Nutrition and Hydration. We know it’s important for a good quality of life, but we also know it is easy for the elderly to forget to eat and drink properly. We examine how care homes can help residents maintain a good level of nutrition and hydration. Food is fundamental to the quality of life, and for many older people in particular, it can be critical to their health and well-being. Unplanned or unexplained weight loss can make older people more susceptible to catching illnesses. People’s appetites can also reduce as they get older, so ensuring care home residents are eating enough is vital.
