What are substitutes for fish in the Glow15 program?

You can replace fish for any of the other healthy protein sources and fats discussed in the book (fish contain both, so be sure to include a variety of both fats and protein in your meals, keeping Low day protein requirements in mind). This might be pastured poultry, grass-fed beef, eggs, wild bison, nuts, seeds, etc. You might also consider taking a high quality fish oil if you won't be eating fish; we recommend BioAlaskan Omega 3.
