Spinach Is Exceptionally Nutritious—So Why Does Comfort Keto Prepare It Differently?

Spinach has earned its reputation as one of the world's most nutritious vegetables. It is an excellent source of vitamins A, C, and K, folate, magnesium, iron, and numerous beneficial plant compounds that support overall health.

So why has Comfort Keto changed the way we prepare spinach?

The answer lies in one naturally occurring compound found in spinach in exceptionally high amounts: oxalates.

Spinach Is Exceptionally High in Oxalates

Oxalates (salts of oxalic acid) occur naturally in many plant foods and serve an important biological function within the plant. Although oxalates are present in a wide variety of vegetables, spinach contains considerably more than almost any other commonly consumed leafy green.

One cup of raw spinach contains approximately 650 mg of oxalates, while one cup of cooked spinach contains roughly 1,500 mg. Cooking does not create additional oxalates. Instead, spinach shrinks dramatically during cooking, concentrating many more leaves into a single cup.

Fortunately, not all dietary oxalate is absorbed. When calcium is consumed with meals, much of the oxalate binds to calcium in the digestive tract and is eliminated in the stool before it can be absorbed into the bloodstream.

How We Prepare Spinach at Comfort Keto

Briefly boiling spinach helps reduce its soluble oxalate content while preserving much of its color, flavor, texture, and nutritional value.

Despite its high oxalate content, we have not eliminated spinach from our menu. In fact, it remains an important ingredient in several of our recipes, including one of our most popular dishes—our Creamy Tuscan Chicken.

What has changed is how we prepare it.

As our understanding of nutrition has evolved, we've refined our cooking techniques to better reflect the available scientific evidence while preserving the traditional character of our dishes.

Whenever practical, we briefly boil spinach before incorporating it into a recipe. The goal is not to boil the life out of it, but simply to allow a portion of the soluble oxalates to leach into the cooking water. The spinach is then drained thoroughly, lightly rinsed, and incorporated into the finished dish.

This simple preparation method helps reduce the amount of naturally occurring soluble oxalates while preserving the spinach's vibrant color, pleasant texture, fresh flavor, and much of its nutritional value.

We Rarely Serve Raw Spinach

As a general rule, we do not serve raw spinach as the primary leafy green in our meals.

The only exception is when a small amount of baby spinach is included as part of a pre-packaged spring salad mix. In those blends, spinach represents only a small portion of the overall mix rather than the dominant ingredient.

For most salads, we prefer naturally low-oxalate leafy greens such as romaine lettuce, butter lettuce, cabbage, bok choy, kale, and other spring greens.

A Better Everyday Choice

Although spinach is exceptionally nutritious, several other leafy greens offer comparable nutritional benefits while containing only a fraction of the oxalates.

These are some of our favorite naturally low-oxalate vegetables that we regularly incorporate into Comfort Keto meals.

Kale is one of our favorites. Like broccoli, it provides highly absorbable calcium and is naturally very low in oxalates, making it an excellent choice for everyday meals.

That doesn't mean spinach should be avoided. Rather, it illustrates how thoughtful ingredient selection and preparation can help reduce unnecessary dietary exposure while preserving the enjoyment and nutritional value of whole foods.

Our Philosophy

Our approach to spinach reflects a broader philosophy that guides every recipe we create at Comfort Keto.

Our recipes are our own original creations, inspired by time-tested culinary traditions from around the world. They are also living recipes—continually evolving through careful testing, evaluation, and refinement.

As promising ingredient alternatives and preparation techniques are identified, we continually test and evaluate them against our current recipes. Every potential improvement is assessed for flavor, texture, authenticity, and nutritional quality. Only when a change genuinely enhances the dining experience does it become part of the next evolution of the dish.

The same philosophy applies to spinach. We don't avoid it—we prepare it more thoughtfully.

One of the greatest rewards comes from our long-term customers, who often tell us that we've "outdone ourselves" once again. To us, there is no greater compliment. It reminds us that continual refinement is worthwhile and reinforces our commitment to never stop improving.

At Comfort Keto, great recipes are never truly finished. They continue to evolve—one thoughtful refinement at a time.

Bon Appétit!
