It has been suggested that children who consume a low fat diet can meet their micronutrient recommendation by appropriate selection of certain low fat foods (Peterson and Sigman- Grant buy discount aurogra 100mg, 1997) purchase aurogra 100 mg without a prescription. This is especially true for older children whose diets are typically more diverse. The tables in Appendix K show the intakes of nutrients at various intake levels of carbohydrate. With increasing intakes of carbohydrate, and therefore decreasing intakes of fat, the intake levels of calcium and zinc markedly decreased in children 1 to 18 years of age (Appendix Tables K-1 through K-3). Several surveys have evaluated the impact of added sugars intake on micronutrient intakes in children (Table 11-5). In a study of British adolescents, reduced intakes of calcium, phosphorus, iron, vitamin A, vitamin D, and folic acid were associated with increased sugars intakes (mean added sugars intake for the high sugars consumers was 122 g/d for boys and 119 g/d for girls) (Rugg-Gunn et al. In a smaller survey (n = 143), added sugars intakes at levels as high as 27 per- cent of energy did not have a significant impact on micronutrient intakes (Nelson, 1991). This reduction in micronutrient intake was most significant when added sugars intake levels exceeded 25 percent of energy. Bever- ages, particularly soft drinks, were important contributors to the increased carbohydrate consumption. During this period, micronutrient intakes (except for iron) did not increase and calcium intakes decreased. This was attributed to the fact that increased energy was largely obtained from soft drinks, which do not add nutrients and displace milk in children’s diets, with negative consequences for total diet quality (Morton and Guthrie, 1998). Children who were high consumers of nondiet soft drinks had lower intakes of riboflavin, folate, vitamin A, vitamin C, calcium, and phosphorus in comparison with children who were nonconsumers of soft drinks (Harnack et al. Juice (100 percent fruit or vegetable juice) consumption was posi- tively associated with achieving vitamin C and folate recommended intakes in all age groups, as well as magnesium intake among children aged 6 years and older. Soft drink intake was negatively associated with achieving rec- ommended vitamin A intake in all age groups, calcium in children younger than 12 years of age, and magnesium in children 6 years of age and older. Others have shown that children who consumed milk at the noon meal had the highest daily intakes of vitamin A, vitamin E, calcium, and zinc, whereas the opposite was true for children who consumed soft drinks and tea (Johnson et al. Hence, beverages that are major contributors of the naturally occurring sugars, such as lactose and fructose, in the diet (e. The findings from three surveys on the relationship between total sugars intake and micronutrient intake in children are mixed (Table 11-6). Gibson (1993) did not observe reduced micronutrient intakes when total sugars intake exceeded 25 percent of energy. A linear reduction in several micronutrients was observed with increasing total sugars intake (Farris et al. High Fat, Low Carbohydrate Diets of Children Risk of Obesity In the United States and Canada, there is evidence that children are becoming progressively overweight (Flegal, 1999; Gortmaker et al. Furthermore, Serdula and coworkers (1993) reviewed a number of longitudinal studies with vary- ing cut-off levels for obesity and concluded that 26 to 41 percent of obese preschool children and 42 to 63 percent of obese school-age children became obese adults. Clinical evidence of disease associated with excess body weight, reduced physical activity, or high dietary fat intakes, however, are generally absent. The evidence for a role of dietary fat intakes in pro- moting higher energy intakes and thus promoting obesity in young chil- dren is conflicting. A positive trend in energy intake was associated with an increased percent of energy from fat for children up to 8 years of age (Boulton and Magarey, 1995). A positive correlation between fat intake and fat mass has been reported for boys 4 to 7 years of age (Nguyen et al. However, several studies showed a positive correlation between dietary fat intake and body fatness in children 8 to 12 years of age (Maffeis et al. The average fat intake of nonobese children was measured to be 31 to 34 percent for children 9 to 11 years old, whereas the average fat intake of obese children was 39 percent of energy (Gazzaniga and Burns, 1993). A positive association between fat intake and several adiposity indices were observed, but only for up to 35 percent of energy (Maillard et al.

The emergence and re-emergence of diseases has become a wildlife conservation issue both in terms of the impact of the diseases themselves and of the actions taken to control them aurogra 100mg without a prescription. Some diseases may be significant sources of morbidity and mortality of wetland species and in some cases (e buy aurogra 100mg otc. There are many disease types, including: infectious, toxic, nutritional, traumatic, immunological, developmental, congenital/genetic and cancers. Disease is often viewed as a matter of survival or death when, in fact, effects are often far more subtle, instead affecting productivity, development, behaviour, ability to compete for resources or evade predation, or susceptibility to other diseases factors which can consequentially influence population status. Well functioning wetlands with well managed livestock, with little interface, with well managed wildlife should provide human wetland dwellers with the ideal healthy environment in which to thrive. Disease is an integral part of ecosystems serving an important role in population dynamics. However, there are anthropogenic threats affecting wetlands including climate change, substantial habitat modification, pollution, invasive alien species, pathogen pollution, wildlife and domestic animal trade, agricultural intensification and expansion, increasing industrial and human population pressures including the interface between humans and domestic and wild animals within wetlands, all of which may act as drivers for emergence or re-emergence of diseases. Wetlands are meeting places for people, livestock and wildlife and infectious diseases can be readily transmitted at these interfaces. Stress is often an integral aspect of disease capable of exacerbating existing disease conditions and increasing susceptibility to infection. There are a broad range of stressors including toxins, nutritional stress, disturbance from humans and/or predators, competition, concurrent disease, weather and other environmental perturbations. Stressors can be additive, working together to alter the disease dynamics within an individual host or a population. Impacts of disease on public and livestock health, biodiversity, livelihoods and economies can be significant. The emergence and re-emergence of diseases has become a wildlife conservation issue both in terms of the impact of the diseases themselves and of the actions taken to control them. Some diseases may be significant sources of morbidity and mortality of wetland species and in some cases (e. Clearly defined roles and responsibilities are required to ensure effective management which can deliver a range of benefits to stakeholders. Risk assessments are valuable tools for animal health planning and serve to identify problems/hazards and their likely impact thus guiding wetland management practices. Good local, national and regional surveillance data are needed for robust risk assessments. Multidisciplinary advisory groups provide a broad range of benefits for disease prevention and control. Their role is to review epidemiological and other disease control information, inputting to the activation of agreed contingency plans and advising the appropriate decision makers on future contingency planning. Contingency plans aim to consider possible emergency disease management scenarios and to integrate rapid cost effective response actions that allow the disease to be prevented and/or controlled. It is important that wetland managers identify stressor risks within their site and the broader catchment/landscape, and understand that these may change over time. Once these factors are identified, they can be managed and/or their impact mitigated, as appropriate. Disease zoning (although challenging in wildlife and/or aquatic systems) can help control some infectious diseases through the delineation of infected and uninfected zones defined by sub-populations with different disease status. Buffer zones separating infected and uninfected zones may consist of physical barriers, an absence of hosts, an absence of disease vectors or only immune hosts e. The movement of infected animals to new areas and populations represents the most obvious potential route for introduction of new/novel infections. The risk of transmission and spread of disease can be minimised by conducting risk assessments and following certain standardised national and international guidelines and regulations for moving, relocating and/or releasing animals. A disease risk analysis should be conducted for any translocations for conservation purposes. Biosecurity in wetlands refers to the precautions taken to minimise the risk of introducing infection (or invasive alien species) to a previously uninfected site and, therefore, preventing further spread. Infectious animal diseases are spread not only through movement of infected hosts but also their products e. Constructed treatment wetlands can assist greatly in reducing risks from contaminated wastewaters.
