Purpose of review

This network meta-analysis (NMA) compares the efficacy of dietary interventions in improving flow mediated dilation (FMD) as a measure of endothelial function among individuals with cardiovascular diseases (CVDs) and hypertension. This work can be a basis for the design of future clinical trials and for the development of evidence-based nutritional guidelines to improve cardiovascular outcomes.

Recent findings

The most substantial improvements in FMD were observed with magnesium (MD: 8.17; CoE: High), vitamin D3 (MD: 7.84; CoE: High), flaxseed (MD: 7.39; CoE: Low), barberry (MD: 6.64; CoE: Moderate), folic acid (MD: 3.36; CoE: Low), and omega-3 (MD: 1.83; CoE: Very low). Sensitivity analyses confirmed the robustness of these findings. Several dietary interventions, particularly magnesium and vitamin D₃, have been shown to improve endothelial function in individuals with CVDs and hypertension. These findings highlight the potential role of nutritional strategies as adjunct therapies for preserving vascular health.
