Fish oil was produced for the first time in England in 1775 extracting it from cod liver.
In the 80s, thanks to the technology, the fish oil wasn’t extracted from the liver any more, but from the body of the animal. It solved the problem of the toxicity of vitamin A mainly present in the liver. The mode of fish oil exploded in the United States in the mid-80s. It was soon abandoned because the amount of capsules was exaggerated with conseguent high costs . The characteristic of American food (high level if carbohydrates) loaded to to an increased levels of insulin. These are exactly the opposite of the benefit of the fish oil. The technology removed the vitamin A and some of the saturated fats, but the production cost remained too high. The decisive innovation was the removal of most of the saturated fats (via fractional distillation). The result was a new kind of fish oil that provided a large amount of omega 3 fatty acids. Nowadays the result is a concentrated fish oil, distilled several times. It is a cod liver oil, high-tech, efficient without the dangers of pollutants, has a pleasant taste and no side effects on the gastrointestinal tract.
What is fish oil?
Fish oil is a product that comes from residues of certain fish. It is used as food supplement thanks to its rich amount of omega 3 fatty acids (essential for the proper functioning of the organism).
Where do we get it?
The ingredients of fish oil are typically fish such as cod, trout, salmon and sardines. After the cleaning process the wasted parts such as heads, tails etc. are boiled. Through a chemical process and refining, we get the fish oil, a food source rich in omega 3.
The amount of omega 3 in fishes depends on the part of the body. In general, most of the content of fatty acids is accumulated in the intestine. The fish oil extracted from the liver of the animal, supply a quantity of omega 3 equal to the required daily dose.
Why is it important to eat omega-3s eating fish?
We all wonder why doctors, associations of well-being and our parents always use slogans like “eat fish that is rich in omega3.” The human organism is able alone to produce certain fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), known as omega 3. Although our body is full of such acids, it is unable, however, to turn them into useful substances to our needs. Also fishes are full of omega3 but don’t use them.
The beneficial properties:
Fish oil, in addition to being a rich source of omega 3, it has many beneficial properties:
– is ‘rich in iron.
– it has vitamin A, vitamin E and vitamin B.

Calories of fish are 902 Kcal (100g) , but the recommended daily dose is about 1.3 grams.
The nutritional properties :
The nutritional properties of fish oil, are provided by the fatty acids EPA and DHA. These acids provide a supply of energy is very important, without which the body could not function. Fish oil is rich in vitamin A and D, which play a key task for the proper functioning of the body. Lack of vitamin A can even cause vision problems. Lack of vitamin D can lead to imbalance in the secretion of parathyroid hormone that cause osteoporosis, muscle weakness and high blood pressure. A high content of vitamin E to fish oil gives a powerful antioxidant.
The therapeutic properties of omega 3:
The main therapeutic properties attributed to omega 3 concerns the preservation of cardiac function. They play an excellent action in the processes of vasodilation and vasoconstriction that regulate blood pressure.
The fish oil in case of diabetes:
Although not directly involved in the changes in blood glucose levels, fish oil can be very useful if taken regularly. The anti-inflammatory action of omega 3 reduces chronic inflammation typical of this disease state, which leads to a reinforcement insulin resistance.
The fish oil in children:
According to the latest research on omega 3, for a child who regularly consume fish oil, it is less likely to reach out to cardiovascular disease, stroke and heart attack.
Research has demonstrated the effectiveness of fish oil, taken in large amounts, in patients with conditions such as Parkinson’s disease, Alzheimer’s alzeihmer, dementia, multiple sclerosis and depression. The fish oil, in high doses, promotes the production of dopamine and serotonin.
Where can I buy fish oil?

Now we list some pretty serious side effects, the risk of bleeding: fish oil has the ability to break up blood clots and prevent the platelets clump. However, this only happens when people uses a large amount of fish oil. The Eskimos, for example, suffer because their diet is very high in natural fish oil.
Problems of contamination: despite the increased use of industrial filters, there is always the possibility that mercury, PCBs and other contaminants can be ingested by fish which in turn transmit them to us that we consume them.
