Investigating dietary vitamin D in the Australian population

点击翻译按钮获取中文摘要

Vitamin D deficiency is a significant public health issue in Australia: almost one in four adults, and one in five adolescents, are vitamin D deficient. Although vitamin D can be obtained from sun exposure and diet, we know very little about dietary vitamin D in Australia. This project will determine how much vitamin D is in Australian foods, how much people get from their usual diets, and whether increasing vitamin D in foods would be a safe and effective way to reduce vitamin D deficiency.
