Potential Side Effects Linked to Chard s High Oxalate Content

Like spinach, rhubarb, purslane, and some other green leafy superfoods, Swiss chard contains significant amounts of oxalates. In people with kidney problems, foods that contain high levels of oxalates may lead to severe health complications. In addition, people with certain medical conditions, such as Primary Hyperoxaluria and Enteric Hyperoxaluria, may be advised to limit their dietary intake of oxalate rich foods, including Swiss chard and red chard, and to rotate green vegetables in their diets.
