Vitamin D, the sunshine vitamin, improves bowel cancer survival

Researchers studied 1598 patients with stage I-III colon or rectal cancers after surgery.

Nearly half of the patients had low levels of vitamin D. Low levels of vitamin D were associated with higher risk of dying of colorectal cancer.

The study was conducted in Scotland where, like Tasmania, vitamin D deficiency is common.

Even if you went outside to expose your chest or back the sun, you will not be able to make any vitamin D in the depth of a Tasmanian winter.

In fact, you problably need to run around naked all summer to generate enough stored vitamin D to see you through winter.

This study clearly showed that cancer patients are often low in vitamin D and that being low is associated with a poor outcome.

Yet, this fact is completely ignored in the conventional care of cancer patients.
