They are stats which steadily deplete when playing on Survival Mode. The player must maintain their hunger and thirst levels by consuming food and water items. If either stat reaches zero, the player will lose health until they die.  -**Sustenance** refers to the category of consumable items crafted from certain **Raw Materials** and **Fauna** using the **Fabricator**. While fish can be eaten raw, using the Fabricator to cook them increases their nutritional value and removes any dehydration penalties associated with raw consumption.+**Sustenance** is a category of consumable items crafted from certain materials and fauna using the Fabricator. While fish can be eaten raw, using the Fabricator will increase their nutritional value and remove their dehydration penalty.  -To consume an item, press the "Use" keybind while the item is selected in the **PDA**. Some foods also provide health regeneration when consumed.+To consume an item, press the "Use" keybind while the item is selected in the PDA. Some foods will also heal the player when consumed.   ## Mechanics  -The player's current Food and Water levels are displayed as gauges alongside their **Health** and **Oxygen** meters in the bottom-left corner of the **HUD**. Each gauge represents a value ranging from 0 to 100 points.+The player's current food and water levels are displayed as gauges alongside their Health and Oxygen meters in the bottom left of the HUD. The gauge corresponds with the stat's current value, which ranges from 0 to 100 points.  -### Depletion Rates+In Survival, the player loses 1 unit of water every 15 seconds, and lose 1 unit of food every 21 seconds, unless they are using the Slow Metabolism biomod, which doubles the time to 42 seconds.  -In Survival Mode, stats deplete at the following rates:+## List of items  -*   **Water**: Loses 1 unit every 15 seconds.-*   **Food**: Loses 1 unit every 21 seconds.- -These rates can be improved by using the **Slow Metabolism** biomod, which doubles the time between depletion ticks (e.g., food depletes every 42 seconds instead of 21).- -## List of Items-  ### Prepared Meals  -Prepared meals are crafted items that often provide significant benefits, including health restoration.-  | Icon | Item | Food | Water | Health | | :--- | :--- | :--- | :--- | :--- |-| ![Sugar of Saturn](wiki-images/fd/fd9707f3b520f09e0fb5f49d6c6ab3a0.png) | [Sugar of Saturn](Sugar_of_Saturn) | +10 | -
