Vitamin D is an essential nutrient for maintenance of calcium homeostasis. In case of vitamin D deficiency, low vitamin D production rate in skin, insufficient metabolic activation of vitamin D, reduction of bone mass, and osteoporosis would be induced. In the last year, "Dietary Reference Intakes for Japanese, 2005" was published by Ministry of Health, Labour, and Welfare, Japan. This reference was based on the concept of the dietary reference intake (DRIs). The parameter for the assessment of vitamin D nutrition status was defined on the basis of the plasma levels of 25-hydroxyvitamin D, and established as "adequate intake" in the reference. The dietary vitamin D intake for prevention of osteoporosis will be more important according to the progress of examination of dietary vitamin D intake in Japanese.
