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



American doctors have discovered that fish oil and vitamin D in the most common dietary supplements do not reduce the risk of cardiovascular diseases and cancers, according to the world's media. In higher doses, prescribed by doctors, fish oil helps people with high triglycerides and reduces the risk of death from cardiovascular disease.

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

About 10% of Americans drink fish oil additives. However, they are applied to vitamin D, although until now there has been little research on the benefits of vitamin D.

"Vitamin D users say it's useful for everyone, but in this study vitamin D did not prove to be anything," Dr. James Stein, a cardiologist at the University of Visconsin-Madison, who was not involved in the research.

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

In one study, doctors at Brigham and Vomens Hospital in Boston monitored the effect of a 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 already taking statins. Five years later, 17 percent of addicts survived an accident – heart attack, stroke, arterial occlusion requiring medical intervention, placebo-treated patients were 22 percent. This means that the addition of high-fat fish reduces the risk of cardiovascular events by 25 percent, Healthy says. However, it may have side effects such as arrhythmia.

A second study, conducted in the same hospital, with lower daily doses of 1 gram of fish oil, including 26,000 healthy volunteers, showed no significant difference between the placebo group and the subjects, although the first infarctions were less.

The second team also checks the effect of vitamin D supplements. Participants of the study took 2000 international vitamin units. D3 or placebo for five years. The results show that vitamin "sun" does not affect the incidence of heart attack, stroke or cancer, although they have decreased.
