Diet is one of the most challenging lifestyle factors impacting patients with diabetes. There is no good way to log nutrition intake. Patients are asked to recall food consumed, describe how they were prepared, and estimate portions consumed. Evaluating food purchases (for the family) offers an objective approach to calculating nutrition intake and move away from subjective estimations. As a first step, we developed a tool that captures Kroger food purchases and an algorithm that extracts and calculates macro-nutrients.
