   * **[[home:pathogenesis:vitamind:latitude|Latitude studies]]** - The "latitude studies" are observational, as opposed to interventional, studies, which use ambient solar UV radiation as a proxy for latitude and vitamin D status. For these studies, researchers compare rates of certain major cancers - most notably breast, colorectal and prostate cancer - to rates of sunlight exposure. This group of research has the liability of being wildly inconsistent. The choice to publish research on a specific latitude gradient may be a better proxy for a researcher's bias.   * **[[home:pathogenesis:vitamind:latitude|Latitude studies]]** - The "latitude studies" are observational, as opposed to interventional, studies, which use ambient solar UV radiation as a proxy for latitude and vitamin D status.

   * **Interventional studies** - While some randomized controlled trials have suggested that consuming vitamin D reduces rates of cancer, larger and more carefully controlled studies show no such effect.    * **Interventional studies** - While some randomized controlled trials have suggested that consuming vitamin D reduces rates of cancer, larger and more carefully controlled studies show no such effect. 
-  * **Studies of vitamin D status** - Many of the studies examining the relationship between vitamin D status and incidence of cancer argue that low levels of 25-D contribute to cancer. This conclusion has been invalidated by larger well-controlled studies. Although the immune system works to downregulate 25-D (25-hydroxyvitamin D) in inflammatory diseases such as cancer, very high levels of 25-D are a clear indication of regular supplementation. These studies suggest that consuming large amounts of vitamin D predispose a person to increased incidence of cancer.+  * **Studies of vitamin D status** - Many of the studies examining the relationship between vitamin D status and incidence of cancer argue that low levels of 25-D contribute to cancer.
