Comparisons with Other Leafy Greens

When you compare water spinach to other leafy greens, it stands out due to its unique nutritional profile. While spinach, kale, and other greens are often praised for their health benefits, water spinach offers several advantages:

• vs. Spinach: While both are rich in iron and vitamin A, water spinach is higher in vitamin C and contains more fiber.
