Warnings about sun exposure and skin cancer risk have over-shadowed awareness about the virtual epidemic of deficiency in vitamin D, the "sunshine" vitamin, argues Carlson (history, Western Oregon U.). She presents a summary of health trends-- including the recurrence of the children's scourge of rickets of bygone eras, evidence linking a host of ailments to low sun exposure and vitamin D levels, and food sources. The book includes a glossary for general audiences. Annotation 穢2009 Book News, Inc., Portland, OR (booknews.com)
