Vitamins for restoration of cartilage tissue: a complete guide for the nutrition and health of the joints
Cartilage fabric, an elastic and strong structure lining the ends of the bones in the joints, plays a vital role in ensuring the smoothness of movements and depreciation of loads. Damage or degradation of cartilage caused by injuries, age -related changes, excessive loads or inflammatory processes leads to the development of various joint diseases, such as osteoarthritis. Optimal nutrition, rich in vitamins and other nutrients, is a key factor in maintaining the health of cartilage, slowing its destruction and, in certain cases, stimulating its restoration. This detailed guide considers key vitamins and nutrients necessary for the health of the cartilage, their role in the body, sources in food and methods of their use to maintain joint health.
Chapter 1: Fundamentals of the health of cartilage tissue
Cartilage tissue, consisting of cells called chondrocytes, and intercellular substance, rich in collagen, proteoglycans and water, is a unique tissue that does not contain blood vessels and nerves. Chondrocytes are powered by diffusion of nutrients from the synovial fluid surrounding the joint. This explains the slow process of restoration of cartilage and its vulnerability to damage.
1.1. The composition and functions of the cartilage:
- Collagen: The main structural protein of cartilage, providing strength and elasticity. There are several types of collagen, but type II collagen is predominant in cartilage.
- Protooglic: Molecules consisting of protein and glycosaminoglycans (GAG), such as chondroine sulfate and keratan sulfate. Protelyglycans hold water in cartilage, providing its amortizing properties.
- Chondrocytes: Cells responsible for the synthesis and maintenance of the intercellular substance cartilage.
Functions of cartilage:
- Depreciation: Reducing the shock load on the bones while driving.
- Ensuring smoothness of movements: The smooth surface of the cartilage reduces friction in the joints.
- Structure support: Maintaining the shape and stability of the joints.
1.2. Factors affecting the health of the cartilage:
- Age: With age, the synthesis of collagen and proteoglycans decreases, which leads to thinning and weakening of cartilage.
- Injuries: Damage to the joints, such as stretching, dislocations and fractures, can damage the cartilage and lead to the development of osteoarthritis.
- Excessive loads: Repeating movements and high loads on the joints, especially among athletes and people with overweight, can accelerate cartilage wear.
- Inflammatory diseases: Rheumatoid arthritis and other inflammatory diseases can destroy cartilage tissue.
- Genetic predisposition: Some people have a genetic predisposition to the development of joint diseases.
- Malnutrition: The deficiency of vitamins and other nutrients can negatively affect the health of the cartilage.
Chapter 2: Key vitamins for the health of the cartilage
The optimal consumption of vitamins plays an important role in maintaining the health of cartilage tissue and preventing its destruction.
2.1. Vitamin C (ascorbic acid): powerful antioxidant and key to collagen synthesis
Vitamin C is a powerful antioxidant that protects cartilage cells from damage to free radicals. It also plays a key role in the synthesis of collagen necessary for the strength and elasticity of cartilage.
- Role in the body:
- It stimulates the synthesis of collagen: Vitamin C is a cofactor of enzymes involved in the synthesis of collagen. It is necessary for the formation of hydroxyproline and hydroxylizine, amino acids necessary for the stability of the collagen molecule.
- Protects from free radicals: vitamin C is a powerful antioxidant that neutralizes free radicals that form as a result of metabolic processes and environmental exposure. Free radicals can damage the cartilage cells and contribute to its destruction.
- It supports the health of the immune system: vitamin C strengthens the immune system, which helps to protect the body from infections and inflammatory processes that can negatively affect the health of the joints.
- Sources in food: Citrus fruits (oranges, lemons, grapefruits), berries (strawberries, blueberries, raspberries), kiwi, pepper (Bulgarian pepper, chili), broccoli, spinach, tomatoes.
