Suck It, Anti-milk Crackpots!
(apologies if you’re genuinely lactose-intolerant)
source Heavy dairy consumers have a 0.87 relative risk for all-cause deaths compared to dairy-avoiders. The numbers (0.77,0.98) are the 95% confidence intervals - i.e. the actual relative risk is almost certainly somewhere between 77% and 98%. A relative risk of .87 means that you’re 13% less likely to die (only (87% as likely to) if you consume a lot of dairy than those who abstain. This is not a prospective study, so you can’t know that increasing dairy intake now will definitely make you less likely to die.
