Higher sodium intake associated with increased lightheadedness in the context of the DASH-sodium trial: Study turns common knowledge on its head by challenging experts' traditional recommendations -- ScienceDaily
However, contrary to this recommendation, researchers at Beth Israel Deaconess Medical Center (BIDMC) found that higher sodium intake, when studied in the context of the DASH-Sodium trial (Dietary Approaches to Stop Hypertension), actually increases lightheadedness. These findings challenge traditional recommendations to increase sodium intake to prevent lightheadedness. The study appeared today in the Journal of Clinical Hypertension.
"Our study has real clinical and research implications," said Stephen Juraschek, MD, PhD, the study's corresponding author and a primary care physician at BIDMC. "Our results serve to caution health practitioners against recommending increased sodium intake as a universal treatment for lightheadedness. Additionally, our results demonstrate the need for additional research to understand the role of sodium, and more broadly of diet, on lightheadedness."
