Eating Duck in Mid-Autumn Season to Moisturize Yin and Prevent Autumn Dryness
In many parts of China, there is a custom of eating duck during the Mid-Autumn Festival. Regardless of cultural background, duck’s nutritional value and health benefits make this practice quite reasonable. Autumn is when ducks are fattest and most flavorful. More importantly, duck is a cooling food that nourishes yin, soothes the stomach, promotes urination, and reduces edema—perfect for preventing autumn dryness.
Duck meat is highly nutritious, containing proteins, fats, carbohydrates, vitamins B1, B2, E, riboflavin, thiamine, potassium, sodium, chlorine, calcium, phosphorus, iron, and other components. The protein content in edible duck meat ranges from 16% to 25%, significantly higher than that in livestock meat. Duck fat content is moderate at about 7.5%, higher than chicken but lower than pork. It contains unsaturated fatty acids with high digestibility and absorption rates.
Besides rich nutrition, duck broth has anti-fatigue properties. Duck oil has relatively low cholesterol compared to other animal oils, with a favorable ratio of saturated, monounsaturated, and polyunsaturated fatty acids. Duck blood has benefits for blood replenishment and clearing heat and toxins.
TCM regards duck as a "medicine" and a top-grade tonic. Duck meat is sweet in flavor and cold in nature, benefiting yin, nourishing the stomach, tonifying the kidneys, eliminating weakness, reducing swelling, and relieving cough and phlegm. It assists in treating conditions like yin deficiency edema, weakness, summer heat exhaustion, constipation, anemia, and chronic nephritis. Those who are physically weak, recovering from illness, or prone to internal heat—especially those with low-grade fever, poor appetite, dry mouth, constipation, or edema—benefit greatly from eating duck meat. Elderly and children, who commonly suffer from yin deficiency, should also eat duck meat regularly.
Although duck is beneficial, overconsumption should be avoided, as excess animal protein may lead to arteriosclerosis. Duck meat has high energy content; fried duck leads to excessive calorie intake, which is detrimental to cardiovascular patients. Different constitutions absorb food differently—those with cold constitution should avoid excessive cold foods like duck. People with cholecystitis should also limit duck intake, as high-fat, greasy duck may trigger gallbladder attacks.
