Can you eat too much Swiss chard?

Although Swiss chard is extremely healthy, it should be eaten in moderation. Eating too much can lead to side effects such as:

  • Kidney stones: Swiss chard contains antinutritive oxalates, which may increase urinary oxalate excretion and increase the risk of calcium oxalate stones.
  • Blood clotting: If you are on blood thinners, you may want to avoid Swiss chard due to its high vitamin K content, which plays a role in blood clotting.
  • Allergy: If you are sensitive to grass pollen, you should avoid eating Swiss chard because inhaling vapor from boiling the vegetable may trigger rhinoconjunctivitis.

How can I cook Swiss chard?

Swiss chard may be cooked in a variety of ways:

  • Boiling: Cover the chard with water and cook for 1-2 minutes, or until tender, over medium heat. Leaves and stalks should be cooked separately because the stalks take longer to cook.
  • Steaming: Add the stalks first, followed by the leaves 3-4 minutes later.
  • Sautéing: Sauté th stalks in olive oil for 2-3 minutes before adding chard leaves.
  • Microwaving: Rinse the chard in cool water. Microwave in 1-minute intervals until the leaves are wilted.

It is important to remember, however, that cooking Swiss chard can reduce or degrade some of the nutrients. In order to reap the most health benefits from Swiss chard, it is best to eat raw or very lightly cooked.
