Estimated Average Requirement (EAR) is the average daily nutrient intake level that is estimated to meet the requirements of half - 50% - of the healthy individuals in a particular life stage and gender group.
Because the needs of the other half of the population will not be met by this amount, the EAR is increased by about 20% to arrive at the RDA.
Before setting the EAR, a specific criterion of adequacy is selected, based on a careful review of the literature. When selecting the criterion, reduction of disease risk is considered along with many other health parameters.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques (i.e., a genetically engineered organism). GMOs are used to produce medications and genetically modified foods, and are widely used in scientific research and the production of other goods.
A more specifically defined type of GMO is a "transgenic organism." This is an organism whose genetic makeup has been altered by the addition of genetic material from an unrelated organism. Typically GMOs are organisms whose genetic makeup has been altered without the addition of genetic material from an unrelated organism.
