The nutritional value of duck eggs

Duck eggs are highly nutritious and offer a rich source of essential nutrients, comparable to chicken eggs. They contain protein, phospholipids, vitamins A, B2, B1, D, as well as minerals like calcium, potassium, iron, and phosphorus. Compared to chicken eggs, duck eggs tend to be more oily and may carry a higher risk of contamination due to the environment in which they are often produced. However, when cooked for at least 15 minutes or baked properly, they are safe to eat. When boiled, the white turns blue, and the yolk becomes a vibrant orange. Only very fresh duck eggs should be consumed, and they are not recommended for making egg white foam. Nutritional analysis shows that duck eggs have a similar protein content to chicken eggs, but they are richer in minerals, especially iron and calcium. These nutrients can help prevent anemia and support healthy bone development. Duck eggs are generally suitable for most people, but there are some exceptions. They are beneficial for individuals with coughs, sore throats, or bleeding conditions. However, those with spleen and stomach deficiencies, cold-damp diarrhea, or qi stagnation should avoid them. People who are currently ill, suffering from nephritis, or dealing with cancer should also refrain from eating them. Additionally, individuals with hypertension, hyperlipidemia, arteriosclerosis, or fatty liver disease are advised to limit their intake. Duck eggs should not be eaten with salmon, plums, or mulberries, as these combinations may cause digestive discomfort. In traditional Chinese medicine, duck eggs are considered sweet, salty, and cooling. They are believed to nourish the yin, enrich blood, and improve skin health. They are commonly used to treat symptoms such as fever, cough, sore throat, toothache, and excessive mucus. According to ancient texts like *The Minor Forest of Medicine*, duck eggs are said to clear heat from the lungs and soothe the throat. In *Herbal Materia Medica*, it is mentioned that they help reduce phlegm and relieve sore throat. Tao Hongjing noted that duck eggs should not be combined with meat or plum-based foods. Other historical records suggest that duck eggs can help with scarring and are useful in dietary therapy for certain ailments. However, overconsumption may lead to discomfort, especially in pregnant women or children. It is also noted that duck eggs should not be eaten with meat or plum products, as they may be harmful to the body.
