Investigating dietary vitamin D in the Australian population

在澳大利亚，维生素D缺乏是一个重大的公共卫生问题：几乎四分之一的成年人和五分之一的青少年缺乏维生素D。虽然维生素D可以通过日晒和饮食获得，但我们对澳大利亚饮食中的维生素D知之甚少。该项目将确定澳大利亚食物中的维生素D含量，人们从日常饮食中获得的维生素D含量，以及增加食物中的维生素D是否是减少维生素D缺乏的安全有效的方法。

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.
