This can help to reduce the prevalence of protein energy malnutrition, anemia , thyroid , disorders , rickets, osteomalacia and xerophthalmia, etc.

Because the nurses are direct care provider in the hospitals , health centres and in the families, they can detect the malnourished people in the families as well as in the baby clinics, antenatal and postnatal clinics. School health nurses have good opportunity to detect undernourished children. There are a number of anthropometric measurements such as weight, height ,arm circumference, head circumference etc. Which can be used to assess nutritional status of the children "Road to health" cards can be used for the purpose . Other methods are periodical surveillance, early diagnosis and treatment of infectious diseases , oral rehydration of children suffering from diarrhea, deworming the infested people , developed of supplementary feeding programs during endemic.

This regular diet may be modified with regard to selection, methods of preparation and consistency for patient who cannot tolerate a regular diet but do not require a therapeutic diet . These modification are liquid diet , soft diet and semi solid diet. Nurses should know different types of modification of diet in the hospital because they are responsible to prepare and administer the nutritional need according to types of disease, age ,income, region, customs and food habits of individual patients.
