Recent studies have suggested that human brain is composed of lot of oils. The main source of these oils is found to be only fish. Hence it can be stressed that fish oil is very essential for human health and development. It is believed that our ancestors lived in coastal areas, which helped them to get much of their nutrition from fish, especially shellfish.

Fish oil has been established as the source of many health advantages. It has been proven to help control blood serum cholesterol. It can help treat high blood pressure, and assist in the prevention of heart disease. It has also been used to treat neurological conditions, such as depression and memory loss.

Probably the most vital components of fish oil are omega 3 fatty acids. The human body is not able to make omega 3. Omega 3 are generally not found in plants and when they are found in plants it is in very small amounts. The development of an unborn child's brain and eyes are dependent upon the availability of omega 3; for this reason it is vital that expecting mothers get enough omega 3.

As more studies have slowly begun to take place, a strong link has been developed between a lack of omega 3 and a variety of health problems. Among the diseases now begining to be associated with a lack of omega 3 are asthma and the now ever more occuring diagnosis of Attention Deficit Disorder. A correlation has also been noted relating an omega 3 deficiency during pregnancy to poor hand-eye coordination, poor social skills and decreased IQ in children.

Salmon, sardines and herring are the fish which contain large amounts of omega 3. But at the same time, eating large quantities of fish is quite unsafe as dangerous heavy metals from water pollution may accumulate to dangerous levels in the body of a fish. Moreover, a fish liver may contain very high amount of rentinol which is an active form of Vitamin A and which can be very dangerous.

For this reason it is recommended that people take fish oil supplements. They are available in capsule form those who take exception to the taste. They should be certified free of mercury and other dangerous metals and many have been purified so that the body can assimilate them more easily. Omega 3 benefits human health in so many ways that it is frightening to learn that only 2% of the US population is getting the recommend daily amount.
