Too much milk fat in your diet can lead to colitis. That is the findings of a paper published ahead of print on the Nature website by a group from the Gastroenterology Section of the Department of Medicine, University of Chicago.
Mice were fed one of three diets consisting of low fat, saturated fats or polyunsaturated fats. The diet containing saturated fats (milk fat) led to a bloom in a sulphite-reducing microorganism B. wadsworthia that can cause inflammation of the colon (colitis). This was not observed in the diet containing polyunsaturated fats.
