Several nutrients can support healthy arteries by helping maintain the blood-vessel lining, reducing oxidative stress, and supporting healthy blood pressure and cholesterol levels:
Omega-3 fatty acids (EPA/DHA/ALA) โ found in fatty fish, chia, flax and walnuts.
Vitamin C โ supports collagen and the integrity of blood vessels; found in peppers, citrus, guava and broccoli.
Vitamin E โ antioxidant protection; found in almonds, sunflower seeds, avocado and nuts.
Folate (B9), B6 and B12 โ help regulate homocysteine, an amino acid associated with vascular health.
Potassium โ helps regulate blood pressure; found in beans, leafy greens, avocado, potatoes and bananas.
Magnesium โ supports normal blood-vessel function and blood pressure; found in pumpkin seeds, almonds, beans and leafy greens.
Polyphenols โ plant compounds with antioxidant and vascular-supporting
effects; abundant in berries, cocoa, herbs, vegetables and extra-virgin olive oil.
Dietary fiber โ particularly soluble fiber, which can help manage LDL cholesterol; found in oats, beans, lentils, fruits and vegetables.
The bigger picture: arteries are protected not by one nutrient but by an overall dietary pattern rich in vegetables, fruits, legumes, whole grains, nuts, seeds and fish, while limiting smoking, excess sodium, trans fats, and highly processed foods.
