Introduction
•Food does so much more than simply sustain life. Food is loaded with personal, social, and cultural meanings that define our food values, beliefs, and customs. That food nourishes the mind as well as the body broadens nutrition to an art as well as a science.
•Nutrition is not simply a matter of food or no food but rather a question of what kind, how much, how often, and why. Merging want with need and pleasure with health are keys to feeding the body, mind, and soul.

•Although the dietitian is the nutrition and food expert, nurses play a vital role in nutrition care. Nurses may be responsible for screening hospitalized patients to identify patients at nutritional risk. They often serve as the liaison between the dietitian and physician as well as with other members of the health-care team.
•Nurses have far more contact with the patient and family and are often available as a nutrition resource when dietitians are not, such as during the evening, on weekends, and during discharge instructions.
NUTRITION SCREENING
•Nutrition screening is a quick look at a few variables to identify individuals who are malnourished or who are at risk for malnutrition so that an in-depth nutrition assessment can follow. Screening tools should be simple, reliable, valid, applicable to most patients or clients. For instance, a community-based senior center may use a nutrition screen that focuses mostly on intake risks common to that population, such as whether the client eats alone most of the time and/or has physical limitations that impair the ability to buy or cook food. In contrast, common screening parameters in acute care settings include unintentional weight loss, appetite, body mass index (BMI), and disease severity. Advanced age, and other factors may be considered.
