维他命D已经被一些知名的公司,广泛的运用于心血管,强健骨骼,认知系统,防癌和免疫系统的保健上,且有很好的口碑!
盐湖城 intermountain医疗中心,心脏研究所的科学家声称~有更多更可靠的证据证实心脏病和日常饮食中缺乏维生素D有关!
以前的研究已经证实~缺乏维生素D和其他相关的心脏病危险因子,如:血压,血糖控制和炎症都有关.
研究人员发现,血中维生素D含量非常低的人,77%更易死亡,45%更易患冠状动脉疾病,78%更易中风.他们也发现血中维生素D含量非常低的参与者,心脏衰竭的机会是正常者的两倍!
这项最新研究的重点在于,解决维生素D缺乏和心脏病之间的直接关系.

Researchers from Utah presented fresh evidence this week linking
vitamin D deficiency to heart disease at the American Heart Association’s (AHA) Scientific Conference in
Orlando, Florida.
Vitamin D has a good reputation even in the worthy company of
other vitamins, having been associated variously with cardiovascular health,
strong bones, cognitive health, cancer protection and immune health.
Scientists from the Heart Institute at Intermountain Medical
Center in Salt Lake City now claim to have dug up stronger evidence supporting
the cardiovascular benefits of vitamin D. They also claim to have more firmly
established the link between a lack of the vitamin in the diet and heart disease.
Observational research
For more than a year, the Intermountain Medical Center research
team followed 27,686 people who were 50 years of age or older with no prior
history of cardiovascular disease.
Theparticipants had their blood vitamin D levels
tested during routine clinical care. They were divided into three groups based
on their vitamin D levels – normal
(over 30 nanograms per milliliter), low (15-30 ng/ml), or very low (less than
15 ng/ml). The scientist then followed them to see if they developed some form
of heart disease.
Researchers found that people with very low levels of vitamin D
were 77 percent more likely to die, 45 percent more likely to develop coronary
artery disease, and 78 percent more likely to have a stroke than those with
normal levels. They also found that participants with very low levels of
vitamin D were twice as likely to suffer heart failure.

Study significance
Commenting on the significance of the results, Brent Muhlestein,
director of cardiovascular research at the Intermountain Medical Centre, said: “This was a unique study because the association between Vitamin
D deficiency and cardiovascular disease has not been well-established.”
Muhlestein went on to say the previous studies have demonstrated
links between vitamin D deficiency and risk factors related to heart disease like blood pressure, glucose control,
and inflammation.
This latest research is distinct from these studies because it
tackles the link between vitamin D and heart disease directly. And although the
study is only observational, Muhlestein said it is based on a population pool
in Utah that is well suited to the task in hand.
“For
example, because of Utah’s low use
of tobacco and alcohol, we were able to narrow the focus of the study to the
effects of Vitamin D on the cardiovascular system,” said Muhlestein.
In any case, he said the conclusions create an impetus for
further study.
“We believe the findings are important enough to now justify
randomized treatment trials of supplementation in patients with Vitamin D
deficiency to determine for sure whether it can reduce the risk of heart
disease,” added
the researcher.
