I had an interesting tidbit to share about wine. At a recent educational seminar, the instructor was talking about the heavy metal content in wine. He claimed that he could tell if the patient was a regular wine drinker by signature levels of certain heavy metals present in a blood test. After looking into it I found a study from late 2008 that tested heavy metal levels in wines from 15 nations. You can read the full article here.
The results showed that, of all 15 nations tested, only 3 countries had wine with safe levels of heavy metals: Argentina, Italy, and Brazil. All the other wines tested levels 50-300 times what was considered safe. The highest contaminations were from vanadium, copper, and manganese. Manganese accumulation in the brain is apparently linked to a higher risk of Parkinson’s disease.
Unfortunately, US and Californian wines were not included in the study. It would be interesting to see the results of further testing, and also to find out the source of the measured heavy metals.
