You all probably know that eating fish higher on the food chain poses a greater risk of ingesting too much mercury. What I don't understand is the "guidelines" for eating fish. You hear about recommendations for pg women to eat less fish (b/c of mercury exposure to the fetus) and that we shouldn't eat more than x amt of servings per week.
Does that mean that mercury is excreted by the liver over time so that you can "regularly" expose yourself to low levels of mercury-contaminated fish and be safe? I thought mercury was cumulative? Certainly I would imagine that an onslaught of mercury is worse that minute amts over time. But isn't it a heavy metal that accumulates in the body?
Thank you for any info.
