What food group does Tapioca pudding belong?

Tapioca pudding primarily falls into the grain group.

Here's why:

* Tapioca is made from cassava root, which is a starchy root vegetable.

* Starchy root vegetables are classified as grains in the USDA Food Guide.

* Tapioca pudding is primarily made of tapioca starch and milk, making it a grain-based dessert.

While tapioca pudding also contains milk, which is a dairy product, the primary ingredient and source of carbohydrates is the tapioca starch.
