Living in the 21stcentury certainly has its perks. 

We have fridges, freezers, blenders and a whole host of other gadgets to make our life so much easier. 

This enables us to prepare meals ahead of time or even to have meals prepared from scratch in no time at all. 

Freezing spinach and other greens is one way to capitalise on these modern day benefits. 

Let’s look at why you’d want to and how you can!

Why would you want to freeze spinach?

Let’s start with how the nutrition profile of 1 cup of cooked spinach will look for you and then we can move into some of the benefits of spinach.

  • Some protein and carbs
  • Fibre
  • Vitamins
    • A and K – all that you need in a day and then some
    • Folate – over half of your daily needs
    • A good chunk of Vitamin B1, B2, B6, C and E
    • Beta-Carotene (Pre-Vitamin A)
    • A little bit of B3
  • Minerals
    • Almost all your daily Manganese
    • Popeye approved amounts of Iron
    • Sizable portions of magnesium, calcium, potassium, copper and phosphorous
    • A bit of zinc, sodium and selenium
  • Other compounds
    • Lutein and Zeaxanthin
    • Phytoecdysteroids

Based on these nutrients above, here are some of the benefits you might expect from regular spinach consumption.



Healthy Vision

Spinach contains amounts of beta-carotene, lutein and zeaxanthine in its nutritional makeup.

These are all compounds that have been shown to preserve the health of the eyes and reduce the occurrence of macular degeneration.

Bone Health

Beyond just calcium, there are many other nutrients that are needed to ensure optimal bone health.

Vitamin K is one of those and spinach contains a boatload of it.

Seriously, it could fill a boat. 

Adequate vitamin K has been shown to reduce the occurrence of osteoporosis and decreases fracture risk and more.

Stabilising blood sugar

With more and more of the population predicted to be on their way to diabetes year after year, methods of stabilising blood sugar are now more important than ever.

Spinach, like most greens, contains some fibre which can help to slow blood sugar spikes.

Cramping, headaches, blood pressure and more

Spinach is a great source of magnesium, a mineral that's involved in over 300 enzymatic reactions in our body.  

This is why spinach and any other magnesium-rich food can have such far reaching effects.

How to prepare your spinach for freezing

Is it as simple as freezing raw spinach?

It can be, but you’d be missing out on a lot of spinach’s benefits.

Spinach, like other greens, contains sizable amounts of oxalic acid. 

Oxalic acid is known to reduce the absorption of nutrients such as zinc, calcium and iron, so it is best to reduce levels of this compound as much as possible.

Even if you’re not concerned about levels of these minerals, oxalic acid in the diet should be reduced in people with a history of kidney issues, specifically kidney stones.

Fortunately, the fix is simple, cooking, blanching or boiling spinach and discarding the water removes much of the oxalic acid in spinach. 

Now freeze the spinach ready for use

Once you’ve completed the process above, feel free to blend the spinach up with a bit of water and then set in the freezer in your ice cube trays. 

Otherwise, as another alternative, cut the spinach into small chunks and freeze, then pop them out and into the blender when you’re ready to use them.

Too much work? All sounds too hard?
