Although some research has claimed that salted eggs and pidan are "nutritionally rich alternatives of duck eggs products which will benefit the human health during consumption," keep in mind that salted eggs contain a lot of sodium so it is not advisable to eat too much of it. 1 salted egg yolk can contain about 680mg of sodium or 1/3 of your recommended daily intake, as well as over half of your recommended daily cholesterol consumption. Most salted egg yolk dishes use more than 1 egg yolk, so much as I love this traditional condiment, I wouldn't recommend eating them too often.
