I was browsing the archives and saw some negative bias towards pescetarians, based on what I would assume is the notion that a sea animal based diet is somehow deficient in essential nutrients that only land animals can provide. I am not fully pescetarian, because I do eat chicken, bison, and pork, but those amount to less than a pound a week combined, sometimes less than a pound every 2 weeks. I would say that over 80% of the animal products that I've consumed over the past year and a half are from seafood.
Are there some essential nutrients I can only get from ruminants? *Is there something wrong with a pescetarian paleo diet? I get bi-annual blood work do*ne, and b12 and vitamin D status are always well within range. As far as I can tell, seafood is preferable to ruminants because of the more bioavailable omega 3s (brain and cellular health), zinc (reproductive health), and iodine (thyroid health)....and of course protein for muscles. Seafood does not provide iron or carnitine (that I know of), but I am not anemic (I can still donate blood) and I eat spinach with provides iron and a very low phytic acid diet with virtually no coffee (diminishes iron absorption). Again, I do eat chicken and red meat, but only about 1x per week and not in large quantities (usually surf and turf with only about 4-6oz of meat). Right now I'm eating about a half dozen free range eggs a week too, but my egg consumption is inconsistent throughout the year.
Also, Do you have any other suggestions that I could use as a staple (i.e. fish/seafood that's low in mercury and PCBs and high in nutrition)? I've been eating a lot of shrimp, scallops, lobster, and canned sardines (Wild Planet, BPA free) as my staples. I also eat fresh and canned wild salmon (Wild Planet, BPA free cans), fresh ahi tuna, and light tuna packed in olive oil (Crown Prince BPA free, usually). I eat oysters 2-3x per week (out) and whitefish occasionally. I really like canned sardines, and probably average about a can a day but *I worry that the omega 3 is oxidized in the canned sardines- does anyone know if these concerns are warranted or not?
Thank you in advance for your thoughts and suggestions.
