It is well-known that older, heavier adults have lower blood levels of vitamin D. A new study from Tufts shows that a lack of sunshine does not seem to be responsible.The researchers analyzed information on 381 men and women age 65 or older and found no difference in sun exposure among groups based on body fat percentage. The team did find that those with the highest percentage of body fat had 20 percent lower blood levels of vitamin D.
According to Dr. Susan S. Harris, one explanation could be that vitamin D is getting trapped in fat tissue and therefore not available to the blood. It seems that heavier people may need more vitamin D, whether from the sun or supplements.
1. Vitamin D is produced by your skin in response to exposure to ultraviolet radiation from natural sunlight. And it's nearly impossible to get adequate amounts of vitamin D from your diet. Sunlight exposure is the only reliable way to generate vitamin D in your own body.
The findings of such researches mentioned in your article are rather dubious and cause confusion....
