12. Eat fish once a week and vary your fish consumption.
All fish are a good source of protein and low in saturated fat, and some types of fish like salmon and tuna are very high in omega-3 fatty acids. Many people now question the safety of eating fish because of the potential for contamination by such pollutants as mercury and PCBs. However, once-a-week consumption should be enough to meet your requirement for omega-3s while minimizing your exposure to pollutants. Varying the type of fish you eat will also help minimize your exposure to any pollutants. If you want to check whether a specific fish is high in mercury, you can visit this website by the FDA. The Environmental Protection Agency also has fish advisory information here. If you are pregnant or nursing, or if you are feeding a small child, the recommendations are more stringent than for most people, so please check the advisories.
