Study finds obesity can 'lead to lack of Vitamin D'

Study finds obesity can 'lead to lack of Vitamin D'

Obesity can lower vitamin D levels in the body, a study suggests.

The report, in the journal PLOS Medicine, analysed genetic data from 21 studies - a total of 42,000 people.

It found every 10% rise in body mass index (BMI) - used as an indicator of body fat - led to a 4% drop of available vitamin D in the body.

As vitamin D is stored in fatty tissue, the authors suggest the larger storage capacity in obese people may prevent it from circulating in the bloodstream.

BMI it is calculated by taking weight (in kilograms) and dividing it by height (in metres) squared. Those with a BMI of 30 or above are considered obese.
