Avoiding raw meat is essential for one’s joint condition.
This is one of the main reasons for persisting facet syndrome,
and with time for disabling osteo-arthritis (called arthrosis in Europe.)
Progressive deformity with advancing age of joints and vertebral spine (scoliosis, cyphosis) are due to deficit in Vitamin B12 and folic acid, which end up in degeneration of posterior columns of spinal cord. (neuropathic joints and spine)
In this situation (skeleton of third age), vitamin B12 should be added parenterally.
