In order to earn this trophy, each unique food and drink in the game has to be consumed. Food and Drinks are items (which there are plenty of) that restore health, and remove status effects on the player when consumed. There are 30 different types of food/drinks (20 types of food, 9 different drinks, and 1 Super Fruit obtained by finishing the Gardening Tips Side Mission), and many of them don't have a specific location in which they are found. They can be generally found in shelves, desks, refrigerators, on top of tables, etc. They can also be looted from Human and at times Typhon corpses.When food/drinks are found, they can be taken into your inventory by pressing  or immediately consumed by pressing  . It's recommended to keep track of which food and drinks are consumed personally, and also to scour and search every inch of the game when doing the first playthrough. This playthrough as outlined in the Roadmap is for earning all miscellaneous trophies, and this trophy is no exception.Note: All the food and drinks don't even have to be consumed to earn this trophy. This trophy can be earned after consuming around 80% of the food and drinks combined. Depending on the game, you can unlock this trophy after consuming 22-26 different food/drinks.Here is a list of all the types of food and drinks that can be found in the game:

Xiphophurus has suggested that eating the Super Fruit grown in the Gardening Tips side mission can also count for the trophy. This is for people who have eaten all types of food and still can't unlock the trophy. Complete the side mission, and eat the fruit. This could help in unlocking the trophy. Thanks Xiphophurus!
