Dear readers, you are not the first to take care of this. The question is serious. Specially trained people tested different versions of canned Baltic cod liver and calculated that in that oil, which floats in the jar, there will be about 30% of the beneficial unsaturated omega-3 fatty acids, and in the pieces of the liver themselves - somewhere 15%. Researchers believe that 5 grams a day of these pieces would be enough for us to meet the need for omega-3. But our people are not looking for simple ways and demand to count how many cans per day they could eat without harm to health.
Here we should return to theoretical foundations of fish oil absorption. In biologically active food supplements, these same omega-3 unsaturated fatty acids are usually not eaten more than 4 grams per day. Anything larger can already unbalance something in our body.
It turns out that you can strain somewhere a tablespoon of fat from a jar of canned cod liver or eat out 30-40 grams of the pieces themselves. And this will be the maximum daily intake of fish oil that can be absorbed every day.
The problem may be that different canned foods will differ. This is a food product, not a medicine. So the manufacturer has a free hand.
It is said that such fat, including the beneficial omega-3 fatty acids, is more or less decently stored and does not go rancid in the first six months.
Mercury and any other filth in such canned food is traditionally present, but in the recommended amount, this mercury will not be poisoned. So you don't have to bother.
In short, cans of cod liver will not work. First, he will vomit. And, secondly, you can get used to omega-3 along with mercury. Therefore, it is useful to make a couple of buters, but no more.
I advise you to read my article from the link in the text above about fish oil from the point of view of modern medicine, and also these two articles:
