Zinc levels should be recorded in people with arthritis

The amount of zinc and cadmium in the blood ought to be tracked in people with osteoarthritis and rheumatoid arthritis, as the metals could impact on treatment choices.

A new article in Review Nutrients looked at the effects that zinc (a nutritionally essential metal) and cadmium (a non-essential metal) have on the immune system, inflammation and metabolism.

We already know that zinc decreases in the blood of people with rheumatoid arthritis. But we don’t know if this is because people don’t get enough zinc in their diets or if the inflammatory response decreases the zinc.

Cadmium interferes with zinc’s functions. And inhaling cadmium may triggers a form of nodular rheumatoid arthritis.

The authors of the review conclude that “both metal ions should be monitored routinely in arthritic disease and that there is untapped potential for prognosis and treatment.”

A little more about zinc

The amount of zinc we need is about 9.5mg a day for men and 7mg for women (aged 19 to 64 years). We should be able to get all the zinc we need from our daily diet. Remember not to take high doses of zinc, as it can reduce the amount of copper the body can absorb, leading to anaemia and weakening of the bones. Good natural sources of zinc include:

  • Meat
  • Shellfish
  • Dairy foods
  • Beans
  • Chickpeas
  • Lentils
  • Quinoa
  • Cashew and walnuts
  • Seeds including chia, ground linseed, hemp and pumpkin
