Multiple studies on animals have shown that chard has unique benefits for blood sugar regulation. In addition, chard may provide special benefits in the diets of individuals diagnosed with diabetes. Although large scale human studies have yet to be conducted in this area, lab studies and animal studies show that syringic acid one of chard s premiere flavonoids has the ability to inhibit activity of an enzyme called alpha glucosidase. Alpha glucosidase is an enzyme used to break down carbohydrates into simple sugars. When this enzyme gets inhibited, fewer carbs get broken down and blood sugar is able to stay more steady. This blood sugar steadying process seems to be particularly true following a meal.
