This volume examines the relationship between nutrition and the aging process and offers nutritional guidelines for promoting and sustaining the health and function of elderly people. Leading international investigators shed new light on the role of diet in age-related physiological changes, the significance of nutritional factors in the etiology of geriatric diseases, the specific nutrient. A study showed a lower daily energy intake in elderly people living at home compared with those living in nursing homes . Therefore, frail people living at home are at risk of insufficient. "Older adults tend to need fewer calories as they age because they are not as physically active as they once were and their metabolic rates slow down. Nevertheless, their bodies still require the same or higher levels of nutrients for optimal health outcomes," advises Alice H. However, some nutrients require special attention in older people. Energy Energy requirements decline with increasing age but it is essential that the nutrient density of the diet remains the same. An energy intake reduced to less than the energy needs of the older person can result in poor nutritional status.
Energy requirements. For healthy people, energy requirements decrease with advancing age. This is due to changes in body composition; a decrease in lean body tissue (muscle) and an increase in fat tissue. This means that, for a given bodyweight, older people tend to have less muscle and more fat, leading to a fall in basal metabolic rate (BMR). In elderly persons, some nutrient needs (e.g., vitamin D) increase, while others (e.g., energy and iron) are reduced. The National Academy of Sciences has published recommendations for Dietary Reference Intakes (DRI) that are specific for the various stages of life. It should be noted, however, that the DRIs are not designed for individuals who. Elderly people should make sure that they avoid eating saturated fat. However, various researches claim that a large number of elderly consumes too much of this fat. On the other hand, elderly people who are frail should include saturated fat into their diet. Fiber. The gut of elderly people is not as active as the one in younger people. Nutrition Problems in the Elderly. Nutritional problems in the elderly can cause a number of complications, including weakened immune systems, lowered energy levels and chronic health problems such as type 2 diabetes, high blood pressure, heart disease, stroke and osteoporosis. Making changes in their diet to match.
Vitamin B12 – You need micrograms of this diet each day, and about one-third of the elderly population is unable to absorb this vitamin naturally from food. Calcium – Older people need between and mg or calcium a day to avoid bone loss and fractures. Older people tend to eat less and the body’s ability to absorb some nutrients also becomes less efficient with age so it can be harder to get all the necessary nutrients for good health. It is important for older people to eat a varied diet to ensure an adequate supply of all the essential vitamins and minerals, and enough food to cover their. Long-term dietary restrictions expose older individuals to inadequate protein–energy and micronutrient intake that may cause a worsening of nutritional status, even more since those people show a higher risk for nutritional deficits comparing to younger people due to physiological, psychological and socio-economic reasons. Dietary Supplements For The Elderly. The demographics are changing rapidly. Life spans have increased and are likely to continue to increase. The average life expectancy of women is now at 79 and for men it is 72, according to the Harvard University Gazette.
