Our Nonna’s friend, Angelo would bring us weekly bundles of chard throughout the growing season. Versatile at all stages of growth from spring to late fall, chard can be clipped early for fresh baby greens, the young stalks can be cooked like asparagus, the mature leaves cooked like spinach and larger/mature stalks added to fritters and frittatas.
Research has shown that chard leaves contain at least 13 different polyphenol antioxidants, including kaempferol, a cardioprotective flavonoid also found in broccoli, kale and strawberries. Another primary flavonoid found in the leaves of chard is syringic acid known for its blood sugar regulating properties. Shown to inhibit the activity of the enzyme alpha-glucosidase. When this enzyme gets inhibited, fewer carbs are broken down into simple sugars and blood sugar is able to stay more steady offering special benefits for blood sugar control.
Sometimes referred to as Swiss Chard, chard was first identified by a Swiss botanist (possibly accounting for its name). Known to the ancient Greeks and Romans it is wildly popular in the Mediterranean and in Italy Swiss Chard, (bietola) or coste as it is called by the Piemontesi, is a used to flavor soups, pasta, pizza, meatballs, sauces, strudel, served over polenta, as a contorno (side dish) sautéed and slightly wilted with extra virgin olive oil and garlic and in the making of a torta salata (savory pie).
