Boston (SmartAboutHealth) - Recent reports state that we’re simply not getting enough Vitamin D.

Researchers are saying that we’re spending too much time indoors and and not enough time outdoors in the sun; resulting in lower levels of vitamin D in our systems.

The data was taken from two groups; one from 2001 to 2004, which had roughly 19,000 people and the other from 1988 to 1994 which had 13,000. The study shows levels of vitamin D have dropped nearly by half when comparing the first group to the second.

Comparing the groups further, the average vitamin D levels dropped from 30 nanograms per milliliter (first group) to 24 nanograms per milliliter (second group).

Researchers say that by blocking out the sun lowers the risk of skin cancer, however raises the risk of osteoporosis and fractures, heart disease, various infections and some cancers.
