According to recent research by scientists from Harvard University, Omega-3 fatty acid deficiency is one of the ten leading causes of adult mortality on the planet. The main source of Omega-3 is fish oil.
General characteristics
Fish oil is a form of fatty acids derived from fatty fish tissues. The most common sources are: mackerel, herring, trout, sea bass, halibut, sardines, swordfish, tuna, salmon, anchovies. Oysters are also used. The quality of the product largely depends on the type of raw material. Oily fish fillets contain up to 30% oil, and this figure may vary. So, in the carcasses of white fish, the main lipid reserves are concentrated in the liver, and their fillets are leaner.
People whose diet is deficient in seafood can replenish their omega-substance by taking active dietary supplements.
Types of fish oil
Today, fish oil is available in 3 forms.
1. Natural. It is a highly bioavailable product. The disadvantage of the form is, as a rule, a low level of eicosapentaenoic and docosahexaenoic acids. In addition, most often hazardous substances are found in this form of fish oil.
2. Ethyl ether. It is a natural oil that has been distilled to remove impurities. The presence of eicosapentaenoic and docosahexaenoic acids in this form of fish oil is increased by 2-3 times.
3. Synthetic oil. It is characterized by a change in the molecular formula, which affects the bioavailability of the product for the worse.
Studies have shown that the body perceives natural fish oil best of all (approximately 2-3 times better than the synthetic form).
Nutritional value
All types of fish oil store a certain amount of polyunsaturated fatty acids. Nevertheless, fat obtained from cod liver or shark contains significantly more vitamins A and D. Fermented cod liver oil is even more beneficial, since it already contains vitamin K2, a deficiency of which is felt by the majority of the world’s population. By the way, it is this vitamin that is responsible for the proper coagulation of blood, the health of the heart, blood vessels, skin, bones, and also supports the body’s ability to grow and prevents the formation of malignant tumors.

Benefits of fish oil
Fats derived from fish are useful for treating heart disease, depression, inflammatory bowel disease, arthritis, Alzheimer’s disease, eczema, diabetes, cancer, autoimmune diseases. Actively used to lower cholesterol levels. It has been proven to help with weight loss, improve skin condition, promote a healthy pregnancy and enhance fertility.
The main benefit of fish oil is determined by the presence of omega-3 fatty acids in it, in particular eicosapentaenoic and docosahexaenoic acids. The product also contains other useful essential fatty acids – alpha-linolenic and gamma-linolenic.
Lack of fish oil: the dangers and consequences
Insufficient amount of fish oil in the diet can cause many diseases. An imbalance between omega-3 and omega-6 fats can also cause health problems. Ideally, their ratio should be 1:3. However, according to the researchers, in practice this figure is far from the recommended one. Imbalance occurs due to malnutrition. The easiest way to restore the necessary proportion is to give up fast food and introduce foods rich in fish oil into the diet.
An organism that lacks the nutrients contained in fish oil, as a rule, suffers:
- autoimmune diseases;
- cardio diseases;
- cancer;
- 2 type diabetes;
- obesity;
- asthma;
- intestinal dysfunctions;
- metabolic disorders;
- dystrophy.
Benefits for the body
Fish oil belongs to those products that are indispensable for a person throughout life, because they affect the performance of many systems.
Heart Health
Many clinical trials have shown that Omega-3 is one of the most effective substances for reducing the incidence of cardiac diseases. Therefore, fish oil is beneficial for people with diseases of the cardiovascular system.
In addition, it has been proven that this product reduces the level of bad and increases the indicators of good types of cholesterol in the blood, prevents the accumulation of triglycerides. There is also speculation that fish oil may be useful in preventing the progression of atherosclerosis in individuals with coronary heart disease and after a stroke, and regular consumption reduces the risk of sudden death from cardiovascular events.
Weight loss
Perhaps this is the second most publicized ability of fish oil. Scientists and volunteers from Australia checked whether it is true that this useful product promotes weight loss. It turned out that fish oil improves the effect of exercise on weight loss. And the French have calculated the most suitable dosage for weight loss. According to them, 1,8 g of fish oil and moderate exercise will allow you to get rid of extra pounds in just 2 months.
Protection against cancer
It has been found that this product is able to destroy the cells of various types of cancer, including the colon, prostate, and breast. It has also been proven that seafood fat is an effective tool for the prevention of cancer.
Strengthening immunity
Today, science is aware of the existence of many immunomodulators, and one of them is fish fat. Regular consumption of the product helps the body resist colds and viral diseases. Omega-3, present in fish oils, strengthens the immune system by stimulating the cytokines and eicosanoids found in the human body.
Also, fish oil is considered an effective remedy for people suffering from lupus. In individuals with this autoimmune disease, the immune system attacks healthy organs and tissues in the body. But the systematic use of fish oil reduces the fever, skin rash and weakness that are characteristic of this disease.
AIDS treatment
There is an opinion that fish oil is an indispensable component for the treatment of AIDS. But so far, this theory requires more research, since many scientists are not sure about the effectiveness of such treatment.
Anti-inflammatory properties
This special type of fat is effective in the treatment of inflammatory processes in different types of tissues. Many doctors attribute fish oil to their patients with chronic inflammation. This drug is believed to be important in the treatment of intestinal disorders, celiac disease, Crohn’s disease, ulcerative colitis. In people with bowel disease, the ability to absorb vitamins, fats, and other nutrients is impaired. Seafood fat is a healthy food supplement for them. For those with ulcerative colitis, this product is important as a means of preventing the accumulation of leukotrienes in the colon.
arthritis treatment
Fish oil is beneficial in the treatment of arthritis, rheumatism. In this, at least, scientists from Australia are sure. They determined that the product weakens the action of substances that destroy cartilage. However, what should be the optimal dosage in order to completely stop the development of the disease is still unknown. In addition, the benefits of fish oil in the prevention of osteoporosis have been established.
Remedy for depression and anxiety
For people prone to depression, it is important to include oily fish in the diet. It relieves anxiety, restlessness, mental fatigue, stress, depression and other nervous disorders. In addition, fish oil may be an effective treatment for suicidality and bipolar disorder. By the way, the analysis showed that in countries where seafood is the main food, the frequency of violence and the level of murders is significantly lower than in countries with a shortage of fish.
Eye health
It is known that fatty seafood has the ability to improve vision, and also helps to avoid age-related macular degeneration. For this reason, ophthalmologists advise their patients to eat foods rich in Omega-3 fat as often as possible.
Alzheimer’s Prevention
For several years, researchers have studied how fish oil affects the cognitive functions of the brain. It turned out that the substances contained in fish fat can prevent the atrophy of brain cells and reduce the risk of Alzheimer’s disease. Also, foods rich in omega-3 fats work as a defense against dementia.
Effect on the central nervous system
If children have symptoms of hyperactivity and inability to concentrate, emotional instability, poor memory, poor coordination of movements or impulsivity are characteristic, all this serves as a basis for increasing portions of fish oil in their diet. In addition, it is believed that people who regularly consume this product have a higher IQ level, they learn more easily, they are characterized by emotional stability and good memory.
By the way, it was experimentally found that the consumption of fish oil as a dietary supplement for 15 weeks improves the condition of hyperactive children, and also increases the efficiency of the brain (because its tissues are almost 60% composed of fat), and the ability to learn is improved.
Benefits for pregnant women
Well, and, perhaps, pregnant women need fish oil most of all, because in this case we are talking about the health of two people – the expectant mother and child. There is reason to believe that the lack of a product in the diet of pregnant women causes premature birth, increases the risk of miscarriages, as well as improper formation of the brain and eyes of the child. In addition, mothers whose diet lacks oily fish are more likely to suffer from postpartum depression.
Man’s health
But not only the female body needs fish oil. Men’s health is also directly dependent on the consumption of this product. Researchers believe that fish oil can improve sperm quality, increase survival and mobility of sperm.
Skin Benefits
Dry skin, a tendency to eczema, psoriasis, frequent itching, rashes, redness and irritation – many face these dermatological problems. Fish oil reduces the loss of moisture from the epidermis and the incidence of inflammation. Topical application of this product helps to relieve the symptoms of psoriasis. There is also evidence that fish oil protects against sunburn, treats acne. And according to recent studies, it prevents skin cancer.
On the other hand, it is important to remember that this fat is the source of many components that are useful for maintaining the youth of the skin. It prevents the appearance of early wrinkles and age spots, moisturizes the epidermis.
Hair Health
Omega-3 nourishes the follicles and stimulates the growth of healthy hair. Fats from sea fish serve as a good prevention of baldness. It is also worth remembering that fish is an excellent source of proteins, which are essential for maintaining healthy hair.
Influence on other organs and systems
In addition, fish oil is useful for:
- maintain the integrity of cell membranes;
- prevention of amyotrophic lateral sclerosis;
- improvement of blood circulation;
- prevent renal failure;
- lowering blood pressure;
- maintaining health with diabetes;
- treatment and prevention of ophthalmologic diseases;
- treatment of epilepsy, schizophrenia.
Fish oil or vegetable oil: what to choose
There are plenty of advocates around the world to ditch fish oils in favor of vegetable oils, which some say contain even more omega-3 fatty acids than seafood. However, this advice is far from helpful.
The fact is that Omega-3 is a complex name for 3 substances:
- linolenic acid;
- eicosapentaenoic acid;
- docosahexaenoic acid.
All these substances are important for the body. However, vegetable oils contain only the linolenic substance, and the other two acids must be obtained from seafood to maintain balance. In fairness, it should be noted that the body has the ability to convert linolenic acid into eicosapentaenoic and docosahexaenoic acid, but this is not enough for human needs.
Dosages and Precautions
Fish oil, as you already know, is a useful component of the diet. However, excessive passion for them can cause adverse consequences.
Symptoms of overdose:
- fever and chills;
- increased heart rate;
- skin rash;
- stomach upset;
- unpleasant taste and dry mouth;
- belching;
- damage to the liver and kidneys.
The optimal daily allowance for healthy adults is considered to be 1000 mg of the substance. Before taking it as a dietary supplement, it is important to consult your doctor.
Although concentrated dietary supplements are far from the only way to replenish fatty acids in the body. It is much more useful to include fish, preferably sea fish, in your traditional menu. However, even here it will not be without dangers – some varieties of marine inhabitants may contain mercury, which they have absorbed from the water. Therefore, it is so important to know where the fish that hit your table was caught.
How to choose fish oil
When choosing a fish oil, it is important to consider several factors: the purity of the product, its freshness, nutrient content. You also need to understand that not all fish fats are equally useful. And if the raw material was caught in polluted waters, the product may even be dangerous to humans.
In addition, the effectiveness depends not only on the amount of polyunsaturated fats, but also on their molecular structure. Natural fish oil is easier to digest than the pharmaceutical counterpart.
Eating fish oil brings with it a number of benefits. This substance will protect against serious diseases, improve brain function, help lose weight and build muscle. It seems that in the human body there is not a single system or organ that does not feel the beneficial effects of this product.
