– Most young people, like students, have vitamin D deficiency status
– fasting blood glucose in the highest vitamin D group, half of the lowest group
– Analysis of 4100 students by Professor Cho, Hee-kyung of the Seoul National University

The higher the concentration of vitamin D in the blood, the lower the cholesterol and triglyceride levels and the lower the fasting blood sugar level. Vitamin D deficiencies are below 20 ng / ㎖ and vitamin deficiencies range from 20.0 to 29.9 ng /, but the average vitamin D concentration in Korean students is only 11.1. ng /.

Professor Cho, Hee-kyoung from the Seoul National University Medical College badyzed blood levels of vitamin D, cholesterol and blood sugar based on data from 4124 elderly healthy students from 18 to 39 years examined at the Seoul University from April to May 2013. The results of this study (the relationship between serum vitamin D levels and cardiovascular metabolic risk factors in Korean adolescents) were featured in the current issue of the Journal of the Korean Academy of Family Medicine.

The average blood vitamin D concentration of the students was 11.1 ng / l, which was clearly insufficient. The researchers divided the students into four categories based on their vitamin D level. The lowest grade 1 average was 7.0 ng / ml. The highest average for 4 grades was 16.5 ng / ml, still in the deficient state. This is a result of showing that young people who do not like sunburn have vitamin D deficiency or the most serious condition of all ages.

The probability of having a fasting blood glucose greater than 100 mg / l was only 0.45 times greater than that of the least advanced university students among the Grade 4 students having the highest level of vitamin D in the blood. Grade 4 students are more likely to have a total cholesterol level of 200 mg / dl or higher, a serum LDL (bad cholesterol) level above 100 mg / dl, or a blood triglyceride level greater than 150 mg / dl. 0.82 times and 0.47 times, respectively.

This means that even if the level of vitamin D in the blood is "deficient", the higher the concentration, the better is the health index of the blood vessels, such as blood glucose, blood cholesterol, LDL cholesterol and blood triglycerides.

Vitamin D deficiency not only increases the risk of osteoporosis and fracture, but has recently been badociated with the risk of cancers such as diabetes, hypertension, dyslipidemia, metabolic syndrome, cancer colon and prostate cancer.

In a previous study, researchers found that the lower the serum vitamin D level, the higher the incidence of cardiovascular events such as angina and myocardial infarction. "In a 10-year follow-up study in adults without cardiovascular disease, the risk of myocardial infarction was twice as high."
