Consuming dietary antioxidants, polyphenols, and omega-3 fatty acids helps protect your vascular endothelium to regulate arterial elasticity.

Cardiovascular Nutrition: Fueling Endothelial Function

Your vascular endothelium relies on a steady intake of dietary antioxidants, polyphenols, and micronutrients to regulate arterial elasticity. Emphasize colorful leafy greens, berries, legumes, and omega-3 fatty acids from wild cold-water fish or flaxseeds.

Simultaneously reduce ultra-processed foods that contain hidden sodium, refined sugars, and industrial trans fats. Excessive sodium intake accelerates arterial stiffening and drives blood pressure readings into hazardous territory.

Work with a registered dietitian nutritionist to tailor heart-healthy eating patterns to your cultural preferences and financial budget. Nourishing your body with whole foods provides the foundational substrate for stable cardiovascular health.
