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


American doctors have 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. At higher doses, which are prescribed by doctors, however, fish oil helps people with high triglycerides and reduces the risk of dying from cardiovascular disease.

Professionals welcomed the results of the two studies presented at a conference of the American Cardiology Society. "These are guidelines for new treatment for hundreds of thousands of patients," he said.

About 10 percent of Americans drink fish oil supplements. However, they tend to vitamin D, although so far there has been little research on the benefits of vitamin D.

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

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

With one study, doctors from Brigham and Boston Hospital followed the effect of adding 4 grams of fish oil, which is only available in the prescription. The study included 8,000 patients with high triglyceride levels and a higher risk of cardiovascular problems already taking statins. After five years, 17% of addicts survived an accident – heart attack, stroke, artery blockage requiring medical intervention, patients receiving placebo were 22%. This means that adding high-fat fish reduces the risk of cardiovascular events by 25%, says However, it can have side effects such as arrhythmias.

A second study in the same hospital, with a daily lower 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 in the first buses there were fewer.

The second team also examines the effect of vitamin D supplements. The study participants took 2000 international vitamin units. 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 decreased slightly.
