Digestive Incompatibility Is The Food Fix
Subnautica 2 starts you with Digestive Incompatibility, so local fish and alien recipes can fail as hunger food even when they look edible. The fix is the Digestion gene: find the Angel Comb near Anita black box, interact with it, then confirm Digestion in your Adaptations tab.
Fast route. Read Anita in NOA, swim northeast from the Lifepod toward the black box signal, touch the Angel Comb central pod, and collect Anita black box below it before you leave.

Questions People Ask
Why can't I eat food in Subnautica 2?

Is Digestive Incompatibility a bug?
No. It is an intended survival rule. The game expects you to solve it through an alien adaptation, not by crafting a normal food item.
Where do I get Digestion?
At the Angel Comb near Anita black box. Read Anita in NOA, swim northeast from the Lifepod, interact with the central pod, then check PDA -> Adaptations.
