    "body_text": "Rush researchers reanalyzed data from the three-year MIND diet trial and found that cognitive response varied with baseline blood levels of amyloid beta 40 and phosphorylated tau 181. Participants with higher markers appeared more likely to benefit from the dietary intervention. The original trial did not find a statistically significant overall cognitive advantage over its control diet, and this post hoc analysis was designed to find patterns rather than confirm a prespecified treatment effect.",
