In each episode new items are added to shops and old ones do not disappear. So in Ep.2 there are the most food items in shops. I've listed episodes in which items first appear in either Amanda's Shop or Amanda's Shop (Branch) - white cat on a plane. Most food items can be obtained this way.
However there are a some exception:
Clam Chowder, Steak, Lobster Boil, Fish and Chips, Hot Dog, T-Bone Steak, Pizza can be obtained only by completing Forrest Kaysen Extra Cases.
Coffee, Peanuts, Mini Pretzels, Vegetable Juice, Expensive Tequila, White House Chocolates & A dozen water bottles can be obtained only by locating and interacting with them in game world. Those are the ones people would most often miss.

If you still can't find some of items, I've also uploaded full walkthrough on YT with timecodes of missable items denoted in description.
