Healthy food that's often taken by nurses (5)

Ross

I believe the answer is:

pulse

This clue is a double definition.

'healthy food' is the first definition.
(pulses are healthy food)

'that's often taken by nurses' is the second definition.
(a nurse might take a patient's pulse)

(Other definitions for pulse that I've seen before include "Throb, beans" , "Rhythmic throbbing" , "Pound" , "A vital sign turning" , "Beat or throb of heart" .)

I've seen this clue in The Times.
