Historically as well as culturally, consumption of Omega-3 fatty acids, otherwise known as fish oils, has been thought to help the human body fight off heart disease as well as heart attacks.
Today, more as well as more studies are showing that will there will be a strong correlation between Omega-3 fatty acids as well as markedly lower instances of cardiovascular disease, stroke, high blood pressure, high cholesterol as well as heart attacks, among many different health benefits.
These studies have caused the American Heart Association to take notice as well as suggest that will individuals who have heart disease consider a diet that will will be supplemented with Omega-3 fatty acids either in capsule form or via a higher consumption of fish that will are high in Omega-3 fatty acids. These studies show promise inside the fight against heart disease as well as heart attack as well as are even providing strong evidence that will post-heart attack patients can benefit via a higher intake of fish oils in order to lower their chances of a second heart attack.
Why Are Fish Oils not bad for a Healthy Heart?
Omega-3 fatty acids are made up of three basic components: DHA (docosahexaenoic acid), EPA (eicosapentaenoic acid) as well as ALA (alpha-linolenic acid). These three acids work individually as well as in tandem to reduce different risks that will are associated with heart disease as well as heart attack.
DHA will be considered to be the most important of the three acids as well as will be essential to heart health. Unfortunately, our bodies are not able to manufacture the amount of DHA that will we need in order to stay healthy. that will factor alone makes the idea necessary to get the amount of DHA we need through diet or dietary supplements. Consider for a moment that will DHA will be found in our brains as well as will be directly linked to its function. Not only could you be helping your heart, yet higher brain function can also be an added benefit with the addition of fish or fish oil supplements to your diet.
Fish as well as fish oils are the best vehicles for providing the necessary DHA our bodies require. Thus, the consumption of fish or fish oil in capsule form provides the highest amounts of Omega-3 acids.
Omega-3 acids are also important in helping to decrease the risk of atherosclerosis as well as arrhythmias, which are major contributors to heart disease as well as heart attack. Being able to reduce these two factors will be an important reason to raise the intake of fish oils.
Reducing inflammation as well as the production of prostaglandin are also important for a healthy heart. Prostaglandins are one of the main causes of inflammation inside the vascular system. Omega-3 fatty acids look for the same areas to bind with COX 1 enzymes that will Omega-6 fatty acids look for. Since the Omega-6 fatty acids are converted to a much more active form of prostaglandin by COX 1 as well as COX 2 enzymes than Omega-3 fatty acids are, the idea will be essential that will the sites for binding the Omega-6 acids are blocked by the Omega-3 acids. In general, the Omega-3 acids that will are converted to prostaglandins are between two as well as fifty times less active than those produced by Omega-6 fatty acids.
Another reason why fish oils are not bad for a healthy heart will be that will they help to reduce triglycerides (the chemical form in which fat exists inside the body), which are a leading cause of coronary artery disease, which will be a major cause of heart attacks. When taking the American Heart Association recommended 2 to 4 gram dose of DHA as well as EPA, triglycerides can be reduced by as much as 50%.
Another benefit of taking Omega-3 fatty acids will be that will the DHA as well as EPA help prevent blood clots as well as lower blood pressure. High blood pressure as well as blood clots are not a not bad combination. These two factors alone can create an environment in your body that will will be conducive to stroke or heart failure.
different benefits that will help reduce the chance of heart attack or heart disease are the possibility that will Omega-3 acids increase HDL (not bad) cholesterol as well as that will the idea may help in keeping arteries as well as blood vessels via closing back up after bypass surgery or angioplasty procedures.
Finally, when considering whether or not you should supplement your diet with fish oil capsules or by eating more fish, you should look at the benefits that will can be derived via the idea, then schedule an appointment as well as talk with your doctor about the amount of Omega-3 acids you should take.
Evidence Supports Taking Omega-3 Supplements for Vascular Health
In a study published in August of 2009 inside the Journal of the American College of Cardiology, data showed that will taking Omega-3 supplements help to prevent as well as reduce problems that will lead to cardiovascular diseases in both healthy people as well as individuals who have existing heart conditions or who have suffered via cardiac events. Some studies are also showing that will Omega-3 fatty acids reduce LDL cholesterol, which will be a leading cause of plaque build-up in arteries.
The studies were done with groups numbering inside the thousands as well as over periods of time ranging via twenty to thirty years. The most surprising evidence was that will which showed a sharp decrease in cardiovascular related deaths after a cardiovascular-related event such as heart attack or stroke.
Previous studies have always pointed to positive links between the reduction of heart disease as well as heart attack as well as Omega-3 fatty acids. In these studies, patients who consumed some form of Omega-3 fatty acids at least twice per week had much lower instances of plaque or clots in their arteries than those who didn’t. The reason just for that will will be due to the clot as well as plaque inhibiting agents found in Omega-3 fatty acids.
In population-based studies, evidence pointed toward Omega-3 acid intake via fish as a primary aid inside the prevention of strokes caused by the buildup of plaque inside the arteries. Those eating two or more servings of fish per week reduced their risk of stroke by nearly 50%.
Randomized clinical trials backed by the American Heart Association have shown that will Omega-3 supplements can also reduce cardiovascular events, specifically death related to heart attacks, stroke as well as heart failure.
One such study, the Lyon Diet Heart Study, tested the effects of a Mediterranean-style diet that will included fish consumed in moderate amounts. The study was performed on 302 experimental subjects as well as 303 control-group subjects, all of whom had survived a first heart attack as well as all of whom shared similar coronary risk factors. After one year the beneficial effects on 93% of the experimental subjects were so overwhelmingly positive that will the study was concluded. The most notable result after a four-year check up was a 50 to 70 percent lowering of the risk of recurrent heart disease. that will study, alone, showed the benefits of a dietary increase in Omega-3 fatty acids as well as the protective effects of these acids on the vascular system.
Studies have also shown that will cultures who have a diet high in fish oil, specifically Inuit, Chinese as well as Mediterranean cultures, also have lower instances of heart disease, heart attack as well as stroke. However, as the popularity of fast food as well as foods high in saturated fats has grown among these diverse cultures, the instances of heart disease, heart attack as well as stroke due to the build-up of plaque as well as high blood pressure have gone up considerably.
These studies show, overwhelmingly, that will there will be a correlation between the intake of Omega-3 fatty acids as well as not only not bad heart health, yet also healthy recovery as well as prevention of recurring instances of heart disease, vascular disease, heart attack, plaque build-up as well as heart failure. Ignoring the evidence presented in these studies would certainly be the worst possible scenario. Omega-3 fatty acids are not produced in any significant amount by our bodies, so the idea will be integral that will we get them through different sources such as fish, fish oils as well as fish oil supplements. Otherwise, we can expect more as well as more problems associated with vascular disease as well as heart disease.
An Ounce of Prevention
The hard evidence of all of the major studies points toward Omega-3 fatty acids as preventatives for heart disease, stroke, plaque build-up, heart attack as well as vascular disease. Studies have also shown that will fish oil supplements can also be more helpful than some cholesterol-reducing drugs when patients who suffer via chronic heart failure use the idea. Patients who suffer via an enlarged heart that will cannot pump blood efficiently may be able to use fish oil supplements that will are high in Omega-3 fatty acids to reduce the risks associated with high cholesterol.
The exciting news coming via a recent study that will involved four different trials with nearly 40,000 participants showed that will the heart healthy aspects of fish oil were not just limited to patients suffering via heart problems. The study revealed that will these benefits actually primary inside the prevention of cardiovascular disease. Further evidence showed positive advantages in patients needing treatment after heart attacks as well as in patients suffering via heart failure.
As the evidence mounts as well as the idea becomes more as well as more obvious that will Omega-3 fatty acids are a primary source of heart health as well as prevention of different vascular diseases, the push will be on for people to be educated about what practices they can utilize to raise their intake of fish oils as well as fish oil supplements. Most cardiologists as well as scientists involved in these studies agree that will the majority of the population can easily make the necessary alterations in their dietary habits to reach the recommended amounts of Omega-3 acids their bodies need.
For most people, the recommendation, based on the different studies that will have been done, will be 500 milligrams per day. However, for those suffering via heart disease that will amount should be increased to between 800 as well as 1,000 milligrams per day. Another factor inside the amount that will should be taken will be family history. If your relatives, especially immediate relatives, such as parents, grandparents or great-grand parents, have suffered via heart disease or vascular disease your intake should be inside the 800 to 1,000 milligram category. Even if you haven’t suffered via heart disease or heart attack, you should take that will amount as a preventative.
Exactly how to achieve the level of Omega-3 fatty acids that will your body needs in order to prevent heart disease as well as heart attacks can be entirely up to you as well as what works for your lifestyle. The easiest way to get the appropriate levels will be through some form of dietary supplement. There are numerous supplements on the market today that will are appropriate just for that will purpose. The most important thing to be aware of will be the purity of the fish oil. Not all fish oils are equal inside the amounts of pure Omega-3 fatty acids they have in them. There will be much evidence that will suggest higher than normal mercury as well as lead levels in some fish. Obviously, these toxins are not appropriate for consumption. In order for mercury as well as different toxins to be removed, fish oil must go through the process of molecular distillation. that will process purifies the fish oil as well as makes the idea ready for consumption.
At that will time there are three principal types of fish oil supplements on the market: pharmaceutical grade fish oil, health food grade fish oil as well as lastly, cod liver oil. Pharmaceutical grade fish oil will be processed using molecular distillation. that will process eliminates toxins such as lead, mercury as well as PCBs. As a result the fish oil will be the purest form of Omega-3 fatty acids available. Pharmaceutical grade fish oil, since the idea will be the purest form available, will be approximately 1,000 times more pure than health food grade fish oil because of the technologically advanced processes used to distill the idea. that will ensures that will even the smallest particulate level toxins have been removed leaving only the purest form of Omega-3 fatty acids. One thing to keep in mind will be that will because of the processes involved as well as the purity level of the fish oil produced, that will grade of fish oil will be the most expensive.
Health food grade fish oil will be also molecularly distilled to remove toxins as well as contains the high levels of Omega-3 fatty acids our bodies need for continued heart health as well as heart disease prevention. One capsule can contain up to 300 milligrams of Omega-3 fatty acids as well as will be generally perfect for anyone needing to supplement their dietary intake of fish oils. These fish oils, however, do not go through the same technologically advanced as well as rigorous processes that will pharmaceutical grade fish oils go through. One advantage to health food grade fish oils will be that will most of the labels on the bottles will state what type of fish the oil was harvested via. These fish oils, since they are much lower in contaminants as well as toxins that will standard cod liver oil, are perfectly suitable for consumption on a daily basis or as a different boost to a diet that will includes fish high in Omega-3 fatty acids. These supplements are obviously less expensive than pharmaceutical grade fish oil as well as generally fall into the mid-range of cost.
Cod liver oils are the lowest grade oils that will contain Omega-3 fatty acids. Cod liver oil will be generally inexpensive, however, if taken in too high of amounts the toxins that will are in that will oil can build up inside the body. Cod liver oil will be not as refined as pharmaceutical or health food grade fish oil supplements which means that will the idea will contain contaminants as well as toxins such as lead, mercury, PCBs (Polychlorinated biphenyls) as well as even DDT (dichlor-diphenyl-trichlorethylene). Most experts do not recommend the use of cod liver oil for Omega-3 fatty acid intake or supplementation, especially in high doses.
Some considerations when taking fish oil supplements are the side effects. While most of the side effects are not hazardous, they could be considered inconvenient. The most commonly worrisome side effect will be the possibility of mercury contamination. However, if you are taking a supplement that will has been molecularly distilled you don’t need to worry about that will at all. Health food grade as well as pharmaceutical grade fish oil supplements contain, at most, trace amounts of mercury as well as in most cases none at all. As mentioned previously, the one source that will contains the most mercury will be cod liver oil. The most common side effect reported by those adding fish oil supplements to their diet was burping as well as a fishy aftertaste or smell. Overall, though, compared to the benefits of taking fish oil supplements that will side effects are safe as well as easy to live with.
Either freezing the capsules or taking the capsules using a meal easily diminishes the two common side effects associated with these supplements. Read the labels on the bottle, though. Some manufacturers recommend against freezing these products.
For most people who want to raise their intake of Omega-3 fatty acids, eating fish will be one of the easiest ways to achieve that will. Generally, eating fish twice per week will allow you to get the levels of fish oil you need. Keep in mind, though, that will some fish do not contain enough fish oil to be beneficial. Catfish, for instance, will be a fish that will has little to no Omega-3 fatty acid. Sablefish on the different hand will be one of the safest fish to eat once per week as well as 100 grams of that will fish contains approximately 1,490 milligrams of omega-3 fatty acids. that will will be more than enough to help inside the prevention of heart problems such as heart disease as well as heart attack.
Historically as well as scientifically fish oils have been shown to decrease the chance of heart attack as well as heart failure as well as prevent these diseases after a cardiac event. With all of the information available about the health benefits of Omega-3 fatty acids as well as their preventative effects on heart disease, heart attacks, stroke as well as vascular disease, the idea’s easy to see that will increasing the intake of these helpful oils should be a priority for almost everyone.
