Health Benefits of Spinach

Spinach Health Benefits: Nutrients, Antioxidants, and More

Spinach (Spinacia oleracea), native to central Asia, is one of the most versatile leafy green vegetables. Rich in vitamins and antioxidants, spinach protects you from chronic diseases and promotes brain, heart, and eye health.

You can enjoy spinach in various forms: cooked, fresh, frozen, or raw. Add it to smoothies, salads, side dishes, stir-fries, or even baked treats like brownies. Here are six health benefits of incorporating spinach into your diet:

Helps Manage Blood Pressure

Spinach contains nitrates, naturally occurring chemicals that open up blood vessels, improving blood flow and easing stress on your heart. A 2016 study involving seven women and eleven men found that consuming nitrate-rich drinks, including a spinach beverage, significantly increased blood nitrate levels. The spinach drink also lowered diastolic blood pressure (the bottom number in a blood pressure reading) and kept it low for five hours after consumption.

Helps Protect Against Diseases

Compounds in spinach can reduce oxidative stress, an imbalance between antioxidants and free radicals that damage cells. This stress increases the risk of chronic diseases like cancer, heart disease, and type 2 diabetes. By positively influencing gene expression related to inflammation and metabolism, eating spinach may protect against these conditions.

Is a Source of Antioxidants

Spinach is rich in antioxidants such as kaempferol, quercetin, myricetin, and isorhamnetin, all flavonoids that help reduce inflammation and protect against diseases like cancer, heart disease, and inflammatory conditions.

Is Full of Nutrients

Despite being low in calories, spinach is nutrient-dense. A three-cup serving provides over 300% of the daily value (DV) for vitamin K, over 160% for vitamin A, and 40% for vitamin C. Vitamin K and A support bone health, while vitamin C aids in wound healing. Spinach also provides 45% of the DV for folate, along with iron, magnesium, potassium, calcium, and small amounts of other B vitamins

Spinach Health Benefits: Nutrients, Antioxidants, and More

May Support Eye Health

Lutein, an antioxidant found in spinach, may reduce the risk of age-related macular degeneration (AMD), a leading cause of vision loss in people over 55. Lutein-rich spinach increases macular pigment optical density (MPOD), which acts like internal sunglasses to protect your eyes.

Might Lower the Risk of Cognitive Decline

The anti-inflammatory properties of spinach may protect against age-related cognitive decline. A 2015 study tracking over 900 adults aged 58–98 for about five years found that those who ate one to two servings of leafy green vegetables daily had cognitive abilities comparable to people 7.5 years younger.

Nutrition of Spinach

Spinach is low in calories, with about 91% of its mass being water. A one-cup portion of raw spinach contains:

  • Calories: 6.9
  • Fat: 0.117 grams
  • Sodium: 23.7 milligrams
  • Carbohydrates: 1.09 grams
  • Fiber: 0.66 grams
  • Added sugars: 0 grams
  • Protein: 0.858 grams

Risks of Spinach

To maximize spinach’s health benefits, vary your consumption methods—some raw, some cooked—but avoid overcooking to preserve nutrients. For example, raw spinach retains more lutein, while microwaving preserves vitamin K. Blanching reduces vitamin C content, whereas steaming preserves it. Cooking spinach can also reduce vitamin E levels but increase vitamin A content.

Tips for Consuming Spinach

Aim for one cup of spinach daily. Here are some ways to add more spinach to your diet:

  • Blend spinach into smoothies, pancakes, hummus, soups, vegetable chili, and tacos.
  • Add a handful of spinach as a base for meals.
  • Sauté spinach in extra virgin olive oil (EVOO) with bell peppers and crushed red pepper.
  • Steam and toss with olive tapenade or dairy-free pesto.
  • Toss spinach with a vinaigrette made from EVOO, balsamic vinegar, Dijon mustard, and dried Italian herbs.
  • Combine spinach in a smoothie with healthy fats like avocado or almond butter
