New Delhi – Regular consumption of leafy green and cruciferous vegetables such as spinach, kale, and broccoli may significantly reduce the risk of heart attack and stroke, especially among elderly women, according to a new study.
The research, conducted by scientists from Edith Cowan University (ECU), the University of Western Australia, and the Danish Cancer Institute, highlights the potential benefits of Vitamin K1, found abundantly in these vegetables, in preventing atherosclerotic vascular diseases (ASVDs).
ASVD, a subset of cardiovascular disease, is a major global health concern and a leading cause of death due to heart attacks and strokes. It involves the buildup of plaque in the arteries, leading to restricted blood flow and increased cardiovascular risk.
The study, which involved 1,436 elderly women, found that those with higher dietary intake of Vitamin K1 had a notably lower risk of developing ASVD.
Beyond cardiovascular benefits, Vitamin K1 is also believed to play a role in musculoskeletal health by supporting bone strength. The study further found that greater Vitamin K1 intake was associated with reduced thickening of the carotid arteries—a key indicator of atherosclerosis.
“Leafy green and cruciferous vegetables like spinach, kale, and broccoli contain Vitamin K1, which may help prevent vascular calcification processes that contribute to cardiovascular disease,” said Montana Dupuy, researcher at ECU.
“The great news is that these vegetables can be easily incorporated into daily meals.”
Dr. Marc Sim, Senior Research Fellow at ECU, added:
“This research found that women who consumed approximately 30 per cent more Vitamin K1 had a lower long-term risk of ASVD. A simple cup and a half of leafy greens a day could make a significant difference.”
Encouraged by these findings, the research team is now working on developing Vitamin K1-enriched foods tailored for communities with specific dietary needs, such as aged care residents.
The study offers promising evidence for the role of diet in cardiovascular prevention and paves the way for future nutritional strategies targeting vulnerable populations. (Source: IANS)
