I have had mild lactose intolerance since childhood. This means that I have no problems with butter or ice cream or milk in my coffee and tea and cereal and in other foods but cannot drink a full glass of milk with getting an upset stomach. It turns out that what I thought of as a limitation and even a minor health hazard (milk is good for you, right?) may actually be a positive thing. While butter and eggs got the green light some years ago, switching from being bad for you to being either good or neutral, a new study suggests that milk may go the other way, switching from being an unalloyed good to health hazard.
A new study from Sweden involving over 100,000 people observed over a period of 20 years finds that people who have more than a glass of milk a day have higher mortality rates and, even more surprisingly, that the risk of bone fracture in women increases. The study authors say that the last finding should be treated with caution because women who had reason to fear bone fractures for other reasons may have drunk a lot more milk, thinking of it as a preventative measure.
Look for future studies, maybe funded by the dairy industry, to see if this conclusion holds up. That industry has invested a vast amount of money enlisting all manner of celebrities in their Got Milk? ad campaign and made the milk mustache a badge of honor, though it dropped that campaign earlier this year in favor of a new one in order to boost sluggish sales. This study will be a cause of concern to them.
