Which is More Important? Although both DHA and EPA are important to health, it has not been known whether EPA or DHA was primarily responsible for lower triglyceride levels when consumed at proper ratios. A recent study conducted at the USDA-ARS Western Human Nutrition Center found that high levels of EPA (found in fish oil) offered benefits but also increased bleeding times. DHA, however, was shown beneficial for participants in the study showing decreased tryglyceride levels after 4 months of about 26%.* These same volunteers also showed a rise of almost 9% in HDL cholesteral, the good cholesterol.* This study also found an increase of 69% of apoprotein-E, the compound that carries cholesteral from peripheral tissues back to the liver for breakdown and excretion.* Read More. Note: The ratio of EPA to DHA is very important when considering which supplements to buy. Not all results are the same and the numbers referred to may be from a single study, presented here for discussion purposes only. Most fish oil products contain more EPA than DHA. Yet DHA may offer the most direct source of DHA and DHA should be present in higher concentrations. The ratio of DHA to EPA is very important. EPA and DHA are essential fatty acids that the human body is unable to easily get on its own or through foods. Marine omega-3 oils contains both EPA and DHA fatty acids. Our bodies need certain fats to carry fat-soluble vitamins like A,D, and K and to make steriod hormones, keep skin healthy and to perform other biochemical chores. Much of our essential fatty acids must be consumed through food or supplements to provide the body what it needs. This vital nutrient is equally important for keeping metabolism regulated by maintaining blood fats called triglycerides. Your liver controls and recycles your triglycerides and cholesterol as it works to maintain your body's health. When you eat too much, or eat the wrong foods, the liver and other organs get overworked and overloaded. Kids omega-3 and children's omega-3s in food and supplements should be mainly DHA omega-3, suggested for children. We optimized our oil using SOURCE OIL. Omega-3 fatty acids are most notably the bioactive lipids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Certain fish and microalgae contain high levels of the essential bioactive omega-3 products EPA and DHA. Plants also make various levels of omega-3 fatty acid precursors. Other dietary long chain fatty acids are the omega-6 fatty acids. Linoleic acid (LA) is the main omega-6 precursor in plant and vegetable oils. The omega-6 fatty acid arachidonic acid (AA) is bioactive and found in red meat. The balance of omega fatty acids is important to consider. The so-called omega-3 : omega-6 ratio has become a model for gauging the proper balance of these fats in oils and the diet. Diets with greater than a 1:10 ratio of omega-3 to omega-6 are not recommended, whereas a 1:1 ratio is considered perfect. Very unhealthy ratios of 1:25 and 1:50 are found to be common, especially with regular consumption of 'fast-food', high amounts of fried food, and low intake of fresh whole foods. Thus, 'Eating to live and not living to eat' becomes an important consideration with increases in modern, convenient, non-functional food choices. The fatty acids of major interest in the diet are named so n-3 indicates omega-3 and n-6 indicates omega-6. Notably, EPA n-3 and AA n-6 are the same length with 20 carbons each. However, EPA is unsaturated at the n-3 position providing signaling and metabolic specificity between AA and EPA. AA is converted into inflammatory compounds, but the unique n-3 bond means EPA is converted into dramatically different bioactive products. In addition, EPA may compete directly with AA for many of the same enzymes during the inflammatory process. The other important omega-3, DHA n-3, has 22 carbons, is unsaturated at n-3 and is significant for affecting triglyceride levels, by as yet undefined mechanisms. DHA is also incorporated into membrane phospholipids in the brain and eye and DHA is concentrated at neuron terminals.

Masne kiseline, tačnije esencijalne masne kiseline su one koje moramo uneti u naš organizam putem hrane, zato što ih on sam ne može stvoriti. U ovoj grupi najviše se izdvajaju, a svakako su i najpoznatije omega-3 i omega-6 masne kiseline. One su jako važne za normalno funkcionisanje mozga, smanjenje rizika od bolesti, a pozitivno utiču na rast i razvoj. Omega masne kiseline su polinezasićene masne kiseline, koje se mogu podeliti: Najviše je ima u ribi (losos, bakalar, skuša, pastrmka, sardina, tuna) i ribljem ulju. Svi znamo da se preporučuje najmanje jedna nedeljno riba na našem jelovniku, ali zašto? Upravo zbog toga sto je bogata ovim esencijalnim masnim kiselinama. Omega-3 masne kiseline ključne su za zdravlje zglobova i srca, snižavaju loš holesterol (LDL), a istovremeno povećavaju onaj dobar (HDL). Učestvuju u sastavu ćelijske membrane gde regulišu funkciju ćelijskih receptora, a neka istraživanja kazu da sprečavaju kancoregene bolesti. Omega-3 su sirovina za sintezu hormona, sprečavaju zgrušavanje krvi, artritis, depresiju, smanjuju rizik od srčanih bolesti i šloga, smanjuju menstrualne bolove, sprečavaju rizik od osteoporoze, regulišu rad želuca i creva, i još mnogo mnogo toga. Naš mozak je zavisan od DHA kiseline, jer smanjenje i nedostatak ove kiseline može dovesti do depresije, šizofrenije, ili nastanka Alchajmerove bolesti. Nedostatak može dovesti i do naglih promena raspoloženja – smanjuje se seratonin, hormon odgovoran za naše dobro raspoloženje i osećaj sreće. Ovih nutrijenata najviše ima u biljnim uljima, lanenom semenu, orasima, crnoj ribizli, sojinom ulju, jezgrastom voću i semenkama. Najvažnije omega-6 masne kiseline su linolna (LA), gama-linolenska (GLA) i dugolančana arahidonska kiselina (AA). LA je esencijalna masna kiselina koju organizam ne može da sintetiše, već se unosi hranom, a GLA i AA u organzmu mogu se dobiti transformacijom iz LA. Omega-6 masne kiseline pomažu kod promena raspoloženja žena u PMS-u, smanjuju depresivna stanja, i mogu dobro delovati kod opekotina, pogotovo direktnim nanošenjem na kožu. Odnos omega-3 i omega-6 jeste 1:1, mada to u svakodnevnom životu i nije baš tako. Puno više unosimo omega-6 u vidu biljnog preradjenog ulja, a jako malo unosimo omega-3 masnih kiselina, pa ovaj odnos više počinje da liči na 20:1. probajte da smanjite unos biljnih ulja, a da povećate unos ribe i videćete sami promene.
