Food Network actually mapped out the way to a healthy diet, including the amount of fish you should be aiming for. According to them, the “sweet spot,” so to speak, is twice a week. They further suggest that how you get those fishy nutrients is all up to you. The writer, a mother, uses tricks like tuna and crackers and fish tacos, but you can also try fish sticks for pickier eaters.
The FDA actually suggests a different form of measurement. Instead of days per week, they recommend a specific amount — eight ounces per week, to be exact. They note that the eight ounces will provide needed “protein, healthy omega-3 fats (called DHA and EPA), more vitamin B12 and vitamin D than any other type of food, iron … [and] other minerals like selenium, zinc, and iodine.” They also warn against varieties with too much mercury, which can have less-than-healthy effects on your system.
