Trace amounts of heavy metals like arsenic can be found in many foods, as plants naturally absorb elements from the soil. This includes nuts, but studies show the levels are extremely low and not a cause for alarm for average consumers. The question of what nut has arsenic is more about understanding natural environmental processes than identifying a specific threat.

According to the World Health Organization, contaminated water used for irrigation is a primary way food crops, including nuts, are exposed to arsenic, a toxic heavy metal. This leads many to ask: which nut has the most arsenic and is it a cause for concern?
