Call it the Popeye effect. While many associate spinach with its iron content, it’s actually the nitrates in those green leaves that give you a real-life power-up. Eating a diet rich in nitrates can potentially improve athletic performance, reduce cholesterol levels, and lessen the risk of heart disease, among other major pros:

Health Benefits of Spinach
Besides vitamins and nutrients, spinach is filled with nitrates and glycolipids, which may reduce inflammation. Here’s what else this veggie can do:
- Help your heart: The glycolipids in spinach promote the body’s production of nitric oxide (NO), which helps dilate blood vessels and reduce atherosclerosis.
- Improve cholesterol: The nitrates have the potential to significantly lower triglycerides, total cholesterol, and LDL levels.
- Keep blood glucose in check: Nitrates may also help lower blood sugar levels.
- Build muscle: Yep, nitrates again. They’ve been shown to enhance athletic performance by improving blood flow and muscle contractions.
- Reduce your risk of cancer: Spinach contains a chemical called N-oxalylglycine (NOG) that has a potential tumor-suppressing effect.
Now that you know why cartoon sailors down this stuff by the can, get your top questions on spinach, answered:
Should I drink green juice?
Adding spinach to drinks may be a healthful way to incorporate this nutrient-rich vegetable into your diet, especially if you’re on-the-go. However, it’s important to avoid extreme diets, including juice cleanses. Drinking only green juice for long periods of time can increase your risk of developing kidney stones and — in extreme cases —kidney failure due to the oxalates in spinach.
Cooking or soaking the spinach first reduces how much of this compound gets absorbed during digestion.
Should I eat it cooked or raw?
Boiling spinach may significantly reduce the amounts of those good-for-you nitrates, so raw or steamed is often the way to go. Pureeing spinach leaves may also increase the body’s ability to absorbthe healthful compounds lutein and beta-carotene compared to uncut spinach.
How should I prepare it?
Try adding it to salads with acidic liquids such as lemon juice, white wines, and vinegars, as these may help to increase the absorption of calcium in spinach. Also, adding fat to raw or steamed spinach helps to free up its beta-carotene content. No wonder Popeye’s girlfriend is named Olive Oyl!
