You may have noticed that Dr. Goglia prefers fish over most protein choices, and you may be concerned with the amount of mercury in fish. Nearly all fish contain traces of mercury, but fish such as shrimp, canned light tuna, salmon, pollock, and catfish are very low in mercury and can be eaten frequently without any problem.
However, Shark, Swordfish, King Mackerel, and Tilefish should be reduced to less than 12 ounces a week because of their high mercury levels. If you eat more than the recommended fish intake for the week, don’t worry because one week will not change the body’s methyl mercury. Try to cut back or the next week or two.
