So I was in the middle of the sea, searching for new land, had a map(9) and some food(8) on me, so I wanted to see where I was going so I switched threw the inventory. I passed my tools and weapons, came to the food and the map, left clicked the map and ate it. I later found out that you can eat every item if you timing it right, select any food, switch to any item, wait like 500ms and left click, item gone forever, food still there :c
