Health Benefits

Spinach also has antioxidant content and it is believed to reduce blood pressure, improve vision, and bone health. Both vegetables are low in calories and contain fiber, vitamins, and minerals that can help support many aspects of health.

Cooking Applications

This makes it an ideal choice for dishes that require cooking for longer periods of time. Kale is also more enjoyable eaten raw, however, it takes longer to break down compared to spinach.

Price Comparison

Kale is often more expensive than spinach when purchased in the grocery store or farmer’s market. This is due to the fact that kale is more labor intensive to harvest and requires additional washing and preparation before it can be sold. Kale is usually sold in bags, while spinach is typically sold in bunches. The price difference between the two greens can also vary depending on the season and availability.


When considering replacing kale with spinach, it is important to take into account the nutritional content, health benefits, cooking application, flavor profile, and price.

Storage Methods

Kale and spinach can be stored in the refrigerator for up to five days if sealed in a plastic bag. Kale should be rinsed before storing, while spinach should not be washed until it is ready to be used. For longer-term storage, kale and spinach can be frozen and can last up to six months. Kale and spinach should not be stored at room temperature as this will cause the vegetables to spoil quickly.

Buying & Preparing Tips

When buying kale or spinach, it is important to look for fresh, crisp leaves with no signs of browning or wilting. Both vegetables should be washed thoroughly to ensure they are clean and safe to eat. Kale should be washed on both sides and dried before storage or cooking. Spinach should only be washed just before use and should be dried with a paper towel before cooking or adding to a raw dish.

Nutrient Absorption

Kale and spinach can be an excellent source of nutrients, but the vitamins and minerals can be lost during the cooking process. Kale that is steamed or boiled will retain more of its vitamins and minerals than spinach, due to its tougher texture. To get the most out of kale and spinach, they should be eaten raw or lightly steamed to keep the nutrients intact.
