Study finds vitamin K benefits heart health


The findings of the examine had been revealed within the ‘Journal of the American Coronary heart Affiliation’.
Researchers examined information from greater than 50,000 individuals collaborating within the Danish Weight loss plan, Most cancers, and Well being examine over a 23-year interval.
They investigated whether or not individuals who ate extra meals containing vitamin Ok had a decrease threat of cardiovascular disease-related to atherosclerosis (plaque build-up within the arteries).
There are two varieties of vitamin Ok present in meals we eat: vitamin K1 comes primarily from inexperienced leafy greens and vegetable oils whereas vitamin K2 is present in meat, eggs and fermented meals akin to cheese.
The examine discovered that individuals with the best intakes of vitamin K1 had been 21 per cent much less more likely to be hospitalised with heart problems associated to atherosclerosis.
For vitamin K2, the danger of being hospitalised was 14 per cent decrease.
This decrease threat was seen for all sorts of coronary heart illness associated to atherosclerosis, notably for peripheral artery illness at 34 per cent.
ECU researcher and senior creator on the examine Dr Nicola Bondonno stated the findings steered that consuming extra vitamin Ok could also be necessary for cover towards atherosclerosis and subsequent heart problems.
“Present dietary pointers for the consumption of vitamin Ok are typically solely based mostly on the quantity of vitamin K1 an individual ought to devour to make sure that their blood can coagulate,” Dr Bondonno stated.
“Nonetheless, there may be rising proof that intakes of vitamin Ok above the present pointers can afford additional safety towards the event of different ailments, akin to atherosclerosis,” Dr Bondonno added.
“Though extra analysis is required to totally perceive the method, we consider that vitamin Ok works by defending towards the calcium build-up within the main arteries of the physique resulting in vascular calcification,” Dr Bondonno defined.
College of Western Australia researcher Dr Jamie Bellinge, the primary creator on the examine, stated the position of vitamin Ok in cardiovascular well being and notably in vascular calcification is an space of analysis providing promising hope for the long run.
“Heart problems stays a number one reason behind dying in Australia and there is nonetheless a restricted understanding of the significance of various nutritional vitamins present in meals and their impact on coronary heart assaults, strokes and peripheral artery illness,” Dr Bellinge stated.
“These findings make clear the doubtless necessary impact that vitamin Ok has on the killer illness and reinforces the significance of a nutritious diet in stopping it,” Dr Bellinge concluded.
Subsequent steps within the analysis
Dr Bondonno stated that whereas databases on the vitamin K1 content material of meals are very complete, there may be at present a lot much less information on the vitamin K2 content material of meals.
Moreover, there are 10 types of vitamin K2 present in our food regimen and every of those could also be absorbed and act otherwise inside our our bodies.
“The following part of the analysis will contain creating and bettering databases on the vitamin K2 content material of meals. Extra analysis into the totally different dietary sources and results of several types of vitamin K2 is a precedence,” Dr Bondonno stated.
Moreover, there’s a want for an Australian database on the vitamin Ok content material of Australian meals (e.g. vegemite and kangaroo).
To deal with this want, Dr Marc Sim, a collaborator on the examine, has simply completed creating an Australian database on the vitamin Ok content material of meals which will probably be revealed quickly.
The analysis is a part of ECU’s Institute of Diet Analysis. It was a collaboration with researchers from the College of Western Australia, Royal Perth Hospital, Herlev and Gentofte College Hospital in Denmark and the Danish Most cancers Society Analysis Centre.
The Institute for Diet Analysis was established as an ECU Strategic Analysis Institute in 2020. (ANI)
