Both foods are surely rich in nutrients, but they differ in their nutritional value. Moreover, one cannot consider them equal in terms of health benefits. Basically, kale tastes more bitter but gives you the same nutrients like vitamin K and calcium, while spinach goes down easier and has the same iron and folate benefits.
However, one of these greens is much better than the other for reducing inflammation itself, and it is probably not the one you have been purchasing further.
Nutritional Comparison: Kale vs Spinach Nutrition at a Glance
A. Caloric Content and Macronutrient Profiles
Kale and spinach itself are highly nutritious foods that do not add many calories to your diet, and they further provide essential nutrients without increasing weight. Moreover, basically, how do they compare the same way?

Absorption and Bioavailability
Understanding Oxalates and Their Impact
We are seeing that our body is only taking in some good things from green vegetables like kale and spinach, not everything. We are seeing that oxalates only might be causing the problem.
Basically, both kale and spinach have oxalic acid, but spinach has the same problem much more – it contains way higher levels.

Moreover, such individuals should take extra precautions when consuming foods high in these compounds. For these people, Kale is surely a better option. Moreover, it provides more benefits than other choices.
Cooking Methods That Maximize Nutrient Absorption
Also, raw leafy greens are not always the best choice, and cooking them further can make the nutrients more available to the body itself. As per the situation, this is quite surprising regarding the circumstances.
Actually, when you blanch spinach for just 30 seconds, it definitely reduces oxalates by 30-40% and helps your body absorb minerals much better. Steaming kale actually keeps all the good nutrients safe and definitely makes them easier for your body to use.

| Steaming | Reduces oxalates by 30%, preserves vitamins | The best method increases carotenoid availability by 40% |
| Boiling | Highest oxalate reduction (up to 90%) but loses water-soluble vitamins | Excessive nutrient loss |
| Sautéing | Moderate oxalate reduction, and fat helps absorb fat-soluble vitamins | Excellent for nutrient absorption when using healthy oils |
Food Combinations That Enhance Nutrient Uptake
The real benefit comes when you combine greens with other foods, which further enhances the nutritional value itself.
We are seeing that adding lemon juice or vinegar to kale and spinach salad helps our body take in iron three times better, not only for taste but because vitamin C makes iron absorption much easier. Basically, this is the same important point for spinach, which normally doesn’t absorb iron well.
As per health guidelines, fat is also beneficial regarding this matter. As per research, adding olive oil to your greens helps your body take in important vitamins A, E, and K that would otherwise just pass through without getting absorbed. Moreover, we are seeing that studies show absorption can go up by 400% when we add only one tablespoon of oil.
Basically, you should avoid calcium-rich foods when eating spinach because spinach has the same high oxalate content that can cause problems. You should eat your spinach salad and yogurt with at least one hour gap between them, as this will further help your body absorb nutrients properly itself. With low-oxalate kale, this timing is surely not as important. Moreover, the exact schedule becomes less critical to follow.
Fermented foods like kimchi or sauerkraut surely help your body absorb nutrients from greens better. Moreover, the good bacteria and enzymes in these foods break down harmful compounds that block nutrient absorption.
Practical Considerations for Daily Consumption
