Nutritional challenges for emerging populations

Nutrition is the central component in health promotion as nutrition is needed for our body to grow, develop and maintain the normal functioning of the body.It is an essential aspect of living a balanced lifestyle. Food is readily available in most of  Western society, and it is frequently highly refined and high in calories, fat, and sugar These foods are also less costly than healthier alternatives, making nutritious choices more difficult to come by for low-income families and individuals.Food plays an important role in everyday social life, often taking center stage at parties, meetings, and other activities.(Grand Canyon University, 2018 ) Nutritional challenges for emerging populations

The most nutritional challenges for emerging population as people are very busy to take proper diet and nutrition and hence they lack the essential requirements of the daily intake which causes various diseases, obesity etc. Malnutrition has become more common in the United States in recent years. The majority of people believe that eating fast food in fastfood restaurants is less expensive and more convenient. Furthermore, they find it difficult to eat vegetables and fruits because they are costly and time consuming to prepare.The socio-economic factors also have impact on the deficiency diseases because people are unable to avail better food for themselves.(Homeworklib,n.d). Nutritional challenges for emerging populations

The nutrition deficiency causes malnutrition in which people become weak, and becomes more prone to many of diseases. The excess of nutrition causes toxicity for example, too much of vitamin A causes vitamin toxicity, therefore, nutrition should be maintained at optimum levels to avoid such conditions.

Dietary reference intakes (DRIs) are quantitative, nutrient intake–based standards used for assessing the diets and specific nutrient intakes of healthy individuals and populations and for informing national nutrition policy and nutrition programs. Because nutrition needs vary by age, sex, and physiological state, DRIs are often specified for healthy subgroups within a population. Diet is known to be the leading modifiable risk factor for chronic disease, and the prevalence of chronic disease is growing in all populations globally and across all subgroups, but especially in older adults. It is known that nutrient needs can change in some chronic disease and other clinical states. Disease states and/or disease treatment can cause whole-body or tissue-specific nutrient depletion or excess, resulting in the need for altered nutrient intakes. In other cases, disease-related biochemical dysfunction can result in a requirement for a nonessential nutrient, rendering it as conditionally essential, or result in toxicity for a food component at levels usually tolerated by healthy people, as seen in inborn errors of metabolism. Here we summarize examples from a growing body of literature of disease-altering nutrient requirements, supporting the need to give more consideration to special nutrient requirements in disease states.

In 2010, diet was shown to be among the leading risk factors for disability and nonfatal diseases, including chronic diseases, in the United States. In 2014, it was estimated that 60% of adult Americans had ≥1 chronic condition and 40% had multiple chronic diseases. Historically, the outcomes of investigations of uncomplicated nutritional deficiencies, those that can be resolved by increasing the intake of a single nutrient in virtually all individuals, have been used to establish Dietary Reference Intakes (DRIs). Diseases of nutrient deficiency arise when there is insufficient access to the amount of nutrient necessary for normative physiological function. Diseases of nutrient deficiency are now uncommon in the more developed parts of the world, but there is increasing interest in the role that diet can play in the prevention and management of chronic diseases.

DRIs in the United States and Canada reflect intake levels that sustain adequate nutriture for physiological function in healthy populations. DRIs have been derived for all essential nutrients and some nonessential food components, e.g., fiber. These established intake levels support physiological processes, including metabolism, and prevent diseases of deficiency and/or reduce risk of chronic disease onset. The DRIs provide guidance for meeting nutrient needs and avoiding excess intakes from diets and the food system, respectively, for both individuals and populations. The near disappearance of essential nutrient deficiencies in the United States and Canada and the widespread use and regulatory applications of reference values in public health, clinical, and educational settings document the efficacy of the guidance provided by DRIs, the impact of the evidentiary evaluations on which the DRI values are based, and their important roles in health and related regulatory applications.

DRIs consist of various reference values that enable the assessment of the dietary intakes and nutritional status of healthy individuals and/or populations. The Estimated Average Requirement (EAR) is defined as the intake level needed by half of the healthy individuals within a defined population or subgroup to meet a specified outcome. The Recommended Dietary Allowance (RDA) is defined as the average daily level of intake that meets the requirements of 97.5% of healthy people within a defined population, and its value is 2 SDs above the EAR, based on the assumption that expected interindividual variation is distributed normally. The tolerable upper intake level (UL) is the highest maximum daily habitual intake level that is unlikely to cause adverse health effects. The DRIs also include recommendations for macronutrient and energy intakes. There are excellent reviews on the processes and considerations for establishing DRIs and their use in nutrition policy and programs and public guidance.

In response to the growing burden of chronic disease, the National Academies of Sciences, Engineering, and Medicine developed a consensus report, Guiding Principles for Developing Dietary Reference Intakes Based on Chronic Disease, which addresses the challenges of establishing DRIs and presents a framework for using chronic disease endpoints. This report was guided substantially by an earlier report sponsored by Health Canada and several health-related US federal agencies Nutritional challenges for emerging populations
