It would be useful to correlate and run experiments with nutrition data such as calories, carbohydrates, micro nutrients, minerals, etc.
Would like this – and it could just pull this data from Apple Health.
Several food trackers including Cronometer, MyFitnessPal, Yazio etc. are capable of writing food data to Apple Health, so we’re planning to add food macro- and micro-nutrients to the existing Apple Health integration to support as many of these apps at the same time as possible. Will keep you posted as this develops! In the meantime, if you’re using one of these trackers, we recommend enabling it to write to Apple Health so that data will be available for download in Reflect once this feature is released.
