Here Come the Artificial Intelligence Nutritionists

DayTwo is just one of a host of apps claiming to offer A.I. eating solutions. Instead of a traditional diet, which often has a set list of "good" and "bad" foods, these programs are more like personal assistants that help someone quickly make healthy food choices. They are based on research showing that bodies each react differently to the same foods, and the healthiest choices are likely to be unique to each individual. Whether these A.I. nutritionists are ready for widespread use is still unclear, and there is very little research available from sources outside the companies selling apps. Users should be wary of overly broad claims that go beyond predicting how foods affect blood sugar.
