Iron Gut

Iron Gut is a duplicant trait that allows a duplicant to eat virtually any food without becoming sick. Descriptions across supported language sources consistently state that a duplicant with Iron Gut does not suffer adverse effects from consuming a wide range of edibles that would normally make others ill.

Duplicants with Iron Gut are therefore reliable when your colony needs flexibility in food choices. They will accept and consume unusual, marginal, or otherwise risky food items without the reported sickness that affects duplicants lacking this trait. The trait is presented as a straightforward immunity to food-caused illness; it does not, in the available descriptions, include other effects beyond this capacity.

• Useful for tasks that require dietary flexibility, such as when conventional food supplies are low or when the colony must make use of unconventional food sources.
• Reliable for assigning to eat a broader variety of available rations without concern for food-related health problems.
• The trait’s function is described identically in multiple locales, indicating a consistent role across language versions: the duplicant simply does not get sick from foods that might harm others.

This article limits itself to the trait’s documented effect: immunity to becoming sick from eating almost anything. No further mechanics, bonuses, penalties, or interactions beyond that core description are asserted in the cited sources. If you require detailed in-game mechanical behavior (specific immunities, interaction with spoiled or contaminated food, effects on morale or consumption rates), consult in-game tooltips or the game’s primary documentation for mechanics beyond the scope of the provided trait descriptions.
