Consuming Leafy Greens May Reduce Risk of Heart Disease, New Study Suggests
A new study suggests that consuming a cup and a half of leafy greens daily can significantly lower the risk of heart disease by enhancing vascular and bone health through Vitamin K1 intake.
Recent research highlights the potential cardiovascular benefits of incorporating leafy green vegetables into daily diets. Published in the European Journal of Nutrition, the study conducted by Edith Cowan University (ECU) in collaboration with the University of Western Australia and the Danish Cancer Institute emphasizes that just a cup and a half of leafy greens like spinach, kale, and broccoli can significantly contribute to reducing the risk of atherosclerotic vascular diseases (ASVDs), which are leading causes of death worldwide due to heart attacks and strokes.
The research underscores the role of Vitamin K1, abundant in these vegetables, in preventing vascular calcification—a key process in the development of cardiovascular disease. ECU Ph.D. student Montana Dupuy explained that Vitamin K1 helps inhibit this calcification, thereby supporting vascular health. Additionally, adequate Vitamin K intake has been linked to stronger bones, benefiting musculoskeletal health.
Dr. Marc Sim, an senior researcher from ECU, pointed out that women who consume about 30% more Vitamin K1 than the standard dietary recommendations tend to have a lower long-term risk of developing ASVD. Higher Vitamin K1 levels are also associated with thinner blood vessel walls, an indicator of reduced atherosclerosis.
The collaborative team’s ongoing work aims to develop new, nutrient-rich foods containing higher levels of Vitamin K1 suitable for populations with specific dietary needs, such as aged care residents. These efforts are part of a broader initiative to improve population health through targeted nutrition.
This research supports future clinical trials and dietary recommendations by providing solid evidence of the benefits of leafy greens in cardiovascular health. Incorporating such vegetables into daily meals is a simple yet effective strategy to promote heart health and prevent related diseases.
