Nutrition and joint health

Joints health is affected by four main issues:

  • How much physical activity we do
  • Our past diet history
  • How much we weigh
  • How well we age.

Research has found that the risk of developing osteoarthritis (OA) in the knee increases with rising weight. Studies of overweight subjects found reducing weight by 5kg reduced the need for knee surgery by 24%.

Nutrition plays a role in collagen, bone and cartilage formation.
The key ingredients to good bone health include: calcium, vitamn D, phosphorus, protein, vitamin C and zinc.

If you are keen to assess your current intake of these nutrients and learn how to maximise your intake naturally, without the need for dietary supplements, then contact us now for an assessment.
