Many of us want to eat more fish, but we're worried about too much mercury. While all of us should be concerned, women who are pregnant or nursing need to pay special attention. A handy chart from Consumer Reports ranks fish by amount of risk in each species.
The safest fish are shellfish like prawns, scallops and oysters (sorry Kosher friends), along with wild salmon and tilapia. The Consumer Reports chart disagrees with some of the FDA and EPA guidelines on tuna, suggesting we eat even less. The FDA has a list of all fish and mercury levels, but the Consumer Reports chart is easier to read. Expand the chart to the left to see it in full, and read the full report for more details at the link below.
