DASH Cloud: Using Digital Health to Improve Adherence to the DASH Diet Among Women

With DASH Cloud, the investigators will ask participants to track their diet daily using a commercial diet tracking app. The investigators will retrieve the diet data on our DASH Cloud platform and provide tailored feedback about a participant's DASH adherence via fully automated daily or weekly text messages. These feedback messages will describe both an individual's absolute performance and change over time. The investigators also include theory-driven tailored content that reinforces successes, offers motivational strategies, and offers short behavior change tips.

DASH Light Control participants will be asked to use the Nutritionix app daily and receive publicly available written materials on the DASH diet.
