Heart-Healthy Foods: Eating a Heart Smart Diet

Heart Healthy Foods

Heart disease, or cardiovascular disease (CVD), is the leading cause of death worldwide. The disease affects your heart and associated blood vessels. Plaque buildup along arterial walls, heart-muscle fatigue, and poor blood circulation are just a few of the health realities some CVD sufferers face daily. Before you are compelled to select cardiovascular treatments due to preventable heart disease afflictions, first opt for a heart-healthy diet to impede these danger signs from developing.

Heart-Healthy Helpers

In conjunction with an active lifestyle, regularly consuming heart-healthy foods is the best way to prevent cardiovascular disease. Foods that are good for cardiovascular health are also easy to incorporate into your daily meal plans or a heart-healthy smoothie, and they contain an onslaught of heart-healing nutrients.

  • Polyunsaturated fats:
    • Omega-3 fatty acids relieve inflammation, lower blood pressure, decrease stroke risk, and reduce triglyceride levels that, if left unchecked, predispose a body laden with extra fat cells to heart damage. Omega-3s are great for your circulatory system because they combat blood cell coagulation—a risk factor for developing stroke.
    • Omega-6 fatty acids may have anti-inflammatory effects. The American Heart Association recommends daily intake of this nutrient in moderation—5 to 6% of total calories.
  • Monounsaturated fats help to lower both sugar levels and high cholesterol levels. These fats nurture your body’s cells, while saturated fats can impede cell function.
  • Beta-glucan is a soluble fiber found in most whole grain foods. This fiber is excellent for satisfying urges to nibble between meals, and it lowers “bad” (LDL) cholesterol levels. In general, fiber helps to maintain your weight and digestive system, keeping you regular. Beta-glucan is effective at decreasing your risk of heart disease and coronary heart disease—a specific set of diseases that includes angina and heart attacks.
  • Antioxidants combat the free-radical reactions that deteriorate heart system cells. A study in the journal Coronary Artery Disease showed that these molecules are effective at preventing coronary artery disease.
  • Vitamin C is a powerful antioxidant that is essential for proper cell function overall. A study showed that vitamin C deficiencies have been linked to higher risks of cardiovascular disease development.
  • Resveratrol has formidable antioxidant properties and is found in dark-skinned grapes and berries. Resveratrol prevents platelets in the blood from clotting.
  • Selenium may protect the entire cardiovascular system. In one observational study, this antioxidant exhibited questionable effectiveness for thwarting coronary heart disease risk.
  • Procyanidins possess antioxidant qualities that help fortify arterial health by reducing cholesterol.
  • Alpha-carotene, as do many other antioxidants, exhibits potent cell-damage reversal properties in the prevention of chronic diseases like heart disease.
  • Lycopene is an essential anti-inflammatory CVD prevention nutrient. It strengthens the cardiovascular system by impeding heart disease risk factors.
  • Phytic acid is an effective nutrient for decreasing risks associated with diabetes. The journal Advances in Pharmacological Sciences published a study detailing phytic acid’s ability to reduce triglyceride levels and increase “good” (HDL) cholesterol.
  • Flavonoids promote blood flow, decrease inflammation, and prevent the blood from clotting. Isoflavones and polyphenols are included with this nutrient family.
  • Folates are B vitamins that bolster endothelium function in blood vessels, according to one study, and may be linked to decreased risk for heart disease.
  • Allicin has been shown to decrease arterial wall thickness, one study showed, thereby lowering the risk for heart disease. A 2016 study in the journal Oxidative Medicine and Cellular Longevity documented allicin’s ability to decrease the effects of hypertension.
  • Potassium, consumed at moderate levels, counters heart arrhythmia symptoms. Low potassium levels have been linked to heartbeat irregularities.
  • Calcium is excellent for keeping blood vessels healthy and controlling high blood pressure.
  • Vitamin K deficiencies foster an increased risk for coronary heart disease. Leafy green vegetables are rich with vitamin K.
