27 vegetables high in calcium

Besides being an essential nutrient for the growth and maintenance of healthy bones and teeth, calcium plays an important role in blood clotting, weight management and muscle contraction.

When people think about calcium rich foods, the first thing that pops into their mind is usually dairy. However, there are quite a few vegetables that provide significant quantities of calcium.

Some of these vegetables are also high in compounds called oxalates, which bind to calcium, thereby preventing your body from absorbing some of it. Because of this, it is a good idea to eat a variety of the vegetables listed on this page, together with other calcium rich foods, in order to meet your daily needs.

Calcium requirements for people above the age of 4 range from 1000 mg to 1300 mg per day.

Below is a list of vegetables that are high in calcium.

Together with calcium, it is also an excellent source of vitamins A, C & K, some of the B vitamins, iron, magnesium and manganese. The oxalate content of collard greens is considered to be medium, meaning a fair amount of the calcium is available.

Collard greens are a cruciferous vegetable, which have been shown to have strong cancer fighting properties. Also this study found that eating steam cooked collard greens can help lower the risk of cardiovascular disease.
