Can omega-3 help prevent heart disease?
Taking omega-3s is often thought of as an easy way to protect the heart. Researchers have now discovered that there is really little evidence of protection against heart disease from ingestion of omega-3 fatty acids.
Researchers at the University of East Anglia found that omega-3 fatty acids do not protect against heart disease. The doctors published the results of their study in the English language journal "Cochrane Database of Systematic Reviews."
Data from over 100,000 subjects badyzed
Experts reviewed several studies in which more than 100,000 people participated. Little evidence of protection against heart disease has been found. However, despite the lack of protective effects, consumption of oily fish may be recommended as part of a healthy diet, the researchers say. Most studies have focused on dietary supplements rather than on omega-3 intake of fish. The NHS advises, for example, that people should try to eat two servings of fish a week, at best some should be oily fish like salmon, fresh tuna or mackerel.
What is omega-3 fatty acids? Fatty acids 3 contain alpha-linolenic acid (ALA), which the body can not produce itself. ALA can be found in oily fish, fish oils and cod liver oil. In addition, omega-3 fatty acids also contain eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which can be produced in the body by ALA, but also in oily fish, fish oils and cod liver oil. There is also milk, yogurt, bread and spreads containing additional omega-3s. When it comes to fish oil supplements, the results may refute that omega-3 supplementation is protective for the heart, author of the Dr. Lee Hooper's study of the & a oper oper est est pour pour pour, pour,,,,,,,,,,.

Omega-3 supplementation does not benefit heart health
This extensive systematic review covered information from many thousands of people over long periods of time, but no protective effect could be observed . the doctor added. The review provides good evidence that taking long-chain omega-3 supplements is not conducive to heart health and does not reduce the risk of stroke or stroke. death. Ingesting long-chain omega-3 fatty acids has little or no effect on cardiovascular health in this survey.
Certain fish species may contain pollutants
Some fish species contain substances harmful to health. The shark, marlin and swordfish may contain small amounts of mercury and should not be consumed by pregnant women or those planning pregnancy and by all children under 16 years of age. But others should not consume more than a portion of these fish a week.
Prefer to buy fish and vegetables
Food supplements are badociated with additional costs. Therefore, people who buy the products in the hope that they reduce the risk of heart disease, rather invest their money in vegetables and fresh fish, the experts explain. (As)
