hi,

what do you think of this by Jack Kruse:

http://jackkruse.com/brain-gut-5-paradigm-drifts-paradigm-shifts-epi-paleo/

is there any limit to how much fish we can eat? any figure to how much or again, no limit?

i want to eat as much fish as i do meat, but im worried about toxins and mercury or is that all nonsense?

thanks paleos

Jack Kruse is often not a reliable source of information as was the case with this photo he claimed was of himself showing his own progress and he welcomed all the praise he received http://i.imgur.com/Wp5hH.jpg Also this x-ray image he also claimed was of his own hand http://i.imgur.com/Epd9P.jpg Both images were found to be taken from images available on the internet. People who make such false claims so casually tend not make reliable sources.

Raydawg, the entries on the Paleodrama site are written by multiple people, so it would seem that many have objections to Kruse. It's tough to read more than a few sentences of his blog without coming across glaring exaggerations or inaccuracies, so I'd rather seek nutrition advice from someone more reputable.

Yes, I eat some sort of seafood everyday ('cept the odd day out). I can't fathom a reason to restrict seafood categorically, even with specific species to avoid in frequency.

@Alex that site is meant as a platform from which to discredit and attack Richard Nikolay and Jack Kruse. The person who runs it has a personal grudge. This post best embodies the spirit in which it is written: http://paleodrama.tumblr.com/post/30080184966/duty-calls - it isn't the spirit of helping one another on our paths, it is the spirit of spite, the spirit of picking nits and using them to attack your "enemies" from a position of fear rather than debating them face to face in the open.

According to this link, selenium doesn't protect against mercury toxicity: http://suppversity.blogspot.com/2012/08/mercury-in-fish-not-harmless-regardless.html

Who rejects the fact that living in coastal ecosystems with catchable aquatic resources, consumed these resources? Every published diet book or recipe book on the paleo diet so far includes fish and sea food.

Mercury is more of a risk in large, top-predator fish like tuna. Not a risk in smaller fish low on the food chain, such as anchovies, sardines, smelt, trout, salmon.

Jeremy Piven (Ari Gold for those in the know) claims to have contracted Epstein Barr virus and other ailments due to 20 years of eating fish daily. Mercury poisoning was also a factor. I eat fish at least twice a week, whether in sushi or standalone, seems to be a good balance for me. Is there any reason as to why you want to consume as much fish as you do meat? What's the reasoning?

^ You might find this thread useful. There is speculation that the selenium in seafood protects against mercury toxicity. You can always choose fish lower on the food chain as well, like shellfish and sardines for staples.

I eat fish every day. I purchase wild caught always, and eat fish with abandon. However, I do keep tabs on how much big, long-lived, top-of-their-food-chain fish I eat (e.g. tuna, swordfish), as they are most likely to have highest levels of metals. Small, young, oily fish are where it's at -- highest n-3 FA per weight, and least mercury.

Eating fresh, the easiest thing to do is buy frozen smelt. Smelt and sardines are often available fresh, as well.

Eating canned, you are likely to find sardines and anchovies, and while I like a small amount of canned anchovies for flavor, I'm just not a fan of canned fish.

You would do well to read Remko Kuipers, Stephan Cunnane, and Michael Crawford's work to make your own assessment in these areas. Seminal work. Dr. Kuipers was an AHS 2012 speaker who few people attended his lecture sadly.

Here's a paper from (Kuiper's) Dutch researchers entitled "A multidisciplinary reconstruction of Palaeolithic nutrition that holds promise for the prevention and treatment of diseases of civilisation".

Among other things it says in the abstract:

There is ample evidence that our ancestors lived in a land???water ecosystem and extracted a substantial part of their diets from both terrestrial and aquatic resources. Rather than rejecting this possibility by lack of evidence, the default assumption should be that hominins, living in coastal ecosystems with catchable aquatic resources, consumed these resources. http://journals.cambridge.org/action...54422412000017

Also he goes into just how protective selenium and EPA and DHA are (or are not). Anyway, it's a good resource IMO.
