BARCELONA, Spain, Jan. 17,
2025 /PRNewswire/ -- Results from a study funded by
the International Nut and Dried Fruit Council have been published
in the journal Nutrients.[1] The study showed
that longer-term consumption of mixed nuts may lower cardiovascular
disease (CVD) risk in older adults with obesity or overweight,
potentially aiding in the development of accessible dietary
interventions to improve cardiovascular health in at-risk
populations.
The newly published study builds on earlier research that showed
consuming mixed nuts over a long-term period significantly reduced
total and LDL ('bad') cholesterol levels. It aimed to provide a
more comprehensive understanding of the relationship between nut
consumption and lipoprotein-related CVD risk.
The study found that eating mixed nuts significantly improved
blood lipid levels, creating a more heart-healthy profile,
including changes in certain lipoprotein subclasses related to
better heart health. The results provide deeper insights into how
nuts can influence blood lipids.
Dr. Peter Joris and Dr.
Kevin Nijssen from Maastricht University, Netherlands, stated, "Based on these results,
we have concluded that incorporating mixed nuts into the diet may
contribute to reduce the risk of CVD in older adults."
The study was a randomized, controlled crossover trial that
analyzed the effects of the daily consumption of mixed nuts on
lipoprotein particle levels in older adults with obesity or
overweight. Twenty-eight participants completed two 16-week phases:
a control period with no nut consumption and an intervention period
where they consumed 60 grams/day of mixed nuts (15 g each of
walnuts, pistachios, cashews, and hazelnuts). The two phases were
separated by an 8-week washout period. The investigators evaluated
the effect of nut consumption on lipoprotein particle numbers,
sizes, and lipid content across various lipoprotein subclasses
using an advanced NMR metabolomics platform.
