controversy over the Institute of Medicine's new recommendations (RDA) for vitamin D and calcium

You'll hear controversy over the Institute of Medicine's new recommendations (RDA) for vitamin D and calcium. They call for MORE vitamin D and LESS calcium...but many experts say the vitamin D doses are still not high enough.

Vitamin D. The new RDA is 400 IU for infants, 600 IU for ages 1 to 70...and 800 IU for over 70. But these RDAs are based only on the amount needed to prevent rickets, osteomalacia, and fractures.

Higher amounts of vitamin D are associated with a lower risk of falls, cancer, heart disease, autoimmune disorders, etc. But the RDA is not set higher because there's not sufficient proof of these benefits.
