Why Having Fish Oil in One’s Diet is Important

Why do we need fish oil in our diet? Why is it important? The short version of the answer to those questions would be: we’re not healthy if we don’t. Allow me to read some of your thoughts. You are probably thinking at the back of your mind that fish oil are just fatty oils and you know you have been told for so long that fats are not good for one’s health so what is this writer raving about? Totally excluding fish oil in one’s diet is not a healthy practice, is that true? And now kindly prepare yourself for the longer version of the answer to those two questions will follow next.

But before we go into the fish oil benefits let’s briefly explain the omega-6 and omega-3 essential fatty acids. These are the two main divisions of the fatty acids. Vegetables oils like soy oil and corn oil fall under the omega-6 group. And most of us are aware, and take note that experts agree on this, that too much intake of vegetable oils could result to blood clothing and inflammation.

This is probably one of the reasons why you are reluctant to believe that not all fatty oils are bad for your health. In fish, the omega-3 fatty acids are produced by marine planktons which are part of the fish’s diet. The omega-3 contains eicosapentaenoic (EPA) and docosahexaenoic acids (DHA) which are basically the two important fatty acids that gives the body the most number of benefits.

Among the health benefits of EPA and DHA include preventing heart attacks, the development of cancer and atherosclerosis. In fact, studies have shown that people who eat more fish have lower chances of having their blood vessels inflamed which is definitely good for the heart. By eating a fish diet or taking fish oil supplements, the heart becomes healthier. Moreover, other studies have confirmed that by including fish in one’s daily meals could help combat hypertension and obesity. These acids are also known to lower blood pressure.

Some studies have found out that fish oil when used by people with asthma conditions seems to provide relief and a general improvement of health conditions. Aside from those with asthma and other allergies, people who are being treated for depression and mood swings can use fish oil as well to help them control their emotions.

Although, we still maintain that the best way to obtain fish oil is by eating the fish such as salmon, tuna and mackerel. However, due to several reports that the fish we eat contained rather high levels of the mercury, a pretty dangerous element. Pregnant women and those with young children should avoid eating fish with high mercury levels.

While having fish oil in one’s diet is indeed very important, nowadays it is becoming more of a risk to get your daily allotments of fish oil from the eating salmon, tuna, mackerel, etc. Even though they are still the best ways to get your essential fatty acids, due to some recent reports of high levels of mercury found in fishes, it might actually be better to go with fish oil supplements instead.

These supplement capsules can be bought from health and even drugstores. But make sure you pick the best brand of supplement and read reviews as well as get referrals from friends. Don’t think for a minute that you’re just being picky.

What you’re doing is making sure that you will invest your money on a trusted supplement brand.

Understanding Fish Oil

Fish oil has a long history of being used as a nutritional supplement. It is generally derived from oil coming from the tissues of oily fish. There are many sources of fish that the world gets its fish oil supply from. But about 50 percent of all fish oil production in the world comes from farmed salmon.

Fish Oil Sources
Fish oil is primarily derived from farmed salmon. There are times when fish oil may also be sourced from other fatty fish notably mackerel, lake trout, flounder and tuna. But such types of fish are known to be predatory. And because of this, they run the risk of accumulating certain toxic substances such as mercury, dioxin and PCB’s. In order to avoid this and have fish oil sources known to be as clean as possible, farmed salmon are the best option.

Fish Oil Benefits
One of the things why fish oil has become quite a popular nutritional supplement around the world is because it is very rich in Omega -3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid. These compounds are said to help reduce the risk of coronary heart disease. There are also studies that say that these nutrients also have anti-cancer properties as well as may help in certain cases of depression.

Fish Oil Production
Production of fish oil is shared among a number of countries. But it has been seen that there was a substantial decrease in total fish oil supply, mainly because of declines suffered by a lot of the said countries. Countries such as Peru, Chile, Denmark, Iceland and Norway are known as the five major fish oil exporting nations.

Adverse Effects
Despite the various benefits that fish oil is said to offer as a supplement, medical experts still suggest caution in overusing it. There have been studies that indicate certain risks associated with fish oil. In some studies, there are suspected risks that researchers have found in the use of EPA and DHA fatty acids in fish oil.

Over usage of EPA and DHA, which is determined at more than three grams daily, are known to increase the risk of bleeding, especially in people who are also taking aspirin or warfarin. But further research may be needed to determine if EPA and DHA do offer such risks. Extreme dosage intake of fish oil is also associated with a higher risk of experiencing hemorrhagic stroke. In some individuals, fish oil intake may also affect LDL cholesterol levels.

Cardiac Risk
Because fish oil is still considered as fat, people with conditions arising from too much fat in their systems should also be cautious of taking fish oil as a supplement. Recent research seems to provide different results when it comes to how the fatty acids in fish oil affect people who may be suffering from heart disease or stroke.

In absence of definitive research, patients are being cautioned not to take fish oil without the recommendation from their doctor. People with certain heart problems or a history of heart disease should first talk with their doctors about the safety of taking fish oil supplements.

Choosing Fish Oil Supplements

Choosing the right fish oil supplement may not always be easy. One of the things to consider is that one should know about what makes such supplements valuable to health, which is its omega 3 fatty acid content. There are various sources of such essential fatty acids. It can be easy to question if there is indeed a difference between getting this nutrient from different sources.

Three Types Of Omega 3 Fatty Acids
One of the things that people should know is that there are three known types of omega 3 fatty acids, the essential nutrient found in fish oil supplements. The three types of omega 3 fatty acids include EPA, DHA and ALA. ALA, or alpha-linolenic acid is a short chain omega 3 fatty acid that is usually found in plant sources such as flax seed, walnuts, canola and soybean oil. DHA or docosahexaenoic acid and EHA or eicosapentaenoic acid are considered as long chain omega 3 fatty acids. The latter two are those found in fish oil supplements.

The difference between short chain omega 3 fatty acids such as ALA and long chain omega 3 fatty acids has to do with how the body processes them. In order for the body to make use of such essential fatty acids, it has first to convert the short chain types into its long chain form. This does not usually happen readily. That is why fish oil supplements are considered more effective in providing the omega 3 fatty acids that it needs because it is already the long chain form which does not require any more conversion before the body can use them.

Effectiveness
One of the other things to consider when choosing between fish oil supplements and ones that are sourced from plants deals with their effectiveness and benefits. Experts believe that the long chain omega 3 fatty acids being sourced from fish oils prove to be more effective in terms of health benefits. These essential fatty acids have already been known to offer some benefit in preventing heart disease. With the short chain fatty acid ALA however, experts are not too sure if ever it does provide the same benefit because it may still require additional conversion before it can be used by the body.

Fish Oil Source
Now that one already knows the difference between omega 3 fatty acids sourced from fish as well as those from plants, it seems that fish oil seem to have the upper hand. But this time there are some other things to consider. In order to get the type of fish oil supplements that offer the best source of long chain omega 3 fatty acids, people should know where they are being sourced from.

One important thing for consumers to look at when buying fish oil supplements is the label. It should contain information of where the fish oil used in the supplement is being sourced from. Because there can be more than just one fish species to source out such supplements, it is important to clearly know what types of fishes these may be.

Certain labels may contain information of the fish oil being sourced from salmon, tuna or anchovies. This might be considered safe. But if labels on the said supplements only tell of fish oil or marine lipids, this should ring some warning bells. It may be possible that fish oils in such supplements may not be too sure where the source may come from, which might also cast some doubt on the purity of the fish oil being used

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, PCB’s 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 Side Effects – Benefits

Fatty fish like salmon, tuna and mackerel have fats that can produce fish oil. Fish oil contains Omega-3 fatty acids which are recommended by health-care professionals to be included in a individual’s diet. Omega-3 acids are mainly docosahexaenoic acid or DHA and eicosapentaenoic acid or EPA.

Omega- fatty acids are essential in cell building. It is important to get them from our diet since the body cannot produce this kind of acid. Research showed that Omega- 3 plays a significant role in brain and fetal development during pregnancy and infancy. Fish oil are believed and proven to provide numerous health benefits. Aside from this, there are also a lot of advantages by taking fish oil supplements.

Fish oil can:

• Improve brain development and memory. There are studies showing that DHA actually plays a major role in brain functions. Low levels of DHA can increase the risk of having Alzheimer’s disease. Intake f fish oil during pregnancy is also recommended. According to a research conducted by the University of Western Australia showed that pregnant women who ingest fish oil supplement actually give birth to babies with better hand and eye coordination, better in speech and better cognitive development at the age of two and a half.

Aside from Alzheimer’s disease, fish oil can also help in reducing the risk of other mental illnesses like depression, Attention Deficit Hyperactivity Disorder (ADHD) among children, dyspraxia, bipolar disorder and dyslexia.

• Reduce the risk of heart attack. Even if the DHA and EPA are fatty acids, they can reduce cholesterol, triglycerides and blood pressure. It helps in preventing blood clots in the heart. So aside from heart attacks, fish oil is also important in reducing risks of coronary heart disease.

• Reduce the risk of cancer. Researches have showed that fish oil can help in reducing risks of developing breast, prostate and colon cancer. They stop the growth of cancerous cells and inhibit its growth. For postmenopausal women, those who consume more Omega-3 fatty acids from salmon and mackerel or fish oil supplements are less likely to develop breast cancer.

• Reduce the effects or helping patients deal with lupus, arthritis, colitis and asthma. Its natural anti-inflammatory capabilities can reduce pain brought by inflammatory arthritis and gastritis.

• Help a lot during pregnancy. Not only does Omega-3 fatty acids and fish oil help in he fetal brain development, it can also reduce the risk of giving early or premature birth, post-partum depression for mothers, allergic reactions among babies an low- birth weight. Not only does it helps in pregnancy, there are preliminary researches showing fish oil to aid in getting pregnant or fertility.

• Help improve the body overall. Fish oil can help in producing serotonin, the happy hormones. Happiness can help a lot of people deal with stress and other emotional issues which can totally improve a person’s emotional and mental disposition. They can also revitalize and rejuvenate skin, reduce wrinkles, weight loss and improve eyesight. It is even said that fish oil can reduce acne and make your hair a lot better.

Fish oil is very important in building a better you. But doctors and experts suggest in taking pharmaceutical grade fish oil supplements. The problem with eating too much fish can actually lead to mercury contamination.

So, ask yourself, are you getting enough fish oil in your body? If not, then it is time to start making sure that you do.
