For years we have been told to eat more fish as it is the healthy choice. Now it appears eating fish may not be the best for people with osteoarthritis as it contains high levels of zinc.
The study was done by Professor Jang-Soo Chun (a well respected researcher in Molecular and Cellular Biology so this the quality of the research is not in question) of the Gwangju Institute of Science and Technology in Korea.
You can read the full story at the Daily Mail.
Should You Reduce Your Zinc Intake for Your Osteoarthritis Pain?
No please don’t jump in and get carried away and start cutting all seafood and other zinc rich sources out of your diet.
For starters this study has only been done on mice!
Also these foods have health benefits. For example one of the foods they mention is salmon. Salmon is high in Omega 3 which has been shown to benefit our joints and our cardiovascular systems. It is also low in fat and keeping your weight down is important.
A Bit About Zinc
Zinc, like all trace minerals, are important in our diet. The key to them, as with anything is not to take it in excess. The current recommendation for the daily recommended amount (RDA) of zinc can be viewed here in full but for adults the daily amount is 11mg for men and 8 for women. This information also points out that zinc cannot be stored so we need to take it daily.
These are a few of the things it is involved in:
- Cellular metabolism.
- Required for the catalytic activity of approximately 100 enzymes
- Immune function
- Protein synthesis
- Wound healing
- DNA synthesis and cell division
- Supports normal growth and development during pregnancy, childhood, and adolescence
- Required for proper sense of taste and smell
So all in all a pretty important little mineral!
All in all I consider this to be typical sensationalising reporting of an early stage research study and I wouldn’t take it too seriously yet.
