'nutriment' (synonym of Āhāra, q.v.), is one of those 8 minimal constituent parts, or qualities, of all materiality, to wit: the solid, liquid, heat, motion; colour, odour, taste and nutriment.

This is the 'octad with nutriment as the eighth (factor)' (ojatthamaka-kalāpa), also called the 'pure eightfold unit' (suddhatthaka-kalāpa), being the most primitive material combination.

For further details, s. rūpa-kalāpa.
