Popeye’s power vegetable can do good things for your body, too -- like fortify it against blood sugar problems.
That’s right. Eating spinach -- and other leafy greens -- was associated with a lower risk of type 2 diabetes in a recent study. Spinach is known as a rich source of iron and calcium. According to the USDA, a 180 gram serving of boiled spinach contains 6.43 mg of iron, whereas one 6 oz. (170 gram) ground hamburger patty contains at most 4.42 mg. Thus spinach does contain a relatively high level of iron, compared to other vegetable and meat sources.
Spinach may reinforce the body on multiple fronts. First, it’s got a low glycemic load, so it doesn’t dramatically affect blood sugar levels when you eat it. Second, it’s a good source of magnesium, a mighty mineral associated with lower type 2 diabetes risk. Third, spinach is packed with alpha-lipoic acid, a disease-shielding antioxidant. And fourth, it’s low in calories and rich in fiber.
Ultimately, the bioavailability of iron is dependent on its absorption. This is influenced by a number of factors. Iron enters the body in two forms: nonheme iron and heme iron. All of the iron in grains and vegetables, and about three fifths of the iron in animal food sources (meats), is nonheme iron. The much smaller remaining portion from meats is heme iron.
