Calories in Beet greens

What makes beet greens so powerful?

Beet greens are botanically the same species as Swiss chard (Beta vulgaris), sharing a common ancestor in the sea beet, a coastal plant native to the Mediterranean. While modern beets were selectively bred to enlarge their taproot, the greens were historically the primary edible portion of the plant for centuries. Ancient Romans and Greeks primarily consumed the leaves, using the roots mostly for medicinal purposes before larger-rooted cultivars emerged in the 16th century. Chemically, the vibrant stems and leaf veins contain betalain pigments—betacyanins and betaxanthins—which act as powerful antioxidants. These nitrogen-containing pigments are distinct from the anthocyanins found in most other red and purple vegetables. Unlike anthocyanins, betalains maintain their structural integrity and color stability across a wider pH range, which is why pickled beets retain such a vivid hue. The leaves themselves are rich in lutein and zeaxanthin, carotenoids that selectively accumulate in the human retina to filter damaging blue light. Because beet greens contain high levels of oxalates, naturally occurring organic acids, they can bind to calcium and reduce its absorption in the digestive tract.
