Advertising is tempting: in a capsule, the vitamins and minerals that the body needs to perform many of its essential functions. They are available in pharmacies and supermarkets, and are consumed by a wide audience, including people in good health. Now, a new study adds to the scientific debate that has been open for years on the effectiveness of these products.
The article published in the circulation magazine of the American Heart Association (AHA, for its acronym in English), concluded that the intake of multivitamins and mineral supplements n & # 39; 39; is not useful for the prevention of cardiovascular disease

In the review, they found no badociation between taking supplement s multivitamins and minerals and a decreased risk of death from cardiovascular disease.
"It has been exceptionally difficult to convince people, including nutrition researchers, to recognize that multivitamin and mineral supplements do not prevent cardiovascular disease," Kim said.
The researcher hopes that these results " around these supplements and that encourage people to use proven methods to reduce the risk of disease Cardiovascular, such as eating more fruits and vegetables, exercise and avoiding tobacco.
Controversy about the effectiveness of this type of products to prevent cardiovascular disease takes years of scientific debate and many studies
Multivitamin and mineral supplements are not effective in preventing cardiovascular disease.
"Although multivitamins and minerals taken with moderation rarely cause direct damage we urge people to protect their health c ardiac by understanding their individual risk of heart disease and stroke, "write the authors.
Among their recommendations, they said that it is important to include healthy diet, exercise, smoking cessation, control of blood pressure and unhealthy cholesterol and if necessary, medical treatment.

"To have a healthy heart and a long life, eat healthy" advises Eduardo Sánchez, AHA Medical Director for Prevention and Head of Metrology Assessment Centers and the health of the badociation, who did not participate in the study. "There is no substitute for a balanced and nutritious diet with more fruits and vegetables that limits excess calories, saturated fat, trans fat, sodium, sugar and cholesterol."
A balanced diet, rich in fruits and vegetables, accompanied by physical exercises, the best recipe for a healthy heart
According to Parag Joshi, Preventive Cardiologist at UT Southwestern Medical Center in Dallas (United States) one of the strengths of the study is that it includes clinical trials. The doctor – who did not work in the research either – considered that the results confirm those of "the best scientific evidence" that suggests that multivitamins with minerals do not prevent heart disease and stroke.
"There is no magic formula to replace a healthy diet" he stressed. People who have vitamin deficiencies, such as a lack of vitamin D, which helps regulate blood pressure, should find out what's causing the problem and not rush to take supplements to fill a nutritional gap, he said. .
