How to Eat Spinach
Spinach is extremely versatile - enjoy raw in salads and smoothies, or cooked in sautees, soups, pasta dishes, and omelets. Cooking reduces volume significantly (one pound cooks down to about a cup) and increases absorption of some nutrients like beta-carotene. Baby spinach has a milder flavor than mature leaves. Pair with foods high in vitamin C to enhance iron absorption.
Selection and Storage
Choose crisp, dark green leaves without yellowing or wilting. Store unwashed in the refrigerator crisper for up to a week. Wash thoroughly before use as spinach can harbor sand and dirt. Pre-washed spinach is convenient but has a shorter shelf life. Frozen spinach retains most nutrients and stores for months.
Dietary Considerations
Spinach is extremely low in calories and naturally vegan and gluten-free. It's ideal for weight loss diets due to high nutrient density per calorie. Those on blood thinners should maintain consistent vitamin K intake. High oxalate content may be a concern for those prone to kidney stones.
