A frosty mug of beer or ruby-red glass of wine just wouldn't be the same if the liquid was murky or gritty. That's why producers of alcoholic beverages usually filter them. But in a study appearing in ACS' Journal of Agricultural and Food Chemistry, researchers report that a material often used as a filter could be transferring heavy metals such as arsenic to beer and wine. They also found ways to possibly limit this contamination.
Chronic dietary exposure to high levels of arsenic, lead and cadmium can endanger health. Therefore, the U.S. Food and Drug Administration (FDA) has set limits on these heavy metals in foods and beverages. Although some studies have reported elevated levels of the contaminants in wine and beer, researchers aren't sure how the metals are ending up in these beverages. Benjamin Redan, Lauren Jackson and colleagues wondered if the diatomaceous earth (DE) used to filter beer and wine could be introducing heavy metals, and if so, whether altering the filtering conditions could reduce the transfer.
