A little sunbathing, taking vitamin D supplements and eating foods rich in the vitamin, such as eggs and red meat, can all help you survive cancer. The vitamin also protects against heart disease and diabetes and strengthens our bones.
Most of us are deficient in the vitamin, especially if we live in the northern hemisphere, and even when the sun is out, 'safe sun' health guidelines recommend we cover up or stay in the shade.
A deficiency of this vital vitamin makes us more liable to a range of diseases and doubles our chances of pancreatic cancer.
Vitamin D deficiency has been on the agenda of the American Society of Clinical Oncology's annual conference, with several research papers being presented. Michigan State University researched more than 80,000 people and discovered that taking a vitamin D supplement for three years or longer reduced deaths from all cancers by 13 per cent.
Research from Madrid University found that a daily vitamin D supplement reduced deaths from prostate cancer by 38 per cent, while researchers at Allegheny Health Network Cancer Institute concluded that a vitamin D deficiency doubles the risk for pancreatic cancer.
