How Spinach Fits Into a Diet
Spinach is useful when you want a very low-calorie leafy green with vitamin K, folate, carotenoids, potassium, and meal volume.
Pair spinach with eggs, beans, potatoes, lentils, fish, chicken, tofu, olive oil, citrus, or whole grains to improve satiety and meal balance.
Raw leaves, boiled spinach, sauteed spinach, frozen spinach, creamed spinach, and restaurant sides differ because water loss, oil, cream, and salt change the final serving.

Methodology & Nutrition Data Sources
How we calculate nutrition data for Spinach: Calorie and macronutrient values are standardized reference profiles, generally based on USDA FoodData Central entries where available, then scaled to the serving you choose. Entries may come from different FDC data types or releases, and brand or preparation differences can change the numbers.
- Calorie and macronutrient data sourced from the USDA FoodData Central , the federal food composition database used as the main reference where a matching entry exists.
- Daily Value context: for % DV comparisons, use the FDA Daily Value reference amounts for a 2,000 calorie diet (21 CFR 101.9).
- Dietary reference intakes (DRI) for vitamins and minerals are available in the National Academies Dietary Reference Intake tables for further reading; this page does not calculate DRI percentages.
- Glycemic index values are approximate listed values; GI varies by variety, ripeness, and preparation, so compare with the Harvard Health Glycemic Index Reference and the University of Sydney GI database.
- Dietary guidelines context from the HHS/USDA Dietary Guidelines for Americans 2020–2025 , the federal evidence-based nutrition guidance.
