Does it need to be, though? You can survey healthy but senior populations about their habits, and then over the following years track what happens.
If medical records were public, the answers could even be in those for any medicines that are prescription based. You could then make statements like "A% of patients who took drug B within C years did/didn't develop disease D".

An RCT doesn’t prove causation, it only might observe another correlation that contributes to our causal inferences based on the convergence of evidence. We don’t have RCTs for most things that you take for granted.
