Raw spinach contains an inhibitor called oxalic acid or oxalate. Oxalic acid naturally binds with minerals like calcium and iron, making them harder for the body to absorb. Cooking spinach can help unlock these iron absorption inhibitors and hence increase iron bioavailability.
What is the best way to absorb iron from spinach?
Serving Spinach for Increased Iron Intake
If you love spinach and include it in several dishes throughout the week, pair it with vitamin C-rich foods, like orange juice, strawberries or red bell peppers. Vitamin C enhances nonheme iron absorption, helping your body absorb a little more.

Is it better to eat spinach raw or cooked?
Spinach. The leafy green is packed with nutrients, but you’ll absorb more calcium and iron if you eat it cooked. The reason: Spinach is loaded with oxalic acid, which blocks the absorption of iron and calcium but breaks down under high temperatures.
What helps the absorption of calcium?
vitamin D
To absorb calcium, your body also needs vitamin D. A few foods naturally contain small amounts of vitamin D, such as canned salmon with bones and egg yolks. You can also get vitamin D from fortified foods and sun exposure. The RDA for vitamin D is 600 international units (15 micrograms) a day for most adults.
How do you avoid oxalates in spinach?
Cooking Spinach Decreases Oxalates
Researchers found that steaming and boiling were effective cooking methods for decreasing the oxalate content of spinach and other vegetables. Boiling appears to be more effective; it reduced the soluble oxalate content by 30 percent to 87 percent.
What enhances calcium absorption?
Vitamin D
Vitamin D also is required for calcium absorption. The best source of vitamin D is sunshine for approximately 20 minutes per day, which is not a problem for most people who live in the South. Vitamin D also is found in many other sources and generally is not responsible for poor calcium absorption.
Does cooked spinach block calcium absorption?
Spinach and Other Foods with Oxalates
