What’s New and Beneficial About Swiss Chard

  • swiss chardWe’ve become accustomed to thinking about vegetables as great sources of phytonutrients. Indeed they are! But we don’t always appreciate how unique each vegetable can be in terms of its phytonutrient content. Recent research has shown that chard leaves contain at least 13 different polyphenol antioxidants, including kaempferol, the cardioprotective flavonoid that’s also found in broccoli, kale, strawberries, and other foods. But alongside of kaempferol, one of the primary flavonoids found in the leaves of chard is a flavonoid called syringic acid. Syringic acid has received special attention in recent research due to its blood sugar regulating properties. This flavonoid has been shown to inhibit activity of an enzyme called alpha-glucosidase. When this enzyme gets inhibited, fewer carbs are broken down into simple sugars and blood sugar is able to stay more steady. It makes sense to think about chard as a vegetable whose flavonoid phytonutrients are unique and may offer special benefits for blood sugar control.
  • Like beets, chard is a unique source of phytonutrients called betalains. In the betalain family are found reddish-purple betacyanin pigments as well as yellowish betaxanthin pigments. Both types can be found in chard! In the reddish-purple stems of chard and the reddish-purple veins in the leaves, scientists have identified at least 9 betacyanin pigments, including betanin, isobetanin, betanidin, and isobetanidin. In the yellowish stems and veins, at least 19 betaxanthin pigments have been identified, including histamine−betaxanthin, alanine−betaxanthin, tyramine-betaxanthin, and 3-methoxytyramine−betaxanthin. Many of the betalain pigments in chard have been shown to provide antioxidant, anti-inflammatory, and detoxification support. The detox support provided by betalains includes support of some especially important Phase 2 detox steps involving glutathione. So you can see that in the case of chard, beauty is far from just skin deep!
