How many ounces of tuna should pregnant and lactating women limit their intake to per week?

Pregnant and lactating women are often advised to limit their intake of certain types of fish, including tuna, due to concerns about mercury levels that can impact fetal and infant development. The recommendation for these women is to consume up to 6 ounces of tuna per week. This amount strikes a balance between the nutritional benefits of fish, such as omega-3 fatty acids, which are important for both mother and child, while minimizing the risk of mercury exposure. Eating more than this recommended limit can increase the likelihood of mercury accumulation in the body, potentially leading to adverse health effects. Thus, the guideline of 6 ounces helps ensure that pregnant and lactating women can safely enjoy tuna without increasing their risk of mercury-related complications.
