Who Should Avoid Eating Spinach?

Unless you have aspinach allergy, the vegetable is generally safe. However, there are a few potential risks to consider.

Kidney Stones

Akidney stoneis a cluster of crystals that form in your kidneys. They are made of minerals and other substances present in urine. The most common type of kidney stone iscalcium oxalate stones,which form when there is too much oxalate in the urine.

People with a history of calcium oxalate stones are often advised toavoid oxalate-rich foods, including spinach, to reduce the risk of new stone formation. Boiling spinach can reduce its oxalate content.

Blood-Clotting

Consuming too much vitamin K through food or supplements can decrease the effectiveness of warfarin, increasing the risk of blood clots. Consuming less vitamin K may increase the risk of dangerous bleeding.

Medication Interactions

Due to its high vitamin K content, spinach may have a serious interaction with warfarin. If you take this medication, talk to your healthcare provider to determine how much vitamin K you should consume daily.

Certain medications may decrease vitamin K absorption in the body. These include:

Does Preparing Spinach a Certain Way Make It Healthier?

Whether raw or cooked, spinach is incredibly nutritious. Still, how you prepare spinach can impact its nutritional value, with each method having pros and cons.

Raw spinach offers the highest amount of vitamin C and phenolic compounds. And if you want the maximum amount of lutein, eat spinach in a smoothie. Chopping spinach increases the release of lutein from its leaves.

Steaming spinach can also preserve its folate content and results in significantly higher levels of beta-carotene than raw spinach.
