Cardiovascular nutrition emphasizes dietary approaches that promote heart health by managing blood pressure, cholesterol, and inflammation levels. Key elements include healthy fats from sources like olive oil, omega-3 fatty acids from fatty fish, and a variety of fruits and vegetables rich in antioxidants. The Mediterranean and DASH diets, both well-researched for their cardiovascular benefits, incorporate these elements to reduce heart disease risk. Research in this field explores the protective effects of fiber, magnesium, and potassium on heart health, and the role of bioactive compounds like polyphenols found in berries and dark chocolate. Additionally, studies highlight the importance of limiting sodium, added sugars, and saturated fats to maintain cardiovascular health. Cardiovascular nutrition research seeks to establish evidence-based guidelines that help reduce the incidence of heart disease through dietary choices and support a long, heart-healthy life.
