How much feces does one human consume in a lifetime?

On average, a human consumes about 70,000 meals in a lifetime, but the amount of feces ingested is not a standard measure or commonly tracked. Theoretically, if one were to consider the average fecal matter produced and potential contamination through various means, the amount could be negligible compared to overall food intake. However, the concept of directly consuming feces is more relevant in discussions of hygiene and health risks than in calculating a specific lifetime amount.
