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



American doctors have found that fish oil and vitamin D in the most common dietary supplements do not reduce the risk of developing cardiovascular disease and cancer, media reported globally. At higher doses, which are prescribed by doctors, 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 Cardiology Association. They said these were guidelines for a new therapeutic option for hundreds of thousands of patients.

About 10% of Americans drink fish oil supplements. Still, resort to vitamin D, although so far little research has been done on the benefits of vitamin D.

"Supporters of vitamin D claim to be useful for everything, but in this particular study, vitamin D proved to be nothing," said Dr. James Stein, a cardiologist at the University of Wisconsin-Madison, who did not participate in the research.

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

In one study, doctors from the Brigham and Womens Hospital in Boston watched the effect of supplementing 4 grams of fish oil, available only on prescription. The study included 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 – heart attack, stroke, artery blockage requiring medical intervention, placebo-treated patients were 22%. This means that the high-fat supplement reduces the risk of cardiovascular events by 25%, says Zdrave.to. However, it may have side effects such as arrhythmia.

A second study, conducted at the same hospital, with a lower daily dose of 1 gram of fish oil involving 26,000 healthy volunteers, showed no significant differences between the placebo group and the study subjects, although the first stroke was less.

The second group also controls the effect of vitamin D supplements. Participants in the study received 2000 international units of vitamin. D3 or placebo respectively for five years. The results show that vitamin "sun" does not affect the occurrence of heart attacks, strokes or cancer, although the latter have been slightly reduced.
