Multivitamines tegen darmkanker.*

Het langdurig gebruik van multivitamines geeft 30% minder kans op het ontstaan van darmkanker blijkt uit een onderzoek over 15 jaar onder 145.000 ouderen.

A study published in the American Journal of Epidemiology  concerning the benefits of vitamins for colon/rectal cancer. There has been an ongoing study in this country for the last twenty years through Harvard. The study involved approximately 145,000 predominantly white, middle-aged or elderly adults. In 1982, these individuals were surveyed regarding multi-vitamin use and then reassessed in 1992 regarding current use of multi-vitamins. The individuals were then followed over the next five years, up to 1997. During that time, approximately 800 people developed colon/rectal cancer. After adjusting for "health conscious" behaviors, those participants who were regular multi-vitamin users ten years before the start of the study (in 1992) had an approximately 30% decreased risk of developing colon/rectal cancer compared to the other groups. Those individuals who had only recently begun taking multi-vitamins did not have an immediate reduced risk of cancer. This makes total sense. Like other degenerative disorders, cancer frequently develops over many months to years. Only by having the protection of continual use of multi-vitamins could there be any long lasting benefit at reducing such disorders. (2003)
