Nutrition has an impact on general health, especially in the elderly. Malnutrition has been linked to hastened ageing in studies. In fact, eating a balanced diet is acknowledged to be one of the most important factors in ageing well. Adults' nutritional needs do not change significantly with age. However, as people get older, their total calorie intake decreases, but nutritional deficits are uncommon among ordinary people living in the community. Poor and disadvantaged older persons have deficiencies in specific nutritional nutrients. The usage of special diets or megadoses of vitamins does not improve health or lengthen life. Because of the decline in food consumption and the inclination of elderly individuals to consume the same diet every day, they are at risk of vitamin, mineral, and protein deficiencies. A multitude of changes in the body are associated with ageing, including muscle loss, thinner skin, and lower stomach acid. Some of these changes may put people at risk for vitamin deficiencies, while others may have an impact on their senses and overall quality of life.
