It all started with the Greenlandic Eskimos. In the 70s of the last century, environmentalists had already gained sufficient influence and began to pry into their affairs.
They quickly found out that Eskimos eat tons of seafood and rarely suffer from coronary heart disease. It turned out to be all about the omega-3 fatty acids from fish oil.
It is clear that the rest of the world also wanted to support their hearts with useful acids.
Ordinary people would not like pickled seals, so they settled on fish oil in capsules.
Since this is a food product, it was solemnly declared useful for the health of our heart, but with the amendment that no hard scientific justification has yet been obtained.
This story reminds me of fruits and vegetables, which definitely increase the immunity of people, but still have not received a scientific basis.
In the case of fish oil, there are several proven health effects.
Triglycerides
Omega-3 fatty acids from fish reduce triglyceride levels in our blood. Not cholesterol, but literally fat. This is useful.
Blood pressure
Fish oil lowers blood pressure slightly. And everyone. It reduces it most strongly to those who already have untreated arterial hypertension.
This is believed to be due to nitric oxide, which dilates the peripheral vessels.
Pulse
The fatty acids from fish oil slightly lower your heart rate. Something about one and a half beats per minute.
This case was studied, and it turned out that fatty acids literally act on the electrical activity of the cells of the heart muscle.
Personally, this fact bothers me a little. I don't like the idea that fish oil will saturate my heart and make it beat less than usual (I already have a heart rate of 50).
Heart work
In principle, fish oil is good for the heart.
Blood clotting
In the usual amount of up to 4 grams per day, omega-3 fatty acids from fish oil do not affect the blood in any way. In large quantities, all sorts of oddities appear, such as lengthening the bleeding time, but no serious harm from this was noticed.
Suction
Fish oil travels in our blood as triglycerides, travels to the liver and is sent for processing. After a few days, it is embedded in the membranes of various cells and completely dissolves in our body.
It is believed that omega-3 fatty acids not only integrate into cell membranes, but also make them work differently. And they can also run inside cells and even somehow influence the activity of some genes.
After you stop taking fish oil, these fatty acids disappear from the blood in a few days, but they can remain in the cell membranes for a couple of months.
It is difficult to get poisoned with fish oil, but it is better to consult your doctor.
