Key result
Vegetarian diet linked to lower c-IMT vs omnivorous diet in healthy subjects.
Why the study?
Does a vegetarian diet improve carotid to femoral pulse wave velocity and carotid intima media thickness compared to an omnivorous diet in healthy subjects?
Meta-Analysis
Does a vegetarian diet improve carotid to femoral pulse wave velocity and carotid intima media thickness compared to an omnivorous diet in healthy subjects?
Mean Difference: -29.86 (95% CI -58.41–-1.32)
A vegetarian diet is associated with improved surrogate markers of arterial stiffness and atherosclerosis in healthy individuals.
May support dietary counseling in healthy adults; leaves open causality and long-term outcomes pending prospective trials.
: Our findings suggest that a vegetarian diet is associated with improved arterial stiffness and reduced atherosclerosis in healthy individuals. These results support the inclusion of a well-balanced vegetarian dietary pattern in the prevention and management of cardiovascular diseases. However, further research is needed to explore the effects of a vegetarian diet on arterial health in diverse populations and to assess long-term cardiovascular outcomes.

Saz‐Lara et al. (2024) conducted a meta-analysis in Healthy subjects. Vegetarian diet vs. Omnivorous diet was evaluated on Carotid intima media thickness (c-IMT) (MD -29.86, 95% CI -58.41, -1.32). A vegetarian diet was associated with a significantly lower carotid intima media thickness compared to an omnivorous diet in healthy subjects (mean difference -29.86).
