The study also suggests vitamin D supplements could be an effective
treatment in some cases of hypertension.
Hypertension is a risk factor for diabetes and cardiovascular diseases.
The Mendelian randomisation study used genetic data involving more than 146,500 Europeans and examined two genetic variants that influence circulating
25-hydroxyvitamin D or 25(OH)D concentrations – a method normally used to
assess vitamin D status.
The research showed for each 10% rise in 25(OH)D concentration there was a
fall in diastolic blood pressure (-0.29 mm Hg) and systolic blood pressure
(-0.37 mm Hg), and an 8.1% drop in the risks of developing hypertension.
“And I think that this is a potentially important finding, because it’s
likely that avoiding a Vitamin D deficiency, we can also lower the risk of
developing hypertension,” said study author Professor Elina Hypponen from
the University of South Australia.
Earlier studies have suggested a link between vitamin D deficiency and
development of autoimmune diseases, such as multiple sclerosis.
This is the first study to show strong links between vitamin D deficiency
People with darker skin, people who are confined to their homes
and those who belong to northern latitude countries are at higher risk of
getting vitamin D deficient.
According to Hyppo?nen, since blood tests for Vitamin D are
expensive and not regularly done, one should ensure getting sufficient vitamin
D by spending some time outdoors. He
also recommends Vitamin-D fortified foods, such as mushrooms, salmon, cod liver
oil and dairy products like milk, eggs, cheese to combat the deficiency.
He also suggests taking 400 and 1,000 international units of
vitamin D daily.
