Myths about the effect of fish oil and vitamin D are discarded!


American physicians have found that fish oil and vitamin D in the most common dietary supplements do not reduce the risk of cardiovascular disease and cancer, the world media reported. At higher doses, which are prescribed by doctors, however, fish oil helps people with high triglycerides and reduces the risk of death from cardiovascular disease.

Professionals welcomed the results of the two studies presented at a conference of the American Cardiologists Association. They said these are guidelines for a new treatment option for hundreds of thousands of patients.

Approximately 10% of Americans consume fish oil supplements. However, they use vitamin D, although so far there has been little research into the benefits of vitamin D.

"Vitamin D adherents claim it's useful for everything, but in this particular study, vitamin D turned out to be nothing," said Dr. James Stein, a cardiologist at the University of Wisconsin-Madison, who was not involved in the research.

Fish oil, also known as omega-3 fatty acids, is found in salmon, tuna and other fish. Reduces triglycerides and reduces inflammation. There are different types of fish oil with different predominant fatty acids.

With a study, Doctors at Brigham and Womens Hospital in Boston watched the effect of the supplement of 4 grams of fish oil, available only on prescription. The study involved 8,000 patients with high triglycerides and a higher risk of cardiovascular problems already taking statins. After five years, 17% of survivors survived an accident – a heart attack, stroke, arterial occlusion requiring medical intervention, patients treated with placebo were 22%. This means that the high fat fish supplement reduces the risk of cardiovascular events by 25%, says However, they may have side effects such as arrhythmia.

A second study, conducted at the same hospital with a daily dose of less than 1 gram of fish oil, involving 26,000 healthy volunteers, did not show significant differences between the placebo group and study subjects, although the first infarcts were smaller.

The second team also checks the effect of vitamin D supplements. Study participants have taken 2000 international units of vitamin. D3 or placebo respectively for five years. The results show that vitamin "sun" does not affect the incidence of heart attacks, strokes or cancer, although they have decreased slightly.
