Eating is not simply a significant element of comfort in life or a tradition, but also a vital necessity. Delayed and/or insufficient feeding is not an optimal medical care. Assessment of nutritional risk allows for a timely and optimal nutrition support. Recommended indications and contraindications to nutritional support must be followed. Both underand overnutrition are detrimental to the patients. Follow-up and re-evaluation of the nutritional support of patients is mandatory. Credibility and visibility of nutrition services are improved by written internal protocols and consultations reports, as well as by audits and surveys. Continuous education in clinical nutrition for all categories of health care givers is highly recommended.
