How important is fish?

Answered on August 19, 2014
Created October 24, 2011 at 3:53 PM

I ask this for two reasons. One is because fish is one of the few foods that I really am physically unable to eat. It inevitably triggers my esophageal stricture*, whether raw or fresh. My holistic neurologist thinks that it may be the level of certain minerals, since iodized salt also triggers the ES -- but I can manage small amounts of kelp, where the iodine is held behind stronger cell walls.

The 2nd reason it came up for me deals with "landlocked" populations, where fish wouldn't have been particularly common. How did they handle not having access to fish nutrients/fish oils?

*The ES developed after an abdominal stabbing that partially separated my esophagus from my stomach -- when it was re-attached, there was scar tissue that, over the past 30 years, has been affected by my MS and become a reactive stricture.

I'm guessing there was a long transit time. What does drying do to the omegas?

Probably drying them

Where they like drying them or carrying them in crates of water?

How where these trade routes persevering the shellfish on their transit from the coast to the center of Africa?

That ALA is not that effective, thats speculative.

Do you have the same response to Nordic fish/cod liver liquid or capsules? I don't want you to get ill but just wondering....

In your case, I'd say it's not necessary at all.

Actually, I crave liver and most organ meats, and usually eat organs (grass-fed beef/forage-fed pork/forage-fed chicken) several times a week. I also eat plenty of forage-fed eggs. (informationally, I don't really use the term "pastured" for chickens allowed to roam and eat what they please -- because grass is only a portion of what they eat when allowed to forage at will. Same goes for pigs.)

"abdominal stabbing"? Someone stabbed you?

Some of the earliest evidence for trade comes from shells found inland, so people inland did get some seafood from trading.

But they also got similar nutrients or needed less of them because of:

  • meat grazing on iodine-rich grasses
  • not eating much omega-6

I would limit omega-6 intake, eat a lot of grass-fed meat, and eat some plant-based omega-3 (ALA, not as effective as DHA, but better than nothing) or algal DHA if you feel you need it.

Because we have heretofore been unable to deplete the trace minerals in the oceans, eating ocean creatures is a great way to access those minerals in a bioavailable form. You won't become deficient in fish, but you may continue to be deficient in a trace mineral that you are unaware of. You could take a zinc supplement, but maybe you're lacking chromium etc. If you eat liver and other organs, you'll probably be OK, but for those who don't eat liver, I think ocean creatures are an advantageous addition to the diet. Oysters are great for zinc, mussels for manganese and clams for iron. All three are great for B12, selenium and iodide. If you eat a lot of 100% grass-fed muscle meat, but the animals are grazing year after year in the same paddocks, their absorption of trace minerals will be far less than would have occurred for wild deer hunted by your ancestors.

As far as omega-3s go, I don't think supplementation or fish consumption is necessary if one eats pastured egg yolks in sufficient quantities.

I think fish is more important today to humans than it was to humans 10000 yrs ago. Omega threes are tough to come by in a processed food world

First it's important to state that I don't know.

However, personally I don't go out of my way to buy or eat fish nor do I supplement with n-3's.

One problem with fish is it is pretty toxic nowdays. Furthermore, you need to make sure its not farmed. Thomas Levy recommends no more then twice a month for omega-3 because of those toxins. I can of tuna has more mercury then vaccines. Tuna mercury overdose is not unknown. The worst are the fishes on the top of the food chain.

I eat it once a week or so. I take lots of C after it, and selenium every day which helps remove mercury and other sh*t.

Organic flax oil or walnuts might be good alternative. Its not certain how much of ALA is converted to DHA and EPA and it depends on age. There are claims from 2%-10%. With aging you have delta-4-desaturaze diminishing which is one of the steps in DHA creation.

Some people, like Ray Peat, Brian Peskin and some others claim fish oil is toxic. Peskin claims that ALA is the only thing we should eat and let the body determine alone when and where it needs it converted into DHA (he calls it parent omega 3). I don't think they are correct and there is some big cherry picking in Peskins papers.

So, its probably best to supplement fish oil and eat fish sometimes because there are less toxins in supplements - 1g DHA/EPA/ALA per day seem to cover all basis. However, supplements can become rancid quickly so you need to be careful.

How important it is ? Very: from dementia, over immunity, over cvd, to insulin resistance and gingivitis.

I don't like fish, although I can deal with high-quality canned tuna. As a kid, I had to eat the fish we caught as a staple of my diet and as an adult, the taste just puts me off. If you don't want to eat it, don't eat it, just make sure the rest of your diet is in order. No one has ever died from "fish deficiency."

I don't know if you are able to swallow pills, but if so have you considered fish oil or cod liver oil capsules?

You will be fine without fish however you will want to get some omega 3 on your diet
