NABH's accreditation standards treat nutrition as part of patient care. The Care of Patients chapter expects patients to be screened for nutritional risk, those found at risk to be assessed further, and the therapeutic diet to be planned and provided collaboratively. Related expectations cover educating patients and families about diet, and kitchen sanitation and safe food handling.
In practice, that means a trail an assessor can follow. The diet follows the treating doctor's order, a qualified dietitian assesses patients where required, the kitchen handles food safely, and each step is documented. On paper, that trail is spread across case files, diet registers and kitchen slips, and assembling it before an assessment is slow and error-prone.
Accreditation is earned by hospitals, not software, and your quality team should always work from the current NABH standards. What MedMeals changes is the evidence: the dietary part of the trail is built while your teams work.
