Drinking coffee with raw fish greatly reduces exposure to mercury, according to a new study released last week by researchers at the Université de Montréal. The study, published in the journal Environmental Research, also found that drinking coffee or tea while eating boiled or fried fish reduces mercury exposure to almost none.
“The magnitude of the effect was surprising,” said Marc Amyot, one of the lead researchers on the study. “We thought there might be a five-to 10-per-cent reduction (in the exposure to mercury). We don’t usually see such dramatic results.”
The study, which involved techniques that simulated human digestion, showed that coffee or tea ingested at the same time as raw fish — including tuna, shark and mackerel — reduced mercury exposure by 50 to 60 percent.
“This is what you call a provocative study,” Amyot told the Montreal Gazette. “It opens the door to more research.”
