New Delhi, Jun 28: A daily dose of leafy greens like spinach, kale, and broccoli could significantly reduce the risk of heart attacks and strokes in older women, according to new research by Australian and Danish scientists.

The study, led by Edith Cowan University in collaboration with the University of Western Australia and the Danish Cancer Institute, highlights the role of Vitamin K1 — found abundantly in leafy and cruciferous vegetables — in preventing atherosclerotic vascular diseases (ASVDs), a major subgroup of cardiovascular disease.

ASVD, responsible for much of the world’s heart attack and stroke burden, stems from plaque buildup in arteries. The researchers found that elderly women who consumed higher levels of Vitamin K1 had a markedly lower risk of developing this condition.

The study tracked 1,436 women and found that those with around 30% higher dietary intake of Vitamin K1 had notably lower risk of ASVD. Additionally, greater Vitamin K1 intake was linked to reduced thickening of neck blood vessels — a key marker of atherosclerosis.

“Vitamin K1 may help prevent the calcification of arteries, a hallmark of cardiovascular disease,” said Montana Dupuy from ECU. “The best part? These vegetables can be effortlessly added to daily meals.”

Dr. Marc Sim, Senior Research Fellow at ECU, added that just a cup and a half of leafy greens could significantly boost daily vitamin K intake, offering an easy preventive measure for heart health.

The team is now working on developing vitamin K1-rich food products tailored for aged care communities and those with special dietary needs, aiming to translate this nutritional insight into accessible, heart-friendly meals.
