NEW YORK (Reuters Health) – Access to minerals through supplements may not benefit the patient, but may be harmful , according to a recent study .
Dietary supplementation with vitamins or minerals may not reduce the risk of death, while excessive doses of calcium may increase the risk.
The researchers looked at more than 30,000 adults in the United States. The data included interviewing participants about their diet in the past 24 hours, as well as the supplements they had taken in the past 30 days.
These data were disaggregated with death records in the following six years. The researchers found a limited association between dietary intake and increased risk of death later.
However, there were several shortcomings in the study. It was not clear whether the participant was taking supplements for medical need or simply for convalescence, and many participants reported cancer at the beginning of the study. Which casts doubt on the results of the study.
In general, the results of this study did not affect current advice on dietary supplements and diet. Everyone is advised to follow a diet that contains plenty of vitamins and minerals without worrying about getting specific types of them through supplements.
The only exception is vitamin D, which may not be available in sufficient quantities in the diet, and the sun may be absent for long periods in some regions of the world, which requires the intake of dietary supplements with the need to pay attention to the maximum daily limit allowed.
The results of the study were recently published in Annals of Internal Medicine.
