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.
The good news is that oxalic acid is broken down upon heating, so there is no loss of nutrients in steamed or sautéed spinach.
Spinach is a green leafy vegetable that we all know to be really healthy, due to the presence of high levels of antioxidants in it. However, the best way to eat spinach is not after blanching or boiling it, but rather adding it to your smoothies or juicing it, says a new study.
Heating vegetables releases antioxidants by breaking down cell walls. Studies have found that eating cooked spinach and carrots – versus raw – results in much higher blood levels of beta-carotene, an antioxidant thought to guard against heart disease and lung cancer.”
If you eat spinach every day in excessive amounts (more than a bowl) there can be adverse health effects. Most commonly these include gas, bloating and cramps due to its high fiber content. Eating too much spinach can also interfere with the body's ability to absorb nutrients.
Spinach is a great source of nutrients that reduce inflammation and make it faster for your body to recover. In addition to Vitamin E, the greens are a great source of anti-inflammatory compounds, B vitamins, and omega-3 fatty acids.

It can be said that between the two vegetables, spinach is said to be healthier than broccoli as it has high water content, a lesser amount of sugars and is richer in protein, magnesium, Vitamin E, manganese and potassium as compared to broccoli.
Thankfully, there are ways to eat the veggie without giving up taste or nutrition. Instead of boiling spinach, Jessica Cording, R.D., suggests steaming or microwaving it so you get more nutritional value in every bite. She likes to keep baby spinach on-hand to add into smoothies, soups, or omelets.
According to the USDA Nutrient Database, per gram, both raw spinach and frozen spinach (unprepared or prepared by boiling and draining), contain around the same amount of magnesium (about 75-82 milligrams per 100 grams of spinach).
Contrary to what some books say, cooking does not destroy oxalic acid. However, blanching your greens for a few minutes and disposing of the water leaches out roughly one third of the oxalic acid.
According to Texas A&M Extension's website, spinach has twice as much potassium, protein, calcium, iron, niacin and vitamins A, C, B, C and B-12 as any other leaf vegetable. Spinach also contains more fiber and minerals including magnesium, phosphorus and potassium than any of the four lettuce types.
Generally, the best way to cook spinach is on the stovetop. Sautéing spinach is an especially quick and easy way to cook spinach, which also evaporates excess moisture in the leaves. However, you can also boil or steam spinach in just a few minutes.
Boiling vegetables causes a significant amount of nutrients that dissolve in water - vitamin C, folate and thiamin (vitamin B1) - to be leached away. Steaming is much gentler on nutrients because vegetables don't come in contact with cooking water.
Instead of sauteing spinach leaves in oil or cooking them in water, you can add them to soup or stew near the end of the cooking time. The broth that boils them will capture any nutrients that leech out of the leaves.
1. Spinach. This leafy green tops the chart as one of the most nutrient-dense vegetables. That's because 1 cup (30 grams) of raw spinach provides 16% of the Daily Value (DV) for vitamin A plus 120% of the DV for vitamin K — all for just 7 calories ( 1 ).
Nightshade vegetables, like peppers, potatoes, and eggplant, are are controversial, because many claim they can cause inflammation, according to Cynthia Sass, a registered dietician. This can lead to some pretty serious complications down the line: heart disease, cancer, and diabetes, to name a few.
The Bottom Line
Kale and spinach are highly nutritious and and associated with several benefits. While kale offers more than twice the amount of vitamin C as spinach, spinach provides more folate and vitamins A and K. Both are linked to improved heart health, increased weight loss, and protection against disease.
To aid in iron absorption add vitamin C, such as a squeeze of lemon juice over your sauteed spinach or eat your spinach with other vitamin C rich foods like bell peppers or citrus fruits.
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.
Although it's difficult to find authoritative limits for spinach consumption on a daily or weekly basis, MedicineNet confirms that a bowl a day, a moderate amount, is safe for most people.
green leafy vegetables, such as spinach, kale, and collards. nuts like almonds and walnuts. fatty fish like salmon, mackerel, tuna, and sardines. fruits such as strawberries, blueberries, cherries, and oranges.
Because vitamin K is a fat-soluble vitamin, cooking vegetables won't decrease the level of vitamin K, but it may deplete other vitamins found in green leafy vegetables. It's wise to choose cooking methods that preserve vitamins to get the most nutritional value from your vegetables.
But spinach is LIKELY UNSAFE for infants that are less than 4 months old. The nitrates in spinach can sometimes cause a blood disorder (methemoglobinemia) in young infants. Allergies: People who are sensitive to latex or certain molds are more likely to have allergic responses to spinach.
Does blending destroy nutrients? Also no. Blended fruits and veggies are nutritionally comparable to their whole counterparts. So, if making a smoothie helps you get more produce into your day, then by all means continue doing so!
