Question and answer
Where might you find dietary recommendations? What are the recommended dietary allowances (RDA)? What are dietary reference intakes (DRIs)?
The Dietary Reference Intake (DRI) is a system of nutrition recommendations from the Institute of Medicine (IOM) of the U.S. National Academy of Sciences. [ The DRI system is used by both the United States and Canada and is intended for the general public and health professionals. Applications include: Composition of diets for schools, prisons, hospitals or nursing homes, Industries developing
new food stuffs, Healthcare policy makers and public health officials. The Recommended Dietary Allowance (RDA) was developed during World War II by Lydia J. Roberts, Hazel Stiebeling and Helen S. Mitchell, all part of a committee established by the United States National Academy of Sciences in order to investigate issues of nutrition that might "affect national defense" (Nestle, 35).[1] The committee was renamed the Food and Nutrition Board in 1941, after which they began to deliberate on a set of recommendations of a standard daily allowance for each type of nutrient. The standards would be used for nutrition recommendations for the armed forces, for civilians, and for overseas population who might need food relief. Roberts, Stiebeling, and Mitchell surveyed all available data, created a tentative set of allowances for "energy and eight nutrients", and submitted them to experts for review (Nestle, 35). The final set of guidelines, called RDAs for Recommended Dietary Allowances, were accepted in 1941. The allowances were meant to provide superior nutrition for civilians and military personnel, so they included a "margin of safety." Because of food rationing during the war, the food guides created by government agencies to direct citizens' nutritional intake also took food availability into account. ]

Weegy: The Department of Nutrition for Health and Development, in collaboration with FAO, continually reviews new research and information from around the world on human nutrient requirements and recommended nutrient intakes. [ This is a vast and never-ending task, given the large number of essential human nutrients. These nutrients include protein, energy, carbohydrates, fats and lipids, a range of vitamins, and a host of minerals and trace elements. Many countries rely on WHO and FAO to establish and disseminate this information, which they adopt as part of their national dietary allowances. Others use it as a base for their standards. The establishment of human nutrient requirements is the common foundation for all countries to develop food-based dietary guidelines for their populations. Establishing requirements means that the public health and clinical significance of intake levels – both deficiency and excess – and associated disease patterns for each nutrient, need to be thoroughly reviewed for all age groups. Every ten to fifteen years, enough research is completed and new evidence accumulated to warrant WHO and FAO undertaking a revision of at least the major nutrient requirements and recommended intakes. Activities and outputs The following major revisions of nutrient requirements, including their role in health and disease, have been undertaken and published in the last four years: Trace elements in human nutrition and health (WHO/FAO/IAEA), WHO, Geneva 1996 Fats and oils in human nutrition (FAO/WHO), FAO, Rome 1994 Preparation and use of food-based dietary guidelines (WHO/FAO), WHO, Geneva 1996 Carbohydrates in human nutrition (FAO/WHO), FAO, Rome 1998 Forthcoming outputs During the 1980s WHO and FAO reviewed the requirements for protein, energy, vitamin A, folate, iron, and several other vitamins and minerals. With regard to vitamins and minerals, there is enough new research to once again justify updating our information on the subject. ]

12. What are some dangers associated with dieting?
Weegy: ?One of the main dangers of dieting is the development of a nutritional deficiency. This can occur from following a fad diet or eating too little. ?Eating disorders~ often begin with caloric restriction. [ The individual begins a normal type of diet or exercise program in a healthy attempt to lose weight but becomes obsessed with weight loss. ?Yo-yo dieting is the process of losing weight by dieting, only to gain the weight back. The cycle is often repeated again and again. Yo-yo dieting has also been found to be associated with increased risks of diabetes, heart disease, high blood pressure and depression. Read more: ] User: 16. How does today’s society affect our nutritional habits? User: 15. Consider your personal dietary habits. What are some modifications you might make to promote good health? Weegy: Coronary Heart Disease. Experts believe that extreme fluctuations in body weight may increase the risk for coronary heart disease. These weight changes don't have to be the result of chronic yo-yo dieting to be dangerous. [ A serious illness, personal crisis or other traumatic event that triggers sudden weight loss followed by rapid weight gain can have the same detrimental effects. That is what Kelly Brownell, Ph.D., of the University of Pennsylvania, found from analyzing several large population studies of the incidence of heart disease. "There is enough evidence to be concerned and to require more research on the issue," Dr. Brownell said. ] (More)
