As people age, their levels of nutrition and energy decline. We are aware that albumin is a protein found in blood. Malnutrition and reduced liver activity are the main causes of the reduction in albumin protein levels. Malnutrition results in reduced protein intake, poorer protein absorption, and increased gastrointestinal protein loss. Due to edentation, many elderly people avoid meat. The elderly want to consume soft foods unbothered. As people get older, their livers produce fewer proteins and their functions decline.
