What protective effect do multivitamin preparations and minerals have?
Many people today take so-called nutritional supplements. However, there are always discussions among experts about the effectiveness of these funds. Researchers have now found that multivitamin supplements and minerals have no use in preventing heart attacks, strokes, or cardiovascular diseases.
The University of Alabama scientists found in their current investigation that a mix of vitamins and minerals cannot really protect against heart attacks, strokes or cardiovascular diseases. The doctors published the results of their study in the English-language journal Circulation: Cardiovascular Quality and Outcomes.
Prevent food supplements from death from heart disease
For their investigation, the experts analyzed the data from more than two million people. The distribution of nutritional supplements enables companies to generate millions in sales. These supplements are often advertised through a wide range of health-promoting effects. However, when analyzing 18 previously published studies on dietary supplements, the researchers found no evidence that taking them could reduce deaths from heart disease.
Disadvantages of using food supplements
Suppliers may not be taking effective lifestyle or dietary measures and instead rely too much on supplements, doctors suspect. This could be a clear disadvantage for health.
Overall, it was extremely difficult to convince people, including nutritionists, that multivitamin and mineral supplements do not prevent cardiovascular disease, study author Dr. Joonseok Kim from the University of Alabama.
Rely on proven health protection methods
The current study results will hopefully help to reduce the widespread praise for multivitamin and mineral supplements. Experts say people need to be encouraged to use proven methods to reduce their risk of cardiovascular disease. For example, those affected should eat more fruits and vegetables and quit smoking.
How can food supplements be advertised?
So-called food supplements do not require approval in many countries for reasons of safety or effectiveness. While manufacturers may not make specific claims about the ability of their products to prevent, cure, or treat disease, this does not apply to more general health claims, the study's authors explain.
Dietary supplement users neglect other options
Of course, supplements that can harm your health are very rare. The problem, doctors say, is that people may neglect lifestyle or medical interventions with proven benefits if they consider vitamins to be an easier option.
There is no substitute for a balanced diet
For a healthy heart, pay particular attention to a healthy diet, the experts advise. There is no substitute for a balanced, nutritious diet with lots of fruits and vegetables, which limits the intake of excess calories, saturated fatty acids, trans fats, sodium, sugar and cholesterol, the doctors add.
