Everyone knows Popeye credited eating spinach for his superior strength. He often sang, “I’m strong to finich ’cause I eats me spinach.” This was because, at the time, Americans believed spinach contained a whopping 35 grams of iron. Well, there is actually only about 3.5 grams in just under a 1/2 cup of cooked spinach—which is roughly 20 percent of the recommended daily intake.
Little did they know though that spinach also contains a wealth of other vitamins and minerals that are instrumental in maintaining good health.
One such example is the antioxidant lutein, which makes spinach a heart-healthy food. In a 2017 study, researchers at Linköping University discovered that lutein played a role in lessening inflammation when they looked at immune cells from patients with coronary artery disease.
This was a significant finding because many people who live with heart disease endure chronic inflammation, which increases the risk of a heart attack.
