Optimum Daily Intake

Optimum Daily Intake (ODI) is a dietary guideline that is improved to meet optimal nutrition, instead of the bare minimum to prevent ailments.

Recommended Daily Intake (RDI) has been found to be the minimum levels of vitamins and minerals required to sustain bodily processes. Dietary Reference Intake (DRI) is an alternative recommendation to ODI. Nutrients aside from vitamins and minerals are also covered by ODI, such as phenols and previtamins from plants.

The idea of Optimum Daily Intake has been around since the 1930's, including rarely since then, but its use has been established since the late 1990's.
