1. A nutrient intake amount estimation system comprising:
a sensor that is disposed in a toilet space, and configured to detect an excretion smell related to excretion of a user of the toilet space;
an estimation unit configured to estimate, in accordance with an input based on an output value of the sensor, an estimated nutrient intake amount that is an amount of nutrients taken by the user by using an estimation model configured to indicate a correlation between an amount of nutrients not consumed by the user and the output value of the sensor; and
an output unit configured to output information based on the estimated nutrient intake amount.
