Just a correction. A memeber posted that white spots on fingernails could be due to zinc deficiency. That is simply not true. People with high levels of Zinc have white spots as much as people with Zinc deficiencies. This is a common misconception and is not supported by medical studies.
Cecil has addressed exactly this issue.
Is this in regard to Cecils piece on punctate leukonychia?
Yah bastard quothz. At least you found the article.
