“…These data suggest a low prevalence of Zn deficiency in free-living ageing European people. This low prevalence of Zn deficiency in a free-living elderly population confirms previous data from others studies which report prevalence at 5% in a study in Boston and 3-4% in EuronutSeneca European-based study (Bailey et al, 1997), but are very different from data reported in hospitalised elderly, in which 28% (Pepersack et al, 2001) or 38% had plasma Zn below the cutoff value of deficiency (Schmuck et al, 1996).…”

“…Expressed on a MJ food energy basis, Zn intake was 1.2970.38 mg/MJ in middleaged vs 1.4170.76/MJ in older. The nutrient density was significantly higher in older than in middle-aged and close to the Adequate Nutrient Density, 1.89, calculated to allow recommendations to be met with an energy intake of 6.36 MJ/day (Schmuck et al, 1996). Therefore, this data suggests Zn intakes in this older free-living population are There is no significant sex difference for the three mentioned Zinc status parameters in middle-and older-aged subjects.…”

“…Most of the studies in elderly which assessed the prevalence of Zn deficiencies were among hospitalised elderly, or focussed solely on the relationship between Zn status and humoral immune function in ageing (Pepersack et al, 2001). Inadequate Zn intakes as well as alterations of Zn status have been especially demonstrated in hospitalised people (Schmuck et al, 1996). However, data on Zn intakes and status in elderly free-living people and within normal ageing are scarce.…”

“…Our group recently reported decreased Zn pools in free-living or institutionalised older, but this was dependent on lifestyle factors (Faure et al, 2005). In institutionalised or hospitalised aged people, a high prevalence of Zn deficiency is well documented by several European studies (Schmuck et al, 1996;Girodon et al, 1999;Pepersack et al, 2001). However, for free-living older subjects (over 70 y), little research has been conducted, specifically regarding zinc intakes, status and specific needs (Sibai et al, 2003).…”

Objective: Inadequate intakes of micronutrients in elderly negatively affect the nutritional status. Zinc is an essential micronutrient in the elderly, especially in relation to its impact on immune function, bone mass, cognitive function and oxidative stress. However, data are lacking on zinc intake and status during normal ageing. In this study, we evaluate the intake and status of zinc in late middle-aged and older free-living subjects. Design: Dietary zinc intake and zinc status in 188 middle-aged subjects from Clermont-Ferrand (Fr) and Coleraine (UK), and in 199 older subjects from Grenoble (Fr) and Roma (It) were assessed at the entry in the ZENITH study. Results: In relation to the zinc RDA for people older than 55 y, zinc intakes in most of the middle-aged and older subjects (more than 96%) in the present study were adequate. Older people had significantly lower (Po0.01) energy intakes as compared to middle-aged. Zinc intake expressed per MJ was also significantly (Po0.01) higher in older people compared to middle-aged. Erythrocyte and urinary zinc concentrations were significantly (Po0.001) higher in middle-aged subjects compared to older ones. The prevalence of biological Zn deficiency in free-living ageing European people was low (o5%). Conclusion:The results of the present study showed a relatively low prevalence of zinc deficiencies in healthy free-living late middle-age and older subjects. These results should be useful for health professionals to have reference data on zinc intake and status for a healthy ageing.

“…Nevertheless many authors have reported that elderly individuals have lowered Cu-Zn superoxide dismutase (EC 1.15.1.1), catalase (EC 1.11.1.6) and GSH peroxidase (EC 1.11.1.9) activities in erythrocytes (see Ceballos-Picot et al 1992). In France, we recently observed that modifications in antioxidant defences were significantly more important in institutionalized elderly individuals than in healthy free-living elderly individuals (Monget et al 1996b;Schmuck et al 1996). In fact, institutionalized individuals should receive particular care with respect to their antioxidant status.…”

Ageing (and related diseases) may be described as a process which results from impaired immunological, genetic, neurological or endocrinological functions. Oxidative mechanisms may play an important role in the ageing process. It is important, therefore, to emphasize the relationship between health and nutrition in the elderly, particularly with regard to antioxidant micronutrient requirements. Indeed, accelerated ageing may be related to a deficit in the intakes of antioxidant vitamins (tocopherols, carotenoids and vitamin C) and trace elements (Zn and Se), as well as to an impaired adaptative mechanism against oxidative stress. Physiological modifications occurring during the lifetime and environmental influences are significant factors contributing to the impairment of micronutrient status, and these factors have to be considered when defining the specific requirements of the elderly. For Fe there is no evidence of benefit of supplementation in healthy subjects, but in the present state of knowledge combined supplementation, including Zn, Se, vitamins C and E and carotenoids, could be the best way to prevent accelerated ageing and reduce the risk of several common age-related diseases. Résumé De nombreuses théories (immunologique, génétique et neuroendocrinologique) ont été proposées pour expliquer les processus de vieillissement et les pathologies qui s’y rapportent. Les mécanismes oxydatifs pourraient contribuer à ces processus et plus particulièrement à leur accélération. La théorie radicalaire repose sur une modification avec l’âge du rapport prooxydants ou antioxydants dû à une majoration des processus oxydatifs accompagnés d’une diminution des systèmes de défense subséquentes à une carence en un ou plusieurs micronutriments antioxydants. Les modifications physiologiques qui accompagnent le vieillisement et une alimentation sélective contribuent aux modifications d’apport et d’absorption des micronutriments. Ces altérations sont accentuées lors de pathologies chroniques. Il n’existe pas de réel consensus sur les recommandations d’apports en oligoéléments adaptés au sujet âgé. Néanmoins les études récentes montrent qu’une association zinc, sélénium, vitamines antioxydantes (vitamines A et E et caroténodes) pourrait être le moyen le plus efficace de lutte contre les pathologies du grand âge et également de prévention du vieillissement accéléré.

Elderly individuals have a higher risk to develop trace element deficiencies due to modified dietary habits and requirements, age related physiological changes, drug therapy, and chronic diseases leading to or associated with enhanced consumption or excretion of trace elements. This review gives an overview about the role of zinc, iron, selenium, copper, chromium and fluoride for the health of elderly people in regard of physiological functions, trace element status and intake, and effect of supplementation on clinical parameters and disease outcome.
