The study team compared the effect of nutrients derived from
different sources i.e. food versus supplements. The key findings included the
following:
and do not demonstrate the same
beneficial effects of nutrients derived from food sources.
"Our results support the idea that, while
supplement use contributes to an increased level of total nutrient intake,
there are beneficial associations with nutrients from foods that aren't seen
with supplements," said Zhang.
"This study also confirms
the importance of identifying the nutrient source when evaluating mortality
outcomes."
Potential study limitations, include the time duration of
the study as well as the data of dietary supplement use and dosage was self
-reported and may be inaccurate. Additionally, residual confounding factors may
have influenced the associations that were noted.
Summary
The
study findings suggest that
consuming supplements to compensate for lack of
nutrients from the diet may not be as beneficial as we think nor does it reduce the risk of all-cause death.
