Spinach

Spinach is often referred to as a superfood due to its high nutrition density. For instance, it is loaded with vitamin K, it has very generous amounts of beta-carotene (vitamin A precursor) and manganese, and it offers us a good amount of magnesium, folate, potassium, iron, riboflavin, and so many more! It’s also a great source of eye carotenoid superstars lutein and zeaxanthin.

But spinach has a dark side, an incredibly high amount of oxalates. Oxalates bind to calcium and can cause kidney stones. For this reason, anyone with underlying kidney conditions should minimize their spinach intake or avoid it altogether.

When eaten in moderation, spinach is considered safe for healthy individuals, including adults, pregnant women, children, and babies who are over 8 months old. It’s also safe in moderation for healthy cats and dogs.

Important Things to Know

Hover over each of the facts below to flip the tiles and learn more details!

The calcium in spinach is not for us

Don’t be deceived by the high amount of calcium in spinach. Since oxalate binds to calcium and spinach is very high in oxalates, the calcium in spinach is taken. There are many other greens that are high in calcium and low in oxalates, including kale and collard greens. Give them a try!

Beware of high oxalate content

A high intake of spinach can result in kidney stones, due to its high-oxalate content. If you suffer from kidney conditions, opt for other greens instead. If you don’t, it’s typically safe to include spinach-based meals in your menu up to 8 times a month. Limit your intake of juiced or blended spinach because oxalates are absorbed faster in liquid form. Learn more.

Spinach is a natural source of folate

One cup of cooked spinach offers a pregnant woman 43% of the total folate she needs. Natural sources of folate are recommended over folic acid (folate’s synthetic form) which can lead to cancer and other concerns. Green vegetables in general are great sources of folate, as well as beans. Learn more.

Don’t give spinach to babies under 6 months old!

Spinach is very high in nitrates, which turn hemoglobin in our red cells into methemoglobin.

  • Hemoglobin carries oxygen to our body tissues
  • Methemoglobin keeps it all to itself!

Fortunately, our red cells produce an enzyme that turns methemoglobins back into hemoglobins. But we don’t produce enough until we are between 3 and 6 months old. Learn more.

Spinach is #2 in the Dirty Dozen

The Dirty Dozen lists the top 12 foods with highest pesticide levels. Sadly, spinach is #2 and other top greens are #3. Whenever possible, buy organic. Always wash your produce under running water before preparing and eating.

Watch out for interactions with anticoagulants

Spinach is very high in vitamin K and therefor you need to watch out for vitamin K interactions. A sudden increase in vitamin K during chronic anticoagulant therapy (Warfarin/Coumadin) may lead to clot formation, and a sudden decrease may lead to bleeding. If you change the amount of green vegetables you typically include in your diet while taking these anticoagulants, be sure to talk to your doctor. Learn more about vitamin K.
