Therefore grass-fed beef, though a source of ALA, is not a significant contributor of omega-3 fat in our diets. Source: 1 , 2 , 3 , 4 , 5 via USDA National Nutrient Database for Standard Reference, Legacy Most Americans take in far more of another essential fat—omega-6 fats—than they do omega-3 fats.

Like omega-3 fats, omega-6 fats are a critical part of the structure of every cell of our body and are building blocks for hormones that regulate inflammation, narrowing of blood vessels, and blood clotting. Normally, these are important functions that protect the body from injury and infection, but a popular claim is that an excess intake of omega-6 fats can over-stimulate these functions, causing more harm than benefit.

In addition, because omega-3 and omega-6 fats compete for the same enzymes to produce other fatty acids, it is believed that eating an excess of one type may interfere with the metabolism of the other, thereby reducing its beneficial effects.

Many studies and trials in humans support cardiovascular benefit of omega-6 fats. There is no question that many Americans could benefit from increasing their intake of omega-3 fats, but there is also evidence that omega-6 fats reduce cardiovascular risk factors and heart disease.

Like many essential nutrients, it is possible that too much can cause problems. However in the U. diet, we have not been able to find individuals or groups who are consuming excessive amounts of omega-6 fatty acids.

ALA: Alpha-linolenic acid ALA , the most common omega-3 fatty acid in most Western diets, is found in plant oils especially canola, soybean, flax , nuts especially walnuts , chia and flax seeds, leafy vegetables, and some animal fats, especially from grass-fed animals.

ALA is a true essential fat because it cannot be made by the body, and is needed for normal human growth and development.

It can be converted into EPA and DHA, but the conversion rate is limited so we are still uncertain whether ALA alone can provide optimal intakes of omega-3 fatty acids. Is grass-fed beef a good source of omega-3 fats?

What is conjugated linoleic acid CLA? This is a type of omega-6 fat found naturally in dairy, beef, and vegetable oils. It is also a popular dietary supplement, produced by chemically changing the structure of polyunsaturated vegetable oils.

CLA supplements have been researched as a weight loss aid by reducing body fat; however findings have conflicted. Some studies show a modest short-term weight loss while others show no weight changes. Some reported negative side effects include loose stools and fatty liver that may occur when taken in high dosages in supplements.

Currently, most clinicians do not assess omega-3 status, but it can be done by measuring individual omega-3s in plasma or serum phospholipids and expressing them as the percentage of total phospholipid fatty acids by weight [ ].

Experts have not established normal ranges, but mean values for serum or plasma phospholipid EPA plus DHA among U. Plasma and serum fatty acid values, however, can vary substantially based on an individual's most recent meal, so they do not reflect long-term dietary consumption [ 3 , 17 ].

It is also possible to assess omega-3 status via analysis of erythrocyte fatty acids, a measurement that reflects longer term intakes over approximately the previous days [ 18 , 19 ]. The omega-3 index proposed by Harris and von Schacky reflects the content of EPA plus DHA in erythrocyte membranes expressed as a percentage of total erythrocyte fatty acids [ 20 , 21 ].

This index can be used as a surrogate for assessing tissue levels of EPA plus DHA [ 16 , 22 , 23 ]. In Japan, where fish consumption is high, erythrocyte EPA and DHA levels are about twice those of Western populations [ 3 ].

Intake recommendations for fatty acids and other nutrients are provided in the Dietary Reference Intakes DRIs developed by the Food and Nutrition Board of the Institute of Medicine IOM now called the National Academy of Medicine [ 5 ]. DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people.

These values, which vary by age and sex, include the following:. When the IOM last reviewed omega-3s, insufficient data were available to establish an EAR, so the IOM established AIs for all ages based on omega-3 intakes in healthy populations [ 5 ].

Table 1 lists the current AIs for omega-3s in grams per day. Human milk contains omega-3s as ALA, EPA, and DHA, so the IOM established an AI for infants from birth to 12 months that is equivalent to the mean intake of omega-3s in healthy, breastfed infants.

For infants, the AIs apply to total omega-3s. For age 1 and older, the AIs apply only to ALA because ALA is the only omega-3 that is essential. The IOM did not establish specific intake recommendations for EPA, DHA, or other LC omega-3s. Plant oils that contain ALA include flaxseed linseed , soybean, and canola oils [ 2 , 3 ].

Chia seeds and walnuts also contain ALA. The omega-3 content of fish varies widely. Cold-water fatty fish, such as salmon, mackerel, tuna, herring, and sardines, contain high amounts of LC omega-3s, whereas fish with a lower fat content—such as bass, tilapia, and cod—as well as shellfish contain lower levels [ 3 ].

The omega-3 content of fish also depends on the composition of the food that the fish consumes [ 24 ]. Farmed fish usually have higher levels of EPA and DHA than wild-caught fish, but it depends on the food they are fed [ 24 , 25 ].

An analysis of the fatty acid composition of farm-raised Atlantic salmon from Scotland showed that the EPA and DHA content significantly decreased between and due to the replacement of traditional marine ingredients in fish feed with other ingredients [ 26 ].

Beef is very low in omega-3s, but beef from grass-fed cows contains somewhat higher levels of omega-3s, mainly as ALA, than that from grain-fed cows [ 27 ]. Some foods, such as certain brands of eggs, yogurt, juices, milk, and soy beverages, are fortified with DHA and other omega-3s.

Since , manufacturers have added DHA and arachidonic acid the two most prevalent LC PUFAs in the brain to most infant formulas available in the United States [ 28 ]. The U. Food and Drug Administration FDA has established a Daily Value DV of 65 g for total fat but not for omega-3s.

Thus, Table 2 presents the amounts of omega-3 fatty acids in grams per serving only and not the percent of the DV. Department of Agriculture USDA database does not specify whether fish are farmed or wild caught.

The USDA's FoodData Central website [ 29 ] lists the nutrient content of many foods and provides a comprehensive list of foods containing ALA arranged by nutrient content and by food name , foods containing DHA arranged by nutrient content and by food name , and foods containing EPA arranged by nutrient content and by food name.

LC omega-3s are present in several dietary supplement formulations, including fish oil, krill oil, cod liver oil, and vegetarian products that contain algal oil.

A typical fish oil supplement provides about 1, mg fish oil, containing mg EPA and mg DHA, but doses vary widely [ 30 ]. Cod liver oil supplements provide vitamin A and vitamin D in addition to LC omega-3s. Although seafood contains varying levels of methyl mercury a toxic heavy metal [ 31 ], omega-3 supplements have not been found to contain this contaminant because it is removed during processing and purification [ 32 ].

Dietary supplements can contain several different forms of omega-3s, including natural triglycerides, free fatty acids, ethyl esters, re-esterified triglycerides, and phospholipids [ ]. Natural triglycerides are the form that occur naturally in fish oil, whereas ethyl esters are synthesized from natural triglycerides by replacement of the glycerol molecule of the triglyceride with ethanol.

Re-esterified triglycerides are formed by the conversion of ethyl esters back to triglycerides. Omega-3s as re-esterified triglycerides, natural triglycerides, and free fatty acids have somewhat higher bioavailability than ethyl esters, but consumption of all forms significantly increases plasma EPA and DHA levels [ 33 , 35 ].

Krill oil contains omega-3s primarily as phospholipids. Some studies suggest that these phospholipids have somewhat higher bioavailability than the omega-3s in fish oil, whereas other studies do not [ 34 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ].

Plant-based sources of omega-3s from algal oil usually provide around — mg DHA; some contain EPA as well. These supplements typically contain omega-3s in the triglyceride form [ 32 ].

According to a small study, the bioavailability of DHA from algal oil is equivalent to that from cooked salmon [ 43 ]. Formulations of omega-3 dietary supplements vary widely, so it is important to check product labels to determine the types and amounts of omega-3s in these products.

The Dietary Supplement Label Database from the National Institutes of Health contains label information from many dietary supplements on the market that contain omega-3s. According to data from the — National Health and Nutrition Examination Survey NHANES , most children and adults in the United States consume recommended amounts of omega-3s as ALA [ 44 ].

Among children and teens age 2—19 the average daily ALA intake from foods is 1. In adults age 20 and over, the average daily ALA intake from foods is 1. Consumption of DHA and EPA from foods contributes a very small amount to total daily omega-3 intakes about 40 mg in children and teens and about 90 mg in adults [ 44 ].

Use of dietary supplements containing omega-3s also contributes to total omega-3 intakes. adults and children [ 45 , 46 ]. Data from the National Health Interview Survey indicate that 7. adults and 1. According to an analysis of — NHANES data, use of these supplements adds about mg to mean daily ALA intakes, 10 mg to mean DHA intakes, and 20 mg to mean EPA intakes in adults [ 47 ].

A deficiency of essential fatty acids—either omega-3s or omega-6s—can cause rough, scaly skin and dermatitis [ 5 ]. Plasma and tissue concentrations of DHA decrease when an omega-3 fatty acid deficiency is present.

However, there are no known cut-off concentrations of DHA or EPA below which functional endpoints, such as those for visual or neural function or for immune response, are impaired. Evidence that higher LC omega-3 levels are associated with a reduced risk of several chronic diseases, including coronary heart disease, suggests that many Americans could benefit from slightly higher intakes.

However, classical essential fatty acid deficiency in healthy individuals in the United States is virtually nonexistent [ 5 ]. During periods of dietary-fat restriction or malabsorption accompanied by an energy deficit, the body releases essential fatty acids from adipose-tissue reserves.

For this reason, clinical signs of essential fatty-acid deficiency are usually only found in patients receiving parenteral nutrition that lacks PUFAs. This was documented in case reports during the s and s [ 5 ], but all current enteral and parenteral feeding solutions contain adequate levels of PUFAs.

The potential health benefits of consuming omega-3s are the focus of a great deal of scientific research. By far, the majority of research has focused on EPA and DHA from foods e. Many observational studies link higher intakes of fish and other seafood with improved health outcomes.

However, it is difficult to ascertain whether the benefits are due to the omega-3 content of the seafood which varies among species , other components in the seafood, the substitution of seafood for other less healthful foods, other healthful behaviors, or a combination of these factors.

Data from randomized clinical trials are needed to shed light on these questions. This section focuses on areas of health in which omega-3s might be involved: CVD and its risk factors ; infant health and neurodevelopment ; cancer prevention ; Alzheimer's disease, dementia, and cognitive function ; age-related macular degeneration ; dry eye disease ; rheumatoid arthritis ; and other conditions.

Many studies have assessed the effects of omega-3s—primarily EPA and DHA—on CVD and CVD risk factors, such as high blood pressure and elevated plasma lipids. This interest was spurred by epidemiological research dating back to the s that found low rates of myocardial infarction and other coronary events among Greenland Inuit and other fish-eating populations, such as those in Japan [ 3 ].

Results from observational studies have been consistent with these findings, with several systematic reviews and meta-analyses showing that higher consumption of fish and higher dietary or plasma levels of omega-3s are associated with a lower risk of heart failure, coronary disease, and fatal coronary heart disease [ 48 , 49 ].

The authors of a systematic review that included six secondary-prevention trials and one primary-prevention trial of omega-3 supplementation published between and concluded that consumption of LC omega-3s from fish and fish oil supplements reduces rates of all-cause mortality, cardiac death, sudden death, and stroke [ 50 ].

They noted that the evidence of benefit is stronger for secondary than for primary prevention. Results from the Japan EPA Lipid Intervention Study in supported the growing body of evidence that LC omega-3s reduce the risk of heart disease, especially in people with a history of coronary artery disease [ 56 ].

After a mean of 4. The EPA group also experienced a significant reduction in rates of unstable angina and nonfatal coronary events but not in rates of sudden cardiac death or coronary death in comparison with the control group.

In an analysis of the primary prevention subgroup from this study participants with no history of coronary artery disease , EPA supplementation had no significant effects on any outcome. Several subsequent clinical trials, however, had largely null findings [ ].

For example, the Outcome Reduction with an Initial Glargine Intervention ORIGIN trial included 12, patients who had diabetes or a high risk of diabetes and a high risk of cardiovascular events.

Scientists gained additional insight into the effects of omega-3s for the primary prevention of CVD, including in patients with diabetes, from two trials: VITamin D and OmegA-3 TriaL VITAL and A Study of Cardiovascular Events in Diabetes ASCEND [ 61 , 62 ].

VITAL included 25, men age 50 and older and women age 55 and older with no previous heart attacks, strokes, or cancer, whereas ASCEND included 15, adults age 40 or older with diabetes but no evidence of CVD.

In VITAL, the omega-3 supplement did not significantly reduce the rate of major cardiovascular events combined myocardial infarction, stroke, and cardiovascular mortality after a median of 5. Supplement users also had significant reductions in rates of fatal myocardial infarction, total coronary heart disease, and percutaneous coronary intervention a procedure that widens blocked or narrowed coronary arteries.

No significant reductions in stroke or death rates from cardiovascular causes were observed. ASCEND had similar findings [ 61 ]. After a mean follow-up of 7.

The Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial REDUCE-IT found significant CVD benefits with Vascepa, a high-dose, prescription form of omega-3s containing EPA in the form of icosapent ethyl IPE , an ethyl ester [ 63 ].

REDUCE-IT included 8, participants with CVD age 45 years or older or with diabetes and at least one other risk factor age 50 years or older. A subsequent clinical trial known as STRENGTH Long-Term Outcomes Study to Assess Statin Residual Risk with Epanova in High Cardiovascular Risk Patients with Hypertriglyceridemia found no significant CVD benefits with Epanova, a high-dose, prescription form of omega-3s containing EPA and DHA in a carboxylic acid form omega-3 CA [ 64 ].

STRENGTH included 13, participants from 22 countries mean age However, the trial was stopped after participants were treated for a median of about 3. Omega-3 CA did not significantly reduce the composite end point of cardiovascular death, myocardial infarction, stroke, coronary revascularization, or hospitalization for unstable angina.

The omega-3 form, study population, background dietary omega-3 intakes, and use of statins and other cardioprotective therapies might explain some conflicting findings among studies [ 17 , 59 , 60 , ].

In addition, dose probably plays a major role in the ability of omega-3 supplementation to confer significant benefits [ 65 ]. The REDUCE-IT findings suggest that a high daily dose of IPE, 4 g, is an effective adjunct to statin therapy in people with CVD or a high risk of CVD [ 63 ].

The daily dose of 1 g used in many studies of omega-3 dietary supplements might affect some CVD pathways [ 65 ] but has had no significant effect on the primary outcomes in several trials [ 59 , 61 , 62 ]. The reasons for the different results are not clear, but a partial explanation—beyond differences in the omega-3 formulation ethyl ester EPA vs.

carboxylic acid EPA and DHA and the baseline health of the study population—may lie with the different placebo comparators used, mineral oil in REDUCE-IT and corn oil in STRENGTH [ 64 , 73 , 74 ].

Mineral oil is not a neutral placebo; it affects lipid levels and inflammatory markers and may inhibit the absorption of statin drugs.

Therefore, in REDUCE-IT, differences in CVD events between the treatment and placebo groups would likely be smaller if a more neutral placebo oil had been used. Furthermore, in the clinical trials mentioned above, the effects of LC omega-3s are not uniform across CVD outcomes. Therefore, use of primary composite endpoints that combine multiple outcomes might dilute significant effects on individual components of those endpoints [ 67 ].

A systematic review and meta-analysis of 13 trials included ASCEND, VITAL, and REDUCE-IT but not STRENGTH and a total of , participants [ 67 ].

LC omega-3 doses ranged from 0. The authors concluded that LC-omega-3 supplementation reduces the risk of myocardial infarction, coronary heart disease death, total coronary heart disease, CVD death, and total CVD and the effects appear to be dose related. However, the findings showed no significant associations for risk of fatal and nonfatal stroke.

A Cochrane Review of 86 randomized controlled trials published between and found that 0. However, the supplements did not affect all-cause mortality, cardiovascular events, stroke, or arrhythmia.

The authors of several earlier meta-analyses and systematic reviews, as well as a report from the Agency for Healthcare Research and Quality AHRQ , concluded that omega-3 supplements do not appear to significantly reduce the risk of most cardiovascular events [ , ].

Many of these analyses [ , ], however, but not all [ 80 , 87 ], did find that omega-3s reduce the risk of cardiac death. Between and , the American Heart Association AHA released three science advisories on omega-3s [ 66 , 88 , 89 ]. ALA is mainly found in plants, while DHA and EPA occur mostly in animal foods and algae.

Common foods that are high in omega-3 fatty acids include fatty fish, fish oils, flax seeds, chia seeds , flaxseed oil, and walnuts. For people who do not eat much of these foods, an omega-3 supplement , such as fish oil or algal oil, is often recommended. Omega-3 fatty acids are a family of important fats that you must obtain from your diet.

The three main types are ALA, EPA, and DHA. Alpha-linolenic acid ALA is the most common omega-3 fatty acid in your diet 3. Your body mainly uses it for energy, but it can also be converted into the biologically active forms of omega-3, EPA and DHA. However, this conversion process is inefficient.

Only a small percentage of ALA is converted into the active forms 4 , 5 , 6. ALA is found in foods like flax seeds, flaxseed oil, canola oil, chia seeds, walnuts, hemp seeds , and soybeans. Eicosapentaenoic acid EPA is mostly found in animal products, such as fatty fish and fish oil.

However, some microalgae also contain EPA. Docosahexaenoic acid DHA is the most important omega-3 fatty acid in your body. Like EPA, it occurs mainly in animal products like fatty fish and fish oil. Meat, eggs, and dairy from grass-fed animals also tend to contain significant amounts.

Vegetarians and vegans often lack DHA and should take microalgae supplements to make sure they get enough of this omega-3 8 , 9. The three main omega-3 fatty acids in your diet are ALA, EPA, and DHA.

While the latter two are primarily found in animal foods, ALA occurs in many plant foods. Both are used to produce signaling molecules called eicosanoids, which have various roles related to inflammation and blood clotting Yet, omega-3s are anti-inflammatory , and scientists hypothesize that eating too much omega-6 counteracts these beneficial effects.

In the Western diet, omega-6 intake is very high compared to that of omega-3s, so the ratio is currently skewed far towards the omega-6 side Maintaining a balance between these two fats — often termed the omega-6 to omega-3 ratio — may be important for optimal health. Although insufficient evidence exists to show that omega-6 is harmful, most health professionals agree that getting enough omega-3 is important for health Omega-3 and -6 fats are used to produce important signaling molecules called eicosanoids.

Balancing your intake of these fatty acids is considered important for optimal health. Omega-3 fatty acids, particularly DHA, are vital for your brain and retinas 7. It is particularly important for pregnant and breastfeeding women to get enough DHA, as it can affect the health and intelligence of the baby Additionally, sufficient omega-3 intake can have powerful health benefits for adults.

This is especially true of the longer-chain forms, EPA and DHA. Although evidence is mixed, studies indicate that omega-3 fatty acids can protect against all sorts of illnesses, including breast cancer, depression, ADHD, and various inflammatory diseases 14 , 15 , 16 , Omega-3 Fatty acids and pregnancy.
