"A large observational cohort study[1] in Sweden found that women consuming more than 3 glasses of milk a day had almost twice the mortality over 20 years compared to those women consuming less than one glass a day. In addition, the high milk-drinkers did not have improved bone health. In fact, they had more fractures, particularly hip fractures."
Which is a misleadingly confident interpretation of the cited paper which concludes with:
"High milk intake was associated with higher mortality in one cohort of women and in another cohort of men, and with higher fracture incidence in women. Given the observational study designs with the inherent possibility of residual confounding and reverse causation phenomena, a cautious interpretation of the results is recommended."
Beyond correlation =/= causation, note the trepidation in the referenced authors conclusion. Furthermore some of this has been subsequently contradicted by other studies[0] (probably why the Swedish authors had hesitation). [1] provides a more detailed explanation of why the originally referenced study has limited interpretability.
Avoid milk all you want but suggesting "milk is bad for you" is supported by evidence is very misleading, there is conflicting poorly controlled observational evidence on both sides of the discussion. If you like milk, drink it within reason and don't feel bad (for your health).
