Daily Orange Juice Consumption Linked to Improved Cardiovascular Health, New Research Suggests
New York, NY – september 17, 2025 – A growing body of evidence indicates that regular consumption of orange juice may contribute to significant improvements in heart health, potentially lowering cholesterol levels and reducing blood pressure. Findings from multiple studies presented this week at the American Heart AssociationS annual conference suggest a daily glass could be a simple dietary addition with substantial benefits for millions at risk of cardiovascular disease.
Cardiovascular disease remains the leading cause of death globally, accounting for approximately 17.9 million deaths annually, according to the World Health Organization. Elevated cholesterol and hypertension are key risk factors, and current preventative strategies often involve complex lifestyle changes and pharmaceutical interventions. This new research highlights orange juice – specifically its high concentration of vitamin C, flavonoids, and potassium - as a potentially accessible and palatable means of supporting heart health, offering a complementary approach to existing guidelines.
Researchers at Florida State University, analyzing data from a randomized controlled trial involving 118 participants with elevated cholesterol, observed an average reduction of 8% in total cholesterol and a 5% decrease in LDL (“bad”) cholesterol among those who consumed 500ml of orange juice daily for eight weeks, compared to a control group. Separate studies have demonstrated a correlation between flavonoid intake from citrus fruits and improved endothelial function, the ability of blood vessels to dilate properly, which is crucial for healthy blood flow.
“The benefits appear to stem from the unique combination of nutrients found in orange juice,” explained Dr. Emily Carter,lead author of the Florida state University study. “Vitamin C acts as an antioxidant, protecting against damage to blood vessels, while potassium helps regulate blood pressure. The flavonoids, particularly hesperidin, have shown promising effects on cholesterol metabolism.”
While the research is encouraging, experts caution against viewing orange juice as a standalone solution.A balanced diet, regular exercise, and maintaining a healthy weight remain paramount for cardiovascular well-being. Furthermore, the sugar content in orange juice should be considered, particularly for individuals with diabetes or those monitoring their sugar intake. The American Heart Association recommends limiting added sugars to no more than 36 grams per day for men and 25 grams per day for women. A typical 8-ounce glass of orange juice contains approximately 21 grams of sugar.
Future research will focus on identifying the optimal dosage of orange juice for cardiovascular benefits and exploring the long-term effects of daily consumption. Scientists also plan to investigate the potential synergistic effects of orange juice with other heart-healthy foods and lifestyle interventions.
