All medical advice is inevitably biased by who doctor's see - not who they don't see. Pediatricians encountered peanut allergies, so they took action - cardiac patients appear with high blood pressure, so action is taken. Advice appropriate for individuals entering a hospital for emergency care is likely inaccurate for the general population. Human anatomy is so immensely complex that it's unlikely that a recommendation based on averages will have positive outcomes for most individuals unless the effect size is extremely large. Bus accidents are still bad for everyone's health.
