Abstract: | The association between standardized cancer mortality rate ratios from 1969-1978 and dietary practices was examined in an ecologic study of the 24 counties of Sweden by means of several independent data sources. The study supports the hypothesis that a high intake of cereal fiber protects against colorectal cancer (r = -0.75 for males and r = -0.67 for females). This study found no association between fat intake and colorectal cancer. However, a negative correlation between milk consumption and this type of cancer was found. A suggested hypothesis is that calcium protects against colorectal cancer, since milk is the major source for calcium intake in Sweden. This could indicate that, for societies with a high fat intake, preventive measures which increase the intake of fiber and milk or calcium might have a greater impact on mortality from cancer of the colon and rectum than would a moderate decrease in the intake of fat. There are no indications in this study that fat intake promotes breast cancer. |
