How can smartphones help improve health by providing applications such as the Remote Food Photography Method or monitors for blood pressure, glucose levels, or heart rate?
◦ These applications send data to a federal database that then allows researchers to make long-range estimates about the nation's food supply and average per-person intake.
◦ These applications provide a "worst-case baseline" established by national data on obesity and heart attacks, which then prompts users to exceed that baseline if possible.
◦ These applications provide quick and immediate feedback to individuals on health-related behaviors, allowing them to track, monitor, and alter their behaviors if necessary.
◦ These applications consistently overestimate heart rate, food intake, and other measures, which has the effect of causing a person to lower those intake levels and consequently improve health.
