Omega-3s to Lower Cholesterol

A 2015 study from Penn State University found that obese or overweight people had a 50% drop in LDL levels after following an avocado-rich, low-fat diet for five weeks. An earlier study from Mexico reported that a similar diet in healthy people with mild hypercholesterolemia reduced total cholesterol by 17% and “bad” LDL cholesterol by 22% after only seven days.

What To Know About Taking A Highly Concentrated Epa Supplements For Your Lipids

Not everyone at risk for cardiovascular disease needs a fish oil supplement highly concentrated in EPA. As discussed above, both EPA and DHA combined have been shown to significantly benefit heart and vascular health. Plus, there are many additional ways to lower LDL naturally while still taking fish oil high in both EPA and DHA. But if youve been taking fish oil and have noticed a negative effect on your LDL, consider trying a high-EPA fish oil for your cholesterol and cardiovascular health.

Anyone who has spent time perusing the seemingly endless brands of fish oil in their local store already knows EPA and DHA amounts vary tremendously between products. Always look for the specific amounts of EPA and DHA listed in the ingredients section of the label.

If you decide to try a fish oil highly concentrated in EPA to improve your lipids without raising LDL, aim for a total daily dose of at least 1800 mg EPA, based on evidence from clinical studies. Many high quality fish oil companies now selling fish oil capsules with enhanced amounts of EPA.

Should I Be Concerned About Mercury In Fish

Mercury occurs naturally in the environment and as a result of industrial pollution. It falls from the air and can collect in streams and oceans, where it is converted into methylmercury. Too much methylmercury can be harmful. This is especially true for unborn and young children.

Some fish have higher levels of mercury than others. These include shark, swordfish, tilefish, and King mackerel. Everyone should limit the amounts of these fish in their diet. Women who are pregnant or nursing and young children should not eat these types of fish. Women who are pregnant or nursing can safely eat 12 ounces of other types of fish each week. These include shellfish, canned fish and smaller fish.

Albacore Tuna has more mercury than canned light tuna. Limit the amount of albacore tuna you eat to 6 ounces per week.

What Is The Difference Between Good And Bad Cholesterol

Bad cholesterol, also known as low-density lipoprotein , will build up in the inner walls of your arteries, making them narrow. This slows down blood flow. If this buildup of plaque breaks off, a clot forms that can completely block the flow of blood, causing a heart attack.

Good cholesterol, also known as high-density lipoprotein , helps protect us from heart attacks and strokes. This type carries the bad cholesterol away from the arteries.

Importance Of Coq10 And Omega

Your body uses CoQ10 to help generate energy within each of your cells. CoQ10 is naturally consumed through food, including organ meats, beef, sardines, spinach and cauliflower, or is manufactured by your body. Your body’s CoQ10 production levels start to drop off after the age of 20, however.

Omega-3 is an essential fatty acid, meaning that it is vital for healthy growth but cannot be effectively synthesized by the body. Omega-3 is necessary for the construction of healthy cell membranes and is an important component of the myelin sheaths in the nervous system, the insulation on the wiring of the nerves.

Fish Oil Supplements: Heart

About 145 million Americans use nutritional supplements each yearthats almost one-half of the population. One of the most common is fish oil. They annually generate $1.2 billion in sales, according to Nutrition Business Journal. Manufacturers claim that these fish oil can lower your risk of cardiovascular diseases, improve immunity, and boost athletic performance. But what does the science say? In this article, the research of the effects of fish oil supplements on key health indicators in your bodyespecially triglycerides, cholesterol, and testosteronewill be critically evaluated.;

Fish Oil Research: Mixed Results

Low omega 3s cause heart attacks not cholesterol

Other studies have also looked at fish oil and cardiovascular health. The evidence has been mixed, partly because researchers used different types and quantities of fish oils and different placebos.

The 2007 JELIS trial also evaluated the use of EPA and statins and found a reduction in non-fatal coronary events. Major coronary events were reduced slightly in those with a history of coronary artery disease. No placebo was used.
The 2019;VITAL study used supplements including vitamin D3 and omega-3 fatty acids. It showed fish oil didnt lower the risk for major cardiac events.
The 2019 REDUCE-IT trial;evaluated icosapent ethyl , a high-dose pure EPA . The study included people with heart disease or people who were taking a statin medication with raised triglyceride levels. People on the omega-3 supplement had a 25% lower incidence of heart disease and stroke, and a 20% reduction in death from heart disease.

Where Do We Stand

Back to my patients who want to know if they should be taking an omega-3 supplement. With the availability of todays data, I would recommend a pure EPA supplement, or one that contains more EPA than DHA. But dont stop there. Eat a heart-healthy diet, get regular exercise, and pursue other lifestyle changes that have proven benefits for cardiovascular health. In the meantime, my colleagues and I wait for more definitive data on the utility of omega-3 fish oil, and who might benefit the most.

How Do Epa And Dha Benefit Heart Health

There is now strong evidence, according to Harvard researchers and many others, that EPA and DHA reduce the risk of cardiac death. Studies have found that EPA and DHA can lower your chances of suffering from a heart-related problem, like a heart attack, by 18%.

EPA and DHA lower your risk of getting heart disease or having a heart attack or stroke in part by improving your lipids, although they do not lower LDL naturally. Instead, their primary effect on lipids is to reduce triglycerides naturally. The triglyceride-lowering effect of EPA and DHA is now indisputable, based on many large, long-term, well-conducted studies.

Despite their excellent ability to reduce triglycerides naturally, EPA and DHA actually increase LDL cholesterol, concerning some doctors and medical researchers. All types of EPA/DHA seem to have this LDL-increasing effect, including prescription-based fish oil , over-the-counter fish oil supplements, and EPA/DHA supplements made from algae instead of fish.

Is The Ldl Increase By Dha Enough To Worry About

Many patients who are prescribed fish oil to reduce triglycerides naturally are already on a statin to lower their total and LDL cholesterol. For them, the fact that fish oil increases LDL isnt considered much of an issue, because a high enough dose of a powerful statin can counteract that increase. ;But there has been concern for those who are not taking statins, either because of personal preference or issues with side effects.; In these individuals, especially if they have high or borderline-high LDL, the LDL-increasing effects of DHA could be as much as 16%, resulting in increased risk of developing cardiovascular disease.; This is where taking a fish oil supplement formulated to contain very high amounts of EPA and low amounts of DHA may be especially useful.

The Good And Bad Of It All

There are two types of cholesterolLDL cholesterol is considered bad, and HDL is good.LDL cholesterol contributes to the buildup of fatty plaques in your arteries, which can interfere with blood flow.

Over time this causes high blood pressure and increases your risk of cardiovascular disease. HDL is considered good because it scavenges LDL and removes it from your blood, taking it back to your liver to be processed and then excreted.

Cholesterol can easily build up in your system because it is naturally produced by your body and can be ingested from certain animal products. Diets that are high in cholesterol like red meats, saturated fats, and whole-fat dairy products allow for excess cholesterol in your body.

When this happens, your HDL cholesterol has a difficult time scavenging all the LDL, and it accumulates to dangerous levels.

Triglycerides are fats that store excess energy from your diet. When combined with HDL or LDL, these fats cause the plaque accumulation in your arteries that leads to cardiovascular problems.

Because triglycerides can combine with both types of cholesterol and because HDL cannot scavenge all the LDL from your blood, the best approach to heart health is to reduce all levels. Dietary changes can achieve this, as can adding beneficial fatty acids to the mix.

You can always opt for a high-quality omega-3 supplement, but there are plenty of foods sources available to add to your diet. The best food sources for omega-3 fatty acids include:

Omega-3 fatty acids exert a dose-related effect on bleeding time; however, there are no documented cases of abnormal bleeding as a result of fish oil supplementation, even at high dosages and in combination with other anticoagulant medications.28 High dosages of fish oil may increase LDL cholesterol levels, but the clinical relevance of this finding remains unclear.14,15 Other potential side effects of omega-3 fatty acids include a fishy aftertaste and gastrointestinal disturbances, all of which appear to be dose-dependent.2

Significant amounts of methylmercury, polychlorinated biphenyls, dioxins, and other environmental contaminants may be concentrated in certain species of fish, such as shark, swordfish, king mackerel, and tile-fish .29 In March 2004, the U.S. Food and Drug Administration and the Environmental Protection Agency issued a new statement29 advising women who may become pregnant, women who are pregnant, breastfeeding mothers, and young children to avoid eating some types of fish and to eat fish and shellfish that are lower in mercury. These recommendations29; are summarized in Table 3 . According to a recent survey,30 farmed salmon have significantly higher levels of polychlorinated biphenyls and other organochlorine contaminants than wild salmon. There is disagreement among researchers, however, about the amount of farmed salmon that is safe to eat. High-quality fish oil supplements usually do not contain these contaminants.

Do They Have A Direct Relationship With Cholesterol

As there are mixed reviews on how omega-3 and omega-6 fatty acids affect cholesterol, its best to lay out all the knowledge and findings out there. While the American Heart Association and Heart Foundation, claim that consuming polyunsaturated fats help increase HDL levels and lower LDL levels , it may be the case that not all polyunsaturated fats are considered equal. According to the International Food Information Council Foundation, omega-3 fatty acids decrease serum triglyceride and total cholesterol levels, and may increase or have no effect on high-density-lipoprotein cholesterol, while diets high in omega-6 fatty acids are associated with lower blood levels of total cholesterol and LDL-cholesterol, but also with lower blood levels of the protective HDL cholesterol. Overall, this means that our bodies may be out of sync in our omega-3 to omega-6 balance. Omega-3 seems to have a better outlook for healthy HDL levels than omega-6, which focus more on LDL levels.

Other Sources Of Omega

Oily fish, such as salmon and tuna, contain 2 kinds of omega-3s. These are EPA and DHA. Both have direct benefits for your heart.

You can get another kind of omega-3, ALA, in some oils, nuts, and plants. ALA benefits your heart, but not as directly as EPA and DHA. Still, eating nuts, seeds, and healthy oils as well as fish can help you get a full range of these healthy fats.

Plant-based sources of omega-3s include:

Canola oil and soy oil
Soybeans and tofu

Of all plant-based foods, ground flaxseeds and flaxseed oil have the highest amount of ALA. You can eat ground flaxseed over granola or in smoothies. Flaxseed oil goes well in salad dressing.

What Foods Should I Eat What Foods Should I Avoid

Using Omega 3 to lower your blood pressure and cholesterol naturally

Maintaining a healthy diet can help lower your cholesterol. Recommended foods include fruits and vegetables; whole grain foods; fat-free, 1%, or low-fat milk products; poultry without skin and lean meats; fatty fish such as salmon, trout, albacore tuna, and sardines; and unsalted nuts, seeds, and legumes.

A diet high in cholesterol, saturated fats, and trans fats should be avoided. This includes high-sodium foods; sweetened or sugary beverages; red, fatty, or processed meats; full-fat dairy products; baked goods with saturated and trans fats ; solid fats or fried foods; and hydrogenated and saturated oils.

Cardiovascular disease remains the leading cause of mortality and morbidity in the United States, with coronary artery disease being the number-one cause of death.1 Dyslipidemia is a major contributor to the development of CAD and other forms of atherosclerosis; individuals with high total cholesterol levels have about twice the risk for heart disease. Approximately 100 million adults in the U.S. have total cholesterol levels >200 mg/dL , and almost 74 million have high levels of low-density lipoprotein cholesterol .2,3 Adults aged >20 years should have their cholesterol measured at least once every 5 years.2

Against High Cholesterol And Arteriosclerosis

Fish oil seems to slow or slightly reverse the progress of atherosclerosis in the arteries that supply blood to the heart and helps reduce bad cholesterol by limiting its absorption in the intestine. Moreover, according to the National Library of Medicine , the cholesterol-lowering ability of fish oil is boosted when combined with vitamin B12 intake. It also increases the good cholesterol that needs to high to be heart-protective.

What If Im Allergic To Fish Or Dont Want To Eat Fish

Fish is the best food source of omega-3 fatty acids, but several plants contain ALA. This is not as rich of a source of omega-3 fatty acids, but some studies show that ALA can reduce the risk of cardiovascular disease.

Good sources of ALA are ground or milled flaxseeds, flaxseed oil, chia seeds, walnuts, soy foods and canola oil. Another source of ALA is algae or algae oil, which is broken down to DHA. Many foods that are fortified with omega-3 use algae oil. These are excellent options for vegetarians that do not eat fish.

There are currently no serving size recommendations for ALA-rich foods. But, adding these foods to your diet regularly may help your heart health.

What Exactly Is Fish Oil

Fish oil supplements contain oils derived from the skin and liver of fatty fish such as mackerel, tuna, sardines, and salmon. They are an excellent source of omega-3 fatty acids, a polyunsaturated fat that helps protect against heart disease and possibly other health conditions . Omega-3 fatty acids come in three varieties. One is alpha-linolenic acid , found in vegetable oils such as soybean, canola, and walnut. The other two are eicosapentaenoic acid and docosahexaenoic acid , only found in fatty fish and fish-derived supplements. Though Omega-3 fatty acids are essential to humans, they cannot be produced by the body and must be consumed through diet or supplementation. Unfortunately, most Americans dont get enough of any of these types of omega-3 fatty acids in their diets.;So, many people look to fish oil supplements to gain their daily recommended value of omega-3 fatty acids and gain its heart-healthy benefits.;

Cardiac Mortality Sudden Death And All

The Diet and Reinfarction Trial 4 was one of the first studies to investigate a relationship between dietary intake of omega-3 fatty acids and secondary prevention of myocardial infarction. In this study, 1,015 men were advised to eat at least two servings of fatty fish per week, and 1,018 men were not so advised. At the two-year follow-up, the men who had been advised to consume fish had a 29 percent reduction in all-cause mortality but no reduction in the incidence of myocardial infarction.4

Sudden death caused by sustained ventricular arrhythmias accounts for 50 to 60 percent of all deaths in persons with coronary heart disease .5 To date, the largest, prospective, randomized controlled trial on the effects of omega-3 fatty acids is the GISSI-Prevenzione Trial.6 This study included 11,324 patients with known CHD who were randomized to receive either 300 mg of vitamin E, 850 mg of omega-3 fatty acids, both, or neither. After three and one-half years, the group given omega-3 fatty acids alone had a 45 percent reduction in sudden death and a 20 percent reduction in all-cause mortality.6
