Growing Evidence That Vitamin K Improves Heart Health

Vitamin K

New Edith Cowan University (ECU) research has found that people who eat a diet rich in vitamin K have up to a 34 percent lower risk of atherosclerosis-related cardiovascular disease (conditions affecting the heart or blood vessels).

New Edith Cowan University (ECU) research has found that people who eat a diet rich in vitamin K have up to a 34 percent lower risk of atherosclerosis-related cardiovascular disease (conditions affecting the heart or blood vessels).

Researchers examined data from more than 50,000 people taking part in the Danish Diet, Cancer, and Health study over a 23-year period. They investigated whether people who ate more foods containing vitamin K had a lower risk of cardiovascular disease related to atherosclerosis (plaque build-up in the arteries).

There are two types of vitamin K found in foods we eat: vitamin K1 comes primarily from green leafy vegetables and vegetable oils while vitamin K2 is found in meat, eggs, and fermented foods such as cheese.

The study found that people with the highest intakes of vitamin K1 were 21 percent less likely to be hospitalized with cardiovascular disease related to atherosclerosis.

For vitamin K2, the risk of being hospitalized was 14 percent lower.

This lower risk was seen for all types of heart disease related to atherosclerosis, particularly for peripheral artery disease at 34 percent.

ECU researcher and senior author on the study Dr. Nicola Bondonno said the findings suggest that consuming more vitamin K may be important for protection against atherosclerosis and subsequent cardiovascular disease.

“Current dietary guidelines for the consumption of vitamin K are generally only based on the amount of vitamin K1 a person should consume to ensure that their blood can coagulate,” she said.

“However, there is growing evidence that intakes of vitamin K above the current guidelines can afford further protection against the development of other diseases, such as atherosclerosis.

“Although more research is needed to fully understand the process, we believe that vitamin K works by protecting against the calcium build-up in the major arteries of the body leading to vascular calcification.”

University of Western Australia researcher Dr. Jamie Bellinge, the first author on the study, said the role of vitamin K in cardiovascular health and particularly in vascular calcification is an area of research offering promising hope for the future.

“Cardiovascular disease remains a leading cause of death in Australia and there’s still a limited understanding of the importance of different vitamins found in food and their effect on heart attacks, strokes, and peripheral artery disease,” Dr. Bellinge said.

“These findings shed light on the potentially important effect that vitamin K has on the killer disease and reinforces the importance of a healthy diet in preventing it.”

Next steps in the research

Dr. Bondonno said that while databases on the vitamin K1 content of foods are very comprehensive, there is currently much less data on the vitamin K2 content of foods. Furthermore, there are 10 forms of vitamin K2 found in our diet and each of these may be absorbed and act differently within our bodies.

“The next phase of the research will involve developing and improving databases on the vitamin K2 content of foods.

“More research into the different dietary sources and effects of different types of vitamin K2 is a priority,” Dr. Bondonno said.

Additionally, there is a need for an Australian database on the vitamin K content of Australian foods (e.g. vegemite and kangaroo).

To address this need, Dr. Marc Sim, a collaborator on the study, has just finished developing an Australian database on the vitamin K content of foods which will be published soon.

The paper ‘Vitamin K intake and atherosclerotic cardiovascular disease in the Danish Diet Cancer and Health Study’ was published in the Journal of the American Heart Association. The research is part of ECU’s Institute of Nutrition Research.

Safer carbon capture and storage

Carbon capture and storage (CCS) is a crucial technology to mitigate the environmental impact of carbon dioxide (CO2) emissions. It involves the capture of CO2 from emissions from industrial processes, or from the burning of fossil fuels in power generation, which is then stored underground in geological formations. The UK government recently selected four sites…
