Enjoyment of food is regarded as an important aspect of living by mankind. To lead a healthy and active life, human beings need a broad range of nutrients. Nutritional deficiency, particularly of proteins, is very common in the elderly. A well-proportionate diet is essential from the beginning stages of life for complete growth, development, and maintenance of normal body functioning, physical activity, and health.Dentistry for the elderly must be practiced with increased awareness of the biologic factors, since the adaptive mechanism and tissue regenerative potentials in the elderly patients are usually significantly lowered. Over 60% of the elderly are malnourished, and there are many causes for this malnutrition. Also, it is not always easy to differentiate the age-related causes from the pathological. Complete denture patients depend on the health and integrity of the denture-bearing tissue for their successful function and comfort. Hence, the elderly require a different approach, modified treatment planning, and knowledge of how the tissue changes associated with senescence affect oral health services. In this review article, a brief overview is presented about the diet and nutrition of geriatric patients, its importance, and clinical significance.
