Vitamin D could halve cancer rates - a UCSD Medical Center Article below.

The role of vitamin D in cancer prevention has already been in the news, but now researchers

are estimating the number of cancer cases that could be prevented if vitamin D levels met proposed targets.

Increased vitamin D intake could prevent as many as 50% of breast and colon cancer cases,

or some 600,000 cases per year worldwide, researchers at the University of California, San

Diego (USCD) have found.

The USCD study, which examines the relationship between blood vitamin D levels and risk

of colon and breast cancer, combines data from surveys of blood vitamin D levels during winter

from 15 countries. It's the first such study to look at sunshine and cloud cover measurements

in countries where blood levels of vitamin D3 have also been determined.

Vitamin D3 is available through diet, supplements and exposure to sunlight.

According to study projections, a 50% reduction in colon cancer incidence would require

universal intake of 2,000 international units (IU) per day of vitamin D. For an equivalent

reduction in breast cancer incidence, universal intake would need to be 3,500 IU per day.

By comparison, the median adult intake of vitamin D in the US is only 230 IU per day.

Vitamin D deficiency affects people who live in colder climates such as Canada because

sunlight induces the production of vitamin D. If blood vitamin D levels are low, researchers

recommend vitamin D supplements in combination with foods containing vitamin D and short

intervals of sun exposure.
