I reccomend you read this article on Chris Kresser's blog, he really knows his stuff - : http://chriskresser.com/is-eating-fi...ot-eating-fish
I enjoy fish very much and usually stick to the less contaminated kind (wild caught salmon, marcareles, sardines). However, I often find the recommendation that it is fine to have two servings/week but not much more due to mercury and, what bothers me even more, PVC contamination. Is there any reliable source about how much is really safe?
Also, I once did some research back in my CW days. In order to reach the FDA recommended 'warning' levels of mercury in your system you'd need to eat 4 cans of tuna a week (average sized male). BUT!!!! That FDA level is ten times lower than actual harmful levels. So 40 cans of tuna/week. Kind of silly.
Be aware that mercury builds up in your system and very very slowly, if ever, is excreted.
Also, some people are very sensitive to it.
If you like fish and want to eat it more often, stick with fish that are lower on the food chain. The bigger predators will have higher concentrations of it.
What are the signs of Mercury building up in the body?
Mercury is removed by the body easily. Selenium carries it out. Where is selenium easily found? FISH.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
Friend it is completely on you how much fish you can digest easily without any problem. Because you can guess or make idea how much you can digest not any one and if you are asking for this how much is good for health than eat as much as you can there is problem of eating fish but after eating fish don't drink milk.
