Magnesium and rectal ca risk.

Higher magnesium intakes are associated with decreased risk of rectal cancer in women, reported Susanna C. Larsson of the Karolinska Institute, Stockholm, and her colleagues.

After a mean follow-up of nearly 15 years, women with magnesium intakes in the top quintile (at least 255 mg/day) had a rectal cancer risk that was 55% lower than the risk in women with magnesium intakes in the bottom quintile (less than 209 mg/day). Risk reductions were 52%, 46%, and 36%, respectively, in the second-highest, third-highest, and fourth-highest quintiles. The prospective study included about 61,000 women in the Swedish Mammography Cohort who completed a questionnaire between 1987 and 1990 and a second questionnaire in 1997 (JAMA 2005;293:86-9).
