In the latest volley in the debate over milk, a long-running Scottish study contradicts other studies that suggest milk consumption might contribute to coronary problems. In fact, the study found that milk drinkers were significantly healthier than non-milk drinkers.
The study followed 5,700 Scottish men for a period of 25 years. The study found that even among men who drank whole milk, there was no increase in the risk of heart disease compared to those who didn’t drink milk. In fact, heart disease among regular milk drinkers was found to be lower than among non-milk drinkers.
The researchers were quick to emphasize that this applies to moderate milk drinking. Dr. Andy Ness told the BBC, “We are not talking about people who are drinking pints and pints of milk, but a moderate consumption of about a third of a pint a day. Our study does seem to show that a bit of what you like does seem to do you good.”
Reading between the lines of the study, however, the clearest implication is that whatever health effects milk has on the body, it is minor compared to other behaviors. For example, their study found that deaths from cancer and strokes were 10 percent lower in the men who were regular milk drinkers than those who weren’t. But, this was almost certainly attributable to the fact that those who didn’t drink milk at all were more likely to smoke than those who drank milk regularly.
Also, as is the case with a lot of the studies that show meat consumption or some combination of meat consumption is unhealthy, when people see studies saying a certain food causes an increase or decrease in death rates of 10 percent, they should be extremely skeptical since it is all but impossible to accurately detect such small risk factors in epidemiological studies.
