Johns Hopkins Health - Get Your D
Issue No. 3
Get Your DDate: January 24, 2009
Many of us have long associated vitamin D with bone-strengthening properties. But inadequate levels pose an even more lethal risk to overall health, Johns Hopkins researchers say.
In addition to increasing the risk of some cancers, vitamin D deficiencies have been tied by Johns Hopkins team members to substantially increased death due to heart disease. Those results, notes study co-investigator Erin Michos, M.D., make it clear that blood levels of vitamin D should be monitored.
Supplements are OK, but the best sources for vitamin D are brief daily exposure (10 to 15 minutes) to sunlight, fortified dairy products, and fish such as sardines and mackerel. Experts recommend 200 to 400 international units a day for adults and children.
