Kale, raw vs Spinach, raw
Fiber comparison — per 100g and per serving
Both Kale, raw and Spinach, raw are tracked in the USDA FoodData Central database. This comparison shows total fiber, soluble and insoluble fiber breakdown, fiber per serving, and fiber efficiency (grams per 100 calories) — giving a complete picture for anyone choosing between these two foods. Serving size matters as much as fiber density: a food with lower fiber per 100g may still deliver more fiber per serving depending on typical portion sizes.
