Peter Elwood, MD, Professor of Epidemiology at Cardiff University, et al., in their study "Milk Drinking, Ischaemic Heart Disease and Ischaemic Stroke II. Evidence from Cohort Studies," published May 2004 in the European Journal of Clinical Nutrition, concluded:

“Cohort studies provide no convincing evidence that milk is harmful. While there still could be residual confounding from unidentified factors, the studies, taken together, suggest that milk drinking may be associated with a small but worthwhile reduction in heart disease and stroke risk.”
