The components of articular cartilage are mainly hyaluronic acid and collagen fibers, so when articular cartilage is damaged, we should pay attention to supplementing more protein and glucosamine, etc. We should also supplement various foods rich in zinc, which is mainly found in animal foods and very little in plant foods and fruits, such as lean meat, liver, fish, shrimp, crab, egg yolk, etc. In addition to this, it is important to supplement with proper protein and glucosamine, which can have the effect of strengthening bones and reducing joint damage. Also pay attention to the intake of calcium, if the intake of calcium is not enough, the bone structure is prone to become loose, fragile, the fall impact during the exercise process will easily cause fractures and other bone damage, causing the joint surface joint cartilage friction reduction. Long-term strenuous exercise will accelerate the wear and tear of the joints, especially the cartilage that plays a role in cushioning vibration and reducing friction, so pay attention to supplementing the nutrients that nourish cartilage and reduce cartilage wear, glucosamine.
