Walnuts (Juglans regia) have scientific evidence supporting their use in supporting cardiovascular health, including arteriosclerosis (the thickening and hardening of arterial walls). Multiple clinical studies and meta-analyses have shown that walnut consumption can improve lipid profiles, reduce oxidative stress, and decrease inflammation, all of which are key factors in the development and progression of arteriosclerosis. Walnuts are rich in polyunsaturated fatty acids (notably alpha-linolenic acid, a plant-based omega-3), antioxidants (such as vitamin E and polyphenols), and plant sterols.

A number of randomized controlled trials have demonstrated that diets supplemented with walnuts can lower total cholesterol, LDL cholesterol, and even some markers of vascular inflammation. For example, a 2019 review published in the Journal of Nutrition summarized several studies showing that walnut-enriched diets improved endothelial function and reduced arterial stiffness. While walnuts are not a "cure" for arteriosclerosis, their regular inclusion in a balanced diet is associated with reduced risk of cardiovascular events, likely due to their effects on lipid levels, antioxidant status, and vascular health.

Therefore, the use of walnuts to support cardiovascular health and arteriosclerosis has a strong scientific basis, though they are best used as part of a broader dietary strategy rather than as a sole treatment.
