"Drinking Milk Cuts Diabetes Risk" blare the headlines. The University of Cardiff in England just completed a study that showed that the more people drank milk the lower their incidence of metabolic syndrome, which is essentially a grab bag of symptoms that can lead to diabetes and heart disease: insulin resistance, obesity, high blood pressure, etc.
One problem. The study did not specify what the control group drank. Think about it. If there was one group drinking more milk, what would the other group likely be drinking? Water with stevia? Doubt it. They were probably drinking more soda and sugared energy drinks.
So, perhaps the headlines should have read "Milk Better Than Soda." Yeah, well, what isn't?
Further, the study reports that the number of people in the control group versus the milk-drinkers was virtually the same as far as who was actually diagnosed with diabetes during the study. The metabolic syndrome rate was lower in the milk-drinking group, but the rate of diabetes was the same, even given the twenty-year span of the study.
A better-conducted study from 2000 showed that cow's milk actually increases the incidence of diabetes by a factor of three. The results of that study are here.
