Problem

• Scanning individual products is tedious if you want to get a compilation of nutrition facts for many items.
• You can think of a grocery trip as the main input of your nutrition, so we could use that compiled information (a receipt) as a means to get a better understanding of what will be consumed until the next grocery trip.
• Bottom line - calories purchased, calories consumed (mostly).

Proposed solution

1. Scan receipt from a particular store
2. Search database for the products (need to input receipt names to product to connect names<>barcodes, if barcode not included on receipt)
3. Sum nutrition content for each product and output totals for that receipt

Alternative solution, not requiring database connection between receipt names and barcodes:

1. Scan all purchased items from store and add to 'Grocery Trip' list
2. Sum nutrition content for each product and output totals and display
   ** This solution may incentivize more product scans since you users will scan everything they've purchased!
   ** Downside to this method is repetitive for regularly purchased items. This is where the previous solution outperforms.

Additional context

• Assuming you're buying a week's worth of food and consuming it all within that week (which many people do), you can average your nutritional intake across that week.
• Scanning a receipt from one grocery store can provide the summed metrics for all the food you bought (and will consume) so you can know how much of each macronutrient you will be having for that week (averaged).
