• A Look at Omega-3 Fatty Acids and Heart Health

  Date: 2007.10.25 | Category: Heart Tips | Response: 0

  According to research data published by the American Journal of Clinical Nutrition, individuals that include regular daily intake of Omega 3 can reduce the risk of heart attack (coronary thrombosis) by up to seventy percent. Such encouraging news has generated a good deal of interest in Omega 3 of late.

  What is Omega 3?

  Omega 3 is, in fact, a polyunsaturated fatty acid which, as it passes through the limentary canal (digestive tract through the human body), breaks down existing cholesterol and deposits a minutely thin barrier to prevent its reformation. Omega 3 works to fight again the principal cholesterol culprit that causes clotting of the blood. These clots then block blood vessels causing heart attacks or, if they reach the brain, strokes.

  Omega 3 is most commonly associated with the oils found in fish. Best known sources are mackerel, trout and salmon although the oils can be extracted from white fish; and the liver of the Cod is particularly rich as well.

  The American Heart Association recommends a daily intake of 1000 mg. of Omega-3 for measurable health benefits in cardiovascular care. There are various ways of including Omega 3s in your diet so you need not worry if you are not a big fan of fish.

  Sources of Omega-3s

  The most obvious method, eating suitable fish regularly, isnt practical for everybody, as again not everyone enjoys fish, some people are even allergic to it and, of course, vegetarians and vegans dont eat fish. Fortunately there are a wide range of supplements on the market for those people.

  The most common form of supplement is the capsule formulated from concentrated oils derived from those fish that have the high Omega 3 levels. Generally, the tablet will contain something around fifty percent from that source (fish) with the balance made up of other sources of fatty acids.

  Omega 3 fatty acids are not restricted to fish oils – they can also be found in a number of plant extracts as well. The best source of Omega-3 is alpha-linolenic acid (ALA) which includes flaxseed (linseed) oil, rapeseed (canola) oil, chia seeds, walnuts and walnut oil, the Mediterranean plant, purslane, grass-reared meat, and dark green leafy vegetables. These items are widely found in health food stores and in natural health markets.

  The good news of Omega 3 health benefits goes global

  Omega 3s can also be found in a wide range of other foods including vegetables and processed foods; however, the levels are negligible and provide no significant health benefits. Vegetarian Omega-3 supplements are available, usually as flaxseed (linseed) oil.

  EPA and DHA Omega 3 are found almost exclusively in aquatic plants and animals. They are synthesized by phytoplankton, which are consumed by fish, mollusks and crustaceans and thus concentrated in the aquatic food chain.

  Alternative sources of Omega-3 ALA and Omega-3 EPA and DHA are being studied for viability. ALA from perilla is already available in some countries and krill, shrimp-like creatures abundant in the Antarctic Ocean, are being targeted by a Canadian company as a future Omega-3 source. Krill oil contains 25% Omega-3 EPA and DHA. Genetic modification is also being explored, with one experiment inserting genes which will produce long-chain Omega-3 polyunsaturates into existing oilseed varieties. Another uses gene transfer technology to directly convert Omega-6 polyunsaturates to their Omega-3 counterparts.

  As the health reputation of the Omega-3s grows, food manufacturers have explored the opportunity of fortifying everyday foods with Omega-3s. Omega-3 eggs are increasingly available; for example, bread fortified with 13mg of Omega-3 DHA per slice is now available in New Zealand and Australia. Malaysia has a cracker fortified with vitamins, minerals and both Omega-3 and Omega-6 EFAs and a similarly fortified margarine serves as a fine accompaniment.

  In Sweden, a low fat liver pate is enriched with Omega-3, iron and vitamins. The Spanish can buy fruit juices fortified with milk, fiber, vitamins and Omega-3, and probiotic meal replacement bars, soups and milkshakes with Omega-3s. Finns market a blackcurrant juice with added Omega-6 and Omega-3 as ALA. This list is by no means comprehensive, particularly as it does not include the increasing number of infant milks, foods and supplements with added Omega-3 DHA.

  As the advantages of regular intake of Omega 3 become more accepted in North America, the food processing and pharmaceutical industries will, no doubt, put more effort and funding into making these various supplements more readily available. The benefits of Omega 3 will continue to grow in importance as the population ages and looks for ways to maintain healthy and active lifestyles. Currently, Omega 3s are easy enough to buy from online companies and specialized pharmacies but it surely wont be long before Americans will be able to choose the supplement that suits them best from the shelves of local supermarkets and convenience stores.

• High-dose statins lower heart attack risk

  Date: 2007.04.03 | Category: Heart Tips | Response: 0

  If you suffer from stable heart disease, a higher dose of the class of cholesterol-lowering drugs known as statins might decrease the risk of heart attacks and strokes for you, a new study shows.

  The study, funded by Pfizer, and called Treating New Targets, or TNT, showed that the top dose of Atorvastatin calcium decreased the risk of heart attacks and strokes in people with stable heart disease, compared to the lowest dose of the same drug.

  “Atorvastatin calcium is a prescription medicine used with diet to lower cholesterol,” said Dr Graham Jackson, a British-based consultant cardiologist, who was in Kuala Lumpur last week. “Lowering cholesterol levels is a proven strategy in reducing the risk of heart attack and heart disease but it is not certain what the appropriate target for lowering cholesterol should be in individuals with known heart disease. This study helped determine that. The results could potentially change the standard of care for patients with CHD.”

  The five-year Treating to New Targets Trial (TNT) involved 10,000 patients with established coronary heart disease and elevated LDL, or “bad” cholesterol levels. The study assessed whether patients on high-dose Atorvastatin calcium who aggressively lowered their LDL-cholesterol levels to well below the current guidelines (100 mg/dL) would experience additional cardiovascular benefits compared to Atorvastatin calcium patients who maintained their LDL-cholesterol at recommended levels.

  Patients who received 80 ma doses of Atorvastatin calcium had 22 per cent fewer cardiovascular events, including CHD death, non-fatal heart attacks, resuscitated cardiac arrest, and fatal or non-fatal strokes compared to patients who took 10 mg of Atorvastatin calcium. In addition, patients treated with high- dose Atorvastatin calcium had 25 per cent fewer fatal or non-fatal strokes compared to those treated with just 10 mg of Atorvastatin calcium.

  Dr Sim Kui-Hian, head of both the department of Cardiology and the Clinical Research Centre at the Sarawak General Hospital, said that the average cholesterol levels of the Malaysian population have been increasing since 1961 and the majority of Malaysians with elevated cholesterol are not at their recommended goal levels.

  “This is despite the fact that coronary heart disease is the leading cause of death in Malaysia,” said Dr Sim.

  “Everyone hates taking medicine,” he said. “But this drug is generally well tolerated. Adverse reactions usually have been mild and transient, with the most frequent adverse effects of atorvastatin being constipation, flatulence, dyspepsia and abdominal pain.”

  “The mainstay of treatment; besides medication, is exercise, diet and maintaining a healthy body weight,” said Dr Sim. If patients are on a higher dosage of atorvastatin coupled with exercises, not smoking, maintaining correct blood pressure and controlling diabetes, coronary vascular diseases can be remarkably reduced by 80 per cent.
