The role of dietary supplements in heart diseases treatment is still unclear. A study, published in Annals of Internal Medicine discusses this in detail. It checks the effect of these supplements on heart diseases and death.
Effect of dietary supplements on the health of a person
The term “dietary supplement” describes the products that a person eats or drinks to stay healthy. These products are neither food nor medicines.
Minerals, vitamins, herbs, and some extracts come under this category. These substances are also present in the form of a mixture.
The research team has analyzed the results of 277 clinical trials. The outcomes of these trials have shown that dietary supplements have no role in heart diseases treatment.
The research reveals that almost all herbs, minerals, vitamins, and nutrient diets are not harmful to a person. But still, their intake cannot prevent CVDs or lead to a longer life.
The study shows that among supplements, most of the health benefits are due to intake of omega 3 fatty acids and folic acid. The low salt diet also provides a few benefits.
On the other hand, a combination of calcium and vitamin D can enhance the risk of stroke. CDC surveys indicate that about 52% of American adults are taking a vitamin or any other supplement daily.
As a whole, each year, the American nation spends $31 billion on buying these products. A growing number of studies, including this one, has failed to prove the benefits of these dietary supplements.
The growing data from the research shows that most of the healthy adults don’t take any dietary supplements. Keeping this fact in mind, a person should opt for a heart-healthy diet instead of these supplements.
Influence of dietary supplements on heart diseases and survival rate
In this study, the research team has assessed 16 vitamins, 8 diets, and some other supplements. It includes Ca, Fe, Se, vitamin A, B3, B6, D, E, B9, carotene, and a low salt diet.
The study has analyzed the effects of these vitamins and diets on stroke, CHD, heart attack, and death of a person. Later, the research team ranked these supplements based on very low, low, moderate, and high-risk impact.
Calcium, iron, vitamin A, B6, C, E, D, and selenium have shown no effect on the risk of heart diseases, and death. On the other hand, a low salt diet in people with high BP had a moderate impact.
A low salt diet has specified a decrease in the risk of heart diseases by 33% and deaths by 10%. Further analysis revealed that folic acid led to a 20% reduction in the risk of stroke.
The research team has also found that the risk reduction in stroke was more in China. As in China, there was no fortification of cereals with folic acid. It suggested that the protective effects of folic acid aren’t much evident in people having a diet with enough folic acid.
The persons having omega 3 fatty acids have shown a reduction in risk of heart attack by 8% and that of CHD by 7%. On the contrary, there was a 17% increase in the risk of stroke, after using a combination of calcium with vitamin D. The research team has ranked this combination as moderate risk.
Overall results of this study indicate that a few interventions have a little effect on survival and heart health. But, a majority of dietary supplements play no role in heart diseases treatment and preventing death.
