Why do olive and fish oil make me sick?

Answered on September 12, 2014
Created March 17, 2010 at 4:38 AM

For years I had a peculiar reaction to salmon: I threw up the oil. Just the oil. Every time. In the past several years, I have been able to greatly reduce this by only eating wild salmon, which makes me think that it was the oil in the farmed salmon that was the culprit. I do still feel nauseas whenever I eat oily or "rich" fish, but I don't seem to actually get sick (though I do know not to overdo it!).

I also always feel sick after eating a dish rich in olive oil. I am posting tonight because we just had a caesar salad for dinner, and I feel awful.

If all of this isn't tricky enough, I am on a regimen of massive amounts of fish oil (omega 3's plus fermented cod liver oil, for depression), and these are totally fine on my stomach.

Why can I eat butter by the spoonful and anything doused in lard, but these other fats make me feel ill?

Melissa, thanks for posting about the histamine level increasing. That's most useful. Old olive oil can be used to make soap. :)

Flax oil goes rancid fairly quickly too.

Flax provides short chain omega-3 which is poorly converted to the longer chain omega-3 present in fish/krill.

If you are going for a non-fish source, krill oil or algal DHA is a better choice.

Olive oil has some PUFAS, which degrade rather quickly. Most people don't seem to know this and they buy olive oil in clear containers and don't bother shielding it from the light. A properly stored cold pressed olive oil is a world away from the dreck that most restaurants and people use. It also has polyphenols that some people are sensitive to.

Non-fresh fish can have high levels of histimine, which many people are sensitive to. If you want to know more about the possibilities of what you are sensitive to, check out the Failsafe website.

I personally do fine with fermented CLO or fish oil stored carefully (my co op has a brand that is stored in the fridge), but the pills that you get from a shelf make me sick.

Addendum: I am personally sensitive to some sort of degradation I think, but I'm not sure if it's rancid PUFAs, histimine, or something else. All I know is that if I let me meat or fish stay too long in the fridge, cook things for a long time in a crockpot, or eat canned fish it makes me feel off. My solution for the crockpot problem is to cook with wine. I find that protects the meat and I feel fine eating it.

Because neither fish or olive oil are all that healthy!

Couple of relevant posts by Peter @Hyperlipid on the subject:

http://high-fat-nutrition.blogspot.com/2009/09/palmitic-acid-based-food-vs-olive-oil.html

"Finally my view about olive oil:

Not as bad as corn oil but butter is better!"

http://high-fat-nutrition.blogspot.com/2009/12/cirrhosis-and-fish-oil.html

"Oh, and fish oil: I think some DHA is a good idea, it has lots of uses in cell membranes. Drinking it by the tablespoon is not something I would recommend! Getting 30% of your calories as fish oil is OUT. Do not do this."

Farmed salmon is fed granules of mysterious feed which probably contains ingredients that set you off. Stick to wild.

You are right to be suspicious of farmed fish as much of it contain large amounts of omega 6 along with the omega 3 (that's what happens when you feed fish corn). As for your problem with unsaturated fat, I don't know. Perhaps you are getting rancid oils, as Melissa said...

I've found walnut oil to be very pleasant. I get sick on olive oil and fish oil also.

Olive oil has a significant amount of salicylic acid in it and that could be certainly irritating your stomach and mouth like it does me. Fish oil might be irritating like many have stated above because of the ingredients the fish was fed, how it was raised, or also how the fish oil was derived from the fish or processed. Depending on how much fish oil you eat though: the Omega 6 content is not a significant amount in most amounts of fish oil consumed so it probably isn't the issue but it could certainly be. Also about olive oil: do not eat olive oil from a plastic bottle. It always tastes very nasty and there has been substantial evidence that olive oil heavily leaches plastic from the container it is in. Flaxseed has a large amount of xenoestrogens in it which could cause hormonal imbalance: though studies said that a couple servings a day are fine these studies are not long term.

Avoid butter because it contains natural hormones, not the hormones you always hear about: the hormones that are from the cow or goat or whatever animal that are meant for the baby that cause significant problems with the body and cell division, or cancer.

I recommend for fats just fatty meat or fish, tallow, or a nut oil like macadamia nut oil from a producer where not much heat is conducted in the process of making the oil. Macadamia nut oil though is expensive: but as a treat it tastes so buttery. Nut oils don't contain much trypsin inhibitor at all or phytic acid I believe. Safflower has a very aggressive lectin and I would avoid it.

Salmon (wild-caught) and olive oil make me extremely nauseous as well! Especially if I eat those things in the morning. I still haven't found an answer as to why this is. :(

How are you with Soy? The farmed fish are usually fed a lot of that.

Re. the Olive oil, what kind of Olive Oil? Virgin/Extra Virgin/Pure/Refined? How sure are you of the source? One of the big problems with Extra Virgin Olive Oil in particular is fraud. Some people will mixes of oils or sell other cheaper oils as Extra Virgin Olive oil. You might think you're having a problem with the olive oil, and it's really a problem with some other oil.

Yah, flaxseed oil makes me sick as well. Tried it more than once and switched after getting sick from fish oil. What's odd is that I generally do well with eating oils(i.e. butter, refined olive oil, coconut oil, general vegetable oil).

OLIVE OIL SUCKS! It is way too heavy and it's frankly just another fad devised by the olive oil makers. My stomach prefers lighter oils such safflower or grape seed. Listen to your stomach. It knows what is best for you. Forget the commercials.

When I go to the grocery store, I cannot believe how this oil has taken over!
