Ultimate Guide to Omega- 3 Benefits, Sources and Supplements. By Dr. Mercola. Time and again, I have emphasized that omega- 3 fats are essential to your overall health. And I am not alone – other health experts stress the same, and decades of research have been devoted to discovering the many health benefits of omega- 3. Fish Oils supplements, health benefits, side effects, omega-3 epa and dha Use for depression, heart disease, vision and eyesight, menopause, weight loss, blood. Omega- 3 comes from both animal and plant sources. The primary animal sources are krill oil and fish oil. The primary plant sources are flaxseed, chia and hemp. They have become a multibillion- dollar business, with Americans spending about 2. Types of Omega- 3 Fats. Marine animals such as fish and krill provide eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are mostly promoted for their protective effects on your heart. Flaxseed, chia, hemp, and a few other foods, on the other hand, offer alpha- linoleic acid (ALA). You would want to choose an animal- based variety – most of the cellular health benefits linked to omega- 3 fats are linked to the animal- based EPA and DHA, not the plant- based ALA. Furthermore, ALA is converted into EPA and DHA in your body at a very low ratio. What this means is that even if you consume large amounts of ALA, your body can only convert a relatively small amount into EPA and DHA, and only when there are sufficient enzymes. Remember, though, that plant- based omega- 3 fats are NOT inherently harmful or should be avoided. Ideally, what you want to do is include an animal- based form in your diet. For instance, you can combine flax and hemp in your diet with animal- based omega- 3s. A Rundown of Omega- 3 Benefits Omega- 3 ranks among the most important essential nutrients out there today. In 2. 00. 8, the American Journal of Clinical Nutrition. EPA and DHA omega- 3 fatty acids in elderly populations. Low concentrations of EPA and DHA resulted in an increased risk of death from all causes, as well as accelerated cognitive decline. The studies also suggest that a higher intake of omega- 3s may bring certain health benefits that short- term supplementation cannot give. Here are other evidence of omega- 3 benefits: 1. Omega- 3 benefits your heart health. An Italian study (GISSI)5 of 1. Fish oils come from fatty fish, also known as oily fish; specifically the tissue of fish such as trout, mackerel, tuna, herring, sardines, and salmon. The fillets of. The fatty acid oxidation page describes the mobilization and oxidation of fatty acids and the generation and utilization of the ketone bodies. Original Article. Treatment of Diversion Colitis with Short-Chain-Fatty Acid Irrigation. Harig, M.D., M.S., Konrad H. Soergel, M.D., Richard A. Komorowski, M. The Power of Together. Welcome to Nutricia Learning Center (NLC), a community hub and trusted, collective resource for health care providers managing patients with. In a separate study, 6 American medical researchers reported that men who consumed fish once or more every week had a 5. Omega- 3 normalizes and regulates your cholesterol triglyceride levels. Compared to a statin, both fish oil and krill oil are more efficient in doing this. According to a study comparing the efficiency of krill and fish oils in reducing triglyceride levels,7 both oils notably reduced the enzyme activity that causes the liver to metabolize fat, but krill had a more pronounced effects, reducing liver triglycerides significantly more. Fasting triglyceride levels are a powerful indication of your ability to have healthy lipid profiles, which can be indicative of your heart health. Studies have also shown that omega- 3 fats are anti- arrhythmic (preventing or counteracting cardiac arrhythmia), anti- thrombotic (prevents thrombosis or a blood clot within a blood vessel), anti- atherosclerotic (preventing fatty deposits and fibrosis of the inner layer of your arteries), and anti- inflammatory (counteracting inflammation – the heat, pain, swelling, etc). DHA affects your child's learning and behavior. Do you want to maximize your child's intellectual potential? A study published in Plos One in June 2. DHA with poorer reading, and memory and behavioral problems in healthy school- age children. In another study published in the American Journal of Clinical Nutrition in August 2. Previous research also found that children with attention deficit hyperactivity disorder (ADHD) and related behavior or learning disabilities are more likely to have low omega- 3 fat levels. Omega- 3 has such great impact on your brain health – EPA and DHA keep the dopamine levels in your brain high, increase neuronal growth in the frontal cortex of your brain, and increase cerebral circulation. Omega- 3 has been found to save the lives of children going through short bowel syndrome (SBS). Omega- 3 has been found to save the lives of children going through short bowel syndrome (SBS), which is uncommon but impacts thousands of people in the United States. SBS can occur from birth (when a portion of the intestine fails to develop) or due to an infectious inflammatory disease striking premature newborns. In adults, it can be caused by surgery for Crohn's disease or injury. Alarmed by the situation, Dr. Mark Puder, surgeon at Children's Hospital Boston,1. SBS were going to die. Then the physicians noted that when the kids were given the nutritional supplement Omegaven (made of fish oil), they began to improve drastically. The fish oil treatment was given to 1. SBS are still alive. There has been striking results that the fish oil supplement is also made available at 7. Omega- 3 benefits cover many areas of health, from mental and behavioral health to preventing premature death from disease, including the following: . This deficiency can cause or contribute to serious mental and physical health problems, and may be a significant underlying factor of up to 9. In fact, dietary fat intake has been among the most widely studied dietary risk factors for breast and prostate cancers. Two studies from 2. BRCA1 (breast cancer gene 1) and BRCA2 (breast cancer gene 2) are two tumor suppressor genes that, when functioning normally, help repair DNA damage, a process that also prevents tumor development. Omega- 3 and omega- 6 fats have been found to influence these two genes – omega- 3 tends to reduce cancer cell growth, while highly processed and toxic omega- 6 has been found to cause cancer growth. Considering that omega- 3 deficiency is a common underlying factor for cancer and heart disease, it is no longer surprising for statistics to show that this deficiency may be responsible for nearly 1. A 1. 99. 1 study at the Mayo Clinic focused on 1. Another study compared Inuit (Eskimo) women to Canadian women, and it revealed omega- 3 deficiency in the milk of the Canadian nursing moms. Animal cells cannot form omega- 3, so a fetus must obtain all of its omega- 3 fatty acids from its mother's diet. A mother's dietary intake and plasma concentrations of DHA directly influence the DHA level of the developing fetus, impacting the child's brain and eye health. So remember that if you are pregnant, your baby is dependent on the omega- 3 from your diet via breast milk. It is then crucial that you maintain adequate omega- 3 supply. However, the typical American consumes far too many omega- 6 fats in her diet while consuming very low omega- 3 levels. The ideal ratio of omega- 6 to omega- 3 fats is 1: 1. Today, however, our ratio averages from 2. In fact, mainstream media has finally reported that lack of omega- 3 is among the most serious and pressing health issues plaguing our world. Omega- 6 is primarily sourced from corn, soy, canola, safflower, and sunflower oils. These are overabundant in the typical diet, which accounts for excess omega- 6 levels. Omega- 6 fats predominate the diet in the US, and this encourages the production of inflammation in your body. Many scientists believe that one reason there is a high incidence of heart disease, hypertension, diabetes, obesity, premature aging, and some cancer forms today is this profound omega- 3- omega- 6 imbalance. Sources of Animal- Based Omega- 3 Fats. Perhaps you are wondering what animal- based omega- 3 options are available for you. Here are the primary ones: . Unfortunately, the vast majority of the fish supply is now heavily tainted with industrial toxins and pollutants, such as heavy metals which include mercury, lead, arsenic, and cadmium, PCBs, and radioactive poisons. These toxins make eating fish no longer recommended. About the only exception are wild- caught Alaskan salmon and very small fish like sardines. The highest concentrations of mercury are found in large carnivorous fish like tuna, sea bass, and marlin. You may need to be especially cautious of canned tuna as well, as independent testing by the Mercury Policy Project found that the average mercury concentration in canned tuna is far over the . It is also important that you avoid farmed salmon, which contains only about half of the omega- 3 levels of wild salmon. It may also harbor a range of contaminants, including environmental toxins, synthetic astaxanthin, and harmful metabolic byproducts and agrichemical residues of GMO corn- and soy- based feed they are given. High- quality fish oils can certainly provide many health benefits. However, this oil is weak in antioxidants. This means that as you increase your omega- 3 intake through fish oil consumption, you actually increase your need for added antioxidant protection. This happens because fish oil is a bit perishable, and oxidation leads to the formation of harmful free radicals. Antioxidants and other protections are therefore necessary to ensure that the fish oil doesn't oxidize and become rancid in your body. Krill oil not only contains the important and necessary DHA and EPA omega- 3 fatty acids, but they are bound to phospholipids (see a discussion on this later). Additionally, krill oil's antioxidant potency is 4. It also contains astaxanthin, a marine- source flavonoid that creates a special bond with the EPA and DHA to allow direct metabolism of the antioxidants, making them more bioavailable. Krill – or . Krill harvesting can be completely sustainable and one of the most eco- friendly on the planet (look for products with sustainability and harvesting management certifications). Krill are the largest biomass in the world and can be found in all oceans. Antarctic krill, by far the most abundant, is under the management of an international organization of 2. Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Antarctic krill biomass is using strict international precautionary catch limit regulations, reviewed regularly to assure sustainability.
