Overweight People Often Lack Vitamin D


Having an overweight body is a risk to health because it can be a trigger of heart disease, diabetes and others. A new research also found that obese people more often lack vitamin D.

Vitamin D is known to be extremely important for cell health, the absorption of calcium and proper immune function. Vitamin D deficiency also can increase the risk of bone damage and trigger certain types of cancer.

According to CBC, a team of Norwegian researchers found that obese or overweight people often have trouble absorbing vitamin D.

‘Sunshine vitamin’ which was originally absorbed must be converted into a usable form, called 1.25-dihydroxyvitamin D. But a lot of fat which accumulates in the body can disrupt the process.

To know the impact of obesity on the absorption of vitamin D, the team spent six years of study on 1,464 women and 315 men, with an average age of 49 years,was overweight, and 11 percent of them are obese.

From the beginning, overall levels of vitamin D found in participants were under a healthy range. And at the end of the study, overall levels of vitamin D was found to have declined significantly.

The research team concluded that having a higher weight than normal, body fat and high BMI was associated with the less absorption of vitamin D.

Because vitamin D levels did not correlate well with levels of 1.25-dihydroxyvitamin D, then the overweight person have to check vitamin D levels and overall health.

Researchers also suggest  people who are overweight and obese to take benefit from supplements of vitamin D and get more exposed to sunlight.

The findings were published in the January issue of the Journal of Nutrition.
