In a Swedish study published last month in JAMA Open Network, meat consumption was associated with cognitive health in individuals with a genetic risk for Alzheimer’s.

Does it mean avoiding meat increases risk–i.e., should vegetarians worry that their diets are accelerating cognitive aging? (Hint: I would.)
In my latest Substack newsletter, we take another trip into the nuances of nutritional epidemiology, particularly the implications of the anti-randomization problem.
