Moreover, this study found that diets high in calcium reduced the risk of colon cancer associated with a high intake of calories.
Calcium therefore appears to counteract any cancer-promoting effect of dietary fat.
Milk calcium significantly increased fecal pH and fecal excretion of phosphate, total fat, free fatty acids, and bile acids. Milk calcium therefore precipitated luminal bile acids and free fatty acids inhibiting their absorption. A reduction in risk was apparent in less than one year. At present, there is no direct evidence that CLA protects against colon cancer in humans.
