Arthritis is affected by dietary deficiency.
Healthy bone is made from calcium (and some magnesium) and phosphorus. Phosphates are common in our diet so we do not need supplements. Calcium is now being recommended by Government health departments including the US, Canada, Australia and UK for both men and women as they age. How much to take?
Vitamin D pushes calcium into bones. There is a blood test for lack of vitamin D. More on vitamin D.
Cartilage is the soft cushion overlying bone. Each joint has two or more bony surfaces covered in cartilage rubbing together as the joint moves. Cartilage is made of a fibrous mesh with a filler of mierals. It combines strength and some flexibility. It is living tissue, being repaired by cells called chondrocytes.
Joint fluid is a lubricant and a nutritive medium. It lubricates the joint surfaces. It contains minerals and sugars used in the production and repair of cartilage. The main ingredient is HYALURONIC ACID.
Joint fluid and cartilage need minerals and sugars (glyconutrients) for efficient use. Lack of these substances advances osteoarthritis. More on glyconutrients.
