A new study reveals that people are at risk of developing diabetes among people with vitamin D deficiency
Researchers at the University of California San Diego School of Medicine and Seoul National University conducted the study and published the results in the journal Plos One, according to The Next Observer.
The study involved 903 healthy adults, with an average age of 74, whose outpatient visits between 1997 and 1999 did not reveal risk factors for diabetes and were followed up during 2009. Doctors measured vitamin D levels in their blood during these visits, as well as blood glucose levels before and after eating.
Over time, 47 people had diabetes and 337 people had pre-diabetes symptoms, who had higher glucose levels than normal but lower than type 2 diabetes.
The researchers found that the lowest acceptable level of vitamin D in the blood is 30 ng/ml. This is 10 nanograms/milliliters higher than the level announced by the Institute of Medicine in 2010, which is now part of the National Academies, a federal government advisory medical group. But other institutions have said that the level of vitamin D should be 50 ng/ml, and the debate is still going on.
Su K said. Park, lead author of the study and professor in the Department of Preventive Medicine at Seoul National University Medical School in South Korea « We found that participants with a vitamin D level higher than 30 ng/ml reduce their risk of diabetes to one third, and those with a vitamin D level higher than 50 ng/ Milliliters reduce their risk of diabetes to one fifth.”
Cedric F. Garland, co-author of the study and associate professor in the Department of Family Medicine and Public Health at the University of California San Diego School of Medicine, found that people with a vitamin D level of less than 30 ng/ml are considered vitamin D deficient. They have five times the risk to people with a vitamin D level of more than 50 ng/ml.
Garland, who has previously studied the relationship between vitamin D level and various cancers, said the study relied on numerous research that linked vitamin D deficiency to an increased risk of diabetes. These studies analyse the distribution and incidence of diseases. But it does not prove causality.
“We need more research to study the role of high vitamin D in preventing type 2 diabetes or preventing the condition from transitioning from pre-diabetes to actual infection,” Garland said. But this study and previous research indicate a strong relationship between them.”
Garland and other scientists have long defended the health benefits of vitamin D. Garland and his brother Frank, an epidemiologist, published a study in 1980 that said that vitamin D , which the body produces after exposure to sunlight, and calcium “absorbed by the body with the help of vitamin D” reduce the risk Colon cancer. With the help of their colleagues, they also discovered the same relationship with breast, lung and bladder cancers.
Garland said that reaching the level of vitamin D in the blood to 30 ng/ml requires eating foods containing 3,000 to 5,000 IU per day, as well as appropriate exposure to sunlight “for 10 to 15 minutes at noon.”
It is currently recommended to take 400 units of vitamin D per day for children under one year of age, 600 IU per day from one to 60 years of age, and 800 IU daily after the age of 70. The level of vitamin D in the blood should not exceed 125 ng/ml because it leads to side effects such as nausea, bloating, weight loss, arrhythmia and kidney damage.
