Fish Oil Grades

Fish oil production does not just provide one type of end product. In fact, there are also other grades of fish oil being produced. The three types of fish oil produced today depend on their level of quality.

Cod Liver Oil
Cod liver oil, despite its popularity as a nutritional supplement, is considered as a low quality grade of fish oil. It may only be used in small amounts as an ideal supplement since this form of fish oil may contain certain contaminants. Cod liver oil is also known to contain high levels of vitamin A which can be toxic to humans in large doses.

One teaspoon of cod liver oil contains 500 mg of long chain omega 3 fatty acids. Cod liver oil contains the highest levels of contaminants which may include DDT, PCBs as well as organic mercury. Taking this type of fish oil may not be safe in large quantities.

Health Food Fish Oil
Better quality grade fish oil is one that is sourced from a particular species of fish such as salmon. Most of these health food grade fish oil are usually available in soft gel capsules because they still carry with them a very poor taste profile. There is also a cholesterol free version of this type of fish oil grade.

This type of health food grade fish oil undergoes a slightly more purification process by means of limited molecular distillation in order to remove some of its cholesterol content in order to label it as cholesterol free. An even purified version of this health food grade version of fish oil is known as fish oil concentrate. This is the type of fish oil consisting of ethyl esters of the fish oil that undergoes fractional cooling. This allows a more purified form of fish oil with lesser amounts of contaminants that cod liver oil.

Generally, this type of fish oil contains a better concentration of omega 3 fatty acids. A single one gram capsule contains about 300 mg of omega 3 fatty acids. One capsule of a thermally fractionated health food grade can contain as much as 500 mg of long chain omega 3 fatty acids.

Pharmaceutical Grade Fish Oil
Pharmaceutical grade fish oils have been ultra refined in order to provide the highest quality of fish oil. This grade of fish oil undergoes through certain specialized processes in order to come up with the most refined fish oil. Certain specialized equipment is usually used in order to detect the minutest amount of contaminants in the fish oil. Because it is ultra refined, it is thousand times purer than the molecular distilled health food grade fish oils.

An ultra refined pharmaceutical grade fish oil contains more omega 3 fatty acids than the previous two fish oil grades. A one gram of this type of fish oil contains around 600 mg of long chain omega 3 fatty acids. And for being the most refined of the three grades of fish oil, it contains the smallest amount of contaminants.

Fish Oil For The Heart

It seems that a lot of research and studies are showing how effective fish oil is in helping improve our heart conditions. Studies in Denmark showed that fish oil could reduce heart attacks by 50 %. While the Journal of American Medical Association published a report from Harvard School of Public Health that states that women who consume fish with higher Omega-3 fatty acid lessens their risk of incurring any heart disease.

These evidences show us how good Omega-3 fatty acid is to our body. This would actually improve our life and lengthen our life span. High contents of Omega-3 fatty acids can be found in fish like salmon, mackerel, sardines, herring and anchovies. They have docosahexaenoic acid or DHA and eicosapentaenoic acid or EPA which have anti-inflammatory and anti-coagulant effects.

Omega-3 fatty acid belongs to the polyunsaturated fats, along with omega-6 fatty acid. Omega- 6 acid come mainly from vegetable oil. Omega-6 oils can also provide the body with heart and health benefits, but too much is also bad for the body. Omega-3 fatty acids do not only help in heart issues, but also support brain development.

EPA and DHA are very important to our body. But the body does not produce Omega-3 fatty acid. We have to get the nutrients from our food. Omega-3 acids are called or referred to as building blocks of the body. They help the brain and vision development, not only for children but for adults as well.

Italian researchers actually say that consuming about 1 gram of Omega-3 per day would show significant effects on reducing heart attacks. A gram of Omega-3 fatty acid can be present in a medium sized serving of salmon.

How do these acids exactly reduce heart attack risks?

They reduce triglyceride levels. Triglycerides come from fats of the food that we eat and calories not digested. In excessive amount, tryglycerides can cause coronary heart disease. They are just like cholesterol, they block the arteries and these can lead to heart attacks.

Aside from that they can also stabilise irregular heart beat. It can lower blood pressure and increase the level of good cholesterol. They also have anti-inflammatory characteristics. They are also anti-coagulant which means they make sure that they platelets do not stick together are clot. These clotted platelets can also block the arteries and the blood flow. You call this Thrombosis.

But according to a research led by Dr. Jochen Senges of the University of Heidelberg, the risk for a second attack among patients who used recommended medications compared with those who are using fish oil has no significant difference. It just show how important it is to avoid getting any heart attack in the first place.

You can take fish oil supplement or eat a lot of fatty fish but if you do not combine them with a healthy heart diet, still it is going to be useless. A healthy heart diet would include high fiber food like vegetables, fruits, whole grains, beans and nuts. Aside from eating fish, eating good quality protein products like lean poultry, non-fat dairy, and other products that does not contain saturated fat or trans fat.

Fish oil is not a magic pill which can transform you immediately into a healthy person just by taking them. Being a healthy person does not only require taking food supplements but also eating properly and healthily.
