Fish Oil Supplement: Benefits, Sources, Deficiency

Fish oil has been in use for centuries all over the world as a medicinal substance for various medical ailments. In the 16th century England, fishing communities used fish oil for treating various health issues like the common cold, skin diseases, body-aches and even wounds.

Then, circa 1970, there was a study of Greenland Eskimos conducted by a number of Danish experts, who reported that the Eskimos, in spite of their high-calorie diet, rarely suffered from cardiovascular diseases.

Later, it was determined that in fact, the high-fat fish diet they had consumed was actually the reason for their healthy hearts.

Further experimentation and observation led to the conclusion that their diet consisted of a specific type of unsaturated fatty acid called omega-3

As a result of continuing in-depth study of fish oil properties and the development of improved processing techniques in the following decade, by the 1980s the use of fish oil was convenient and widespread throughout the entire world.

Today, high-quality fish oils are ultra-refined and pharmaceutical-grade oils. They have neither a strong odour nor the unappealing taste of raw fish oil. In fact, they are also low in saturated fats and high in omega-3 fatty acids, thanks to the new and highly advanced refining techniques.

Both omega-3 and omega-6 are essential fatty acids found in abundance in fish oil, which is what makes it so special.

Benefits of Fish Oil

Several studies have proven that a healthy consumption of fish oil can cure several mental diseases such as depression or aggression, and even prevent the onset of schizophrenia.

Positive and beneficial effects of fish oil are found in cases of diseases like psoriasis. The effects of lupus, which is an ailment related to joints of the body and the skin, have been significantly reduced when fish oil was consumed in healthy quantities.

As previously mentioned, fish oil consumption is highly beneficial in improving the cardiovascular health of humans. Daily consumption of 1 gram of fish oil can have a considerable effect in reducing coronary diseases, as suggested by the American Heart Association.

Certain experiments conducted on fish oil have indicated a reduction in the blood pressure levels of patients. This happens due to the fact that fish oil does not get stored in the body, owing to its dissolving properties. 

However, fish oil supplements should be taken only under the proper supervision of a qualified

medical practitioner. Pregnant and nursing women should avoid a high intake of fish oil owing to the possibility of mercury contaminants present in them. 

Some reports suggest that fish oil has the potential to treat most types of cancers, particularly breast and colon cancers. Hence, you can use fish oil when preparing your food, as a preventive measure.

Apart from this, regular consumption of fish oil under the supervision of qualified medical help can reap multiple benefits for your body by improving its immunity, bone, health, skin, hair, and brainpower— and can thus delay the ageing process.

After rigorous research, it was confirmed that fish oil plays a vital role in the burning of the fatty acids that control the thyroid content.

Sources of Fish Oil

Fish oil contains two important omega-3 fatty acids, called EPA and DHA. Cold-water oily fish like sardines, salmon, and herring are found to be rich in these acids. 

Some common non-fish foods that contain omega-3 acids are flaxseeds, walnuts, hemp seeds, butter, soybeans, eggs and turkey.

Fish oil supplements are also readily available in supermarkets and drugstores and can be found in tablets, capsules or liquid form.

Deficiencies of Fish Oil

The first sign of omega-3 deficiency can be seen on the skin. Dryness, rough patches on the skin, dry hair and dandruff, and brittle nails may be the symptoms of lack of omega-3 in your body.

Although these are obvious symptoms, they are often overlooked. Some other symptoms are lack of concentration, aggression, poor sleep, fatigue and low tolerance.

Also, it should be noted that these symptoms vary with age. Regardless of the intensity of any one of these signs, it could be dangerous, as it may develop into a serious illness later.
