We did a lot of work to evaluate the layout of the diet cards, both in print and on-screen. We found, with hundreds of hours of data collection to support us, that it is much faster to prep from "days on the left" because you only scan down one column (days) and move your eyes right only for the items that occur today. If you list the food first (on the left), then you read every food, even if you don't need that food today, and then must scan every line to the right to see if it should be prepped today. Fundamentally, "days on the left" is about 25-35% faster than "days on the right".
