Walnut kernels are very nutritious, helping to strengthen the stomach, nourish the blood, moisten the lungs, calm the mind, and moisturize the skin and darken hair. Walnuts soaked in vinegar are both disease-preventive and health-preserving.
However, the drawback is that walnut kernels are high in oil content and can be difficult to digest in large quantities. Wang Huiqin, Chief Nutritionist at the Nutrition and Dietetics Department of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, says that vinegar can aid digestion, whet the appetite, and also detoxify. It is a good idea to make a dish of vinegar-soaked walnuts, which is both delicious and not greasy.
Select a clean, sealable glass jar. Then, mix 250 grams of walnut kernels with 500 grams of vinegar in the jar and seal it. It can be eaten after 10 days. When eating, be mindful to not just eat the walnut kernels. It is best to use a small household spoon to serve a portion each time, consuming both the walnuts and the vinegar. Director Wang says that vinegar-soaked walnuts, like vinegar-soaked peanuts, are also a great appetizer. It not only strengthens the stomach and aids digestion but also prevents disease and promotes health. Additionally, because walnuts can "moisturize the skin and darken hair," they are suitable for both the young and the old.
