Interactions between nutrition and the ageing process are a fascinating field of research. The assessment of the nutritional status is an important part of medical examination. Generally it is assumed that energy intake and energy expenditure decrease with age. In fact they vary widely and are very different in healthy, in sick or in institutionalized elderly. Nutritional requirements depend on many social and physiological factors in the free-living elderly population. Surveys indicate that dietary requirements are qualitatively grossly comparable to those in middle-aged adults.
The health (self-reported health conditions) and nutritional status (food and nutrient intake, nutritional biochemistry, anthropometry) of 189 elderly Greeks living in Melbourne, Australia were described and compared with 104 elderly Greeks living in a rural town in Greece (Spata) using a validated health and food frequency questionnaire. Spata was chosen because the traditional diet is maintained by the community and may act as a 'surrogate' measure of diets prevalent in Greece prior to the Melbourne sample's migration to Australia in the 1960s.
The current adult guidelines for a healthy diet make no distinctions between adults aged 25-50 y and those aged 51 y and over. The question is whether dietary guidelines ought to be stratified by age, in recognition of the dietary and nutrient needs of the growing population of elderly adults. There are limited data on nutrient requirements of older adults. Aging is accompanied by a variety of physiological, psychological, economic and social changes that may adversely affect nutritional status.
Despite the recognized role diet plays in disease, health, and longevity, less than half the US population consumes the desired 5 fruit/ vegetable servings a day. What accounts for the disjunction between cognition and behavior? Telephone survey data from a probability sample of 308 metropolitan Washington, DC, residents confirm the contingent consistency hypothesis as one explanation. The hypothesis suggests that optimal beliefs about health outcomes of dietary intake motivate optimal dietary intake, contingent on social structural experiences.
Nutrition offers the means to improve health and well-being and among the predictive factors of successful aging, nutrition appears as one of the major determinants. Whereas adequate nutrition plays a major role in a healthy lifestyle that maintains bodily and mental functioning, inadequate nutrition contributes to a loss of function and to the development and progression of disease. At the moment recommended dietary allowance (RDA) is established to cover the needs of populations of the healthy elderly.

OBJECTIVES: The aim of this work was to evaluate the correlation between the amount of weekly fish intake and kidney function as measured by creatinine clearance (CCr) rate among elderly inhabitants of Ikaria Island, a place that has been related to an increased rate of longevity. METHODS: From June to October of 2009, 673 males and females, aged 65-100 years and long-term residents of Ikaria Island were enrolled. Of those, 328 (75†±†7 years) were males and 339 (75†±†6 years) were females.
BACKGROUND: Hemodialysis (HD) in infants is usually used when peritoneal dialysis (PD) has failed. We describe our experience with HD, outlining the morbidity, complications, and outcomes for infants weighing less than 10†kg managed with HD for more than 6†months over a 10-year period. METHODS: A retrospective review of the clinical notes was conducted to collect demographic information, anthropometric data, dietary history, site and form of vascular access, details of HD prescription, complications, and outcomes.
BACKGROUND: Invalid information on dietary intake may lead to false diet-disease associations. This study was conducted to examine the relative validity of the food frequency questionnaire (FFQ) used to assess dietary intake in the Leiden Longevity Study. METHODS: A total of 128 men and women participating in the Leiden Longevity Study were included in the present validation study. The performance of the FFQ was evaluated using the mean of three 24-hour recalls as the reference method. Evaluation in estimating dietary intake at the group level was done by paired t-tests.
Although hypersensitivity to foods is often linked to exacerbations of symptoms of respiratory allergy, no such information is available regarding the foods traditionally considered to play a probable etiological role in respiratory allergy in India, which are in fact quite different from the ones implicated in the West. The present study was undertaken to investigate whether the practice of withholding certain common foods by parents and practitioners of indigenous systems of medicine (i.e.
Because of the number of factors affecting the nutritional and metabolic status in patients with advanced chronic kidney disease or who are on maintenance dialysis, the prevention and treatment of protein-energy wasting (PEW) of chronic kidney disease should involve a comprehensive combination of maneuvers to diminish protein and energy depletion, in addition to therapies that will avoid further losses.
