High vitamin D levels linked to lower risk of colon cancer
January 21, 2010
High blood levels of vitamin D are associated with a lower risk of colon cancer, finds a large European study published on bmj.com today. The risk was cut by as much as 40% in people with the highest levels compared with those in the lowest.

However, some recent publications have suggested maintenance of blood vitamin D levels at 50 nmol/l or higher for colorectal cancer prevention. Thus, the authors also compared low and high levels of blood vitamin D concentration to a mid-level of 50-75 nmol/l. This comparison showed that while levels below the mid-level were associated with increased risk, those above 75 nmol/l were not associated with any additional reduction in colon cancer risk compared to the mid-level.

Korkeat, yli 75 nmol/l tasot eivät tuoneet lisäetua keskitasoihin 50-75 nmol/l verrattuna.
Lisää tutkimusta tarvitaan.
Their findings are based on the European Prospective Investigation into Cancer Study (EPIC), a study of over 520,000 subjects from 10 Western European countries.
