions can have meaningfully different values.
Provides folate, carotenoids, vitamin K, and magnesium with little energy.
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

02 / RESEARCH
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.
Daily Intake of Lemna minor or Spinach as Vegetable Does Not Show Significant Difference on Health Parameters and Taste Preference.
This source clarifies absorption, biomarkers, tolerability, or another research context; it does not demonstrate a clinical health benefit by itself.
- Study design
- Randomized controlled trial
- Tested form / scope
- Whole food
- Editorial interpretation
- Evidence is strongest for eating a variety of vegetables; spinach-specific disease or lifespan claims remain uncertain.
- 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.
