However I would advise against eating a diet too high in raw seafood(anything above 80% of your particular raw-animal food intake), given my own experiences.
That's surprising to hear Tyler. I thought you ate large volumes of seafood?! Although, the 80% you quoted could be considered most extensive of course!
Out of interest, along with noel, I'd be interested to know why you think this and what your negative experiences were?
Certainly, I do not personally find raw seafood at all satisfying and am usually MORE hungry an hour or so after eating it than I was in the first place! I also doubt it's validity as a paleo food consumed in any great quantity pre-civilisation besides regions and natives - such as the inuit - whose environment allowed or enforced it.
Following my own numerous bad experiences with raw seafood I eat it rarely and only after marinating. Tyler probably won't agree with this but I believe I've been a victim of a series of vicious seafood parasites which have made me violently ill. Perhaps I've just been unlucky or sourced poor quality fish/seafood. Whichever, it's certainly created a fear of raw fish/seafood for me. In 10 years of eating raw meats I've never had a similar problem and have never frozen or marinated my meats.
Noel, I would second Tyler's recommendations on marinating. For many years, I have marinated my fish overnight in freshly squeezed organic lemon juice. Unfortunately, this can prove a rather expensive hobby due to the high price of lemons (here in the UK at least). As Tyler stated, it does denature the protein but one's digestive system also does this so, perhaps, it may even be considered a form of pre-digesting. I would, however, also recommend that you persist with meat & fat as it will be the best longer-term source of sustenance and healing for you. Perhaps the circulation problems are aggravated by something else? There is, of course, a whole myriad of things which could cause and/or aggravate this. Is the meat/fat you're eating high quality grass-fed and grass-finished?
