3 ways AI is already changing medicine

When Dr. Eric Topol joined an experiment on using artificial intelligence to get personalized nutrition advice, he was hopeful. For two weeks, Topol, a cardiologist at Scripps Research, dutifully tracked everything he ate, wore a sensor to monitor his blood-glucose levels, and even collected and mailed off a stool sample for an analysis of his gut microbiome. The diet advice he got back stunned him: Eat Bratwurst, nuts, danishes, strawberries, and cheesecake. "It was crazy stuff," Topol told me. Bratwurst and cheesecake are foods Topol generally shirks because he considers them "unhealthy."
