Dietary interventions, such as caloric restriction and a Mediterranean-style diet, reduce arterial stiffness and pulse wave velocity in overweight and obese patients.
Do dietary interventions improve arterial stiffness in overweight and obese subjects?
Dietary modifications, particularly caloric restriction and a Mediterranean-style diet, are effective strategies for reducing arterial stiffness and mitigating early cardiovascular risk in overweight and obese individuals.
Arterial stiffness is often increased in overweight/obese subjects before the development of hypertension. It is also one of the earliest indicators of increased cardiovascular disease risk and can be considered a good predictor of the development of subclinical cardiovascular dysfunction. Arterial stiffness is a significant prognostic factor influencing cardiovascular risk, which dietary habits can modify. Obese patients should use the caloric-restricted diet because it augments aortic distensibility, diminishes pulse wave velocity (PWV), and increases the activity of endothelial nitric oxide synthases. High intake of saturated fatty acids (SFA), trans fats, and cholesterol, typical for the Western diet, impairs endothelial function and raises brachial-ankle PWV. The replacement of SFA with monounsaturated (MUFA) or polyunsaturated fatty acids (PUFA) derived from seafood and plants diminishes the risk of arterial stiffness. The dairy product intake (excluding butter) decreases PWV in the general population. The high-sucrose diet causes toxic hyperglycemia and increases arterial stiffness. Complex carbohydrates with a low glycemic index (including isomaltose) should be recommended to keep vascular health. The high sodium intake (>10 g/day), particularly associated with low potassium consumption, has a deleterious effect on arterial stiffness (↑ baPWV). Since vegetables and fruits are good sources of vitamins and phytochemicals, they should be recommended in patients with high PWV. Thus, the dietary recommendation to prevent arterial stiffness should be similar to the Mediterranean diet, which is rich in dairy products, plant oils, and fish, with a minimal red meat intake and five servings of fruits and vegetables daily.
Stanek et al. (Thu,) conducted a review in Overweight and obesity with arterial stiffness. Dietary interventions was evaluated on Arterial stiffness. Dietary interventions, such as caloric restriction and a Mediterranean-style diet, reduce arterial stiffness and pulse wave velocity in overweight and obese patients.
