American doctors found that fish oil and vitamin D in the most common dietary supplements do not reduce the risk of cardiovascular disease and cancer, world media reported. In higher doses, prescribed by doctors, however, fish oil helps people with high triglycerides and reduces the risk of death of cardiovascular disease.
Professionals welcomed the results of both studies presented at a conference of the Association of American Cardiologists. They said this is the guides for a new treatment option for hundreds of thousands of patients.
About 10 percent of Americans drink fish oil supplements. Still, they turn to vitamin D, although the benefits of vitamin D. have been far researching so far.
"Vitamin D adherents claim that it is useful for everything, but in this particular study, vitamin D has proved to be nothing," said Dr James Stein, a cardiologist at the University of Wisconsin-Madison, who was not part of & # 39; r research.
Fish oil, also known as omega-3 fatty acids, can be seen in salmon, tuna and some other fish. It reduces triglycerides and reduces inflammation. There are different types of fish oil with different fatty acids.
With one study, doctors from Brigham and Womens Hospital in Boston traced the effect of 4 grams of fish oil supplement, which is only available on prescription. The study included 8,000 patients with high triglycerides and a higher risk of cardiovascular problems that are already taking statins. After five years, 17 per cent of accidentalists survived – a heart attack, a stroke, an artery content requiring medical intervention, patients treated with placebo were 22 percent. This means that the high fat addiction in fat reduces the risk of cardiovascular events by 25 percent, says Zdrave.to. However, there may be side effects such as arrhythmia.
A second study, carried out in the same hospital, with a 1 gram dose of lower fish oil, which contains 26,000 healthy volunteers, did not show significant differences between the placebo group and the study subjects, although in the first time less.
The second team also check the effect of vitamin D. additives Participants took a study of 2000 international units of vitamin. D3 or placebo respectively for five years. The results show that the "sun" vitamin does not affect the incidence of heart attacks, stroke or cancer, although the latter has decreased slightly.
