According to Traditional Chinese Medicine, Jing refers to our genetic blueprint. Jing is passed from parents at conception. In order to increase fertility and pass along strong Jing to our children, a healthy lifestyle is important. Among other things, eating healthy food, getting enough rest and managing stress play roles in supporting Jing. Jing is stored in the kidneys. In Chinese medicine, the kidneys are associated with the reproductive system. Therefore, when thinking of foods to support your fertility (i.e., to impact the quality of your eggs or your sperm) nurture your Jing.
