肥胖和维生素D缺乏之间的关系似乎是一条单行线。在这两种疾病中,大量的遗传学研究发现肥胖可能降低维生素D水平,但是单一维他命缺乏的倾向不会导致肥胖。这些发现也证明提高维生素D水平不能逆转肥胖。科学家已经研究了很多年两者之间的关系,但是要确定其原因和影响是十分困难的。奥马哈Creighton大学的内分泌学家Robert Heaney说:“我认为这是对数据合理与正确的解释。我认为这是值得报道的。” The relationship between obesity and vitamin D deficiency seems to be a one-way street. In both diseases, a large number of genetic studies have found that obesity may reduce vitamin D levels, but the tendency of a single vitamin deficiency does not lead to obesity. These findings also demonstrate that increasing vitamin D levels can not reverse obesity. Scientists have studied the relationship between the two for many years, but it is very difficult to determine their causes and effects. Robert Heaney, an endocrinologist at Creighton University in Omaha, said: “I think this is a reasonable and correct interpretation of the data and I think it is worth reporting.” "
