Facts & Health Benefits Of Omega-3 DHA

Facts & Health Benefits Of Omega-3 DHA
Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs), which are long chains of carbon atoms with a carboxyl group at one end of the chain and a methyl group at the other. They are distinguished from saturated and monounsaturated fatty acids by the presence of two or more double bonds between carbons within the fatty acid chain.
Omega-3 fatty acids are an integral part of the structure of the cell membrane throughout the body, they are especially high in the brain and retina. They have wide functions in the body’s cardiovascular, immune, eye, cognitive function, joint, and muscle function. Omega-3s can benefit health in a number of ways, they function as building blocks of hormones, reduce cholesterol, maintain skin health, regulate inflammation, support brain, and mood issues.
Omega-3s are important nutrients one must consider getting on a daily basis from diet and supplements.
Did you know? Omega-3 fatty acids are called so because their first double bond is placed at the third carbon atom when counting from the methyl end of the fatty acid. Omega-3 fatty acids are also named “vitamin F” from “fatty acids”.
 

WHAT ARE SOME OF THE FOOD SOURCES OF OMEGA-3 DHA?

Facts & Health Benefits Of Omega-3 DHA
Omega-3 fatty acids like ALA are found in flaxseed, soybeans, canola oil, chia seeds, walnuts.
The omega-3 EPA and DHA can be found in marine food sources like salmon, tuna, sardines, crustaceans, krill, mackerel. Other important marine sources of omega-3 polyunsaturated fatty acids include sea life such as autotrophic macroalgae, microalgae.
Some foods like eggs, yogurt, juices, milk, soy beverages are fortified with DHA and other omega-3s.

 

WHAT IS THE DIFFERENCE BETWEEN ALA, EPA & DHA? 

Facts & Health Benefits Of Omega-3 DHA
All three are omega-3 fatty acids with the being ALA is found only in plant sources, whereas EPA and DHA are found in animal foods and algae. The polyunsaturated fatty acids vary structurally in terms of the number of carbon atoms and double bonds. ALA is known as C-18:3n-3 because it is an omega-3 fatty acid that has 18 carbons and 3 double bonds, EPA is known as C-20:5n-3 because this omega-3 fatty acid has 20 carbon atoms with 5 double bonds and DHA is represented as C22:6n-3 because it’s an omega-3 fatty acid which has 22 carbon atoms with 6 double bonds. The best source of omega-3 fatty acid is DHA and EPA. Omega-3 DHA is the solution to bioavailable omega-3s. Our body can utilize them well without any conversion or modification.

 

WHAT IS THE NEED TO SUPPLEMENT WITH OMEGA-3 DHA?

Facts & Health Benefits Of Omega-3 DHA
Omega-3s are classified as essential polyunsaturated fatty acids as our body can’t make them and need to be obtained from food or supplements. The human body can make most of the types of fats it needs but that’s not the case for omega-3 fatty acids. Humans do not possess an enzyme required to synthesize omega-3 fatty acids. Our body can obtain the shorter-chain omega-3 fatty acids such as alpha-linoleic acid (ALA) consisting of 18 carbon and three double bonds and later use them to produce eicosapentaenoic acid (EPA) which is considered to be a more important fatty acid that consists of 20 carbon and five double bonds. From EPA, they further synthesize docosahexaenoic acid (DHA), which is considered more crucial and consists of 22 carbons and six double bonds. However, research has found that conversion of DHA from ALA is insignificant, which suggests the importance of dietary intake of DHA.
Consumption of DHA and EPA from foods doesn’t contribute much to total daily omega-3 intakes. Therefore, getting DHA from dietary supplements is the convenient and practical way to increase levels of these omega-3 fatty acids in the body.

WHY DO VEGANS PARTICULARLY NEED OMEGA-3 SUPPLEMENTS?

Facts & Health Benefits Of Omega-3 DHA

Vegan DHA supplement obtained from microalgae may be a particularly important consideration for vegetarians and vegans to obtain adequate levels of the important nutrient. A vegan and vegetarian diet consists exclusively plant-based diet and omega-3s found in plant sources is ALA. Plant foods do not contain EPA or DHA.  The ALA in plant foods can be metabolized into EPA and DHA in the liver but this conversion is limited in humans, moreover, factors like stress, aging, illness, and diet can impair this process. If you are eating a varied plant-based diet, then it is likely that you are consuming good sources of ALA on a regular basis, however, eating enough ALA may require more planning.

Omega-3 DHA can help reduce morning stiffness, can offset free radical damage, helps blood flow efficiently to the muscles, make muscles stronger and resilient.

 

OMEGA-3 DHA BENEFITS HEART HEALTH

Facts & Health Benefits Of Omega-3 DHA
High levels of triglycerides have been linked with fatty acid buildup in the artery walls, which increase the risk of heart ailments. There is consistent research evidence to show omega-3s ability to decrease levels of triglycerides by increasing the rate of beta-oxidation, by acting specifically on carnitine acetyltransferase 1 (CAT 1) and acetyl-CoA carboxylase. Omega-3s particularly DHA can decrease mitochondrial oxygen consumption without reducing power generation for the ventricles by altering mitochondrial membrane phospholipid composition, protecting the heart from tiring. Omega-3 DHA has a favourable effect in improving endothelial function, maintaining normal blood pressure, reduce inflammatory markers, reduce plaque buildup in the arteries, decrease the risk of abnormal heart rhythm and decrease the risk of atherosclerosis.
 

OMEGA-3 DHA SUPPORTS HEALTHY VISION

Facts & Health Benefits Of Omega-3 DHA
DHA is found in high concentration in the retina, the part of the eye that is responsible for visual recognition, suggesting it has an important function in sending signals to the brain. Those with low levels of DHA may suffer from visual impairment and degradation of the retina. Omega-3 DHA provides antioxidant protection to the eyes, has a protecting role in reducing the onset and progression of retinal and vision problems. DHA optimizes fluidity of photoreceptor membranes, retinal integrity, reduces the risk of age-related macular degeneration. Omega-3s have cytoprotective effects in the retina and may help prevent symptoms of dry eyes that can include a stinging, itchy, burning sensation in the eyes and sensitivity to light which is commonly seen in older women.
