. . and why is it so talked about ?
Research from Queen Mary, University of London suggests that omega-3 fatty acids, which are found in fish oil, have the potential to protect nerves from injury and help them to regenerate. When nerves are damaged because of an accident or injury, patients experience pain, weakness and muscle paralysis which can leave them disabled, and recovery rates are poor.
The new study, published this week in the Journal of Neuroscience, suggests that omega-3 fatty acids could play a significant role in speeding recovery from nerve injury. The study focused on peripheral nerve cells. Peripheral nerves are the nerves which transmit signals between the brain and spinal cord, and the rest of the body. These nerves have the ability to regenerate but, despite advances in surgical techniques, patients usually only have good recovery when their injury is minor.
Omega-3 fatty acids are vital for the body's normal growth and development and have been widely researched for their health benefits. Because the body cannot manufacture omega-3 fatty acids, they have to be consumed in foods such as oily fish. In the new study, researchers first looked at isolated mouse nerve cells.
They simulated the type of damage caused by accident or injury, by either stretching the cells or starving them of oxygen. Both types of damage killed a significant number of nerve cells but enrichment with omega-3 fatty acids in cells gave them significant protection and decreased cell death. The research was carried out by a group led by Adina Michael-Titus, Professor of Neuroscience at Barts and The London Medical School and lead of the Neurotrauma and Neurodegeneration group in the Centre for Neuroscience and Trauma, Queen Mary, University of London.
She explained: "Our previous research has shown that these fatty acids could have beneficial effects in a number of neurological conditions. This new study suggests that they could also have a role in treating peripheral nerve injuries. More work is needed but our research indicates that omega-3 fatty acids can protect damaged nerve cells, which is a critical first step in a successful neurological recovery.
EPA, DHA and ALA:
EPA and DHA are two of the most important omega-3 fatty acids. And both EPA and DHA are key nutrients, which means that your body needs them for normal function but cannot produce them very effiicently. The best way to get these nutrients is to increase your fish consumption or take omega-3 supplements. Omega-3 fatty acids are the building blocks of every living cell in the human body. They are absolutely necessary for normal health and development. Without them, cells can't function, renew, or maintain themselves properly. Omega 3s promote cardiovascular health, support a healthy memory and learning, help brain and vision development of infants, and promote natural joint flexibility and mobility.
DHA research
Your ability to think, learn, and remember can be influenced by the amount of DHA in your cells. Increased DHA fuels production of serotonin, the "feel-good" neurotransmitter, and can help support normal brain function. During pregnancy, DHA plays a key role in the normal development of the baby's brain and eyes. Breast milk also contains DHA, which is believed to be a factor associated with infant brain development. Scientific studies have also found that low levels of DHA have been associated with reduced brain function and are linked to a number of mood problems.
EPA (Eicosapentaenoic acid)
EPA helps in the synthesis of hormone-like substances called prostaglandins, with benefits for cardiovascular and joint health. Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease. EPA also plays a role in supporting the natural movement of joints. Your body uses omega-3 fatty acids, vitamins, and minerals to form the outer walls of every cell. This healthy cell structure helps maintain normal metabolic functions. And since your body cannot produce EPA or synthesize it from food, you need to add it to your diet or take EPA supplements.
ALA (Alpha-linolenic acid)
ALA is a short chain fatty acid. It is found in small amounts in animal flesh, in very small amounts in a variety of plant products, and in relatively large amounts in soy, walnuts, canola oil, flaxseeds and their oils, hempseed oil, camelina oil, and chia seed oil. The human body cannot make its own ALA - it must be obtained through diet. ALA omega 3s are good for your cells and your skin. Your body also converts ALA to small amounts of EPA, another omega 3 that supports cardio-vascular health.
Omega-3 FAQs:
Is the source of the omega-3 fatty acids used in WELLSON Brain Health Omega safe and sustainable?
Yes. Oils from calamari, which tend to be naturally higher in DHA, are used. The Natural Resources Defense Council lists calamari as one of the types of seafood with the lowest levels of mercury, considered safe to consume with no restrictions. Friend of the SeaŽ, an organization that recognizes sustainable marine business practices, has certified calamari as an eco-preferred source for omega 3s.
Do I still have to eat fish if I am taking a NUTRILITEŽ omega-3 supplement?
It is always a good idea to eat whole foods rich in omega-3 fatty acids, and ocean fish is the best source. But if you don't eat ocean fish at least twice a week, NUTRILITE omega-3 supplements can help you get the EPA and DHA that might be missing from your diet.
I take a multivitamin every day. Do I need an omega-3 supplement as well?
Most multivitamins do not contain any omega-3 fatty acids. If your multi doesn't include omega 3s and you aren't eating a lot of fish weekly, you should consider adding an omega-3 supplement to your diet.
How do I know the oil in NUTRILITE products is free from PCBs or other contaminants that might be in the oceans?
Because NUTRILITE scientists voluntarily joined with 23 other international companies, under the guidance of the Council for Responsible Nutrition, to work on developing standards for ensuring a supply of consistent, high-quality, raw materials. Applying those standards, we start with high-quality fish oils from ocean fish like anchovy, mackerel, and sardines. We use a proprietary process to extract the omega 3s and purify them. Finally, we test the refined oil for purity and stability.
Are there any adverse drug interactions with omega 3s?
Omega 3s from fish oil (like those in BRAINIUMSŽ DHA) have been shown to be safe if your total dietary daily intake, including food, does not exceed three grams. Daily intake of omega-3 dietary supplements should not exceed two grams. Generally speaking, if you have no difficulties eating ocean fish, supplementation with omega 3 from fish oil should present no adverse effects at levels of two grams or less. Certain medications may interact with omega-3 fatty acids. These drug interactions include aspirin, anti-coagulants, Warfarin (coumadin), and other medications that alter blood coagulation. If you are taking any of these medications, please consult your physician before adding an omega-3 supplement to your diet. It is always important to tell your pharmacist or health care professional that you are taking any supplement, including those made from concentrated fish oil.You should also contact your health care provider - especially for children under 12 years of age, pregnant or nursing women, or anyone with a medical condition.
