Milk is on my mind, still

New headlines! The BMJ just published a report on milk intake and risk of mortality and fractures. The review examined two large (61,5k and 45,5k participants = 107 000 subjects in total) cohort studies, to which they applied multivariable survival models for the purpose of determining the association between milk consumption and time to fracture or mortality. In both cohorts, higher milk intakes correlated with higher mortality (so, in both men and women), and in the female group the intake was also associated with higher fracture incidence.

Sure, this is just one review (though with a huge study population), and sure, a huge risk of recall bias is always present when we’re talking about self-reports of food consumption. Nevertheless, when we have a dairy industry that claims that a diet which is rich in their products reduces the risk of osteoporotic fractures, and when consuming around 3 glasses of milk per day is said to reduce osteoporosis-related healthcare costs by 20%, which is completely contradictory to scientific evidence, we may have to stop and think for a minute.

In addition, milk is the chief dietary source of D-galactose (a sugar). Experimental evidence indicates that chronic exposure to D-galactose is harmful to one’s health, and injecting a low dose thereof in experimental animals induces changes that resemble natural aging. It causes shortened life span via oxidative stress, chronic inflammation, neurodegeneration, decreased immune response, and changes in gene transcription — would you like a glass of milk with that?

  1. Hi Eva! Really interesting article (and your whole blog!). I’ve read about this subject befores, but I’m always the same doubt: what happen with yogurt and cheese? They have the same effect on health? I appreciate your time and attention. Have a nice day!

    • Thank you, I’m really happy you like it! Yogurt and cheese, with respect to bone health, was not found to have detrimental effects – in this study. With other considerations in mind such as saturated- and trans-fats, which negatively affects your blood lipid profile, health concerns may be more prominent.
