Al3STR.ACTProvided is a liquid food that can be fed by free fall and has a more physiologically favorable viscous property than a liquid food having a very low viscosity. The use of a water-absorbing dietary fiber and/or a starch not having been subjected to pregelatinization treatment in advance enables the provision of a nutritional composition which maintains a viscosity at which the production thereof is facilitated from the step of mixing raw materials to the step of filling a container with the resulting mixture, and which, after heat treatment, has a viscosity suitable for a flexible container with an outlet used for tube feeding by free fall or for oral feeding.
