Intake of Calcium and Dairy Foods Inversely Associated with Risk of 
Colorectal Cancer

Reference: 	“Calcium and dairy food intakes are inversely associated 
with colorectal cancer risk in the Cohort of Swedish Men,” Larsson SC, 
Bergkvist L, et al, Am J Clin Nutr, 2006; 83(3): 667-73. (Address: 
Division of Nutritional Epidemiology, National Institute of 
Environmental Medicine, Karolinska Institutet, Stockholm, Sweden.

Summary: 	In a prospective study involving 45,306 men from the Cohort of 
Swedish Men, aged 45-79 years, without a history of cancer at baseline, 
high intakes of calcium and dairy foods were found to be inversely 
associated with risk of developing colorectal cancer. Subjects were 
followed for a mean of 6.7 years, during which 449 incident cases of 
colorectal cancer were ascertained. Calcium and dairy food intake were 
assessed via a food-frequency questionnaire completed by subjects. After 
adjusting for age and other known or potential risk factors, subjects in 
the highest quartile of total calcium intake had a multivariate rate 
ratio (RR) of colorectal cancer of 0.68, compared with subjects in the 
lowest quartile of calcium intake. For subjects who consumed at least 7 
servings/day of total dairy foods, the multivariate RR was 0.46, 
compared with subjects who consumed less than 2 serving/day total dairy 
products. These results suggest that in men, a diet high in calcium 
and/or dairy foods may be associated with a reduced risk of colorectal 
cancer.
