                                According to research published in the National Library of Medicine, Swiss chard is a highly nutritious leafy green, but its high oxalate and vitamin K content means it is not suitable for everyone. Individuals with pre-existing conditions like kidney stones or those on blood-thinning medication should exercise caution or avoid Swiss chard entirely.
